RAID5 array hdd offline how to recover

In a RAID5 array, which is usually composed of multiple hard disks, sometimes a sudden power outage causes multiple hard drives to be taken offline, the entire RAID is offline, and the disk array may not recognize the hard drive, which is a common condition. So how do you recover from a disk array failure when one or more hard drives are encountered offline? Here are some ways to introduce you.

First we have a physical failure by checking if a RAID disk array is a disk, and if one of the disks fails, we can fix it first. Then synchronize all the failed disk data to the secure storage media. Analyze all hard disk images for the current full backup, determine the original structural parameters of the failed raid, and determine the offline status of each hard disk in the failed raid. The RAID data is built in the read-only environment based on the analysis of the raid parameters and the offline hard disk, and the basic logical check of the built virtual raid is made, and the complete image of the raid production is determined after the file system structure is correct. This will enable the RAID5 array hard drive to return to normal. However, the above practice must be done by a professional data recovery company in a specific environment, non-professionals should not blindly operate. In the case of RAID5 display hard drive offline resulting in data loss, it should be the first time to consult a professional data recovery company for recovery.
