<div>Hi there, first of all thank you both for your suggestions and observations and apologies for my late reply.</div>
<div><br>
</div>
<div>I will check the logs on both hosts (although only one of them seems to be the issue) and will revert with any findings.</div>
<div><br>
</div>
<div>Just to confirm the error message for the monitor operation:</div>
<div><br>
</div>
<div>It seems that host zc-mail-2.zylacloud.com has a connection timeout to monitor the resource fence_zc-mail-1_virsh right?</div>
<div><br>
</div>
<div>My question here is, what is the monitor operation doing to confirm that the monitor operation is successful?</div>
<div><br>
</div>
<div>Is it doing the same operation as specified in the stonith resource and expecting a particular exit code?</div>
<div><br>
</div>
<div>Thanks once again</div>
<div><br>
</div>

<pre>Hello users, I would like to ask for assistance on the below setup</pre>
<pre>please, mainly on the monitor fence timeout:</pre>

<pre>I notice that the issue happens at 00:00 on both days .</pre>
<pre>Have you checked for a backup or other cron job that is 'overloading'</pre>
<pre>the virtualization host ?</pre>
<pre></pre>
<pre><br></pre>
<pre>This is a very good point. I had a similar problem with a vsphere </pre>
<pre>cluster. Two hyper-converged storage appliances. I used the </pre>
<pre>fence-vmware-rest (or soap) stonith agent to fence the storage apps. </pre>
<pre>Worked just fine. Until the vcenter server appliance got busy doing </pre>
<pre>something or other. Next thing I know, I'm getting stonith agent </pre>
<pre>timeouts. I ended up switching to fence_scsi. Not sure there is a good </pre>
<pre>answer. I saw on a vmware forum a recommendation to increase the </pre>
<pre>stonith timeout, but the recommended timeout was close to a minute, </pre>
<pre>which is enough to be a problem for the VMs in that cluster...</pre>
