Wanting to play around with Ceph, I have a single-node Ceph with 1 monitor and 3 OSDs running on a VM. I am loving the flexibility that Ceph provides (and perhaps just the novelty of it). I've been planning for some time to build a NAS for home use and seriously thinking about running Ceph on real hardware (Core2 Quad Q9550 with 8-16GB RAM and 3x 4TB HDD) as the backing store. Given my resources, I'd still only run a single node with 3 OSDs and replica count of 2. I'd then have a VM mount the a Ceph RBD to serve Samba/NFS shares. I realize mine is not the usual or ideal use case for Ceph, but do you see any reason not to do this? I don't need high-performance, just good enough to serve 2 movie streams, which my test VM is already able to do, and it will be one of my backup data stores, not main store (yet). I just like Ceph's ability to add storage as needed with minimal fuss. Also, I have some older HD's (500-750GB, 5+ years old) that are still chugging along fine. I don't want to entrust main data to them, but feel I could use them for temporary backfill purposes. If I add them to another node, can Ceph be configured to use them only for backfill purposes, should the need arise? Anyway, just wanted a sanity check, in case the novelty of running Ceph is clouding my judgement. Feel free to set me straight if this is just a silly idea for such relatively small scale storage! _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
