Hello everybody,
At cloud.nl we are going to use Ceph. So I find it a good idea to get
some handson experience with it, so I can work with it :). So I'm
installing a testcluster in a few VirtualBox machines on my iMac, which
runs OS X 10.9.4 offcourse. I know I will get a lousy performance, but
that's not the objective here. The objective is to get some experience
with Ceph, to see how it works.
But I hit an issue during the initial setup of the cluster. When I'm
done installing everything and following the howto's on ceph.com (the
preflight <http://ceph.com/docs/master/start/quick-start-preflight/> and
the Storage Cluster quick start
<http://ceph.com/docs/master/start/quick-ceph-deploy/>) I need to run
ceph health to see that everything is running perfectly. But it doesn't
run perfectly, I get the following output:
ceph@ceph-admin:~$ ceph health
HEALTH_WARN 192 pgs incomplete; 192 pgs stuck inactive; 192 pgs stuck
unclean
And it stays at this information, it never ever changes. So everything
is really stuck. But I don't know what is stuck exactly and how I can
fix it. Some more info about my cluster:
ceph@ceph-admin:~$ ceph -s
cluster d31586a5-6dd6-454e-8835-0d6d9e204612
health HEALTH_WARN 192 pgs incomplete; 192 pgs stuck inactive; 192
pgs stuck unclean

I'm running on Ubuntu 14.04.1 LTS Server. I did try to get it running on
CentOS 6.5 too (CentOS 6.5 is my actual distro of choice, but Ceph has
more affinity with Ubuntu, so I tried that too), but I got exactly the
same results.
But because this is my first install of Ceph I don't know the exact
debug commands and stuff. I'm willing to get this working, but I just
don't know how :). Any help is appreciated :).
Met vriendelijke groet/With kind regards,
Tijn Buijs
