Trying out the "quick" installation instructions, using four Ubuntu
Server 12.04 VMs, ceph-deploy aborts with the following error:

I tried putting my ssh key on node1/2/3, and ssh'ing into the admin node
with agent forwarding enabled. No joy.
There is a warning in the instructions which says:
Do not callceph-deploywithsudoor run it asrootif you are logged in as a
different user, because it will not issuesudocommands needed on the
remote host
Also all the instructions show "sudo" wherever needed, so it seems
you're supposed to run all this as a normal user.
However so far the only way I've been able to get this script to work is
to "sudo -s", and then run it ceph-deploy as root (after setting a root
password on node1/node2/node3)
Something missing from the instructions perhaps?
Thanks,
Brian.
