Unexpected Large Page File Troubleshooting

This week one of my colleagues has been performing updates on our hypervisor hosts including those running Hyper-V. During this work we received alerts from our monitoring system to indicate two of the hosts had essentially run out of disk space, obviously a little worrying. We stopped the update process while troubleshooting was carried out … Read more

Set Cluster Log Size and Verbosity in Microsoft Server 2008 R2

Recently a critical cluster system had a bit of a hiccup wherein the SQL resource failed between nodes a few times and then gave up.

At work I run both ESXi and Hyper-V, there are certainly … Read more

PowerShell Direct over Hyper-V VMBus

Today I learnt a little about an awesome feature which I think isn’t that well known – or at least when I speak to colleagues past and present they are not familiar with it. The feature in question is leveraging PowerShell on a Hyper-V host down the VMBus to a guest virtual machine. What exactly … Read more

HPE CLX Error – Socket connection timed out to port 2550

This week I came across an interesting problem on one of our Microsoft Failover Clusters (FOC) which utilises the HPE Cluster Extensions (CLX) software to  provide failover support with our HPE 3PAR arrays. A couple of roles within one FOC showed the CLX resource as failed with everything else still showing as online. We were … Read more
