Recovery raid 1
RAID 1 recovery is the process of data recovery on an array of two disks, where information is mirrored to ensure reliability and protection against data loss. If one of the disks fails or becomes unavailable, the second disk continues to work and provide access to data.
If you need to restore RAID 1 after a disk failure, follow these steps:
Step 1: Replace the damaged/inaccessible hard drive
The first thing to do is to replace the damaged or unavailable hard disk with a new working instance of the same type and capacity. Make sure the computer is turned off before performing this operation.
Step 2: Connecting a new hard drive
Connect the new (working) HDD to the free SATA port of the controller of your computer or server. Pay attention to the correct connection according to the position of the connector (Primary Master/Slave or Secondary Master/Slave).
Step 3: Turn on the system
Start the computer and go to the system BIOS setup.
Adjust the boot parameters so that the computer boots from the RAID controller.
Step 4: Restoring the array
When the system is turned on, the RAID controller should automatically identify a new hard disk and offer to perform the array rebuilding (restoration) procedure. Agree to this.
The process may take some time, especially if the data volume is large or the HDD write/read speed is limited.
It is important to remember:
1. Do not turn off the power of the computer or server until the recovery process is complete;
2. Regular creation of backup copies is a good practice to protect data in case of possible hardware failure;
3. Check the condition of the other disks of your RAID array after successful rebuilding - sometimes one of the two drives is unstable;
