Hi,
I have found some issues on ceph v0.61.2 on Ubuntu 12.10.
(1) "ceph-deploy osd create" command fails when using --cluster <name> option.
[root@host3 yuji_ceph]# ceph-deploy --cluster yuji osd create host1:sdb
Traceback (most recent call last):

This is a symptom of Python < 2.7, but you say Ubuntu 12.10; are all the
hosts running 12.10? Have you manually configured the hosts to use
Python < 2.7?
If the hosts are running < 2.7 on purpose, there's a fix for this in
git; see http://tracker.ceph.com/issues/5086, but it shouldn't be
happening on 12.10.
(2) "service ceph -a start/stop" command is accepted, but nothing happens.
root@host1:~# ceph osd tree
# id weight type name up/down reweight
-1 0.16 root default
-2 0.16 host host1
0 0.03 osd.0 up 1
1 0.03 osd.1 up 1
2 0.03 osd.2 up 1
3 0.06999 osd.3 up 1
root@host1:~# /etc/init.d/ceph -a stop
root@host1:~# ceph osd tree
# id weight type name up/down reweight
-1 0.16 root default
-2 0.16 host host1
0 0.03 osd.0 up 1

2 0.03 osd.2 up 1
3 0.06999 osd.3 up 1
If you're running on 12.10 with ceph-deploy, you're using Upstart, so
you probably want upstart commands (start ceph/stop ceph)
By the way, I could not find [osd], [host] and [mon] entry in the
/etc/ceph/ceph.conf anymore when I create ceph cluster using
"ceph-deploy". Is this information still stored somewhere?
Not directly; it's inferred from the presence of directories in
/var/lib/ceph. You can, of course, still add configuration options to
ceph.conf, it's just that you don't have to specify daemon
location/address there as you used to.
Thank you.
Yuji
