Description of problem:
I try to umount a volume created at installation time in order to
resize it. When I umount the partition, it seems to work correctly,
buy when I view the /etc/mtab, the entry for the partition is still
This makes other programs that rely on the contents of /etc/mtab fail.
The partition seems to be umounted, because if I try to umount it
again I get a message saying that the partition is not mounted. The
problem resides in the contents of /etc/mtab not been updated.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. umount a lvm partition
2. cat /etc/mtab
Expected Results: I think, the partition should have been deleted
from /etc/mtab, or if it has been impossible to umount it, then
umount should have returned an error.

Here you have a more detailed description of my lvm configuration.
I think the problem begins if you try to umount the / partition.
when doing so, the system does not report any error, but all
subsequent tries to umount a partition leaves /etc/mtab unchanged.
If you umount the root partition the file /etc/mtab is unavailable for arbitrary
command and the mount doesn't update /etc/mtab of course. Please, can you step
by step describe how reproduce your problem?
