I have Windows 2008R2 Hyper-V cluster running 3 nodes. About 10 hosts are running at the moment. I am getting event ID 5120 and 1127. I had this issue before but I restarted my nodes and these errors disappeared.
I have recently one of the node had issues and it restarted all the hosts. I found out that Quorum network failed and one of the clustered disk is no longer available.
so I moved all the VM's from this node and restarted. Since then there is no disruption in running the VM's. However, I am still getting these two events 5120 and 1127.
I could not find any specific error. I believe this error started when I started using one of the VM which was on but not being used. Also things got worst when it was running the backups of Hyper-v.
Still I am getting few errors after 2-3 hours. Will appreciate if there is any hyper-v experts available who know this kind of error problem.
Thanks in advance
