Case:
Customer Dell MD3000 server, using RAID5 made by 15*1T, storage suddenly storage, so the hard disk was bright yellow light. Then the server could not be accessed. After testing by the engineer, it was found that the No. 4 hard disk was severely damaged. The No. 3 hard disk had a small amount of bad sectors, and other hard disks were normal.
Solution:
The engineer uses the data of each plate to make a mirror.Analyze RAID information through the structural characteristics of the file system, remove the bad hard disk, and build a virtual RAID bad realm; detect the data, and then import all data into the newly prepared storage of customers, which is completely normal.
