Hello,
I think this is a newbe question but I tested everything and, yes I
FTFM as best I could.
I'm evaluating ceph and so I setup a cluster of 4 nodes. The nodes
are KVM virtual machines named ceph01 to ceph04 all running Ubuntu
12.04.2 LTS each with a single osd named osd.1 though osd.4 respective
to the host they were running on. Each host also has a 1TB disk for
ceph to use '/dev/vdb1'.
After some work I was able to get the cluster up and running and even
mounted it on a test client host (named ceph00). I ran into issues
when I was testing a failure. I shut off ceph02 and watched via (ceph
--w) it recover and move the data around. At this point all is fine.
When I turned the host back on, it did not auto reconnect. I expected
this. I then send through many attempts to re add it but all failed.
Here is an output from: ceph osd tree

While I'm able to get it to be in the 'in' state, I cant seem to bring
it up.
Any ideas on how to fix this?
Glen,
try to bring up your OSD daemon with -d switch, this will probably give
you some information. (alternatively look in the logs)
Cheers,
