--- Comment #2 from nchilaka <nchilaka at redhat.com> ---
On a 2 node cluster, when we do a restart of volume, the tier deamon shows as
in progress or running , when we issue a vol status, but the tier rebalancer
deamon which is supposed to restart on both nodes, doesnt restart on localnode.
It always fails to restart on localhost, but triggers successfully on the other
node.
Hence marking as failed
