New install Proxmox 4.4
Three nodes

Following https://pve.proxmox.com/wiki/Ceph_Server

I get to this section and can proceed no further

Creating more Ceph Monitors
You should run 3 monitors, one on each node. Create them via GUI or via CLI. So please login to the next node and run:

node2# pveceph createmon
And execute the same steps on the third node:

node3# pveceph createmon

On node1 the command succeeded
mon.0 pteracluster Yes 10.10.10.1:6789/0

on node2 and node3 the command returns time out
on node2 and node3 pveceph status returns got timeout

rebooted both nodes - no change

ceph service is active on both nodes

on the node with the monitor created pveceph status returns

Now I do not know what changed. All I did was log in to them with ssh and get the information above.
But like yesterday I tried creating the other two monitors and today they were successfully created.
 
Yes may be there was a short network problem.
 
New problem - I have ntp installed on all three system yet...
osdCapture.PNG
 
So on the clock shew I set all three nodes to talk to my time server and the three nodes peer with each other.
Waiting to see if this clears it up.
 
Tried the create a vm to be stored on the cepf drive - got error

TASK ERROR: create failed - rbd error: rbd: error opening pool rbd: (2) No such file or directory

I did copy the key ring file per instructions.

root@pteracluster:~# cat /etc/pve/storage.cfg

username admin

content images
krbd 0

root@pteracluster:~# ls /etc/pve/priv/ceph/
RBD_Drive.keyring
 
OK saw my error in the key ring file - charged to
pteracluster.RBD_Drive.keyring

But now I get ...
TASK ERROR: create failed - rbd error: rbd: couldn't connect to the cluster!
 
Finally got it working. Had to remove the RDB storage and create on with the proper ceph pool name and proper keyring name.

Created a VM and now I will test drive it.
