LXD/Storage Pools

This page lists information on the creation of LXD storage pools.

A BTRFS storage pool can be created using the following command:

root # emerge btrfs-progs
root # lxc storage create btrfs-1tb-1 btrfs source=/dev/sda4
root # lxc storage set btrfs-1tb-1 btrfs.mount_options compress=lzo

For ZFS, compression should be enabled by default:

root # lxc storage create zfs-1tb-1 zfs source=/dev/sdb

For more control over your storage pool, you can create it first using ZFS, and then add it as follows:

root # zpool create -f lxd-pool /dev/sda /dev/sdb 
root # zfs set compression=zstd lxd-pool
root # lxc storage create lxd-pool zfs source=lxd-pool
Storage pool lxd-pool created

The above example creates a striped zpool and allows compression to be set explicitly to your preferred setting (there is no easy way I can find to create a striped zpool using the lxc storage create command directly.)
