Hi Groete, If the problem still persists, can you please increase the log level to debug on the KVM host, recreate the issue and share if any issues on the host agent logs?

I tried creating new volume snapshot again. And once again, the process has gone stuck. All I's up and running, NFS is also active. Maybe this is a bug for KVM?

And this caused the snap process to hung and also caused the mount error below. I had to comment the lines in /etc/exports, reload deamon and only then could I start NFS again. I then uncomment lines in /etc/exports and deamon reload again and now storage was back up and now host can connect to CM again. Not sure why NFS random dropped for no reason.
