Re: [ceph-users] Openstack VMs with Ceph EC pools
Thank you, Andrew and Jason for replying. Jason, Do you have a sample ceph config file that you can share which works with RBD and EC pools?

Correct, you can put an override in the "ceph.conf" file on your Cinder controller nodes: [client.cinder] rbd default data pool = XYZ You can also use Cinder multi-backend, each using a different CephX user id, to support different overrides for different device classes. > Thanks, > Andrew > ___ > ceph-users mailing list > ceph-users@lists.ceph.com > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com -- Jason ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com

I attempted it, but couldn't figure out how to get Cinder to specify the data pool. You can't just point Cinder at the erasure-coded pool since the ec pool doesn't support OMAP and the rbd creation will fail. Cinder will need to learn how to create the rbd differently, or there needs to be some override in ceph.conf.

[ceph-users] Openstack VMs with Ceph EC pools
Hi, Is anyone using Openstack with Ceph Erasure Coding pools as it now supports RBD in Luminous. If so, hows the performance? Thanks, Pardhiv Karri ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
