Hi,

I have a centos 4.2 server setup and running as a zimbra email server.

It has 2 18.4Gig SCSI hard drives setup in software raid 1 for mirroring.

I had tested the unit before production and found that if I disconnected
one of the drives the other wouldn't boot

I search and found that I had to modify the boot (I don't remember
exactly at the moment)

After testing I am sure it worked.

On the weekend the power went out and turns out one drive had failed and
the server wouldn't boot from the other drive.

I am not sure at what point the other drive failed could be days could
be weeks ago.

What is the proper way to get the system running again?

I can fix the failed drive.  (damaged pin).  When I get it running again
will the info on the drive that won't boot be mirror back to the other
drive?

I am sure the drive that won't boot due to grub and raid is the most
current.

Thanks for any help

Mace
