Recovery raid 10 from 4 disks
Restoring RAID 10 from four drives can be a fairly simple procedure if one of the drives has failed. In this case, you will need to replace the damaged disk and rebuild the array.
Below is a step-by-step algorithm for restoring RAID 10:
1. Determine which particular disk does not work or has errors.
2. Purchase a new hard disk of the same size and model as the other working devices.
3. Turn off the computer or server with a malfunction of the RAID 10 array.
4. Replace the non-working/failing hard drive with a new one of the same type (size) without powering the system (in line).
5. Turn on your computer / server after successfully replacing all failed HDD drives
6. Start the software of the BIOS contract of the machine coding of the motherboard connector SATA/SAS/PATA/Molex/FDD/HDMI/DVI/VGA/LAN/Wi-Fi/BT/GSM/CDMA/NFC/UWB/ZigBee/IrDA/Radio /Audio/JTAG/CPU/APU/GPGPU/TDP/IPMI/KVM/iLO/LOM/BMC/SMBus/I²C/PWM/FAN/Cooler/Voltage/Memory/RAM/HDD/SSD/Optical Drive/Card Reader/Audio Card/GPU/NIC/Wi-Fi Adapter
7. Enter the BIOS and make sure that the new disk is recognized by the system.
8. Run the program for rebuilding the RAID 10 array (usually this is done through the interface of the BIOS contract of the machine coding of the motherboard connector SATA/SAS/PATA/Molex/FDD/HDMI/DVI/VGA/LAN/Wi-Fi/BT/GSM/CDMA /NFC/UWB/ZigBee/IrDA/Radio/Audio/JTAG/CPU/APU/GPGPU/TDP/IPMI/KVM/iLO/LOM/BMC/SMBus/I²C/PWM/FAN/Cooler/Voltage/Memory/RAM/HDD / SSD / Optical Drive / Card Reader / Audio Card)
9. Wait for the RAID 10 array reconstruction process to complete.
It is important to note that the recovery time may take some time, especially if the volume of data on your array is large or you use old hard drives with low performance
