How to troubleshoot RAID 5 in the server

　　Due to the continuous progress of technology, different types of servers have different treatment methods after RAID 5 failure.

　　At present, the network topology structure of large-scale application programs generally adopts C/S structure or B/S structure, and at least one server with a large database needs to be placed in the central computer room. Considering the security and reliability of the server, RAID (Redundant Array of Inexpensive Disks) is usually used for redundant backup of the server’s disks. Among them, RAID 5 array level is parity disk array without independent parity disk, which adopts data blocking and independent access technology, can process multiple access requests in parallel on the same disk, and allows any hard disk in the array to fail.

　　In practical application, due to some inevitable objective reasons, some array failures may occur. The most common situation is that the hard disk automatically goes offline, and the online status is displayed as DDD (invalid disk drive), and the hard disk has physical or logical failure. If it is a physical fault, only the hard disk can be replaced; If it is a logical fault, it can be repaired by targeted technology to restore the online state of the hard disk, continue to maintain the striped distribution of the hard disk data in its original array, and continue the consistency of the data storage system.

　　However, the data recovery of some old HP servers (such as HP LH6000) is different from that of new HP servers (such as HP ProLian series servers). Therefore, different servers handle RAID 5 failures differently. I have been in contact with the data failure of RAID 5 array card caused by unexpected power failure of two servers, and solved the problem by adopting different strategies.

Fault repair

　　One is HP LH6000 server, and four 18GB hard disks are made into RAID 5 disk array, and its array card is NetRaid. The other is HP ProLian ML370 server. Four 146GB hard disks are made into RAID 5 disk array, and its array card is Smart Array 642 with Hot Spare hard disk. Both operating systems are Window 2000 and the database is Server 2000.

　　The fault of HP LH6000 is as follows: one hard disk is flashing red light, and the machine is still running normally, but it will not be long before the system can not run normally, and then it is found that the red light of another hard disk is flashing.

The solution is as follows:

　　1. start the server, and press Ctrl+M to enter the NetRaid management program when self-checking to the array. Check the array information and find that the hard disk status is Failed, and use the modified configuration to forcibly set a hard disk to OnLine. Restart the server, the hardware self-check before entering the system is invalid, and the startup fails.

　　2. Start the server, and press Ctrl+M to enter the NetRaid management program when self-checking to the array. Select the disk array, manually Fail the hard disk that was originally hung OnLine, and then manually set another Failed hard disk to OnLine, and restart the server to enter the system.

　　3. After checking that the system and database are running normally, enter the array configuration tool and manually set the Failed hard disk to Rebuild, and then restart the server after 100% reconstruction. All arrays and systems are restored to their original state.

　　Another server running ERP system (HP ProLiant ML370) is configured as a RAID 5-level disk array by four 146GB hot-swappable hard disks through RAID cards (Smart array array cards). One of the hard disks suddenly broke down during operation. Server RAID 5 automatically enables the Hot Spare hard disk to logically replace the damaged hard disk. The data access task of the whole hard disk still runs completely in the original reading and writing process sequence, and the application program and database have no influence.

　　Check the hard disk status through the ACU tool that comes with HP, and find that the hard disk with red light warning is offline. If there are two red lights on Raid 5 in HP ProLiant server, it indicates that the system has crashed and the database cannot be accessed, but the system will not shut down automatically. When the second hard disk is red, the data can’t be recovered by conventional means, so we have to pay a professional third-party data recovery company to recover the data.

　　Therefore, for the old HP LH6000 series servers, the array design is quite different from that of the current HP ProLiant series servers. As far as the operation method is concerned, there are many options for the array operation method of HP LH6000 server, including deleting the array again and rebuilding it after the array fails, and the initialization is also manually selected. However, the initialization of HP ProLiant series server array is automatically performed in the background after the array is configured, so the ProLiant series server cannot reconfigure the array after an array error.

　　The HP LH6000 server will cause the disks in the array to be disconnected for other unexpected reasons, so the maintenance personnel can manually choose Online or Offline, Rebuild, etc. to restore the data. However, the current HP ProLiant series servers will no longer have the phenomenon of disk disconnection in the array like the old servers, so when the hard disk is red, it is basically damaged and needs to be replaced. Of course, you can choose to Rebuild the hot-plug hard disk and see if the hard disk can be used for a while.

Do a good job of technical backup

　　From the above two examples, it can be seen that the troubleshooting of Raid 5 disks of servers of the same brand and different series is different because of their different embedded technologies. But after Rebuild the data, the data was saved, from which the following experiences can be drawn:

　　We believe that any advanced technical means is not foolproof. If you want to ensure data security, you must do a good job of backup, and it is best to do a remote backup of the database once a day. Spare at least one new hard disk. It should be pointed out that the hard disk that joins the array must be greater than or equal to the capacity of the failed hard disk.

　　If conditions permit, the array creation scheme of "RAID 5+ hot spare" is recommended. This way, we have two chances to replace the hard disk before the data is lost. For general applications, only RAID 5 is needed, which can provide data access performance, reliability and maximum disk space at the same time.

　　Administrators must always observe the status of the array, including the yellow warning light of the disk array and the drive status in the management software. Trouble shooting in time. No matter what level of array, data backup should be done before troubleshooting.

　　Throughout modern history, smallpox has held the top spot in killing human beings.

　　Smallpox is also the first infectious disease eliminated by human beings.

　　When future generations are exploring what killed smallpox, the trekking about how human beings overcome diseases step by step has merged into the long river of human medical history.

　　It is necessary for us to wade into this river at any time, go back to the way we came and find hope for the future.

　　The pockmarked emperor and the milkmaid

　　It is mentioned in Huangdi Neijing that "poison" should be used to treat diseases, and the so-called "fight poison with poison". Traditional Chinese medicine began to use this method to deal with smallpox, which existed during the Tang and Song Dynasties. Doctors take out the serous fluid from the abscess of smallpox patients and implant it into the body of healthy people for prevention and treatment, which is called human pox vaccination.

　　During the Wanli and Apocalypse years of Ming Dynasty, various books about human pox appeared. By the Qing dynasty, the method of preventing smallpox by human pox vaccination was widely promoted. Kangxi, the "pockmarked-faced emperor" who had suffered from smallpox, set up a pox clinic under the Tai Hospital and recruited famous doctors. Also in Beijing, a special "acne check chapter Beijing" is set up to take charge of the Eight Banners’ acne prevention. He specially sent people to welcome Ayla Zhang, a well-known folk vaccinia doctor, into the palace to vaccinate the royal family and banners.

　　Jared diamond, an evolutionary biologist and anthropologist, once revealed how the human body can defeat the virus: in the process of resisting a certain pathogen that infects the human body, the human body will gradually form specific antibodies, which makes it unlikely to be infected by the same pathogen again after recovery.

　　In the thousands of years of confrontation between human beings and smallpox, the latter has occupied an absolute advantage for a long time, and "pockmarked face" is so common that people without pockmarked face become special.

　　The 18th century was the age when smallpox ravaged Europe, and the British doctor edward Cenna (1749-1829) devoted himself to studying the solution. He noticed that almost all the female milkmaids had no "pockmarked faces". The beautiful milkmaid aroused Qinna’s curiosity, and he found one thing in common with them — — Cowpox of a milkmaid.

　　Vaccinia is a virus that can be co-infected by humans and animals, but it does no serious harm to cattle and people. There is a saying in the English countryside that "as long as you have suffered from vaccinia, you will not get smallpox".

　　Since 1788, Qinna began to carry out experiments on animals, using vaccinia of dairy women instead of smallpox patients to fight smallpox. For 8 years in a row, the experiment pointed to the same result, and vaccinia can effectively prevent smallpox.

　　On May 14th, 1796, Qinna conducted the first human experiment. He took the serous fluid Sarah Nelmes, a milkmaid, and inoculated it on the arm of phipps, an 8-year-old boy. Two months later, he inoculated phipps with real smallpox slurry. As a result, the boy was not infected with smallpox, and the previous vaccination seemed to have made him immune.

　　In the following two years, Qinna conducted the same human experiment many times, and the results were the same: all children who had had vaccinia were immune to smallpox virus. In 1798, Chennault announced that smallpox could be prevented by vaccination.

　　Vaccinium vaccination spread rapidly around the world. In 1977, Ethiopia recorded the last case of smallpox in human history. On October 26, 1979, WHO officially publicized that smallpox was eradicated all over the world.

　　This is the first time in human history to win the battle against infectious diseases.

　　Fatal bacteria and life-saving bacteria

　　Although the practical application of vaccinia technology is very successful, scientists are not satisfied. People need to explain theoretically why vaccinia can fight smallpox.

　　In the 1950s, chemist Louis Pasteur confirmed the relationship between diseases and germs, and found that specific microbial pathogens could cause specific diseases. Moreover, he found that the long-term growth toxicity of bacteria on artificial culture medium would be weakened, but the immunogenicity still existed.

　　According to this theory, in 1881, Pasteur artificially attenuated Bacillus anthracis with strong immunogenicity and inoculated it into sheep, which finally proved that sheep inoculated with Bacillus anthracis vaccine would not get the disease again.

　　Rabies virus can not be isolated and cultured like bacteria, but Pasteur confirmed that the pathogenic microorganism causing rabies exists in the spinal cord or brain tissue of sick animals. Therefore, he chose rabbit brain for subculture to obtain attenuated strains, and then successfully made live vaccines.

　　With the development of microbiology and immunology, vaccine is really defined as active immunity preparation for preventing infectious diseases, which is made of pathogenic microorganisms (such as bacteria, rickettsia, viruses, etc.) and their metabolites by artificial attenuation, inactivation or genetic engineering.

　　Based on this method, more vaccines can appear. Attenuated live vaccine made by heating inactivation of Vibrio cholerae; After 13 years and 213 generations of continuous culture on the culture medium, attenuated BCG was obtained.

　　With the development of the discipline, some traditional classical vaccine varieties have been further transformed into new vaccines, and some vaccines that cannot be developed with classical technology have found ways to solve the problem.

　　In 1972, recombinant genetic engineering contributed a lot of technical support and gave birth to recombinant gene vaccine. By using DNA recombinant biotechnology, natural or synthetic genetic material which can induce immune response in protein of pathogen shell can be directionally inserted into bacteria, yeast or mammalian cells, and the vaccine can be made after expression and purification. Nowadays, BCG, recombination vaccines, SARS vaccine, HIV vaccine and highly pathogenic avian influenza vaccine are being studied.

　　Conjugate vaccine appeared in 1980s. Scientists linked sugar molecules with protein (toxoid of Clostridium tetanus or diphtheria) by chemical methods, and developed a conjugate vaccine. Vaccines against pneumonia and meningitis are made in this way.

　　Looking at the present, the vaccine that has attracted much attention is none other than nucleic acid vaccine. Nucleic acid vaccine, also known as gene vaccine or DNA vaccine, transports DNA vaccine to human cells through some carrier (such as nanoparticles), which will guide the cells to produce immune active components, and then the cells will "spit out" these active components to stimulate the human body to obtain corresponding immunity, but it will not cause disease.

　　Nucleic acid vaccine can even transfect food cells, such as inserting hepatitis B virus nucleic acid vaccine into the genome of tomato cells, and inoculating the vaccine when eating tomatoes.

　　Scientific and technological progress brings infinite possibilities, and the new exploration of vaccination methods is also the tireless pursuit of scientists. In addition to traditional injection methods, oral administration, skin patch, nasal spray and improved fruit are all targets.

　　A never-ending struggle

　　With the development of immunology research, people have more and more expectations for vaccines, hoping that they will not only "prevent diseases". Researchers are already in action, trying to achieve the effect of treating diseases or preventing diseases from worsening by inducing specific immune responses. Such vaccine products are therapeutic vaccines.

　　There are many therapeutic vaccines that have been studied all over the world: tumor vaccines used for tumor treatment use tumor antigens for active immunization to stimulate the body’s active specific immune response to tumors to prevent the growth, spread and metastasis of tumors; Vaccines used for the treatment of cardiovascular diseases aim at intervening the immune process to prevent the occurrence and development of atherosclerosis (AS). A Swiss biotechnology company said that CYT006-AngQb, a vaccine used to treat hypertension, has a good clinical development prospect … …

　　On the other hand, when human beings are struggling to move forward, the "perpetrators" of infectious diseases are not willing to be silent. Since 1970s, more than 40 infectious diseases have been discovered in the world, such as HIV virus, avian influenza virus, SARS virus, mad cow disease prion, monkeypox virus, Lyme virus, Ebola virus, Legionella, Vibrio cholerae O139 and so on. People’s common influenza viruses are constantly innovating. For example, after the "Spanish flu" caused by H1N1 virus, the "Asian flu" and the "Hong Kong flu" were staged by H3N2 subtype virus. Or a lower-grade flu, it is staged almost every few years in Europe, America and Asia. There are also new viruses that have never met each other, eyeing and hiding in the dark.

　　"The only competitor competing with humans for the dominance of the earth is the virus." The words of lederberg, the winner of the Nobel Prize in Physiology or Medicine in 1958, sounded like an alarm bell. In the past two hundred years, the confrontation between human beings and germs was the fiercest. For the first time, we turned the tables, stood in a pre-emptive position, and seized the throat of the biggest killer of human beings. Compared with the end of the 19th century, the average life expectancy of human beings has been extended for several decades.

　　We have opened the "box" of vaccines. Overcoming the challenge of disease again and again makes us believe that disease creates problems and also provides understanding.

Xinhua News Agency: Vaccine has played a key role in the prevention and control of influenza. At present, influenza has entered the high season. Is it too late to vaccinate now?

Wang Dayan, Director of National Influenza Center, Institute of Virology, China CDC:Among the prevalent respiratory diseases, influenza, COVID-19 and pneumococcal infection all have corresponding types of vaccines. The influenza vaccine has been used in the world and China for decades. Scientific research and vaccination practice have fully proved that the influenza vaccine is safe, effective and a mature vaccine. Influenza vaccination can effectively reduce infection, even if it is infected, it can also reduce the incidence, and even if it is infected, it can also reduce the severity of the disease.

At present, it is the high season of influenza, and it is still effective to vaccinate people who have not been vaccinated with influenza before. It is recommended that you vaccinate with influenza as soon as possible. Here, I especially point out that people over 6 months can be vaccinated with influenza, especially for high-risk people such as children, the elderly and patients with chronic diseases. After being infected with influenza, the risk of severe illness is higher. Vaccination with influenza can effectively reduce the risk of developing into severe illness and death. I hope everyone will actively vaccinate.

Practice at home and abroad has proved that the use of vaccine is one of the most economical and effective preventive measures, and the vaccine is safe. As long as it is vaccinated in professional institutions as required, it can have good results, especially for the elderly and children, and should actively vaccinate against influenza to ensure the normal pace of life and study.

Actress Aya Sugimoto was recently invited to shoot a group of public service advertisements for PETA, an animal protection association. On the 17th, she took a formal photo shoot in a studio in Tokyo.

　　Although she was used to nudity in filming, Aya Sugimoto felt a different sense of tension that day. Only one piece with the words "Fur? It’s better to be naked. "The advertisement board covers her chest. She said," So far, I feel naked is the feeling of wearing another suit, but this time I have a different sense of tension. I seem to have taken off all my clothes. " Having said that, the actress, who is famous for her sexy and erotic lines, still showed a provocative and dangerous expression when facing the camera. "I stopped wearing fur two years ago, hoping I could face the eyes of those dead animals." It seems that Erotic Queen still has a positive attitude and decisive action in environmental protection. I believe this is also the place that PETA invited her to appear in this group of advertisements.

The latest news of the situation in Russia and Ukraine has attracted the attention of all parties.

On February 12, the Global Times quoted the US Wall Street Journal as reporting on February 11 that the General Intelligence Department of the Ukrainian Ministry of National Defense said on the same day that the Russian army was using the "Star Chain" system developed by SpaceX on a large scale at the front line. In response, SpaceX CEO Musk responded urgently, "Some false news said that SpaceX is selling’ Star Chain’ terminals to Russia. This is absolutely wrong. "

On February 12th, local time, the Kremlin responded that elon musk’s "Star Link" satellite Internet system was neither certified for use in Russia nor officially supplied to Russia, so it could not be used.

At present, Musk’s "Star Chain" business is welcoming a big outbreak. According to a source quoted by Bloomberg, it is estimated that SpaceX’s sales in 2024 will increase to about 15 billion US dollars, in which the sales of "Star Chain" business will exceed the launch business, and the number of users of satellite Internet service will exceed 40 million by 2025. SpaceX’s annual income can reach 30 billion US dollars, and the "Star Chain" project will become the most profitable business.

Musk responded urgently.

On February 12, the Global Times quoted the American Wall Street Journal as reporting on February 11 that the General Intelligence Bureau of the Ukrainian Ministry of National Defense said on the same day that the Russian army was using the "Star Chain" system developed by SpaceX on a large scale near the front line of the Russian-Ukrainian conflict, which might weaken a major battlefield advantage of the Ukrainian army.

According to the report, by using the "star chain" system, Ukrainian frontline troops can communicate safely with Internet applications, so that they can keep in touch without relying on mobile phones or radio signals that are more easily monitored by Russian troops.

Andrei Yusov, spokesman for the General Intelligence Department of Ukraine’s Ministry of National Defense, said that Russian troops are "systematically" using "Star Chain" terminals, which are used by Russian 83rd Air Assault Brigade and other troops, which are fighting near the towns of Cris Chivka and Andrevka in Donetsk region of eastern Ukraine.

The statement did not mention how the Russian army obtained these terminals, for example, whether they were purchased from abroad or seized from the Ukrainian army.

This is the first time Ukraine has issued an official statement on Russia’s alleged use of the Star Chain.

Later on December 11, local time, SpaceX CEO Musk responded urgently.

Musk responded that "some false news said that SpaceX is selling’ Star Chain’ terminals to Russia. This is absolutely wrong. "

Musk wrote on the social platform X: "As far as we know, no’ Star Chain’ terminal is directly or indirectly sold to Russia."

On February 12th, local time, the Kremlin also responded that elon musk’s "Star Link" satellite Internet system was neither certified for use in Russia nor officially supplied to Russia, so it could not be used.

Kremlin spokesman dmitry Peskov said in an interview: "This is not our certified system; Therefore, it cannot be officially supplied here, nor is it officially supplied. Therefore, it cannot be officially used in any way. "

Frequently involved in the Russian-Ukrainian conflict

The Global Times quoted The Wall Street Journal as saying that SpaceX had issued a statement on social platform X on February 8, local time, saying that the "Star Chain" satellite service could not be used in Russia, but did not explain whether this service could be used on the Russian-controlled side of the Russian-Ukrainian front line.

A SpaceX spokesperson did not respond to a request for comment on the 11th.

The report pointed out that although the "Star Chain" terminal could not be purchased in Russia, Ukrainian media reported that the Russian army had purchased the equipment in a third country and brought it to the front. In addition, the Russian army may have seized the "star chain" terminal from the Ukrainian army, so that it can access the "star chain" network. Although SpaceX has the ability to track the "Star Chain" users in a specific geographical location, it may be difficult for the company to determine whether the users are Russian or Ukrainian, especially in front-line areas.

The Wall Street Journal said that since Musk decided to provide "Star Chain" service for Ukraine after the outbreak of the Russian-Ukrainian conflict, the use of the "Star Chain" system has always been a politically charged issue.

According to the report, the "Star Chain" system is considered to be crucial to the actions of the Ukrainian army, so that when SpaceX said that it could no longer provide access funds for Uzbekistan in 2023, the US Department of Defense and other Ukrainian supporters were forced to agree to pay the fees to maintain the operation of the service.

In September 2023, Musk said that in the early days of the conflict, he rejected Ukraine’s request to start the "Star Chain" service near Sevastopol, Crimea, in order to avoid SpaceX’s direct involvement in Uzbekistan’s plan to attack Russian ships.

Gwen Shotwell, president of SpaceX, said at a meeting earlier that SpaceX had taken measures to restrict the use of the "Star Chain" system in Ukrainian military operations. She said at the time that the company did not intend to make the "star chain" a weapon.

"Star Chain" Outbreak

SpaceX is a space exploration technology company owned by Musk. Its main business includes orbital rocket launch, manned space flight and satellite Internet service. The satellite Internet service is the star chain service, which aims to provide high-speed Internet connection for users around the world through satellite network.

According to Bloomberg, which previously quoted people familiar with the matter, SpaceX’s revenue from rocket launch and starlink business in 2023 is estimated to be about 9 billion US dollars, and its sales are expected to increase to about 15 billion US dollars in 2024.

According to the report, it is estimated that the sales of "Star Chain" business will exceed the launch business in 2024, which will account for most of SpaceX’s total revenue. By 2025, the number of users of satellite Internet services will exceed 40 million, and SpaceX’s annual revenue will reach 30 billion US dollars. The "Star Chain" project will become the most profitable "Golden Bull" business.

Musk has been trying to use the "Star Chain" business unit as an important source of income to fund SpaceX’s capital-intensive projects.

It is reported that "Star Chain" is a low-orbit Internet constellation plan proposed by SpaceX in 2014, with the goal of building a space-based communication system with global coverage, large capacity and low delay, and providing high-speed Internet services on a global scale.

Statistics show that by the end of 2023, "Star Chain" has been applied in 65 countries, serving over 2.3 million users, an increase of over 1.3 million.

According to the latest report of Cloudflare, a network infrastructure company, compared with 2022, American traffic from "Star Chain" increased by more than 150% in 2023.

From a global perspective, according to the statistics of Cloudflare, the internet traffic in the world increased by 25% in 2023, while the traffic of "Star Chain" was twice as much as this data.

It is worth mentioning that in the past year, Musk has strengthened in-depth cooperation with the US military. The most striking thing is that SpaceX has specially created a service product called "Star Shield" for the US military, and in view of the good performance of "Star Chain" on the battlefield in Ukraine, the US Department of Defense also awarded SpaceX a contract worth 70 million US dollars in September 2023.

According to the contract, the Star Shield network will provide end-to-end services for the military through the Star Chain constellation, user terminals, auxiliary equipment, network management and other related services, and on the basis of the Star Chain data encryption service, the Star Shield has been added with additional encryption technology to ensure the security of data processing of the hosted payload, and SpaceX has become the first provider to provide low-earth orbit satellite services for the US military.

　　On the 5th, the International Olympic Committee banned the Russian delegation from participating in the Winter Olympic Games in Pyeongchang, South Korea, scheduled for February next year, citing Russia’s "systematic manipulation of anti-doping work", but allowed qualified Russian athletes to participate as neutral athletes.

　　Russia strongly opposes this decision of the International Olympic Committee, believing that there is a "political motive" behind it, but it is not eager to fight back and start reflection at the same time. Russian President Vladimir Putin said on the 6th that Russia will not boycott the PyeongChang Winter Olympics, nor will it prevent its athletes from participating in a neutral capacity.

　　[Against multiple sanctions]

　　Thomas bach, president of the International Olympic Committee, decided that the systematic use of stimulants by Russian athletes was "unprecedented destruction" to the Olympic spirit. Russia’s Kommersant reported that the International Olympic Committee suspended the membership of the Russian Olympic Committee and imposed a fine of about $15 million. It also imposed sanctions on a series of Russian sports officials, including banning Russian Deputy Prime Minister and former sports minister Vitaly Mutko from participating in future Olympic-related activities for life and suspending the membership of Russian Olympic Committee President Alexander zhukov in the International Olympic Committee.

　　Russia strongly opposes the decision of the International Olympic Committee. Zhukov said that this is an insult to every Russian athlete. Franz Kline-Cevic, first vice-chairman of the National Defense and Security Committee of the Russian Federation Council and the upper house of parliament, said that sports has long been one of the important areas of international relations. The IOC’s move is aimed at isolating Russia, which will not only deal a heavy blow to the Olympic movement, but also to international relations and even world security.

　　Maria Zacharova, a spokesman for the Russian Foreign Ministry, said that the decision of the International Olympic Committee made all Russian athletes very sad. "The international community did not expect Russia to rise again as a sports power. The world war, the disintegration of the Soviet Union, and sanctions against Russia have not killed Russia, and Russia cannot be killed under any circumstances. "

　　The Russian doping incident began with a documentary broadcast by ARD TV in Germany in 2014, which claimed that doping was rampant in Russian track and field. Dick pound, then president of the World Anti-Doping Agency, then launched an investigation and released the results in November of the following year, saying that Russian track and field circles used banned drugs "systematically".

　　The independent committee appointed by the World Anti-Doping Agency issued reports in July and December 2016, and found that the Russian government manipulated doping inspection, and thousands of athletes were suspected of taking stimulants in the past five years. As a result, Russian track and field athletes lost the qualification to participate in the Rio Olympic Games in the same year, and the Russian delegation was banned from participating in the Rio Paralympic Games.

　　[Condemning political motives]

　　Bach stressed that the decision of the International Olympic Committee was not mixed with any political factors. Putin believes that this decision "looks completely like being directed and has political motives."

　　Sergei Mikheyev, a Russian political commentator and former director of the Center for Political Situation Analysis, believes that the decision of the International Olympic Committee was politically motivated from the beginning. The doping storm will intensify before the Russian presidential election in March next year, with the purpose of destroying Putin’s image, dividing and disintegrating Russian society to the greatest extent and injecting negative emotions into Russia.

　　Mikheyev said that athletes use stimulants in many countries, but they have never encountered such severe collective sanctions. According to him, the World Anti-Doping Agency’s conclusive evidence about the doping incident in Russia only comes from the words of grigori Rodchenkov, the former director of the Moscow and Sochi Doping Testing Laboratory, in an interview in the United States. The so-called Russian government’s doping project is nonsense.

　　CBS and The New York Times broke the news in May last year. In an interview with these two media, Rodchenkov identified Russian athletes’ doping as "government behavior".

　　Mikheyev said that this decision shows that the IOC succumbs to political pressure and can easily become a "political victim". The punishment of the International Olympic Committee is one of the means for the West to contain Russia. Western economic and financial sanctions against Russia, political, military and online suppression of Russia, and so on, are a set of overall strategies.

　　[Reflecting on coping style]

　　Dmitry Peskov, a spokesman for the Kremlin, said on the 6th that the decision of the International Olympic Committee should not be emotional and needs to be studied in depth. Vyacheslav volodin, chairman of the Russian State Duma and speaker of the lower house of parliament, has ordered to study the decision of the International Olympic Committee.

　　Mikheyev believes that Russia will not take boycott measures against the International Olympic Committee. On the contrary, Russia will find some compromise ways to make itself neither weak nor tough and isolated.

　　He said that if Russia could enter the leadership of the World Anti-Doping Agency and strengthen its position in the International Olympic Committee, it would not have to accept the rules of the game imposed by western countries, and it would not have suffered today.

　　Mikheyev said that Russia should reflect on this incident. First, it should resolutely put an end to doping. Secondly, it can consider creating alternative mechanisms while defending its own rights, such as creating a new brand of sports events.

　　He said that the global governance system established by western countries aims to maintain the dominant position of the West and will not consider the interests of other countries. This incident is one of the cases in which the West has effectively used its global governance system, and it has also sounded the alarm for other countries. Countries should use all feasible means to defend their rights in the international system, and should gradually establish alternatives to the global governance system, so that western countries will lose the opportunity to exert pressure.

　　[Free to participate independently]

　　South Korea’s Ministry of Culture, Sports and Tourism issued a statement on the 7th, expressing regret that the International Olympic Committee banned Russia from participating in the PyeongChang Winter Olympics, and hoped that Russian players would participate in the competition in their personal capacity. The statement said that the participation of winter sports athletes from all over the world, including Russian athletes, is the key to the success of the PyeongChang Winter Olympics and the most important factor in practicing the Olympic spirit.

　　IOC President Bach said that while imposing sanctions, the IOC should draw a clear line to protect those innocent Russian athletes. The International Olympic Committee will invite qualified Russian athletes to participate in the competition. They will be called "Olympic athletes from Russia", and the invitation list will be determined after strict examination by a committee.

　　Russian President Vladimir Putin said on the 6th that the Olympic Games is very important for athletes. "If Russian athletes decide to participate in the competition in their personal capacity, we will not make any obstruction.".

　　Some athletes now hope to receive an invitation letter from the International Olympic Committee. Russian media speculated that a number of Russian heavyweight winter athletes, including figure skater Evgeniya Medvedeva and skier Sergei Ustyugov, were expected to be invited. They were younger, had no previous doping scandals and had no criminal record of using illegal drugs.

　　However, if they qualify for the competition, they must wear the competition clothes with the title of "Olympic athletes from Russia", which does not represent Russia. The Russian flag and national anthem will not appear at any ceremony, but the Olympic flag will be raised and the Olympic anthem will be played. (An Xiaomeng) (special feature of Xinhua News Agency)

　　"Clean" athletes who missed the PyeongChang Winter Olympics from the Russian delegation can be invited to participate.

　　BEIJING, Nov. 11 (Xinhua) Hong Kong’s Ming Pao reported that Rene Liu (milk tea) attended a watch event in Hong Kong yesterday as a global spokesperson. She went into battle in a vacuum and appeared in a black dress with a full perspective back. Yesterday, the reporter saw that her waistline was very round. When she went up and down the stairs in high heels, she was immediately assisted by several assistants, and the battle was very big. However, Rene Liu denied pregnancy again yesterday, and even stamped her foot and said, "No (pregnant)! Look at me wearing such high heels! "

　　Rene Liu said that he had arrived in Hong Kong a few days ago to attend a seminar on independent films with Zhang Aijia. She also laughed and said that before she became a watch spokesperson, she was also very punctual. "I will send watches to people around me, and my father and friends will also benefit." Ask her if she gave her husband Zhong Xiaojiang a watch? Although she didn’t want to talk more about her husband, she couldn’t help smiling and saying, "No, but the brand sent us a pair of watches."
