Hi Proxmoxers,
One of my proxmox box got strange behaviour under a Normal installation with ZFS.
On my Debian Guest VM I Got an "I/O error" after one of our IT Member tried to backup the VM.
Now on further detail, the VM was working just fine and without any previous error on it's syslog kern.log etc..
A user triggered a Backup from Gui by choosing a typical (default backup from within the VM)
The backup started and then after a couple of minutes it was cancled by the user
That moment of cancellation the Guest VM got triggered with I/O Issue already posted above.
Any idea what got wrong?
