Question, does umount still unmount "one instance" of the mount? This
is the behavior under Red Hat Enterprise 3 (2.4 kernel) which also
doesn't complain. The application I QA hasn't managed to get confused
enough under RHEL4 (we start supporting RHEL4 under our next release) to
mount one of our mount points multiple times so I don't have a data
point for RHEL4 (2.6 kernel).
Under FC4 (kernel 2.6.14-1.1644), umount removes no mounts at all if there are
multiple mounts of the same mount point.
Under RHEL3, I just keep issuing umounts for the mount point until I get
rid of all of them. Would this work for your situation? Any idea when
this "feature" got added to mount/umount?
The only thing that worked for removing one of the duplicate mount points was
umount -f (as root).
I wrapped a code snippet posted earlier in this thread into a function that I
then placed in my .bashrc.
mount_if_not_mounted() {
MOUNT='/bin/mount'
MOUNTPOINT='/mount/point'
if [ "`$MOUNT | grep "$MOUNTPOINT"`" = "" ] ; then
$MOUNT $1
fi
}
What is the expected value of $1?
Minor modification
mount_if_not_mounted() {
MOUNT='/bin/mount'
MOUNTPOINT=$1
if [ "`$MOUNT | grep "$MOUNTPOINT"`" = "" ] ; then
$MOUNT $MOUNTPOINT
fi
}
mount_if_not_mounted "/mnt/samba/share";
In this case there's a parameter being supplied to the funtion which is
used to define the mount point...
That works wonderfully when invoked from .bash_profile as
mount_if_not_mounted /mount/point
