[ovirt-users] oVirt Node 4.3.2 Activation/Deactivation Loop

I have a two-node cluster with one host (ovirt1) running the oVirt engine and the other running the most recent oVirt Node (4.3.2 from March 2019) software. The engine host has the following information: OS Version: RHEL - 7 - 6.1810.2.el7.centos OS Description: CentOS Linux 7 (Core) Kernel Version: 3.10.0 - 957.12.2.el7.x86_64 KVM Version: 2.12.0 - 18.el7_6.5.1 LIBVIRT Version: libvirt-4.5.0-10.el7_6.9 VDSM Version: vdsm-4.30.13-1.el7 SPICE Version: 0.14.0 - 6.el7_6.1 GlusterFS Version: [N/A] CEPH Version: librbd1-10.2.5-4.el7 Open vSwitch Version: openvswitch-2.10.1-3.el7 Kernel Features: PTI: 1, IBRS: 0, RETP: 1, SSBD: 3 VNC Encryption: Enabled Aside from the other issue I raised of seeing the "Uncaught exception occurred. Please try reloading the page. Details: (TypeError) : Cannot read property 'a' of null Please have your administrator check the UI logs" error on the main host, ovirt1 appears to functioning normally. The node (ovirt2) however is having consistent problems. The follow sequence of events is reproducible and is causing the host to enter a "NonOperational" state on the cluster: * Host ovirt2 installed * VDSM ovirt2 command ConnectStorageServerVDS failed: Message timeout which can be caused by communication issues * Host ovirt2 is not responding. Host cannot be fenced automatically because power management for the host is disabled. * Host ovirt2 cannot access the Storage Domain(s) <UNKNOWN> attached to the Data Center DataCenter1. Setting Host state to Non-Operational. (5/27/1912:43:22 PM) * (Banner appears in GUI) Failed Activating Host ovirt2.witsconsult.com * Failed to connect Host ovirt2 to Storage Pool DataCenter1 (5/27/1912:47:07 PM) * Host ovirt2 cannot access the Storage Domain(s) <UNKNOWN> attached to the Data Center DataCenter1. Setting Host state to Non-Operational. (5/27/1912:47:07 PM) * Host ovirt2 is not responding. Host cannot be fenced automatically because power management for the host is disabled. (5/27/1912:47:07 PM) * VDSM ovirt2 command ConnectStorageServerVDS failed: Message timeout which can be caused by communication issues (5/27/1912:47:07 PM) I can then re-activate ovirt2, which appears as green for approximately 5 minutes and then repeats all of the above issues. What can I do to troubleshoot this?
