Hello All,

Every few days we receive the following message from our Hyper-V Cluster.

Cluster Shared Volume 'disk 1' ('disk 1) has entered a paused state because of '(c000020c)'. All I/O will temporarily be queued until a path to the volume is reestablished.Cluster Shared Volume 'disk 1' ('disk 1') has entered a paused state because of '(c000020c)'. All I/O will temporarily be queued until a path to the volume is reestablished.

We are running on Windows 2012R2 with all the patches till 01-05-2015.

All the VM's off the CSV volume stay online and there are no interruption within the VM's. Anybody a idee how ik can solve the message. 

This can be caused by VSS pausing the I/O when preparing snapshot. If you have a backup job (or any other activity that can trigger creation of a snapshot) configured to run at the time this error is logged, then you can safely ignore it.
