Hi guys!
my question is about wathdog and his trigger.

Code:
If the node has connection with the cluster and has quorum, the watchdog will be reset. If quorum is lost, the node is not able to reset the watchdog. This will trigger a reboot after 60 seconds.

can i set the trigger on 120 seconds, for example?
or disable trigger or watchdog?(this can be useful for mantenaince).
i read the doc about HA and i didn´t see how :S

thanks!
 
Hi, sorry but i have the same problem and this doesn´t work for me.

I installed a Test-Cluster with 3 Nodes and one Test-VM on shared Storage (NFS) to test the restart problem with the softwatchdog.

If HA isn´t enabled at all. (never enabled a VM to HA, never created a ressource group and so on), in the HA-Cluster view there is no "lrm" running and also no restart is triggered at all. (doesn´t matter if i cut off the network)

After that i enabled HA on my test-vm and created a testing HA-Group and the fencing works as expected.
But after that, it doesn´t matter if i disable the HA on the testvm or also delete the HA-Group, the fencing still persists (if network connection is lost, no quorum on the node holding the vm)

So the option to remove all VM´s from HA isn´t working here.

As summary: i have no vm with enabled HA,also i have no HA-Group and still the fencing is enabled.

How can i disable it ? I don´t need this HA feature at this moment, i just activated it once on a live cluster and want to disable it again.

I tested it with this configuration:

proxmox-ve: 4.0-16 (running kernel: 4.2.2-1-pve)
pve-manager: 4.0-48 (running version: 4.0-48/0d8559d0)
pve-kernel-4.2.2-1-pve: 4.2.2-16
corosync-pve: 2.3.5-1
pve-cluster: 4.0-22
pve-ha-manager: 1.0-9

And also the new Version:

proxmox-ve: 4.1-41 (running kernel: 4.2.8-1-pve)
pve-manager: 4.1-22 (running version: 4.1-22/aca130cf)
pve-kernel-4.2.8-1-pve: 4.2.8-41
pve-kernel-4.2.2-1-pve: 4.2.2-16
corosync-pve: 2.3.5-2
pve-cluster: 4.0-36
qemu-server: 4.0-64
pve-firmware: 1.1-7
pve-ha-manager: 1.0-25

Thank you for any help you can give!

Best regards!
