Jonathan Earl Brassow 51e294c501 Fix for bug 612291: dm devices of split off mirror images are not removed 
DM devices were not handled properly on nodes in a cluster that were not
where the splitmirrors command was issued.  This was happening because
suspend_lv/resume_lv were being used in a place where activate_lv should
have been used.

When the suspend/resume are issued on (effectively) new LVs, their
'resource' (UUID) is not located in the lv_hash.  Thus, both operations
turn into no-ops.  You can see this from the output of clvmd from one
of the remote nodes:
<snip>
do_suspend_lv, lock not already held
<snip>
do_resume_lv, lock not already held

'activate_lv' enjoins the other nodes in the cluster to process the lock
and activate the new LV.  clvmd output from remote node as follows:
do_lock_lv: resource 'zMseY7CBuO3Ty09vXlplPAHzD0Y0CovjrTdv0R1VcwggMwPdYhutHErRcwm5Nd2S', cmd = 0x19 LCK_LV_ACTIVATE (READ|LV|NONBLOCK), flags = 0x84 (DMEVENTD_MONITOR ), memlock = 1
sync_lock: 'zMseY7CBuO3Ty09vXlplPAHzD0Y0CovjrTdv0R1VcwggMwPdYhutHErRcwm5Nd2S' mode:1 flags=1
sync_lock: returning lkid 27b0001
