Hello there, I started to push data into my ceph cluster. There is something I cannot understand in the output of ceph -w. When I run ceph -w I get this kinkd of output: 2015-03-25 09:11:36.785909 mon.0 [INF] pgmap v278788: 26056 pgs: 26056 active+clean; 2379 MB data, 19788 MB used, 33497 GB / 33516 GB avail 2379MB is actually the data I pushed into the cluster, I can see it also in the "ceph df" output, and the numbers are consistent. What I dont understand is 19788MB used. All my pools have size 3, so I expected something like 2379 * 3. Instead this number is very big. I really need to understand how "MB used" grows because I need to know how many disks to buy. Any hints ? thank you.
