This bug still seems to be around in argonaut [0.48.2-0ubuntu2] and latest bobtail [ceph version 0.56.3 (6eb7e15a4783b122e9b0c85ea9ba064145958aa5)].

Both clusters only report a changing wd, rd always stays at the same very low (initial?) value.

Output of "rados df" from my bobtail cluster: http://pastebin.com/Ehc1cKyL

Output of "ceph -w" from my bobtail cluster: http://pastebin.com/A9f2012X

I only use qemu rbd images, could it be related to this? There are around 100 vms running, so there are a lot of reads going on for sure.

User 'gucki' from irc reports two testing clusters (one argo, one 0.56.3 (6eb7e15a4783b122e9b0c85ea9ba064145958aa5)) both still not updating rd numbers from 'rados df'. User paste: http://pastebin.com/Ehc1cKyL
