I admit I don't remember. Probably "rwx" for both the mon and OSD instead of "*", but it's not a huge difference. > > Also, what is the state of the various *rank parameters?

In any case, while we don't recommend more than one *active* mds for stability reasons, there's a lot of plumbing to support multiple daemons (since that's the ultimate point). > For example, say I wanted to co-host mon and mds services, 3 or 5 of them. > What would appropriate settings for each be? You could just turn them all on; as long as you don't increase the max mds value the system will do something that looks right to you. -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
