Cluster Help

[bhavicp]

Hi,
I've just got 4 Servers all running Proxmox i managed to get them clustered and it was working fine and then i changed hostnames on the slaves and i deleted the original slaves off the servers and tried to add them again, But i keep getting local node already part of cluster
Even though in the Control Panel it doesn't show them.
Also these servers are from OVH.

Pveca -l:

root@ss1:~# pveca -l
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = (unset),
        LC_ALL = (unset),
        LANG = "en_GB.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
CID----IPADDRESS----ROLE-STATE--------UPTIME---LOAD----MEM---ROOT---DATA
 1 : 91.121.86.190   M     A           00:50   0.46    18%    13%     0%

And i also did this on the servers: (slave and master)

root@ss2:~# rm -rf /etc/pve/cluster.conf
root@ss2:~# rm -rf /root/.ssh/known_hosts
root@ss2:~# rm -rf /etc/pve/cluster.cfg

Adding the slave:

root@ss1:~# pveca -a -h ss2.DOMAIN
perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
        LANGUAGE = (unset),
        LC_ALL = (unset),
        LANG = "en_GB.UTF-8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").
local node already part of cluster

Any help would be appreciated! Thanks !!

I think you need to do a "pveca -d ID" to the nodes before you readd them. I can't remember if you do that from the slaves or the master, but I think it's from the master.

Hey,
I already did that and as you can see from
pveca -l

CID----IPADDRESS----ROLE-STATE--------UPTIME---LOAD----MEM---ROOT---DATA
 1 : 91.121.86.XXX   M     A           14:06   0.00    19%    13%     0%

It only has that in thier.

1. stop the cluster sync. and cluster mirror services on all nodes.
2. remove the old cluster config from the nodes (rm /etc/pve/cluster.cfg and rm -r /etc/pve/master/)
3. make sure you have uniqe VMID´s on all nodes/master
4. join all nodes to the master again

yes, follow the instructions from my last posting. as the errors tells you that the node is already part of a cluster, a cluster.cfg is here.

did you get this (in the case you upgrade)?
