Error: Common start logic: Failed to start device ‘vda’: Could not mount storage volume “XXXX” of type “custom” on storage pool “syspool”: Failed to mount ZFS filesystem: Failed to run: zfs mount syspool/custom/XXXX: cannot mount ‘syspool/custom/XXXX’: filesystem already mounted.
Try lxc info --show-log weed for more info

If I check with zfs mount it’s not mounted.

Only a host reboot solved the issue.

There is a mention of vda. Is this from a VPS?

I just named the device vda when attaching it to the container.
