I Keep getting "EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended" on my Compact Flash based FS

Hi all,

I'm working on a ppc based embedded system, and am using a compact flash based filesystem. When I created the filesystem I ran: tune2fs -c 1 My /etc/fstab looks like this: # rootfs / rootfs rw 0 1 proc /proc proc defaults 0 0 sysfs /sys sysfs defaults 0 0 devpts /dev/pts devpts defaults 0 0 tmpfs /dev/shm tmpfs rw 0 0

But for some reason I keep getting: "EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended" and my filesystem doesn't auto-run the fsck (e2fsck) utiliy - WHY? WHAT AM I DOING WRONG?

Thanks in advance, Lenny.

How should the filesystem itself do that?

When you formatted the CF the mke2fs program it told you it would require a check after XX mounts. You reached (or exceeded ) that limit.

You need to do a 'tune2fs -c 0' (I think) on the CF after you do a mke2fs, to turn off checking.

OK, I guess I understand the problem... But, alas, how can I force the auto-check to run every XXX mounts? The warning is received before the root fs is mounted - so there must be a way: "EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended VFS: Mounted root (ext2 filesystem). Freeing unused kernel memory: 132k init"

Thanks again, Itamar.

shutdown -F is supposed to force fsck on the next reboot.

Run always (every boot) e2fsck on this partition. If the filesystem is clean it returns immediately, if not it will check and repair it. After XXX mounts (using the tune2fs tool to setup this count) it forces a whole check automatically, even if the filesystem is was marked clean. Don't forget to mount the rootfilesystem as *read only* from kernel's side, to run e2fsck on it. After e2fsck has done its job, remount "/" with write permissions.

Not "before", this warning occures while mounting.

first of all, the message comes from this entry on fstab, rootfs / rootfs rw 0 1 your root is a rootfs and not an ext2/ext3 thats why fsck -a fails because it calls for fsck.rootfs instead of fsck.ext2 (fsck is a frontend for the 'fsck.fs' backends). secondly, shutdown -F normally creates an empty file /.autofsck and in most rcS scripts checks for the existence of this file before calling fsck -a. third, mount knows that the root is an ext2 so it complains about dirty filesystems from the fstab entry (some distro makes mount also calls fsck without repairing). fourth, i dont think using tune2fs to check every mount is appropriate, at least give it a larger range, say 1000 mounts. the last field on fstab ('1') already checks it for every mount. i don't know if its relevant, but isnt compact-flash has some limits on how many writes to an area? i mean e2fsck would write the last fsck stamp to it.

well, hope this helps ys
