Correct CSV Owner node

In my case not all CSV Lun’s had the right owners, I had 2 LUN’s with only 1 owner. In a cluster every Hyper-v node needs to be an owner of all CSV’s in the cluster, to check this run command below

Get-ClusterSharedVolume -Cluster clustername | Get-ClusterOwnerNode

Output:

To correct it run in a admin powershell:

Set-ClusterownerNode -Cluster "clustername" -Owners "Hyper-v01"," Hyper-v02"," Hyper-v03"," Hyper-v04” -Resource "Cluster Disk 2"

Check it again, et voila!

Performance counters server

Sometimes performance counters are not working.

You can fix this, do the following:

In a admin dos box:

C:\WINDOWS\System32\lodctr /r

To check  which counters are enabled:

lodctr /q

To enable a counter:

lodctr /e:Performance Counters
