Raid 1 recovery
RAID 1 (Redundant Array of Independent Disks) is a method of organizing data storage on several hard disks in order to ensure fault tolerance and increase system reliability. In RAID 1, data is recorded simultaneously on two or more disks, which allows you to restore information if one of them fails.
If one of the disks in the RAID 1 array fails, the following steps should be performed to restore it:
Step 1: Replacing the damaged disk
It is necessary to replace the physical device-inaccessible/non-functioning hard disk with a new working equivalent of the same size and model. It is recommended to use the same type of connection interface to the motherboard (SATA or SAS).
Step 2: Initialize the new disk
Connect the new spare HDD to the free SATA/SAS controller ports of your server or computer. When booting the operating system, check the availability of this device through BIOS / UEFI.
Then use RAID software (RAID controller or firmware) to initialize the new disk as part of the array. In this case, the data from the working hard disk will be copied to the replacement hard disk.
Step 3: Rebuilding (restoration)
After successful initialization of the new spare HDD, the RAID controller will automatically start the process of rebuilding - copying data from the working/working device-donor party to the recently connected drive.
It is important to note that the reconstruction time depends on the amount of information stored on the remaining functional hard disk (working). The factory size can be reached after several minutes to several hours or more.
