Currently we're running a test cluster with 1 mon, 1 radosgw and 2 osds. RGW runs on the same host as the mon while the osds recides on two different servers. We have thought of maybe running more than 1 osd on each storage server, where the osds use different disks of course - is this something reasonable or would performance/stability suffer?
Is there any recommendation against running rgw/mon on the same server? Would a better setup be to put osd/mon/rgw on each server and loadbalancing rgw? Of course we might add more osd:s at some point and I guess we don't want to run mons/rgw on those. Also, on Ubuntu 12.04, does anybody have experience with ceph on btrfs performance or is the recommendation still to run on xfs? All this is for running only the object storage part of ceph (only accessed through RGWs S3-interface).
