Hi,
I am trying to setup an erasure coded pool with rbd image.
The ceph version is Luminous 12.2.1. and I understand, since Luminous,
RBD and Cephfs can store their data in an erasure coded pool without use
of cache tiring.
I created a pool ecpool and when trying to create a rbd image, gets this
error.
==============
[cephuser@ceph-las-admin-a1 ceph-cluster]$ rbd create --size 20G
ecpool/ectestimage2
2017-10-12 10:55:37.992965 7f18857fa700 -1 librbd::image::CreateRequest:
0x55608e1e0c20 handle_add_image_to_directory: error adding image to
directory: (95) Operation not supported
rbd: create error: (95) Operation not supported
