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.
To edit the entry of storage connection in database, you can use hosted-engine --set-shared-config mnt_options backup-volfile-servers=<server2>:<server3> New hosts added to the cluster will automatically take this. The /etc/ovirt-hosted-engine/hosted-engine.conf needs to be edited only for existing hosts On Wed, Jul 4, 2018 at 4:51 PM Liebe, André-Sebastian

Well, I though this wouldn’t be supported at the moment.
But I seriously doubt changing this in engine’s SQL database will be a
good idea at all, since the way hosted-engine’s configuration is shared across each node (/etc/ovirt-hosted-engine/hosted-engine.conf, /var/lib/ovirt-hsoted-engine-ha, configuration inside hosted-engine’s storage domain: hosted-engine.metadata)
I had hoped hosted-engine or hosted-engine-setup cli could be extended
to support this use case. 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)

unsupported, make backups, use at your own risk etc...
you could update the db if you can't put the storage domain into
maintenance
after that put your hosts into maintenance and out again to remount
find the id of the sd you want to update with:
engine=# select * from storage_server_connections;
ensure you have to correct id, the following should point to the old
mount point:
engine=# select connection from storage_server_connections where
id='<id from output above>';
next update your db
engine=# update storage_server_connections set connection='<your new
mount point' where id='<id from output above>';

Yeah, sorry that doesn’t work.
I can’t set hosted_storage (storage domain where hosted engine runs on)
into maintenance mode to being able to edit it.

You can do it by using "Manage Domain" option from Starage Domain.

The steps roughly would be to put that storage domain in maintenance
then edit/redefine it. You have the option to set gluster mount point options for the redundancy part. No need to set dns round robin.

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)?
