Yes, this is what struck me about your situation. Will you be able to find relevant logs regarding multipath configuration, in which we would see when (or even why) the third connection was created on the first node, and only one connection on the second?

Gianluca,

I can see that the workaround you describe here (to complete multipath configuration in CLI) fixes an inconsistency in observed iSCSI sessions. I think it is a shortcoming in oVirt that you had to resort to manual configuration. Could you file a bug about this? Ideally, following the bug template presented to you by Bugzilla, i.e. "Expected: two iSCSI sessions", "Got: one the first node ... one the second node".

Edy, Martin, do you think you could help out here?

Thanks,
Ondra

Ok, this evening I'm going to open a bugzilla for that.
Please keep in mind that on the already configured node (where before node addition there were two connections in place with multipath), actually the node addition generates a third connection, added to the existing two, using "default" as iSCSI interface (clearly seen if I run "iscsiadm -m session -P1") ....
