Thanx for your replies.
And sorry, i havent seen your first reply between my last posts with the link to your existing Thread.
So, i think this is some kind of a bigger thing.
Will handle with care, but i have to leave for today.
Maybe i have time to test the snapshot and revert workarounds on the weekend.
But these are all production VMs.
Have to coordinate.
I have 2 NFS-SRs in the Pool.
Will try to migrate VMs from one to the other and see if this helps.
Kind Regards and thx again
Alex
