We are using a single pool for all our RBD images.
You could create different pools based on performance and replication needs. Say one with all SSDs and one with SATA. Then put your RBD images in the appropriate pool.
Each host is also using the same user. You could use a different user for each hypervisor but that would be up to you.

Hi Guys,Hoping to find help here as I can't seem to find anything on the net.I have a ceph cluster and I'd want to use rbd as block storage on our hypervisors (say 30) to mount drives to our guests. Would you create users and pools per hypervisor?As adding more pools to a cluster seems to be a problem if you're not sure how many pools you'll end up using, e.g. I kept adding more pools with pg_num 256 and now I'm at pool no. 4 and my cluster complains about 'too many PGs per OSD (324 > max 300)' - any ideas ?Cheers,Thomas_______________________________________________ceph-users mailing listceph-users@xxxxxxxxxxxxxxhttp://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
