Default Bug#583870: Acknowledgement (linux-image-2.6.26-2-686: inconsistencies in ext3 file systems)

Hi,

the problem only surfaced when the machine did not come up after an
attempt to reboot (shutdown -r now).
Trying to check the affected file system yields tons of these (almost
2000 lines):


# fsck -p /dev/mapper/uv0-srv
fsck 1.41.3 (12-Oct-2008)
/dev/mapper/uv0-srv contains a file system with errors, check forced.

/dev/mapper/uv0-srv: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
(i.e., without -a or -p options)

it turns out that only one directory was affected. This directory
contains 488984 files. I don't think that having many files in a
directory should be an error, only (possibly) a performance problem.
But in no case should the file system become corrupted, imho.


Kind regards,
