Hi,
I have an ovirt 4.4.3 with 2 clusters, hosted engine and iscsi storage.
First cluster, composed of 2 servers (host1 and host2), is dedicated to the
hosted engine, the second cluster is for vms. Furthermore, there is a SAN
with 3 luns: one for hosted engine storage, one for vms and one unused. My
SAN is built on top of a pacemaker/drbd cluster with 2 nodes with a virtual
ip used as iscsi Portal IP. Starting from today, after a failover of the
iscsi cluster, I'm unable to start the hosted engine. It seems that there
is some problem with storage.
Actually I have only one node (host1) running in the cluster. It seems
there is some lock on lvs, but I'm not sure of this.
Here are some details about the problem:
