Case:
Array capacity: 850G failure description: 4 300G hard disk groups are raid5, and the disk array has a disk. When the hard disk is replaced by the hard disk as a repuid, it does not succeed, and the system cannot enter.
Solution:
Recovery process: First, the engineer first draws out the hard disk and mark it in order; second, the 4 hard disk is detected, and two of the hard disks are found in the physical bad disk; third, the hard disk with a bad tract is mirroring.Then, the other two hard disks form a virtual RAID array through algorithms; fourth, the final export data; fifth, data verification success.Restore time: 8 -hour recovery results: disk data recovery successfully.
