csquire commented on issue #2890: KVMHAMonitor thread blocks indefinitely while NFS not available URL: https://github.com/apache/cloudstack/issues/2890#issuecomment-433081781 When you block NFS on a host, eventually all the agentRequest-Handler and UgentTask threads gradually hang as well. It seems after the last UgentTask handler thread hangs, is about the time the host is marked as Down.

csquire commented on issue #2890: KVMHAMonitor thread blocks indefinitely while NFS not available URL: https://github.com/apache/cloudstack/issues/2890#issuecomment-428282173 After performing more tests, virtlockd does help prevent from getting duplicate VMs. With Host HA disabled, the blocked host goes to a `Down` state but the VMs continue to run on the blocked host and new ones don't start on other hosts because of the lock on the root disk. But, if Host HA *is* enabled, the blocked host gets rebooted because of the bug above. The VMs on the host get rescheduled on that same host when it comes up, but it still should not have been rebooted because of blocked NFS. This is an automated message from the Apache Git Service.
