[ovirt-users] Re: Q: Get Host Capabilities Failed after restart

I have noticed so far that node14 is serving NFS share which had been marked as problematic (probably because of the downtime during the migration) but it has recovered. In the meantime, is is possible to get some meaningful results when calling: $ vdsm-client Host getStats and $ vdsm-client Host getCapabilities on node14? What is the state for vdsmd service when running systemctl status vdsmd? One other thing to rule out is the networking/firewall. Here the list of the ports to be open for the host (the documentation is for hosted engine, but it applies for standalone setup as well): https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_eng... <https://www.ovirt.org/documentation/installing_ovirt_as_a_self-hosted_eng... btw. I have been hunting for the rare and hard to recreate bug for quite a long time (without success yet) so any reported connectivity issues between the manager and hosts are super interesting to me.
