I've got a bit of a quandary here. We have several VMs that were powered off about 2 weeks ago. Despite no access being requested, the SYSTEM process is performing large amounts of read activity on the VHD files. Image name is "System, PID is 4, which corresponds to the PID of the hypervisor.
The host is Server 2012 R2 Datacentre edition. We have a 2-node HA cluster and the VHDs reside in ClusterStorage (SAN) as usual. The Failover Cluster Manager still shows the VM role defined. Removing the role from FCM did not seem to have any effect. We do NOT have Replication enabled on any nodes.
2 Questions:
1) How do I tell what is constantly reading these files?
2) How do I make it stop? The high read activity is impacting my cluster performance.
