Migration failed

[Matus]

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__

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?

Hi,

can you provide a bit more information about your CT.
The config and the usage would helpful.

Is samba installed on 'alto'?
please send the output of this command which is executed on 'alto'

zfs get sharesmb

 

[Matus]

We have subscriptions (eg pve1c-ec6a8c4f9d) on both servers,
but it looks like samba is not installed on alto.
