which precise vdsm.rpm is this? (In reply to Dan Kenigsberg from comment #1) > which precise vdsm.rpm is this? Version : 4.20.0 Release : 38.git59c645a.fc24 From repo : ovirt-master-snapshot I assume you meant network cable? wasn't sure about the impact here? is vdsm down afterwards and not coming up? thanks. (In reply to Moran Goldboim from comment #3) > I assume you meant network cable? Yes :) > wasn't sure about the impact here? is vdsm down afterwards and not coming up? Right, it doesn't come up I can't reproduce the problem (my host's network is only virtual after all) but I understand it can happen under certain circumstances and I believe the posted patch fixes it. Arik, could you please verify the patch (http://gerrit.ovirt.org/69555) whether it fixes the problem? (In reply to Milan Zamazal from comment #6) > Arik, could you please verify the patch (http://gerrit.ovirt.org/69555) > whether it fixes the problem? Yes, done. Verified with rhevm-4.1.0.2-0.2.el7 and host: vdsm-4.19.2-2.el7ev.x86_64. host is nested and I was unplugging the virtual cable, so I hope this is enough, but don't see reason why behaviour should be different. After plugging back the network, host returned back to state 'up' and the error attached in the description doesn't appear. |
