I tried to migrate zfs LXC container from host with VE 4.4 to host with 5.2
Migration failed with this nessages:
....
20:51:29 26.8G rpool/ROOT/subvol-103-disk-1@__migration__
20:51:30 26.8G rpool/ROOT/subvol-103-disk-1@__migration__
cannot share 'rpool/ROOT/subvol-103-disk-1': smb add share failed
zfs send/receive failed, cleaning up snapshot(s)..

...

Some other containers migrate well.

Sharesmb on zfs look like this:
>zfs get sharesmb
NAME PROPERTY VALUE SOURCE
....
rpool/ROOT/subvol-103-disk-1 sharesmb off local
....

Could you help?
