Hi all,

I'm using ceph Octopus version and deployed it using cephadm. The ceph documentation provides 2 ways for creating a new cephfs volume:

1. via "ceph fs volume create ..." - I can use this and it works fine with the MDS automatically deployed but there is no provision for using EC with the data pool

See "Using EC pools with CephFS" in https://ceph.io/community/new-luminous-erasure-coding-rbd-cephfs/ I will make a note to improve the ceph documentation on this. -- Patrick Donnelly, Ph.D. He / Him / His Principal Software Engineer Red Hat Sunnyvale, CA GPG: 19F28A586F808C2402351B93C3301A3E258DD79D
