Web interface for cluster not working

[rsauvat]

Hi

I have been using Proxmox in cluster configuration for 3 month without problem with 2 nodes (1 master , 1 slave). The master was version 1.4 and the slave 1.5. It worked well I was able to manage all my containers with the virtual interface from the master. Now I have a third Proxmox to add to the cloud and it broke everything.

When I delete the configuration file "/etc/pve/cluster.cfg" and stop all demons ("pvetunnel", "pvemirror") I can see in the web interface my virtual machines but I do pveca -c on the master the command executes successfully but the I can't see the informations on the virtual machines and I get this error "Unable to get data for Cluster Node 0".

And in the apache's log

proxwww[30251]: Can't use string ("") as a HASH ref while "strict refs" in use at /usr/share/perl5/PVE/HTMLUtils.pm line 389.

I tried to make the second proxmox a master and I have the same error.
And if I add a node to the master the web interface is still not working but the command pveca -l show me both nodes and the cluster seams to work.

I tried updating to 1.5 but it didn't change anything.

root@proxmox# pveversion -v
pve-manager: 1.5-8 (pve-manager/1.5/4674)
running kernel: 2.6.24-8-pve
pve-kernel-2.6.24-8-pve: 2.6.24-16
qemu-server: 1.1-11
pve-firmware: 1.0-3
libpve-storage-perl: 1.0-10
vncterm: 0.9-2
vzctl: 3.0.23-1pve8
vzdump: 1.2-5
vzprocps: 2.0.11-1dso2
vzquota: 3.0.11-1dso1

If someone have an idea because I already have 10 production containers running and I need to control them easily. Any help would be greatly appreciated

Have you tried NFS share? Is it still running? Faulty NFS share might break the webconsole.

Just a guess - try to delete /var/lib/pve-manager/vzlist

# rm /var/lib/pve-manager/vzlist

Does that help?

Thanks for the quick replies.

While typing an answer to explain further more the problem I find the solution. The file /etc/pve/cluster.cfg had the rights to 640 for user root. This is due to my umask 0027. I set the file to chmod 644 and it worked. So the cluster was showing correctly when used in command line with pveca -l. But it breaks the web ui because the web server user can't read the file.

Anyway thank you for the help.
