Was this issue solved?
Because we’re experiencing also issues with McAfee Enterprise 8.7 on a 4-node Hyper-V cluster. Sometimes CSV is not accessible and System log returns error containing ERROR_TIMEOUT(1460). Disabling McAfee did not help, only uninstall fixed the problem (CSV accessible from all 4 nodes). Testing now with latest version...8.7 with patch 4, but it doesn't look good (simple browse to folder under c:\clusterstorage does not work)
Patch 4 does seem to have solved our problem; the most definite symptom we had was an event 5120 ( STATUS_CONNECTION_DISCONNECTED) in the windows system event log. Our problem was specifically with iSCSI storage. We did also sometimes see the 1460 in conjunction with the 5120. We received a suggestion from MS at the time to consider installing this MS fix
BUT that's probably only relevant with iSCSI storage.
