------- Comment #5 from folkert@...heusden.com  2009-01-05 12:11 -------
After that I tried creating a file in each filesystem. When I hit /var I got
the following dmesg error:

[  335.006864] journal_bmap: journal block not found at offset 524 on dm-0
[  335.006927] Aborting journal on device dm-0.
[  353.624981] ext3_abort called.
[  353.625058] EXT3-fs error (device dm-0): ext3_journal_start_sb: Detected
aborted journal
[  353.625211] Remounting filesystem read-only

After that no file was accessible. E.g.:
debian:/home/folkert# umount /var
bash: /bin/umount: cannot execute binary file
