[Madhu-1]

Kind of issue

Bug

Observed behavior

after node delete from heketi, the volumes present in the heketi is having backup-volfile-servers as removed node IP

Expected/desired behavior

once the node is deleted from heketi, heketi should refresh volume info as it should not point out to deleted node IP

Details on how to reproduce (minimal and precise)

1)load topology in heketi (it has 3 nodes)
2)create 4 volumes
3)add a new node to heketi
4)disable one old node in heketi
5)remove the same node
6)remove devices
7)delete the node from heketi
8)check volume info on old volumes
