# Create a Ceph FS

* Create a pool `rancher-high-prio-cephfs-metadata` (replicated)
* Create a pool `rancher-high-prio-cephfs-data` (replicated) or
* Optionally create a pool `rancher-high-prio-cephfs-root` (replicated) and `rancher-high-prio-cephfs-data` (erasure coded)

```bash
ceph fs new  rancher-high-prio-cephfs rancher-high-prio-cephfs-metadata rancher-high-prio-cephfs-data
ceph auth get-or-create-key client.rancher-high-prio-admin mds 'allow *' mgr 'allow *' mon 'allow *' osd 'allow * pool=rancher-high-prio-cephfs-metadata, allow * pool=rancher-high-prio-cephfs-data'
