Do you perchance have a RAID implemented on your server?

I had this happen once when I "tested" my raid by removing a drive. Apparently I did not issue to the proper commands to put it in a failed and degraded state prior to removing the disk. I attempted to fix it with fsck but only made the problem worse. Thankfully since I was using a raid 1 (mirrored) the answer was to wipe the one disk and tell it to rebuild the array. Initially it declared the disk as a spare, but once it copied the data over, it was fully functional again.
