Hi Alexander, 
I tested the process of persisting file system changes but it all worked as expected. Looking at the log snippet you sent, the only thing that seems off is the very first line: Completed creation of a snapshot for the volume 'None', snap id: 'snap-6f0b211d' - volume should not be None there. Actually, it's incredible that it would be None because a volume must exist in order to create a snapshot... Do you have more content from that log?

In the mean time, I added more safeguards if this happens again: https://github.com/galaxyproject/cloudman/commit/337ecb95a04788e540d60be37b4f4f817257b24f
