Hello:
Since I upgraded to 4.0 I have troubles with the storage of my oVirt setup. I have 2 IBM 3512 arrays connected to 8 ovirt hosts through FC. When a host is rebooted or when a new port get online in the FC switchs although the port isn't connected to storage or oVirt hosts; oVirt reports I/O problems and pause some vm's. I have to manually resume the vm's. It seem that any change (even non disruptive changes) to FC switchs and HBAs causes that ovirt detects I/O problems.
How I can debug this issue. How can I know if It is related to vdsm/ovirt, mulitpathd..?
We need to inspect engine log, vdsm log, supervdsm.log, sanlock log, and /var/log/messages. If ovirt detect io problems it is probably because they are problems. Can you file a bug and attach the logs? Nir
