Hello guys, please help me with this one, First, i've cases like this post: Code: http://forum.proxmox.com/threads/9466-2-node-cluster-second-node-gone-now-i-cannot-delnode-the-2nd-node-cause-of-no-quoru and before i solved the problem with that, my proxmox get the other error: Code: cman_tool: Cannot open connection to cman, is it running ? it happend to the master and slave (proxmox1 as a master) and (proxmox2 as a slave). Both of nodes has the same error when i start to pvecm status. This is the error messages when i start cman services (via web interface): 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... Cannot find node name in cluster.conf Unable to get the configuration Cannot find node name in cluster.conf cman_tool: corosync daemon didn't start Check cluster logs for details [FAILED] TASK ERROR: command '/etc/init.d/cman start' failed: exit code 1 Here's my cluster.conf: Code: <?xml version="1.0"?> <cluster name="GSPCLUSTER1" config_version="4"> <cman keyfile="/var/lib/pve-cluster/corosync.authkey"> </cman> <clusternodes> </clusternodes> </cluster> Is there a way to remove cluster or re-create the cluster in VE 2? and how to to this? because i'm not find this in VE 2 wiki. thx.
