My PVE (w ZFS) was re-installed about 2 weeks ago. I tried to do a backup of any of my VMs today and it caused both the PVE SSH and web to stop, i.e. can't connect to them anymore. My only option was to press the hardware reset button and I don't see any backup file after getting into the web UI again.
1. On 1 of the VMs of interest (32G disk), this stopping always happens when the backup reaches 27%, so I went to check my diskspace, which shows another 50G still available. I don't think I'm out of space. Then I ran it from the CLI and gets stuck at `resuming VM again` and at this point, the web UI stops, a SSH that is already running continues to work, but no new connections can be made
2. My ZFS pool looks good,
This is the 2nd time I'm unable to take backups (1st was due to a corrupted ZFS pool), and makes one feel really helpless to see my VMs run but have no way of taking backups.
Any idea how to troubleshoot this? Thank you.
