   Example output:

   # Filesystem  Subvolume Subvolumegroup State
   # ocs-storagecluster-cephfilesystem csi-vol-427774b4-340b-11ed-8d66-0242ac110004 csi stale
   # ocs-storagecluster-cephfilesystem csi-vol-427774b4-340b-11ed-8d66-0242ac110005 csi stale

2. Delete the stale subvolumes:

   odf subvolume delete <subvolumes> <filesystem> <subvolumegroup>

   Replace <subvolumes> with a comma separated list of subvolumes from the output of the first command. The subvolumes must be of the same filesystem and subvolumegroup.

   Replace <filesystem> and <subvolumegroup> with the filesystem and subvolumegroup from the output of the first command.

   For example:

   odf subvolume delete csi-vol-427774b4-340b-11ed-8d66-0242ac110004,csi-vol-427774b4-340b-11ed-8d66-0242ac110005 ocs-storagecluster csi

   Copy to Clipboard Toggle word wrap

   Example output:

   # Info: subvolume csi-vol-427774b4-340b-11ed-8d66-0242ac110004 deleted
   # Info: subvolume csi-vol-427774b4-340b-11ed-8d66-0242ac110004 deleted
