Last night my server encounter "Read-only file system" error.
So then I ran "fsck -Af -M" to trying to repair but no use, these are output:
fsck 1.39 (29-May-2006) e2fsck 1.39 (29-May-2006) /: recovering journal fsck.ext3: Bad magic number in super-block while trying to re-open / e2fsck: io manager magic bad!
After I reboot the server, I can't even recover the filesystem anymore and must reinstall the OS. My / was RAID 1 and ext3 formated. Did that fsck command cause my filesystem corrupted? or it has been corrupted before I run fsck?
