Hello,

What can cause an "EXT2-fs warning: maximal mount count reached, running
e2fsck is recommended" ?

I mounted "mount /dev/fd0 /mnt/floppy" and,
unmounted "umount /mnt/floppy"
repeatedly as I was tranferring files from one computer to another.

If a floppy was normally unmounted each time after mounting it, why should
the "mount count" keep increasing ?

The problem where this occured is on "RedHat 7.1" and kernel 2.4.2

Thanks,
Tony

Exceeding the filesystem's maximum mount count.

Yep, that will do it.

Because it is incremented whenever the filesystem is mounted, and it
*isn't* decremented when the filesystem is unmounted.

The purpose of the maximum mount count setting is to ensure that the
filesystem gets checked occasionally. There is also a maximum check
interval, which operates according to elapsed time rather than the
total number of mount operations.

If you want to avoid this warning, use "tune2fs -c -1 /dev/fd0";
similarly, use "tune2fs -i 0 /dev/fd0" to disable the maximum check
interval. In either case, tune2fs should only be run on unmounted
filesystems.

Strange ! I wrongly assumed that there'd be a MOD_DEC_COUNT whenever the
floppy is umounted.
