Joao, Is there a reason you aren't putting OSDs on the Pis? Do you expect that the OSD won't run on the Pi?
The question really isn't about why I'm not putting the OSDs on the pi's but why I'd prefer to put them on the Cubietruck: unlike the pi, cubietruck has a SATA connection.
Besides, yeah, the Pi doesn't have much RAM anyway, and although I'm doing it just for the kicks of it and don't aim at a performing cluster, I don't see the 512MB of RAM to be enough for a mon, an OSD and the overall OS.

I think Joao was going to try that, not sure if he ever got around to it though. I got as far as hitting some missing leveldb dependency. Then decided to distcc and cross-compile Ceph using my desktop, but messed the toolchain somehow and have been attending to figuring out that every now and then but to no avail yet. My best guess atm is that regardless of being able to compile it on the pi, we're going to hit some missing dependencies anyway rendering the whole task mighty annoying. I'm hoping to be able to cross-compile a static version of the binaries and have a couple of monitors on the pi and an OSD on a cubietruck by Christmas :) -Joao Mark On 12/03/2013 09:03 AM, Alfredo Deza wrote: On Tue, Dec 3, 2013 at 9:56 AM, Shlomo Dubrowin <shlomo@xxxxxxxxxxxx <mailto:shlomo@xxxxxxxxxxxx>> wrote: Alfredo, I started that way, but I run into an error: $ ceph-deploy install baxter [ceph_deploy.cli][INFO ] Invoked (1.3.3): /usr/bin/ceph-deploy install baxter [ceph_deploy.install][DEBUG ] Installing stable version emperor on cluster ceph hosts baxter [ceph_deploy.install][DEBUG ] Detecting platform for host baxter ...

Yes, always with sudo unless you are root, which is the reason why ceph-deploy will not use that in the output. $ sudo env DEBIAN_FRONTEND=noninteractive DEBIAN_PRIORITY=critical apt-get -q -o Dpkg::Options::=--force-__confnew --no-install-recommends --assume-yes install -- ceph ceph-mds ceph-common ceph-fs-common gdisk Reading package lists...

It is possible that you have something else in that machine that is saying that 0.43 is the version you should be getting. Have you tried to install with ceph-deploy?: ceph-deploy install baxter and the versions I received are what I got.

The first thing I noticed is that the command lsb_release -sc specified in the Ceph Deploy setup provides n/a even though the answer should be wheezy. I manually changed the /etc/apt/sources.list.d/ceph.__list to specify wheezy. I've installed ceph-deploy and setup the keys to communicate between the deploy Raspberry Pi and all the Raspberry Pis including the system reunning ceph-deploy. When I tried to run ceph-deploy install <node1> the installation failed.

So I guess I have 2 questions: How can I determine which ceph-deploy goes with which ceph and how can I correct this apparent mismatch? I don't think there was a ceph-deploy per-se that would've worked for that Ceph version. I believe that ceph-deploy is very backwards compatible for a few Ceph versions. At the very least we should fully support the latest 3 major versions and we special case a few commands depending on the version installed. But like I mentioned, the Ceph version you have installed seems like a very very old one. Should I be looking at just using local ceph commands to configure this by hand? Are there instructions on how to do this by hand? If you must have that version I don't think there is any option here but to do it by hand and avoid ceph-deploy. For docs, I think that might be even more difficult to do as you would need to go to the tag for that version and look at the docs for that tag in the repository. Then again, what is the reason for using that version? Thank you.
