<pre>Hi All,<br><br>We want DeepSea to be able to "import" existing ceph clusters, for<br>example if you've used ceph-deploy in the past, and want to migrate to<br>DeepSea. I've implemented what you might call a rough outline of this<br>functionality at <a href="https://github.com/SUSE/DeepSea/commit/7a60715">https://github.com/SUSE/DeepSea/commit/7a60715</a> (i.e.<br>the implementation is incomplete), and would appreciate feedback on the<br>approach in general.<br><br>There's more detail in the commit, but essentially you use it like so:<br><br>1) Install salt on every ceph node.<br>2) Run the first two DeepSea stages, plus my extra importer bit.<br>3) The importer checks what ceph services are running on all the minions<br>(mon, mds, osd, rgw), and generates a policy.cfg reflecting the<br>currently running cluser.<br>4) Now you can keep using DeepSea as usual.<br><br>WARNING: Do *NOT* try step 4 with the current code. You WILL BREAK YOUR<br>CLUSTER. I'm just trying to get feedback on whether there's any large<br>holes in the general shape of this thing (I had an earlier experiment<br>where I was interrogating ceph.conf to find the MONs, then realised I'd<br>end up having to talk to the cluster to ask it where the OSDs were, so I<br>decided that checking for running services was going to be simpler).<br><br>Thanks,<br><br>Tim<o:p></o:p></pre>

Oh, this looks very promising. Eric was quite worried that we wouldn't have enough time and too many other priorities to get to this. Thanks for looking into it, Tim.<br>
