Best,

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 call ceph-deploy with sudo or run it as root if you are
logged in as a different user, because it will not issue sudo
commands
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.
