I mean, I have OSD's and MON's running now, but I see no mention of them in the current config file (/etc/ceph/ceph.conf) so backing that file up would not allow me to see where monitors/objectstores/journals where placed. Is there a nifty command that allows me to push these defaults to something that can be used as a config file that allows me to see how it was setup once I am done with my tests? I want to be able to do performance tests that that I can attach to individual configs which allows me to revert to the best config found for the ultimate performance once I have it tuned and compared the data? -----Original Message----- From: Alfredo Deza [mailto:alfredo.deza@xxxxxxxxxxx] Sent: Thursday, December 05, 2013 3:34 PM To: Jonas Andersson Cc: ceph-users@xxxxxxxx Subject: Re: ceph-deploy 1.2.2 vs fedora 19 On Thu, Dec 5, 2013 at 9:18 AM, Jonas Andersson <Jonas.Andersson@xxxxxx> wrote: > Perfect, that worked very well.

What do you mean by dump? You can backup that copy which is the one that ceph-deploy uses and use a new one and push it to your nodes and try that way "ceph --show-config" seems to show all parameters running, but I don't see any mentioning of the monitors/osd's at all? > > Last question: > I had a too low number of pgs, which caused a health warning. Since I type a lot faster than I think sometimes I adjusted the value to 128 (ceph osd pool set rbd pg_num 128), which turned out to be too high, but I cant seem to be able to tune it down again.
