HA Issues

[adamb]

Hey all new to proxmox and very impressed!!

I am in the process of setting up a 2 node cluster with a dual DRBD primary/primary setup. I am using the IMM of our IBM servers as a fence device. After setting everything up I am hitting an issue with the HA tab on the gui. Now when accessing the HA tab I am seeing the following message and unsure what exactly the issue could be. The virtual machines are still running as they should and I can migrate from NodeA to NodeB with ease. I have yet to test the HA features as I figured this issue would cause problems. Any input is greatly appreciated. I am seeing the following message when trying to access the HA tab of the gui. I am unable to get past this error as it doesn't allow me to do anything on the tab anymore.

Please can you post the file /etc/pve/cluster.conf

root@proxmox2:~# cat /etc/pve/cluster.conf
<?xml version="1.0"?>
<cluster config_version="4" name="ccs-test">
<cman keyfile="/var/lib/pve-cluster/corosync.authkey"/>
<clusternodes>
<clusternode name="proxmox1" nodeid="1" votes="1"/>
<clusternode name="proxmox2" nodeid="2" votes="1"/>
</clusternodes>
<rm>
<pvevm autostart="1" vmid="100"/>
<pvevm autostart="1" vmid="101"/>
</rm>
</cluster>

Also when creating the cluster.conf.new should this be moved to the cluster.conf itself or left as cluster.conf.new? I appreciate the input!!

Just tested HA functionalities and they seem to be working quite well even with this issue. I can power down either node and all virtual machines fail over properly. Must be something simple in the config I am missing!

you mention configured fencing but you posted a cluster.conf without it.?

 

[adamb]

The fencing configuration is in cluster.conf.new. I was unsure if it needed to be copied to cluster.conf because the wiki states nothing about. So I left as is. HA is working though as it should. Still getting the error though in the HA tab.

 

[tom]

check your config, post cluster.conf.new

 

[adamb]

Here is my cluster.conf.new

root@proxmox1:~# cat /etc/pve/cluster.conf.new
<?xml version="1.0"?>
<cluster config_version="4" name="ccs-test">
<cman expected_votes="1" keyfile="/var/lib/pve-cluster/corosync.authkey" two_node="1"/>
<fencedevices>
<fencedevice agent="fence_ipmilan" name="ipmi1" lanplus="1" ipaddr="10.80.12.126" login="USERID" passwd="PASSW0RD" power_wait="5"/>
<fencedevice agent="fence_ipmilan" name="ipmi2" lanplus="1" ipaddr="10.80.12.131" login="USERID" passwd="PASSW0RD" power_wait="5"/>
</fencedevices>
<clusternodes>
<clusternode name="proxmox1" nodeid="1" votes="1"/>

</fence>

</fence>
< clusternode name="proxmox2" nodeid="2" votes="1"/>

Is there an unnecessary space before clusternode?

Is there an unnecessary space before clusternode?

Good catch, that did the trick!!

Then go to the HA tab and commit the changes (that copies cluster.conf.new to cluster.conf)

 

[adamb]

I am missing the "commit change" button. All I have is revert change and activate.

When hitting activate I am getting the following error. "config validation failed: unknown error 500"

Then you still have errors in the cluster.conf.

Please check with:

# ccs_config_validate -l /etc/pve/cluster.conf.new

 

[adamb]

Here are the outputs

root@proxmox2:/etc/pve# ccs_config_validate -l /etc/pve/cluster.conf.new
tempfile:10: element fence: Relax-NG validity error : Expecting element clusternode, got fence
tempfile:9: element clusternode: Relax-NG validity error : Element clusternodes has extra content: clusternode
Configuration fails to validate

 

[adamb]

Pinned it down myself. I was missing </cman> at the top. I also had some opening and ending tag mismatches. The config validated and successfully Activated in the GUI. I really appreciate all the help!!
