Anyone using rrdtool with Ceph via rados or cephfs ?
If so, how many rrd files and how many rrd file updates per minute. We have a large population of rrd files that's growing beyond a single machine. We're already using SSD and rrdcached with great success, but it's not enough for the growth that's coming. A distributed file store would tick a lot of check boxes, but it needs to survive the high volume small write IOPS produced by rrdtool. Thanks, Steve
