Routines responsible for polling of in-progress pvmove, snapshot merge
or mirror conversion each used custom lookup functions to find vg and
lv involved in polling.
Especially pvmove used pvname to lookup pvmove in-progress. The future
lvmpolld will poll each operation by vg/lv name (internally by lvid).
Also there're plans to make pvmove able to move non-overlaping ranges
of extents instead of single PVs as of now. This would also require
to identify the opertion in different manner.
The poll_operation_id structure together with daemon_parms structure they
identify unambiguously the polling task.
Support "wait before testing" using '+' in pvmove and lvconvert
interval. Doing so overrides the new default of sleeping after checking
the LV's progress.
Sleeping before checking progress can lead to extraneous polldaemons
being left running. These polldaemons would have otherwise exited had
they checked before sleeping. Checking progress before sleeping helps
workaround the subtly unreliable nature of "finished" state checking
in _percent_run.
Update test/t-mirror-names.sh to use '+' when providing its lvconvert
interval.
When mirror convert polling is started (mainly as backgound process,
in lvchange -a y or in lvconvert itself) it tries to read VG
and LV identified by its name.
Unfortunatelly, the VG can have already different LV under the same name,
and various more or less funny things can happen (note that
_finish_lvconvert_mirror suspends the volume for example).
(the typical example is our testing script which continuously recreates
LVs under the same name in the same VG.)
This patch adds optional uuid parameter which helps to properly
select the monitoring object. For lvconvert polling it is set to LV UUID
and both _get_lvconvert_vg and _get_lvconvert_lv uses it to read proper VG/LV.
(In the pvmove case it is NULL, here we poll for physical volume name).
