Case 2:
Can't activate attached disk on running vm.
Strange things: when disk is deactivated and vm if powered on i see on host:
[root@ovih01 ~]# rbd showmapped
id pool namespace image snap
device
0 cinder volume-c5a301c7-fc59-400f-8733-61e34c8fadf1 -
/dev/rbd0
Also i can't activate disk with ERROR: disk already attached to vm. Of cause i
didn't see disk from guest os.
