Different zpools for different containers

Markus_Heckmann · July 17, 2018, 5:33pm

May be this was answered. I couldnt find it. Similar https://discuss.linuxcontainers.org/t/mounting-zfs-datasets-to-containers/464/5 but I want my root partition of my container to be on a different zpool itself? Any suggestions.
At the moment all containers get mounted at the same ZFS zpool.
Thx

Create multiple LXD storage pools and specify the one you want with -s during launch.

thanks a lot for your quick help. Just typing the exact command for future use.
lxc storage create pool4TB zfs source=/dev/sdX zfs.pool_name=zpool4TB
lxc launch images:ubuntu/xenial xenial-on-4TB -s pool4TB

# Storage configuration
LXD supports creating and managing storage pools and storage volumes.
General keys are top-level. Driver specific keys are namespaced by driver name.
Volume keys apply to any volume created in the pool unless the value is
overridden on a per-volume basis.
