Hello Technet,
I have a 6 node Server 2016 S2D Hyper-V cluster running v1607. I am encountering an issue where the cluster pool owner's ram is gradually consumed. I opened a ticket with MS a couple of months back but at the time we did not determine the exact cause of the issue. A reboot fixed the issue, and I closed the ticket without a known resolution. Recently I performed the same task on another node exhibiting the same problem. I have now identified that the cluster pool ownership appears to cause the issue.
Can anyone tell me if this is a known issue, or if there is a fix available? I'll be engaging MS support today to dig into this and will post anything I get back here.
