RAID 1 Failure - Recovering


I have a 3ware 9650SX controller and I have had many 3ware controllers of lesser release. Never once has RAID saved my butt. Right now I have drive 1 reporting Not in Use. I am in the server downloading hosting backups made using Virtuozzo 4 but I don['t think this part matters.

How do I recover from such a failure with losing drive 0? I am so tired of 3ware failures and RAID in general. The motherboards are server boards and have no on-board SATA or even IDE controllers.

I am truly hoping that someone can help me. I am tired of servers going down because in spite of having RAID I end up having to restore the OS by reinstalling it and then recoveing from backups. I am now in a position where the backups are on the failing server.

Drive 0 is responding. It appears that I am in 32-bit mode on a 64-bit Centos 6.2 server.

I am begging for help at this point. Someone please help me if you can. I am not a hardware guru and just barely get by.

Some hardware RAID cards don't fail over well if the drive is bad but still responds to commands. Another possibility is that the card itself is bad. You need to find the problem and a working arrangement before making any irreversible changes. The worst thing to do is to jump in and start trying things at random.

Try unplugging the bad drive and just booting from the remaining drive. Once you have a working system replace the bad drive with a new one and rebuild the RAID.

I worked closely with 3ware on a Saturday -- from his home! He had me up and running in no time.

Thanks for the reply.
