We have a new 4.1.1 cluster up and running with OVS switches and an iSCSI hosted_storage
and VM data domain (same target, different LUN's). Everything works fine, and I can
configure iscsid and multipathd outside of the oVirt engine to ensure redundancy with our
iSCSI device. However, if I try to configure iSCSI Multipathing within the engine, all of
the hosts get stuck in the "Connecting" status and the Data Center and Storage
Domains go down. The hosted engine, however, continues to work just fine.
Before I provide excerpts from our logs and more details on what we're seeing, it
would be helpful to understand better what the advantages are of configuring iSCSI Bonds
within the oVirt engine. Is this mainly a feature for oVirt users that don't have
experience configuring and managing iscsid and multipathd directly? Or, is it important
to actually setup iSCSI Bonds within the engine instead of directly in the underlying OS?
Any advice or links to documentation I've overlooked would be greatly appreciated.
Many thanks,
Devin
