Yeah, I recall trying that on the Ubuntu-based Ceph cluster at work, and Ceph still wasn't happy, hence I've gone the route of making the partition owned by the ceph user. > Did you poke around any of the ceph howto's on the gentoo wiki?

One thing that has worried me is since you can only deploy one MDS, what happens if that MDS goes down? If it's simply a case of spin up another one, then fine, I can put up with a little downtime. If there's data loss though, then no, that's not good. -- Stuart Longland Systems Engineer _ ___ \ /|_) | T: +61 7 3535 9619 \/ | \ | 38b Douglas Street F: +61 7 3535 9699 SYSTEMS Milton QLD 4064 http://www.vrt.com.au _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
