Not sure how much of a difference it makes at this point, but I also tend to use -i size=2048.
Well, while running through the Ceph and XFS ML, I came across those options several times.
Looks like you guys are using AGPL V3. I don't actually know too much about that license other than that it's fairly similar to GPL V3 and apparently somewhat compatible. Any particular reason you chose it?
No particular reason for this in this context. AGPL is eNovance default licensing model for all our contributions.

Hello everybody,
Quite recently François Charlier and I worked together on the Puppet
modules for Ceph on behalf of our employer eNovance. In fact, François
started to work on them last summer, back then he achieved the Monitor
manifests. So basically, we worked on the OSD manifest. Modules are in
pretty good shape thus we thought it was important to communicate to the
community. That's enough talk, let's dive into these modules and explain
what do they do. See below what's available:
Neat. :)
* Testing environment is Vagrant ready.
* Bobtail Debian latest stable version will be installed
* The module only supports CephX, at least for now
* Generic deployment for 3 monitors based on a template file
examples/common.sh which respectively includes mon.sh, osd.sh, mds.sh.
* Generic deployment for N OSDs. OSD disks need to be set from the
examples/site.pp file (line 71). Puppet will format specified disks in
XFS (only filesystem implemented) using these options: `-f -d
agcount=<cpu-core-number> -l size=1024m -n size=64k` and finally mounted
with: `rw,noatime,inode64`. Then it will mount all of them and append
the appropriate lines in the fstab file of each storage node. Finally
the OSDs will be added into Ceph.

All the necessary materials (sources and how-to) are publicly available
(and for free) under AGPL license on Github at
https://github.com/enovance/puppet-ceph . Those manifests do the job
quite nicely, although we still need to work on MDS (90% done, just need
a validation), RGW (0% done) and a more flexible implementation
(authentication and filesystem support). Obviously comments,
constructive critics and feedback are more then welcome. Thus don't
hesitate to drop an email to either François (f.charlier@xxxxxxxxxxxx
<mailto:f.charlier@xxxxxxxxxxxx>) or I (sebastien@xxxxxxxxxxxx
<mailto:sebastien@xxxxxxxxxxxx>) if you have further questions.
