Case:
Customer Dell 2600 server, five plates, Windows operating systems, using NTFS file systems, raid5, raid damage, data cannot be used.Need to restore all data.
Solution:
The engineer puts the current non -heat -reserve hard disk with a well -operated state of operation to a safe storage with redundant functions. For hard disks with physical problems, it is necessary to recover in accordance with the corresponding faulty type.The data of the hard disk is also backup to safe storage.Analyze all the hard disk mirrors that have been fully backup to determine the original structural parameters of the fault RAID, and at the same time determine the offline situation of each hard disk in the fault RAID.Based on the analysis of the RAID parameters and offline hard disks, the RAID data is constructed in only reading the environment, and the basic logical verification of the virtual RAID constructed is to determine the general structure of the file system to produce a complete mirror.A complete logical analysis and verification of the RAID image of the backup production. If the file system in the image is still inconsistent, it is repaired according to the solution of the corresponding file system damage, until the data needed by the user.
