Windows Server 2012 Failover Cluster Hyper-V

[oby]

Hi,

we have a problem with our Windows 2012 Hyper-V Cluster. On the node which does not own the CSV we get event log errors "disk id 153 - the io operation at logical block address .... was retried." everytime a vm needs to write to the csv disk. On the node which owns the CSV there are no problems. After some time the VMs are failing over to the node with the CSV.

We followed the HP best practice.

HW: HP BL460C G7

Any ideas? The error does not occur on an Windows 2008 R2 Hyper-V Cluster.

Thank you.

I have the same problem and others because the connection is lost with storage and from time to time appears ntfs error events. I have opened a support case and recommended to apply these KB
