Hi,
I have newly deployed, 3 node, Windows 2016 (Build 2724) Hyper-Converged Hyper-V/S2D cluster which is operating normally. The intention is to use DPM 2016 LTSB UR6 to perform VM level backups hosted on the cluster.
After deploying the DPM agents (5.0.375.0) to the cluster nodes, i've started to see cluster errors generated when rebooting a node, CSV auto pause errors for each CSV in the cluster:
"CSVName has entered a pause state because of 'STATUS_UNEXPECTED_NETWORK_ERROR (c00000c4)"
When rebooting a node, there are no backup jobs running, if I remove the DPM agents the nodes reboot without error.
Also, it may be a red herring, but there are entries in the cluster logs generated during a node reboot that relate to an error closing a file named ' DpmFilterTrace.txt' which is stored on the CSVs. Not sure if this is normal or an indication of an issue.
Would appreciate any input from people protecting workloads on HCI clusters using DPM.
Thanks in advance,
James
