VHDX files not removed after storage move

Sometimes after doing a storage move in SCVMM 2012 the source will not be removed from the CSV LUN after completion.

Not always but sometimes you will get the following message:

 

As the warning states you have to manually delete the contents, but if you delete the VHDX file it will be gone but after hitting f5 the file is still there.

There are some people saying you have to change the owner of the CSV disk and delete the files on the owner node of the CSV.

 

But there is a simpler way to delete the files. Just rename the folder where the files are located, normally is this like c:\clusterstorage\volumex\servername\

So just rename the folder servername to servernameold, then go 1 folder up to volume 1 and go back, et voila the files are gone!

Hyper-V 2012 Hotfixes voor een stabiel cluster

Op onderstaande website worden alle hotfixes opgesomd die nodig zijn voor een stabiel Hyper-V cluster:

Wij hebben ook diverse problemen gehad, vooral m.b.t. Lun's die verdwenenen tijdens het backuppen van virtuele machines middels DPM, de VM's op deze lun gingen vervolgens offline en kwamen niet meer up.
uiteindelijk hebben we ODX disabled op de host nodes en tot op heden hebben we geen problemen meer!

Disable ODX

---

To establish a baseline of non-offloaded data transfer performance, first disable ODX on the server by following these steps:

To disable ODX on the server

---

1. Open a Windows PowerShell session as an administrator.
2. Check whether ODX is currently enabled (it is by default) by verifying that the FilterSupportedFeaturesMode value in the registry equals 0. To do so, type the following command:
   Get-ItemProperty hklm:\system\currentcontrolset\control\filesystem -Name "FilterSupportedFeaturesMode"
   

3. Disable ODX support. To do so, type the following command:
   Set-ItemProperty hklm:\system\currentcontrolset\control\filesystem -Name "FilterSupportedFeaturesMode" -Value 1
