Hi Andreas,

I reproduced it and I'm pretty sure I fixed it. PVE is kind of special...
It calls functions over and over again. Then they invented caches. I
used it wrong in one location. I cached the actual storage pool name
(which I should not have), so all drbd storages reported the same size.
Which one most likely depended on Perl dict ordering. So it selected one
of the storages randomly and reported this size for all. That is why it
flipped between the values of the two pools.

If you an, please test:

Unrelated, I need to check if we handle auto-quorum correctly, but I
would release a new version early next week. An OK from you side would
be cool.

Thanks, rck
