Where can I see this VM zvol?

I’m trying to use the new Instances tab on TrueNAS 25.04-RC.1.

I can’t see it anywhere on my designated pool…

If I need to migrate it to somewhere else, how to do it?

Thanks.

zfs list -t volume
admin@truenas[~]$ zfs list -t volume
zsh: command not found: zfs

Try sudo zfs list when you’re using the admin account

NAME                                                                    USED  AVAIL  REFER  MOUNTPOINT
Apps/.ix-virt/custom/default_ubuntu-24.04.2-live-server-amd64.iso.iso  3.00G   433G  3.00G  -
Apps/.ix-virt/virtual-machines/ubuntu-server.block                     4.24G   433G  4.24G  -

I can’t see my VM root disk on TrueNAS GUI.

If I need to migrate it to another server, how to do it?

Why use sudo when root privileges are not necessary? This “problem” is a simple matter if the search path. Type /sbin/zfs ... and all is well. Unix 101, seriously this time.

Or edit your users .profile, .bashrc or whatever matches the shell and add /sbin to the path.

Like with any instance of ZFS datasets or volumes from one machine to another one:

root# zfs send Apps/.ix-virt/virtual-machines/ubuntu-server.block | gzip -c | ssh root@my.new.server "gzip -dc | zfs receive Apps/.ix-virt/virtual-machines/ubuntu-server.block"

For volumes you do not even need to create a snapshot, because one will be created automatically by zfs send.
