Jonas,
You can query the admin sockets of your monitors and osds get a json
listing of their running configuration. The command will look something
like:
# ceph --admin-daemon /var/run/ceph/ceph-mon.a.asok config show
# ceph --admin-daemon /var/run/ceph/ceph-osd.0.asok config show
You can then inject new settings to running daemons with injectargs:
# ceph tell osd.* injectargs '--osd_max_backfills 10'
Or, your can add those to ceph.conf and restart the daemons.
Cheers,
Mike Dawson

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?

Perfect, that worked very well. Thanks a lot.
Another question:
Using http://ceph.com/howto/deploying-ceph-with-ceph-deploy/ as a guide to set up my test-cluster I now have a working cluster with 12 osd's in and up. I've create a client, a 10gb rbd volume, mounted it, written data all good.
Looking at my ceph.conf it seems it's using all defaults:
[root@ceph02 ~]# cat /etc/ceph/ceph.conf [global] fsid =
f865694c-7a50-46a9-9550-f6b160c00313
mon_initial_members = ceph02, ceph03, ceph04 mon_host =
10.130.21.33,10.130.21.34,10.130.21.42
auth_supported = cephx
osd_journal_size = 1024
filestore_xattr_use_omap = true
Is there any way to dump the default running config to the config-file so I can start tinkering around?
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. How do I achieve this?
Thanks a lot in advance!
Kind regards
Jonas

Hi all,
I am seeing some weirdness when trying to deploy Ceph Emperor on
fedora 19 using ceph-deploy. Problem occurs when trying to install
ceph-deploy, and seems to point to the version of pushy in your repository:
Since ceph-deploy version 1.3 there is no longer a requirement on
pushy. You should update to the latest version (currently at 1.3.3)
[root@ceph02 ~]# yum install ceph-deploy

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles -nodigest
To work around this I tried to use pip to install pushy 0.5.3:

Downloading pushy-0.5.3.zip (48kB): 48kB downloaded
Running setup.py egg_info for package pushy

Running setup.py install for pushy
Successfully installed pushy
Cleaning up...
Verifying:
[root@ceph02 ~]# pip list | grep pushy
pushy (0.5.3)
However the installer does not seem to notice that pushy is there,
and it fails on the same dependency with the same error.
Any clue what I'm doing wrong here?
Kind regards
