When pre-staging a computer account for HV replica broker does not work
While creating a Hyper-V replica broker in my HV cluster, I came across a problem. No matter what workaround I tried, my broker wont work. I tried pre-staging the computer account etc, as mentioned here but for my particular environment, it did not work. I read this: “https://blogs.technet.microsoft.com/askpfeplat/2012/12/09/why-adding-hyper-v-replica-connection-broker-fails-in-failover-cluster-manager/” and this https://social.technet.microsoft.com/Forums/en-US/36ab7df9-a202-4493-a4a4-57b9cc8370b8/hyperv-replica-broker-stuck-in-failed-status?forum=winserverhyperv Here is how I resolved it : I deleted the pre-staged computer account in AD, (which I had created manually, earlier for the replica broker) Configured the role in FCM, no errors while creation After that… yes, I got errors in the log (ignore for a minute) Then I recreated the AD computer name by hand and gave…

Behavior of CSVs in Hyper-V 2012
I have a few observations about CSVs in a Hyper-V 2012 cluster: 1. Online/Offline status in Disk Management. Take a look at the screenshot below. I was troubled by seeing the CSV offline. I thought there was a problem (not really). Here is how the cluster works: The CSV shows up as an online disk only on the cluster node which is managing is (or is the owner of that CSV). If you change the owner of that CSV to another node, the CSV disk will go offline on this node. However both nodes can still access the CSV via C:\ClusterStorage\vol2 2.

Bypass WSUS to install Windows updates
While trying to setup a Windows 2012 cluster (to be used by Hyper-V) I ran into an issue where the cluster validation tool failed. it said that the MPIO software versions were different on the nodes. Upon searching the net, I found the solution was to install all Windows updates. Unfortunately our WSUS server was not working properly. Every time I would run “Download and install Updates” manually on the Hyper-V Server 2012 (core) using the server configuration screen (no GUI) I would get a message that all updates are already installed. I had to bypass WSUS by running these commands: REG ADD “HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU” /v UseWUServer /t REG_DWORD /d 0…
