Everytime I need to create a cluster in proxmox I suffer a bit PITA. But now I simply can't do it. I've reinstalled several times and deleted and recreated the cluster again and again. No luck.
Multicast does not work in this network, so I used unicast. There are another proxmox cluster in the same network and it's working (it was very painfull also to install, but once I realized the problem was unicast and the mtu size, it works very well, except when adding a node, that always is another pain). So, I would like to explain how I'm doing this and perhaps I'm pretty obfuscated to see what is happening. I've installed two debian 7.1, LVM partitions (not necessary, but I did it anyway), and installed proxmox. The servers works as expected separately. The server p01 have the IP: 192.168.200.197 The server p02 have the IP: 192.168.201.191 The two networks are visible each other, and as cluster protocol is udp, it should work. Am I wrong? Then on p01, I've created the cluster with "pvecm create testcluster", it worked I've copied /etc/pve/cluster.conf to /etc/pve/cluster.conf.new, increased the version number and add transport="udpu" to the cman section and added the section <totem netmtu="1400" /> (I tried without it also). Then I've activated the new configuration throught the GUI. I've double checked /etc/hosts to assure they resolve the names through this mechanism. Then on p02 I tried to add the node with "pvecm add p01" (also tried with IP and also tried this command from p01, both with hostname and IP of the p02 node). root@p02:~# pvecm add p01 root@p01's password: copy corosync auth key stopping pve-cluster service Stopping pve cluster filesystem: pve-cluster. backup old database Starting pve cluster filesystem : pve-cluster. 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... [FAILED] Waiting for quorum... Well, it never works. The node waits for a quorum forever. I can see the p02 node on the p01 GUI (with a red light), but I have no access. If I run: root@p01:~# pvecm status Version: 6.2.0 Config Version: 2 Cluster Name: testcluster Cluster Id: 692 Cluster Member: Yes Cluster Generation: 1276 Membership state: Cluster-Member Nodes: 1 Expected votes: 1 Total votes: 1 Node votes: 1 Quorum: 1 Active subsystems: 5 Flags: Ports Bound: 0 Node name: p01 Node ID: 1 Multicast addresses: 239.192.2.182 Node addresses: 192.168.200.197 root@p02:~# pvecm status Version: 6.2.0 Config Version: 2 Cluster Name: testcluster Cluster Id: 692 Cluster Member: Yes Cluster Generation: 24 Membership state: Cluster-Member Nodes: 1 Expected votes: 2 Total votes: 1 Node votes: 1 Quorum: 2 Activity blocked Active subsystems: 1 Flags: Ports Bound: 0 Node name: p02 Node ID: 2 Multicast addresses: 239.192.2.182 Node addresses: 192.168.201.191 root@p01:~# pvecm nodes Node Sts Inc Joined Name 1 M 1276 2013-09-26 13:02:19 p01 2 X 0 p02 root@p02:~# pvecm nodes Node Sts Inc Joined Name 1 X 0 p01 2 M 24 2013-09-26 13:04:02 p02 And trying to access from p01 GUI to the local resources of p02, Appears the message "can't open '/etc/pve/authkey.pub' - No such file or directory (401)" As the /etc/pve/ mountpoint on p02 is a) read only and b) not the same than p01 (i.e: on p01 there are more files), and /etc/pve/authkey.pub is not in p02.
