Case:
NAS fails after the abnormal power off.Restarting NAS computers cannot be connected remotely.Management processing or error, customers need all network user data stored in NAS.
Solution:
After the dedicated hard disk tool test, the four disks are intact, and the four disk data mirrors are all on the backup disk. The iODATA uses the Linux operating system, and the system partition file system is EXT3. Using the independent development of Linux analysis tools, after successfully analyzing the Linux system file RAID5 uses the XFS file system to analyze the mirror partition of the entire disk to obtain the detailed parameter parameters of the soft RAID5. The engineer uses the independently developed Linux RAID recovery tool to reorganize the four hard disks, and you can see all the data of iOData. Therefore, write the target mirror file into a single 500G hard disk prepared in advance, and the unknown user directory appears when mounting this XFS file system under Linux. So use the special file system driver to repair the file system, successfully mount 500G data backup hard disk under Linux, copy all the customer’s data, and wait for the customer to verify the data. Customers come to the headquarters from Wenzhou. After inspection, the data recovery is completely successful. For difficult problems, it is best to consult experts in advance. 4006-759388
