Re: [ovirt-users] Hosts temporarily in "Non Operational" state after upgrade
Answers inline below...
From: Michal Skrivanek [mailto:michal.skrivanek@redhat.com]
what exactly did you do in the UI?
Clicked on the node, and in the bottom pane, clicked on the "Upgrade"
link showing there (the nodes also had an icon indicating that updates were available)
so..it was not in Maintenance when you run the update?
You should avoid doing that as an update to any package may interfere with running
guests.
E.g. a qemu rpm update can (and likely will) simply kill all your VMs, I suppose
similarly for Gluster before updating anything
the volumes should be in some kind of maintenance mode as well
No, the "Upgrade" link once clicked migrates any running VM off the target node
onto another node, then sets the target node into Maintenance mode, and then performs the
updates. Once the updates are completed successfully, it re-activates the node and makes
it available again. On the second and third nodes this coming out of Maintenance process
experienced a problem with mounting the Gluster storage so it seems, and had the problems
I'd indicated.
