Managing Ceph File System volumes, subvolume groups, and subvolumes

Edit online

Use IBM’s Ceph Container Storage Interface (CSI) to manage Ceph File System (CephFS) exports. This also allows you to use other services, such as OpenStack’s file system service (Manila) by having a common command-line interface to interact with.

The volumes module for the Ceph Manager daemon (ceph-mgr) implements the ability to export Ceph File Systems (CephFS).

The Ceph Manager volumes module implements the following file system export abstractions:
  • CephFS volumes
  • CephFS subvolume groups
  • CephFS subvolumes
