I'm attempting to migrate a VM with a 650GB ZFS disk from a pve8 to pve9 host. When first trying to migrate the VM, it failed with the following:
To fix this, I ran zfs destroy datastore1/vm-104-disk-0@__migration__ which worked and the stale snapshot was removed. However, now when trying to migrate this VM, the output is stuck here:
Normally, it refreshes every second or so with progress, but this one is producing no output. Is this expected or is something broken?
Code:
