Hi,
IIRC, i've successfully migrated a VM with local storage previously, but trying to do the same with an LXC container gives me error:
root@pve01:~# pct migrate 105 pve3
2019-03-06 13:51:24 starting migration of CT 105 to node 'pve3' (192.168.1.12)

root@pve01:~#

The container is shut down. Any idea how i can get it to migrate with local storage over to node pve3?

Thanks.
 
do all of your clusternodes have the same zfspools available ?
Please post the output of:
* `zpool status`
* `zfs list`
* `cat /etc/pve/storage.cfg`

No, not the pool i'm i'm trying to migrate to on node pve3. How does the pct migrate choose which storage on the destination node to migrate to?

Migrating containers from one node to the other and also changing the targetstorage is not supported ATM

move the volume to a pool available on all nodes and migrate afterwards.
