Ceph » Linux kernel client

I'm new to Ceph, and want to do a fresh installation on Ubuntu 10.04 LTS.
Followed the instructions from: http://ceph.newdream.net/wiki/Installing_on_Debian with the exception that I only specified a single node in the config to start with.

Unfortuneately I didn't got far:

root@node0's password:
