W2K12 Hotfix related to Host Level Backup of VMs
Feb 15th
[UPDATE 1/15/2013]: See problems reported after installing this hotfix at end of this forum post. I have opened a line with the product team to find out what is going on
[UPDATE 2/15/2013]: We are now exactly 1 month after I warned you to be very careful with installing http://support.microsoft.com/kb/2799728/en-us as it caused a severe memory leak. If you have followed the forum post mentioned above, you will have gathered that Microsoft has worked feverishly to get on top of the problem. Mike Jacquet who has been very communicative about this issue, has today confirmed that a fix is now code complete, has been fully tested and is only waiting for the KB article to be written.
The memory leak was caused by a fault found in the CSV filter driver (CSVFLT.sys). When the fix arrives (any time now), you can simple install it whether you have applied the hotfix mentioned in this blog or not. The original kb article will be superseded by this one.
[UPDATE 2/17/2013]: The hotfix is available from http://support.microsoft.com/kb/2813630/en-us
[UPDATE 2/18/2013]: If you are still seeing a problem, take a look at this (which is an excerpt from the forum post mentioned above:
“Cluster Shared Volume ‘Volume2′ (‘ClusterStorage Volume 2′) is no longer available on this node because of ‘STATUS_CLUSTER_CSV_AUTO_PAUSE_ERROR(c0130021)’. All I/O will temporarily be queued until a path to the volume is reestablished.
STATUS_CLUSTER_CSV_AUTO_PAUSE_ERROR is generated when csvfs filter attempts to retrieve the Copy On Write bitmap for a snapshot volume that has been cleaned up. This error is most likely occurring on large scale hyper-v deployments and is one of the issues we discover after fixing other scale out problems addressed in the V2 fix. Due to ongoing long haul testing required to be done, we did not want to hold up V2 of the fix that we just released, so the Windows group will release a more compressive V3 patch a little later to address that and other issues found during large scale testing.
For any customers still experiencing the same symptoms as outlined in KB2813630 after installing the fix, please check binary versions on all nodes.

Recommended post W2K8R2 SP1 Clustering and Hyper-V Hotfixes
Jan 12th
LAST UPDATE: 12-01-2012
One of the visitors of this blog asked the question if we could publish a list of recommended post Windows Server 2008 R2 SP1 hotfixes related to either Clustering or Hyper-V. Well here it is!
For a complete overview of what was rolled-up in SP1 take a look at the Excel sheet (Updates in Win7 and WS08R2 SP1.xls) which can be found on here.
Note I. Microsoft will release hotfixes if an issue occurs that needs to fixed before releasing a roll-up update or a service pack. However, the hotfix in question is intended to correct only the problem that is described in the article. Apply the hotfix only to systems that are experiencing the problem that is described in the articles. The hotfix might receive additional testing. Therefore, if you are not severely affected by this problem, we recommend that you wait for the next software update that contains this hotfix.
Note II. Updates can be applicable to Windows Server 2008 R2 (RTM) and/or Windows Server 2008 R2 SP1.
First troubleshooting step for a lost (CSV) disk in Hyper-V cluster
Aug 18th
Update October 21st, 2011 (see bottom)
Let’s assume the following scenario:
- You have a Hyper-V R2 SP1 cluster that has three or more nodes
- You are using Cluster Shared Volumes
- You learnt about the Cluster Validation problem that was solved by KB2531907 back in May 2011, which prevented the “Failed to get SCSI page 83h VPD descriptors for cluster disk <number> from node <node name> status 2” error after running the Validate SCSI Vital Product Data. It also solved the “Disk with identifier <value> has a Persistent Reservation on it. The disk might be part of some other cluster. Removing the disk from validation set” error when running the List Potential Cluster Disks test. The hotfix resolves an issue in which the storage test incorrectly runs on disks that are online and not in the Available Storage group. The problem can also be caused by other issues such as storage problems or an incorrect configuration which means you have to check your storage configuration and check related events on your Hyper-V hosts.
- You want to add more capacity and add a new Hyper-V host.

HP Integration Note for HP ProLiant and Windows Server 2008 R2 SP1
May 12th
Many of us have delayed installing Windows Server 2008 R2 SP1 on HP ProLiant Servers until guidance from HP became available. While writing my blogpost Preparing for upgrading your Hyper-V R2 cluster to SP1 about two months ago I was unable to find any details. Searching for an updated BladeSystem Matrix Compatibility guide, I stumbled upon the long expected HP Integration Note: Implementing Microsoft Server 2008 R2 Service Pack 1 on HP ProLiant and Integrity servers.

Hotfixes in the post SP1 era
Apr 26th
Several hotfixes have been issued after the formal release of Windows Server 2008 R2 SP1. There was one particular hotfix in the making that we have really been waiting for. Many enthusiastic installers of SP1 in Hyper-V clusters with 3 or more nodes would face a problem with Cluster Validation. See the thread for more details.
We are glad that the hotfix has been made available today:
