Lightbulb Repair Filesystem after deleting RAID


Playing with the Box, I deleted a Raid-0 partition intentionally, saved it, and reboot drops me to (Repair Filesystem#) prompt. I notice during boot-up that the box didn't find /dev/md0, which is expected.

So what's the recovery procedure, since I can't edit #/etc/fstab, permission denied.

#fdisk -l
shows all other partitions.

Not much familiar with fsck/e2fsck, yet like to give it a try.
Anyone who'd shed some light?

Thanks, all Linux People.

This should take care of not being able to modify /etc/fstab:
Code:
mount -o remount,rw /
As for the RAID0 recovery, I guess it really depends on how you deleted it and what details you have about its construction, but I suspect, while I've never attempted this myself, there is a facility within mdadm to allow you to lay down the information again if you have all the specifics.

Hope this helps.

EDIT: If all you did was delete the partition, it may be as simple as recreating the partition with the same start and end cylinder and setting the partition type to: fd Linux raid auto

Thanks, got back to the prompt using the command you mentioned. Nope, didn't keep any of the specifics just deleted from #fdisk /dev/sda, I guess 'mdadm' or 'fd Linux raid auto', gives some more insight, which I hope to check later on. But thanks again. for now.

#mount -o remount,rw /

Thanks, all Linux People.
