Recover from dead hard drive (RAID 1)

Hi,

I have a server running four hard drives:
System RAID 1: 2 x 20GB IDE
Storage RAID 1: 2 X 500GB SATA

I am in the process of creating a disaster recovery plan. Say if one of the 20GB drives were to fail I would like to have some instructions on how to configure a new drive to replace the dead drive.

System configuration:

OS: Centos 5
CPU AMD Athlon 3500+
RAM 1.0GB
HDD hard drives running software raid configuration
2 x 20GB IDE system
2 x 500GB SATA storage

Turn off the system.
Replace the failed hard drives with new hard drives that are of equal or greater capacity.
If the raid is already set recovery automatically, the recovery process will start automatically when turn on the system.
If the raid recovery is not set up yet, when prompted during system startup, press Ctrl and i (or whatever your raid card) at the same time to enter the raid configuration, check there see if recovery option is set.

Hi,

This is software raid configured by the OS. There is no hardware raid.

So lets say I remove a disk, my system should still boot?
Correct.

If your initial ram disk has the drivers for software RAID (which it must do already because the system is currently booting off a software RAID1 partition) you should be fine.
