Public bug reported:
When the mount phase of pbuilder fails, pbuilder umounts directories
that have already been successfully mounted (/usr/lib/pbuilder/pbuilder-
modules lines 273 - 291) but it uses the device name (name of the
directory being bind mounted) instead of the name of the mount point.
If the directory is bind-mounted several times in others, unrelated,
chroots it tries to unmount all of them.
For example (full log attached) on the log below note that PIDs in
cow.<PID> are different:
I: umounting /var/lib/jenkins/cu2d
umount: /var/cache/pbuilder/build/cow.15281/var/lib/jenkins/cu2d: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
umount: /var/cache/pbuilder/build/cow.1195/var/lib/jenkins/cu2d: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
umount: /var/cache/pbuilder/build/cow.1197/var/lib/jenkins/cu2d: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
umount: /var/cache/pbuilder/build/cow.1739/var/lib/jenkins/cu2d: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
umount: /var/cache/pbuilder/build/cow.59368/var/lib/jenkins/cu2d: not mounted
umount: /var/cache/pbuilder/build/cow.53454/var/lib/jenkins/cu2d: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
umount: /var/cache/pbuilder/build/cow.36950/var/lib/jenkins/cu2d: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
umount: /var/cache/pbuilder/build/cow.19691/var/lib/jenkins/cu2d: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
line 278 of /usr/lib/pbuilder/pbuilder-modules could use the full path of the mount point:
mounted[${#mounted[@]}]="$BUILDPLACE/$mnt"
instead of $mnt only.
