I updated some Ubuntu 8.04 packages earlier today using the update manager (I don't know which ones; is there a log anywhere?). My /home partition now cannot be mounted.
On startup, there is an error displayed. It looks something like this (since I only have command line access on my laptop, I am having to write the details up on my wife's laptop):
* A file system check failed
A log is being saved in /var/log/fsck/checkfs if that location is writable. Please repair the filesystem manually.
The contents of /var/log/fsck/checkfs is:
fsck 1.40.8 (13-Mar-2008)
fsck.ext3: Filesystem revision too high while trying to open /dev/sda6. The filesystem revision is apparently too high for this version of e2fsck. (Or the filesystem superblock is corrupt).
The superblock could not be read or does not describe a correct ext2 filesystem. If thee device is valid and it really contains an ext2 filesystem (not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
fsck died with exit status 8
According to blkid, /dev/sda6 has TYPE="ext4". Does this mean my partition has been updated from ext3 to ext4? If so, why and what do I do to fix it so that /dev/sda6 can be mounted again?
