Thanks a lot Karli - restarting vdsmd did the trick!

Well, even a broken clock can be right. Even twice a day:)

@developers
Is this something you have noticed as well? I mean, that sometimes vdsmd needs this manual kick? Where do you start debugging when this issue occurs, restarting the daemon once in a while is just the quickfix, I´d like to solve it once and for all.
Yeah there have been applied multiple fixes in that regard already.

https://github.com/oVirt/vdsm/commit/5b5c58580e20ffaf3ceff7193f4c28cbadd8c42f
and https://github.com/oVirt/vdsm/commit/26bfc74765aed35af6d17cfad1ed8115eef650f1

So it looks like that both of you are using oVirt 3.1, which contains neither of those two fixes. AFAIK only the first one is in oVirt 3.2 and the second one is in oVirt 3.3

Öhm:
ovirt-engine-3.2.2-1.1.43.el6.noarch

And René already stated running 3.2.3
Hmm interesting, but that VDSM version is not 3.2? Did you upgrade your hypervisors?

All systems are as upgraded as they can be, and dc/cluster is running in 3.2-mode. Probably since I´m running dreyou´s repo (and perhaps René as well), the versions may be different from what´s in yours?
Sorry my bad, I messed up the correlation with the versions. I thought 4.10.3 is 3.1 but it is really 3.2.
So this issues are fixed with 3.3 where I would wait with the upgrade until it was finally stabilized.

Yepp yepp, that´s what I was thinking as well. About when would you think 3.3 has stabilized, 3.3.1?

Unfortunately not much I can recommend besides to upgrade at some point. :-(
