Hi list, I'm looking for an advice how to change the mount point of the hosted_storage due to a hostname change. When I set up our hyperconverged lab cluster (host1, host2, host3) I populated the mount path with host3:/hosted_storage which wasn't very clever as it brings in a single point of failure (i.e. when host3 is down). So I thought adding a round robin dns/hosts entry (i.e. gluster1) for host 1 to 3 and changing the mount path would be a better idea. But the mount path entry is locked in web gui and I couldn't find any hint how to change it manually (in database, shared and local configuration) in a consistent way without risking the cluster. So, is there a step by step guide how to achieve this without reinstalling (from backup)?

The correct way to allow hosted engine to use other available gluster peers in case of failure of the specified peer is to pass the –config-append option during setup as described https://ovirt.org/develop/release-management/features/ sla/self-hosted-engine-gluster-support/ If you want to change that now, then just edit the file /etc/ovirt-hosted-engine/hosted-engine.conf on all hosts and add the following line: mnt_options=backup-volfile-servers=host02:host03 However note that for any new hosted engine deployments, the file has to be manually edited.

I’m willing to help out testing any (manual) procedure to get this implemented (e.g. undeploy hosted-engine on two of three nodes, make changes to hosted-engine.metadata, hosted-engine.conf, start/stop hosted-engine, run SQL commands inside engine) > > > > Sincerely > > André > > > > Von: Renout Gerrits [mailto:mail@renout.nl] > Gesendet: Mittwoch, 4.
