Support for EC pools [2] was added a bit later, targeted for Octopus (15.2.0), but it was also made available in an early point release of Nautilus (14.2.2). Please note that both Nautilus and Octopus releases are EOL and no longer supported though. By default, all RBD images are sparse. "rbd sparsify" can bring some of that sparseness back, hence the re- prefix. [1] https://github.com/ceph/ceph/pull/26226 [2] https://github.com/ceph/ceph/pull/27268 Thanks, Ilya
