I have a Self-hosted Engine running on iSCSI as well as couple of Storage
domains using iSCSI, both the SE and those Storage Domains uses the same target
portals (two).
I can see the iSCSI sessions and multipath working well from the Host point of
view.
Yesterday after doing a restart for the “ovirt-engine” all the hosts besides
the one that runs the SE and the SPM went into “Unassigned” mode with an error
stating the ovirt-engine can’t communicate with the hosts.
Network wise, everything is good, I can reach all the ports, all the network is
well configured, so I ruled this.
Looking at the VDSM logs on those “Unassigned” hosts it looks like the VDSM
can’t find the Storage Pool.
(vmrecovery) [vdsm.api] START getConnectedStoragePoolsList(options=None)
from=internal, task_id=217ec32b-591c-4376-8dc0-8d62200557ee (api:48)
(vmrecovery) [vdsm.api] FINISH getConnectedStoragePoolsList return={'poollist':
[]} from=internal, task_id=217ec32b-591c-4376-8dc0-8d62200557ee (api:54)
(vmrecovery) [vds] recovery: waiting for storage pool to go up (clientIF:723)
If I look at the VDSM logs on the host where the SE and SPM is running, no
issues there and the node appears up (green) in the ovirt-engine UI.
I managed to set the hosted-engine to maintenance, shut it down and then start
it again on another Host, when it starts on that Host, the host goes “green”
and if the SPM stays on the previous host, I have two hosts working and the
rest remains “Unassigned”.
All the “ovirt-ha-agent”/”ovirt-ha-broker” services seems ok, I restarted them,
I also tried to restart the VDSM on the hosts with no luck.
I have the VMs still running, I did shutdown one host (even used the “SSH
restart” from the WebUI) to see if that helps, it came back and still went into
“Unassigned”.
It seems like the hosts can’t see the Storage pool.
Where should I start to troubleshoot this?
Thanks
