Hello Friends, it’s been a while since my last post. With covid and all my inspiration has not been the best. And with all my spare time going into renovating the house there has not been so much time. But there will be more posts coming soon.

I got the chance to borrow some Lenovo MX1021 Azure Stack HCI nodes to play with and test. And with the soon to be release public preview of 21H2 release i wanted to start getting some real HW experience. So stay tuned for some Azure Stack HCI blog posts coming soon.

So a few weeks ago i was upgrading a 2016 Cluster to 2019. And suddenly the VMM service crashed out of nowhere. I noticed the client had tried to change a VM by increasing the size of the disk. And it failed by loosing connection to the VMM server.

So this week there was a new Cumulative Update out that i wanted to test on a Storage Spaces Direct cluster. But as im using WSUS and VMM to patch my clusters i needed that patch to be in WSUS and it’s not. It will still take a few days before that patch get’s synced to WSUS, and i did not want to manualy update my nodes.

I googled and found a few posts about this but none that was good enough and it took me a while to find something relevant. So i decided i should share with you how you manually ad a Windows Update KB to WSUS.

Hello, a few weeks ago i had some issues at a client where Failover Cluster Manager would not repsond when trying to anything. It would just hang and eventually fail.

Even Hyper-V manager or the normal Powershell tools where hanging and taking forever. Doing a simple Get-VM, Get-Storagejob or any powershell command related to Hyper-V or Storage Spaces Direct would hang for ages, and maybe give out a response after 10-20 min.

Hello Everyone, it’s been a while since my last blog post. So i thought id share something i came over in our Azure Stack HCI(Former S2D) slack channel. https://azurestackhci.slack.com

The reason for this is when the cluster was created, it was run with Enable-ClusterS2D -CacheDeviceModel. When doing so you tell the cluster that the only allowed Cache device is this model.
