root fs error on boot

[daytooner]

When I boot, I always get these messages:

[    5.916703] EXT4-fs warning (device dm-1): ext4_clear_journal_err:4401: Filesystem error recorded from previous mount: IO failure
[    5.916775] EXT4-fs warning (device dm-1): ext4_clear_journal_err:4402: Marking fs in need of filesystem check.

The first time I saw this, the boot dropped me to a "[repair]" shell prompt, and I could run fsck on the partition to fix the problems. But now it always says the file system was last mounted with errors. (And yes, the system shuts down cleanly.) There doesn't seem to be any problems: everything runs fine, and I get no errors in syslog.

So, is there really a problem with this partition? If not, how do I get it to stop running fsck every boot?

I know that I can boot up from the install image and run in rescue mode. But, this was a network install, and I don't have a server running with the install image. I also don't know if I would need that to fix this. I was hoping I wouldn't have to.

FWIW:

[root@Elmer ken]# uname -r
3.5.2-1.fc17.x86_64

Any help greatly appreciated.

TIA

Try to boot from a LiveCD and run e2fsck manually.
