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)?

Sincerely

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>'; On Wed, Jul 4, 2018 at 9:13 AM, Liebe, André-Sebastian < andre.liebe@gematik.de> wrote:

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... 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.

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)

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>';
