Hello people, in the past Maor Lipchuk (from RH) tried very hard to help me and Uwe but we was unable to converge on the solution.
This was discussed a year ago and on my understanding it still and oVirt bug. As today, if you simple “DuckDuckGo” for “ovirt iscsi multipath not working” the third link points to this bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1474904 <https://bugzilla.redhat.com/show_bug.cgi?id=1474904> Which is the one I’ve mentioned and it’s extremely similar to John Florian case, which was my case too. @John, take a look at the bugzilla link and see if the desired topology match with your case.
