Help needed - RAID5 recovery from Power-fail

I wonder if you could help a Raid Newbie with a problem I had a power fail, and now I can't access my RAID array. It has been working fine for months until I lost power... Being a fool, I don't have a full backup, so I really need to get this data back. I run FC4 (64bit). I have an array of two d

Cheap Motherboards and Linux RAID

If you happen to be unfortunate enough to have also purchased a cheap ASUS K8N VM with the Nforce410 chipset in order to get the software RAID (or anything for that matter) to work you have to disable APIC . This means APIC modules must not be loaded. Joe Olstad, Solid Computing Corp Edmonton,

RAID rebuild I/O bandwidth

Hi Folks, I am doing some research on calculating I/O performance of a raid array. I want to test the RAID rebuild. Can anyone specify what raid rebuild I/O bandwidth is? How should I set 10MB/sec of rebuild I/O bandwidth? How should I measure time to rebuild a disk? Thanks in advance, Thanks,
