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
Okay I have the damaged drive fixed and running. It looks like it failed april 6th. So everything has been running on the other drive. But I can't get the other drive to boot. How can if fix it so it will boot? When I hooked them together after fixing the primary drive it still wouldn't boot. If I unplug the mirror drive that won't boot It will boot from the drive I fixed. So I need to get the secondary mirror that is current to boot and then mirror it to the fixed drive (or soon to have replacement drive) I am desperate to get this going.
