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)

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.
ok, thanks for clarification, you got me scared:)
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.
it might be a question for gluster guys, it might be that the maintenance process is a bit
different there
Sahina, can you check/comment that?
Thanks,
michal
