Recently, my system crashed and I had to boot from a CD in order to repair the filesystem. It appeared that the filesystem was successfully repaired, but since then I always get "/dev/sda2 contains a filesystem with errors, check forced" every time I boot. The check never finds anything wrong, and the system boots successfully. How can I convince my system that it doesn't need to run the check on every boot?

Did you change your /etc/fstab when repairing your system?
Depending on the values of the last two numbers in the line for /dev/sda2 a fscheck is forced on startup I think.
(If the last value is set to zero there is no automatic check on boot)

Alex.

No, I didn't change /etc/fstab. Even if it checks the filesystem every time, it shouldn't be claiming there are errors every time. Anyway, the fstab entry is:
Code:
/dev/sda2               /               ext3            noatime         0 1

Think you may need to do an offline fsck. Boot from a sysrescuecd and check the filesystem.

Mm yeah, you are right.

Next to trying an offline scan as suggested, you might also try to use smartctl
Use
Code:
smartctl -h
to see all option, it can give more information about the disk itself and includes some test (smartctl --test /dev/sda) to check if your disk is alright.

I did that once already when I repaired the file system, but I suppose it won't hurt to try again.

I ran fsck from a live cd, and it reported that the filesystem was clean. But when I boot from disk, I still get "/dev/sda2 contains a filesystem with errors, check forced".

I tried mounting and then unmounting the filesystem from the livecd. fsck reports the filesystem as clean beforehand and as having errors afterward. The dmesg contains:
Code:

EXT3-fs (sda2): warning: ext3_clear_journal_err: Filesystem error recorded from previous mount: IO failure
EXT3-fs (sda2): warning: ext3_clear_journal_err: Marking fs in need of filesystem check.
EXT3-fs (sda2): warning: mounting fs with errors, running e2fsck is recommended


So it appears that there is something weird going on with the journal that fsck doesn't detect, but mount does.

Maybe your drive is going bad. Have you run smartctl (from smartmontools) against it?

You might try removing the journal and adding it back.

That fixed the problem, thanks.
