Unable to build a cluster with unicast

[mel128]

Hello there,

I'm trying to build for the first time a cluster with unicast ( used to do that in LAN where multicast works ). Two servers in a Vrack at OVH but I'm not sure that the problem is there.

First, a fresh install of both server, apt-get update and apt-get upgrade.

Added both servers in each /etc/hosts

127.0.0.1 localhost.localdomain localhost
5.39.XXX.XXX nsYYYYYY.ovh.net nsYYYYYY
178.33.XXX.XXX nsYYYYYY.ovh.net nsYYYYYY

Of course, XXX and YYYYYYY replace the real values .

On the first server :

# pvecm create test

/etc/pve/cluster.conf edited ( without double closing tag, the wiki page http://pve.proxmox.com/wiki/Multicast_notes#Use_unicast_instead_of_multicast is unclear because there is a "\>" at the end of the line, should be ">" without "\", right ? )

<?xml version="1.0"?>
<cluster name="test" config_version="1">

<cman keyfile="/var/lib/pve-cluster/corosync.authkey" transport="udpu">
</cman>

<clusternodes>
<clusternode name="nsYYYYYY" votes="1" nodeid="1"/>
</clusternodes>

</cluster>

Both server rebooted and then, trying to add the second server to the cluster.

On the second server :

# pvecm add IP-ADDRESS-OF-THE-FIRST-SERVER

Getting the error message : "unable to copy ssh ID"

I tried, on the first server :

# /etc/init.d/cman stop
# /etc/init.d/cman start

Cman seems running :

Starting cluster:
Checking if cluster has been disabled at boot... [ OK ]
Checking Network Manager... [ OK ]
Global setup... [ OK ]
Loading kernel modules... [ OK ]
Mounting configfs... [ OK ]
Starting cman... [ OK ]
Waiting for quorum... [ OK ]
Starting fenced... [ OK ]
Starting dlm_controld... [ OK ]
Tuning DLM kernel config... [ OK ]
Unfencing self... [ OK ]

What did I miss ? Thank for your help.

Michel.

try to run 'ssh-copy-id' manually and check why it fails (see 'man ssh-copy-id')

Do not mind Dietmar ... we pointed to another server :-/

Sorry for the noise.
