The 'get-availability-zone' action will get information about an
availability zone that will contain information about the CRUSH
structure. Specifically 'rack' and 'row'.
When gathering the list of local OSD ids, the charm would consider
the entries under '/var/lib/ceph/osd/ceph-XXX' where 'XXX" was the
OSD id. However, if an entry under that directory isn't mounted,
then the OSD that would represent that entry should be discarded,
as it's no longer active. This patchset thus filters those entries
by looking for them in the mount points.
If the disk being zapped is used by lvm (if it contains the
lvm label and hasn't been pvremove'd) it's safer to simply
bail out of zapping it than attempt teardown through a force
pvremove, because the disk being zapped might be in fact in
use by some LV.
