2.6.0-test9 / EXT3-fs warning...ext3_unlink: Deleting nonexistent file

[Florian Lohoff]

Hi,
i seem to have experienced some ext3 inconsistencys - After some reboots
today i was wondering why cron wasnt running and discovered that
starting cron failed because /var/run/crond.pid could not be written.
ls did not show and file under that name. touch showed i/o error on that
file although other file in that directory could be touched.

When i tried to rm crond.pid this showed up:

EXT3-fs warning (device hda8): ext3_unlink: Deleting nonexistent file (107669), 0

After that i could touch the file again and crond did not refuse to start anymore.
I havent experienced ANY ide failures on this disk so far

Some more debugging output:
