# 1.Display the CephFS status to determine the MDS ranks.
ceph fs status

# 2.Mark the CephFS as down:
ceph fs set FS_NAME down true

# 3.Display the status of the CephFS to determine it has stopped:
ceph fs status

# 4.Fail all MDS ranks shown in the status of step one:
ceph mds fail RANK

# 5.Remove the CephFS:
ceph fs rm FS_NAME --yes-i-really-mean-it

# 6.Verify that the file system is removed:
ceph fs ls

# 7.Optional: Remove the pools that were used by CephFS.
     # i.On a Ceph Monitor node, list the pools:
     ceph osd pool ls

     # ii.Remove the metadata pool:
     ceph osd pool delete CEPH_METADATA_POOL CEPH_METADATA_POOL --yes-i-really-really-mean-it

     # iii.Remove the data pool:
     ceph osd pool delete CEPH_DATA_POOL CEPH_DATA_POOL --yes-i-really-really-mean-it
