Case:
There are 8 plates on the server server of the Meteorological Bureau to make a set of RAID6, of which No. 1 and No. 5 turned on red lights. They were not found in time. Later, it was found that the 2nd plate was turned on.The system is Windows 2008 Server.
Solution:
After the hard disk was tested, the plate No. 1 and No. 5 disk were scratched, which was severely damaged by severe hard disk and the medium was not repaired.A small amount of hard disk bad sectors appear on the 2nd plate, which can be mirror.Other hard disk mirrors are smooth.Data recovery analysis: Because the entire server 8 plates do a set of RAID6, theoretically the lack of two disks can restore the data. Whether the recovery data is correct depends on the sequence of damage in the No. 1 and No. 5 and No. 2 disk.If the No. 1 and No. 5 disk are bad first, and the No. 2 plate is later bad.Essence
