add 3.0 host to 2.3 cluster?

[rjacobsen]

Hello,

Should it be possible to add a 3.0 host to a 3.0 cluster? I'm adding a new node to my cluster, so I figured I would install it with proxmox 3.0 as I plan on upgrading the rest of the cluster shortly. Should this be fine? I am having an issue running pvecm add:

root@vm3:~# pvecm add 172.16.40.1
copy corosync auth key
stopping pve-cluster service
Stopping pve cluster filesystem: pve-cluster.
backup old database
Starting pve cluster filesystem : pve-clustercan't create shared ssh key database '/etc/pve/priv/authorized_keys'
.

   Starting cman... [  OK  ]

(It sits waiting for quorum indefinitely)

Thanks,
Richard

I'm currently using udpu in cluster.conf because I'm running over IB over connected mode. This is the third (and first 3.0) node. The other 2.3 nodes seem happy.

The first time I added the node, I figured it failed because I had forgotten to add all of the host entries prior. So I:
On vm1:

pvecm delnode vm3

On vm3 (the new node)

service cman stop
rm /etc/cluster/cluster.conf
rm -rf /var/lib/pve-cluster/* /var/lib/pve-cluster/.*
service pve-cluster stop
rm -rf /var/lib/cluster/*
reboot
...
pvecm add vm1

But I still get that error again. All of the servers clocks are synchronized, and they all have appropriate host entries.

Hi Dietmar,

Thanks for the help, when I was reading the multicast notes I saw that multicast should work over connected mode. I tried switching back to that, and was able to add the node successfully!
