[SOLVED] Cluster is functioning properly but showing all nodes as OFFLINE on web GUI

[madyoda]

Hello all,

I'm sure you've all come across this issue before. I just managed to setup a Proxmox 4.4.1 cluster (pve-manager/4.4-1/eb2d6f1e (running kernel: 4.4.35-1-pve)) and everything seems to be working perfectly. There is quorum, all nodes see each other, they communicate fine (omping), the only storage is 'local' (/var/lib/vz) and no errors are being thrown (in syslog, etc).

My problem comes to the web GUI, where all nodes show offline (see: http://i.imgur.com/OIpgX5w.png ). On the Datacenter -> Summary page, proxmox shows everything as okay (see: http://i.imgur.com/hp99UxA.png ) but the nodes as 'offline' and it reflects below (see: http://i.imgur.com/kSaYkLc.png )

VM's are running perfectly on the 'kappa' node as I had them all on there before, but as the nodes are showing offline I cannot create a new VM as it tells me the specified node is offline.

If I navigate to the 'zeus' web panel, everything above is reflected apart from it showing the 'zeus' server IP address as apposed to the 'kappa' IP address (see: http://i.imgur.com/b9C0ZE6.png ) (note: both IP's start in 3 but they *are* different, just blurred)

I've been through google, restarted pvestatd, pve-cluster, corosync, etc multiple times but no avail.

Does anyone have any solutions/pointers?

Thanks in advanced

Hi,
is your time correct on both nodes?
show "pvecm status" the same from both nodes? And total votes 2?
Why is the thread marked as solved, if you need help?

Apologies, I forgot to click the post reply button on this.
I managed to solve it:

Alright, finally managed to fix it.

The problem was to do with hosts, as I was using a local 10.10.10.x VPN (I am using two OVH nodes), because I cannot multicast over the public network. By adding a few more entries in /etc/hosts (thanks to step 4 of this guide: https://forum.ovh.co.uk/showthread.php?7071-Poor-man-s-Proxmox-cluster-with-NAT ) and giving zeus a kick, they are now clustering perfectly and both showing online.

To show it better, here's a screenshot from before: https://i.imgur.com/kSaYkLc.png - you can see the IP for kappa starts with 3 which is my public IPv4.
Once fixed, it's now showing the following: http://i.imgur.com/Wbi7zqG.png which is now 100% working​
