Hi,
I want to test Ceph inside Amazon EC2. Therefore I compiled and installed ceph-0.19.1.tar.gz and ceph-kclient-0.19.1.tar.gz
Two Ubuntu instances are running inside EC2.
One server with cmon, cmds, and cosd and one client.
# cat /etc/ceph/ceph.conf

pid file = /var/run/ceph/$name.pid

[osd]

osd data = /srv/ceph/osd
[osd1]

What can I do at this point?
Thanks in advance
Christian
