[xen-tools-discuss] Unmountable devices

[Bubba Sour]

Hi!

If a xen-create-image processes has been aborted for some reason, it
happens that I have /tmp/<ID> mounts where the LV is mounted, and the
device seems busy and unmountable. A reboot seem to help, but I wish there
are other ways solving this.

mount on dom0
/dev/mapper/myvg-test--disk on /tmp/ermebNGZVj type ext3 (rw)
/proc on /tmp/ermebNGZVj/proc type none (rw,bind)
devpts on /tmp/ermebNGZVj/dev/pts type devpts (rw)

# umount /tmp/ermebNGZVj/
umount: /tmp/ermebNGZVj: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))

# lsof /tmp/ermebNGZVj/
#

# fuser -a -u -v /tmp/ermebNGZVj/proc/
                     USER        PID ACCESS COMMAND
/tmp/ermebNGZVj/proc/:
                     root     kernel mount (root)/proc

# fuser -a -u -v /tmp/ermebNGZVj/dev/pts/
                     USER        PID ACCESS COMMAND
/tmp/ermebNGZVj/dev/pts/:
                     root     kernel mount (root)/dev/pts

# fuser -a -u -v /tmp/ermebNGZVj
                     USER        PID ACCESS COMMAND
/tmp/ermebNGZVj:     root     kernel mount (root)/tmp/ermebNGZVj

and the LV is of course not removable.

Any ideas on how to fix this? Thanks!
