[plug] Urgent RAID Help needed

[Mark Nold]

Thanks heaps Ben, Adrian and Simon...

Bit of a disaster, but managed to recover the disk, so it saved going to
last nights backup tape and reconfiguring/recompiling some stuff (we dont
backup the whole system just user data).

So thanks a lot.

I ended up chucking in another disk, installed latest RH (so we get a quick
upgrade) and mounted the previously RAID member as an ext2 disk and copied
all my data dirs over to the new disk. Now i'm just checking cron jobs etc
and it all should be sweat.




Thanks,

mn

Do you really want to boot?

If it were me Id use tomsrtbt or something similar to rebuild to raid set
onto the replaced disk and only reboot when I was sure everything was aok
