Here's the docs on master and the recent LTS releases. http://docs.ceph.com/docs/firefly/rados/configuration/filesystem-recommendations/ http://docs.ceph.com/docs/hammer/rados/configuration/filesystem-recommendations/ http://docs.ceph.com/docs/master2/rados/configuration/filesystem-recommendations/ The documentation has NEVER recommended ext4.
