Hello,
I was trying to improve iSCSI performance by increasing number of simultaneous connections to iSCSI target. Please note it's not about iSCSI multipathing. It's about using multiple connections over the same network/path to utilise network interface bonding.
/etc/iscsi/iscsid.conf has an option where I can set number of session by default - node.session.nr_sessions. I've found that multiple sessions work well, but VDSM doesn't disconnect all established sessions. Maintenance mode disconnects the first connected session only. Other sessions remain connected.
I've filed a bug https://bugzilla.redhat.com/show_bug.cgi?id=1322933 with a patch to fix the issue.
Thanks Pavel! Can you post your patch to gerrit? See http://www.ovirt.org/develop/dev-process/working-with-gerrit/ If you need help you can try #vdsm at freenode. Cheers, Nir
