Thank you for your reply.
I created a erasure coded pool 'ecpool' and a replicated pool to
store metadata 'ec_rep_pool'
And created image as you mentioned :
rbd create --size 20G --data-pool ecpool ec_rep_pool/ectestimage1
But the image seems to be created in ec_rep_pool
============
[cephuser@ceph-las-admin-a1 ceph-cluster]$ rbd ls -l ecpool
[cephuser@ceph-las-admin-a1 ceph-cluster]$ rbd ls -l ec_rep_pool
NAME SIZE
PARENT
FMT PROT LOCK
ectestimage
20480M
2
ectestimage1
20480M
2
Is that how it suppose to work ?

The image
metadata still needs to live in a replicated data pool --
only the data blocks can be stored in an EC pool. Therefore,
when
creating the image, you should provide the "--data-pool
<pool-name>"
optional to specify the EC pool name.
