Dear oVirt users, I'm currently migrating our gluster setup, so i've done a gluster replace brick to the new machines. Now i'm trying to update the connection strings of the related storage domains including the one hosting the ovirt-engine (which i believe cannot be brought down for maintenance). At the same time i'm trying to disable the "Use managed gluster volume" feature. i've had tested this in a lab setup, but somehow i'm running into issues on the actual setup. On the lab setup it was enough to run a query like this; UPDATE public.storage_server_connections SET "connection"='10.201.0.6:/ovirt-kube',gluster_volume_id=NULL,mount_options='backup-volfile-servers=10.201.0.1:10.201.0.2:10.201.0.3:10.201.0.5:10.201.0.4:10.201.0.7:10.201.0.8:10.201.0.9' WHERE id='29aae3ce-61e4-4fcd-a8f2-ab0a0c07fa48'; on the live setup i also seem to run a query like this; UPDATE public.gluster_volumes SET task_id=NULL WHERE id='9a552d7a-8a0d-4bae-b5a2-1cb8a7edf5c9'; i couldn't really find where this task_id relates to, but it does make the checkbox for "Use managed gluster volume" being unchecked in the web interface. in the lab setup it was enough to run within the hosted engine; - service ovirt-engine restart and then bring an ovirt-host machine to maintenance, and active it again. and the changed connection string was being mounted in the /rhev/data-center/mnt/glusterSD/ directory. Also the vm's after being shutdown and brought up again, started using the new connection string. But now on the production instance, when i restart the engine the connection string is restored to the original values in the storage_server_connections table. I don't really understand where the engine gathers this information from. Any advice on how to actually change the connection strings would by highly appreciated. Thanks Olaf
