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.

Implementing the innovation-driven development strategy and promoting "mass entrepreneurship and innovation" is a major deployment made by the CPC Central Committee. As for starting a business, we have heard the story that some entrepreneurs often raise millions of dollars and get rich overnight. Is it really that easy to start a business? It is also said that the success rate of starting a business is less than 1%, and a startup enterprise may face death if it is not careful. Is entrepreneurship really that terrible? The series report "Entrepreneurship on the Road" tells the ups and downs of these young people’s entrepreneurial stories.

On February 18th, the service personnel of Xushui Meteorological Bureau in Baoding City, Hebei Province came to Beiqinggong Village, Zhengcun Town, to investigate the demand for meteorological services for onion planting, and to protect the characteristic industries.

Service personnel walked into the greenhouse, had in-depth communication with growers, understood the demand for meteorological services, and reminded growers to pay close attention to the latest meteorological forecast and early warning information in view of the recent low temperature and windy weather, so as to make greenhouse management more scientific and effective.

On February 18th, the meteorological service personnel of Xushui Meteorological Bureau inspected the growth of shallots. Li Anqi photography

Combined with the meteorological service demand learned this time, Xushui Meteorological Bureau will make special meteorological service materials and send them to growers through SMS, WeChat and other channels in time, so as to contribute meteorological power to increase agricultural production and farmers’ income.

　　Store grain in the ground, and store grain in technology. Today, agriculture is becoming a promising industry, and farmers are becoming attractive occupations.

　　The autumn wind bursts, setting off layers of rice waves and bringing the fragrance of rice. Approaching the edge of the field, waist-high rice is neatly spread out and extends to the foot of the distant mountain. In the rice field, several harvesters are running at full power and the roar is endless. On the ridge of the field, farmers hold mobile phones to check the growth of rice and the progress of harvesting, and their faces are filled with the joy of harvest. When I came to the 68th regiment of Kekedala City, the fourth division of Xinjiang Production and Construction Corps, a picture of autumn harvest in full swing came to my eyes.

　　The 68th regiment is located in Ili Valley, with fertile soil and abundant irrigation water. Thanks to superior natural conditions, the local area began to explore the cultivation of rice very early. However, due to the lack of advanced planting concepts and technical support, farmers have been exploring for a long time. The variety of rice in the field is mixed, and the height of rice seedlings is uneven, which is not only difficult to manage and protect, but also inefficient. Both the practical needs of increasing farmers’ income and the long-term overall situation of comprehensively promoting rural revitalization have put forward new and higher requirements for improving production technology.

　　Store grain in the ground, and store grain in technology. With the help of modern production technology, local rice planting has embarked on the road of intelligent production. The intelligent agricultural system has made the days of "steaming the summer heat and rusting the country, burning the sun on the back" gone forever. With the help of modern information technology, every field and every seedling has been monitored all the time, and the information such as soil humidity, pH value and rice seedling growth can be seen at a glance. Through the big screen of smart agriculture, technicians can analyze the situation of water and fertilizer, pests and diseases according to the data fed back by remote sensing. Under the precise guidance of data, intensive cultivation, accurate fertilization and reasonable irrigation have replaced extensive management, and watering and fertilization can be completed by machinery without leaving home. From "looking up to heaven for dinner" to "looking up to heaven for management", the unique natural endowment of Yili River Valley is being transformed into the development advantage of rural revitalization.

　　In the process of technology application, we are also faced with a task of coordinating agricultural production with environmental protection. For example, in Bole City, Xinjiang, in the past, planting corn had to go through fixed processes such as plowing and film mulching. When the wind blows over the newly turned land, it will raise dust all over the sky, and the broken plastic film will remain in the ground, which will not only be difficult to decompose, but also cause soil hardening. With the improvement of agricultural technology, farmers began to experiment with corn protective no-tillage technology. Not clearing the straw and plowing the land before cultivation not only reduces the loss caused by land ploughing, but also eliminates the use of plastic film, which not only saves a lot of costs, but also reduces land pollution and protects farmland and surrounding agricultural environment. Crops and land have achieved a virtuous cycle of planting in the middle and planting in the middle.

　　The introduction of advanced agricultural technology has enabled farmers to see the broad prospects of agricultural development and stimulated the enthusiasm, initiative and creativity of production. At first, the popularization of corn conservation no-tillage technology was not smooth. A farmer planted 100 mu with the mentality of giving it a try. When harvesting, he found out that "the yield per mu is more than 100 kilograms, and the cost has dropped, and the 200 yuan per mu is at least increased", and finally he decided to adopt protective no-tillage technology. Since the beginning of this year, the local promotion area has exceeded 30,000 mu. At harvest time, looking at the full corn in the field, the local people smiled.

　　From the foot of Tianshan Mountain to the Ili River, from desert oasis to vast grassland … … In more places in Xinjiang, agriculture has caught the express train of technological progress, production has become more and more convenient, and people’s lives have become more and more affluent. Today, agriculture is becoming a promising industry, and farmers are becoming attractive occupations. Better application of science and technology, agricultural science and technology to help rural revitalization, the pace towards agricultural and rural modernization will be more stable, and beautiful countryside, with strong agriculture, beautiful countryside and rich farmers, will gradually approach.

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 afternoon of April 10th, General Secretary of the Supreme Leader visited Yazhouwan Seed Laboratory and Sanya Ocean Research Institute of China Ocean University successively in Sanya, Hainan Province, to learn about Hainan’s support for seed industry innovation and the development of marine science and technology.

　　Standing at a new historical starting point, "China’s economic and social development and improvement of people’s livelihood need scientific and technological solutions more than ever before, and it is even more necessary to enhance the first driving force of innovation."

　　Since the 18th National Congress of the Communist Party of China, the General Secretary of the Supreme Leader has visited the frontier of scientific and technological innovation for many times, and expounded the great strategic significance of scientific and technological innovation with vivid metaphors for many times.

　　"This ‘ Gold pole ’ I understand it as agricultural modernization. "

　　General Secretary of the Supreme Leader once told such a story. At that time, he was hungry and asked the people around him, what kind of life do you think is the best, and what are the specific goals? Try harder and think boldly about what is higher. "Their answer is — — I will carry a gold pole when I go up the mountain to work in the future! " "This ‘ Gold pole ’ I understand it as agricultural modernization. " The words of the Supreme Leader’s General Secretary contain true feelings.

　　"To solve the problem of eating, the fundamental way out lies in technology." The "golden pole" bears the farmers’ "money bag" at one end and the people’s "rice bag" and "vegetable basket" at the other. Agricultural modernization is based on seeds. "A seed can change a world, and a technology can create a miracle." The General Secretary of the Supreme Leader pointed out that we should make up our minds to develop the national seed industry, pay close attention to cultivating excellent varieties with independent intellectual property rights, and ensure national food security from the source. During this inspection in Hainan, the General Secretary made a special trip to Yazhouwan Seed Laboratory. Yazhouwan Seed Laboratory, established in May 2021, as a public scientific research platform built by Sanya Yazhouwan Science and Technology City, relies on and serves the national Nanfan Scientific and Research Breeding Base, and is guided by seed innovation and seed industry development, helping the high-quality innovation and development of seed industry in China.

　　General Secretary of the Supreme Leader profoundly pointed out, "Only by combining scientific and technological achievements with national needs, people’s requirements and market demand and completing the triple jump from scientific research, experimental development and popularization and application can we truly realize innovation value and realize innovation-driven development."

　　At the symposium of scientists in September 2020, the general secretary pointed out that "accelerating scientific and technological innovation is the need to realize people’s high-quality life" and "in order to meet people’s yearning for a better life, more scientific and technological innovations involving people’s livelihood must be introduced". It is on this occasion that the general secretary put forward new requirements for the vast number of scientists and scientific and technological workers to "face people’s lives and health." During the "Thirteenth Five-Year Plan" period, China has made a number of major scientific and technological achievements in the field of people’s livelihood science and technology. Integrated whole-body positron emission/magnetic resonance imaging equipment, rice breeding accelerators in unmanned plant factories and other scientific and technological innovations for people’s lives and health have been continuously unveiled and applied to a better life.

　　"Scientific and technological innovation, like a lever to incite the earth, can always create unexpected miracles."

　　In June, 2014, at the 17th Academician Conference of China Academy of Sciences and the 12th Academician Conference of China Academy of Engineering, General Secretary of the Supreme Leader pointed out: "Scientific and technological innovation, like a lever to shake the earth, can always create unexpected miracles. The development of contemporary science and technology fully proves this process. "

　　Scientific and technological innovation makes the deep sea no longer mysterious. In April, 2018, General Secretary of the Supreme Leader visited the Institute of Deep Sea Science and Engineering of China Academy of Sciences in Sanya, Hainan, to learn about China’s first 10,000-meter seabed exploration in the Mariana Trench, and went into the exhibition area of deep-sea exploration equipment with great interest to see all kinds of deep-sea diving high-tech equipment.

　　Technological innovation makes space no longer far away. Just last month, the second class of "Tiangong Classroom" was held in China Space Station, and the astronauts of Shenzhou XIII gave another wonderful space science class. During more than 170 days of space flight, three astronauts, with the support of ground technicians, carried out a number of scientific and technological experiments and application projects, setting many "firsts" and "firsts".

　　Scientific and technological innovation is the strategic support to improve social productivity and comprehensive national strength. Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with the Supreme Leader as the core has made a major strategic choice of "innovation must be the first driving force for development" and implemented the innovation-driven development strategy.

　　"Life Gate", "Bull’s Nose", "Heaviest Weapon of the Country", "Fixed Sea Needle" and "Unique Weapon" … … Nowadays, China has started a new journey of building a socialist modern country in an all-round way, and the position of scientific and technological innovation in the overall development of the party and the country is more prominent.

　　"Innovative achievements should benefit the whole world, and should not become treasures buried in caves."

　　In November 2019, when the Chairman of the Supreme Leader met with foreign representatives attending the 2019 Innovation Economic Forum, he pointed out that "no country can become an independent innovation center or enjoy innovation results exclusively. Innovations should benefit the whole world and should not be a treasure buried in a cave. "

　　Fungus and grass technology, which has been popularized in more than 100 countries around the world, is a dazzling treasure out of the cave. With the long-term concern of the Supreme Leader, the fungus-grass technology of "replacing wood with grass" has gone out of China from Fujian to the world, which has played an important role in promoting local development and people’s well-being, and has been widely welcomed by developing countries.

　　"China is willing to work with all parties concerned to continue to contribute China’s wisdom and China’s plan for the implementation of the UN’s 2030 Agenda for Sustainable Development, so as to make mushroom technology benefit the people of developing countries ‘ Happy grass ’ ！” In September last year, the Chairman of the Supreme Leader pointed out in his congratulatory letter to the 20th anniversary of foreign aid to fungi and grasses and the International Cooperation Forum for Sustainable Development.

　　The world today is experiencing a great change that has never happened in a hundred years, and the domestic and international environment facing China’s development has undergone profound and complex changes. In the face of fierce international competition and against the background of rising unilateralism and protectionism, General Secretary of the Supreme Leader is far-sighted: "Scientific and technological achievements should benefit all mankind, and should not be a means to restrict or contain the development of other countries."

　　China’s scientific and technological innovation, not alone, nor narcissistic. "Promoting sustainable development through scientific and technological innovation has become the only way to solve some important global issues of concern to all countries." "We have expanded open cooperation in the field of science and technology, actively participated in solving major challenges facing mankind, and worked hard to promote scientific and technological innovations to benefit more countries and people." … … China’s scientific and technological innovation has conveyed China’s wisdom and contributed to China’s plan, which is promoting mutual benefit and sharing, unity and cooperation among all countries, creating a bright future together, and making continuous progress towards building a community of human destiny.
