Is it possible to create an EC backed RBD via ceph-iscsi tools (gwcli,
rbd-target-api)? It appears that a pre-existing RBD created with the rbd
command can be imported, but there is no means to directly create an EC
backed RBD. The API seems to expect a single pool field in the body to work
with.
Perhaps there is a lower level construct where you can set the metadata of
a particular RADOS pool to always use Pool X for data-pool when using Pool
Y for RBD header and metadata. This way the clients, in our case ceph-iscsi
needn't be modified or concerned with the dual-pool situation unless
explicitly specified.
For out particular use case we expose limited functionality of
rbd-target-api to clients and it would be helpful for them to keep track of
a single pool and not be concerned with two pools but if a data-pool and a
"main" pool could be passed via the API that would be okay too.
Thanks a lot.
