The rook command supports the following sub-commands:

  1. purge-osd <osd-id> [--force] : purge osd permanently remove an OSD from the cluster. Multiple OSDs can be removed in a single command with a comma-separated list of IDs.
  2. version: version prints the rook version.
  3. status: status print the phase and conditions of the CephCluster CR
  4. status all: status all print the phase and conditions of all CRs
  5. status <CR>: status cr print the phase and conditions of CRs of a specific type, such as 'cephobjectstore', 'cephfilesystem', etc

!!! warning Data loss is possible when passing the --force flag if the PGs are not healthy on other OSDs.
