CephFS subvolume groups

You can create, list, fetch absolute path, and remove Ceph File System (CephFS) subvolume groups. subvolume groups are abstractions at a directory level that effects policies. For example, file layouts, across a set of subvolumes.

Note: The subvolume group snapshot feature is not supported. You can only list and remove the existing snapshots of these subvolume groups.
Before working with Ceph File System subvolume groups be sure that you have:
  • A working IBM Storage Ceph cluster with CephFS deployed.
  • A minimum read access on the Ceph Monitor.
  • Read and write capability on the Ceph Manager nodes.
