# ZFS Swan runs its root on ext4. The ZFS drives are managed imperatively (this [disko configuration](../disks/zfs.nix) is an unused work-in-progress). The basic ZFS settings are managed [here](../modules/nixos/hardware/zfs.nix). ## Creating a New Dataset ``` sudo zfs create tank/mydataset sudo zfs set compression=zstd tank/myzstddataset sudo zfs set mountpoint=/data/mydataset tank/mydataset ```
