##### ISSUE TYPE
* Improvement Request
##### COMPONENT NAME
UI-Backend
##### CLOUDSTACK VERSION
4.14.0
##### CONFIGURATION
Cloudstack and Ceph object storage configuration.
##### OS / ENVIRONMENT
<!--
Information about the environment if relevant, N/A otherwise
-->
##### SUMMARY
<!-- Explain the problem/feature briefly -->
About this, we have an erasure code pool at ceph, so we can create an image and then we must specify where the metadata and data pool is located. When we add the erasure code pool as Storage in Cloudstack we can't set the datapool, so when we add a VM it shows an error. We asume that Cloudstack do something like this in Ceph:
_rbd create DISCO --size 4096 -p PoolErasure_
_rbd: create error: (95) Operation not supported_
**And must be:**
_rbd create --size 4096 --data-pool DataPool PoolErasure/DISCO_
Example:
https://documentation.suse.com/ses/6/html/ses-all/cha-ceph-erasure.html#ec-rbd
There is not a field at Cloudstack to set this, so it fails when creating a VM in this storage.
In replicated ceph configuration is working fine because there is just one Pool so you don't need to set more options at Cloudstack.
There is a way to set the data pool at cloudstack in other way?.

Yes, this is not a CloudStack thing. One needs to specify the data pool in the settings inside Ceph:
I use a similar setup with Ceph EC and I have configured this inside Ceph:
<pre>
wdh@mon-72-4-36:~$ sudo ceph config dump|grep pool
client advanced rbd_default_data_pool rbd-data *
wdh@mon-72-4-36:~$
</pre>
The pool **rbd** is defined in CloudStack, but internally all is stores in the rbd-data pool:
<pre>
wdh@mon-72-4-36:~$ sudo ceph df
--- RAW STORAGE ---
CLASS SIZE AVAIL USED RAW USED %RAW USED
hdd 1015 TiB 564 TiB 451 TiB 451 TiB 44.45
TOTAL 1015 TiB 564 TiB 451 TiB 451 TiB 44.45
--- POOLS ---
POOL ID PGS STORED OBJECTS USED %USED MAX AVAIL
device_health_metrics 1 1 13 MiB 126 39 MiB 0 112 TiB
rbd 2 64 197 MiB 853 673 MiB 0 112 TiB
rbd-data 3 512 281 TiB 73.45M 448 TiB 57.19 224 TiB
wdh@mon-72-4-36:~$
</pre>
So nothing needs to be changed here inside CloudStack.
