After a long time, I hit the wall. I upgraded my server from Fedora Core 9 to 10 through yum. The first 2 days it worked happily but the 3rd day I started getting the feeling of being doomed. Bad Magic Block started haunting me and due to several services being failed, I had to restart the server. That was the last time I saw it alive.

During boot, my 34 LVM partitions are active but its not able to mount /dev/root. I did the checked the grub and its fine. I tried rescue CD but still can't utilize most of the lvm, vgscan, vgchange commands as it gives me same 'bad magic block' error. My /proc/partition and /sys/block shows me that only 3 out of 5 HDD are active.

The question is, anybody having idea as to how to resurrect the OS?

Are your server on hardware RAID ? Please check

@ganesh

I'm running soft raid. The /proc/mdstat don't show much, I don't want to screw the whole system by running a wrong/unsuccessful mdadm command.

Btw, is there a way to run ssh services in rescue mode so I can give access to outside for solving problems.
