Hi Christian, The following procedure should provide the solution: 1. set the storage domain to maintenance (via webadmin UI, for example) 2. copy/sync the contents of the storage domain including the metadata, to ensure that data in both locations (the old and the new mount points) is the same. 3. run modification query on ovirt engine database (please replace the values 'yournewmountpoint' and 'therelevantconnectionid' with the correct ones: UPDATE storage_server_connections SET connection='yournewmountpoint' WHERE id='therelevantconnectionid'; 4. There is a bug related to storage domain caching in VDSM (host) , so it needs to be workarounded by restarting vdsm (service name is 'vdsmd') 5. activate storage domain (via webadmin UI, for example). Please also note that starting version 3.3 there's a new possibility allowing to edit the mount point via webadmin UI and REST api: http://www.ovirt.org/Features/Manage_Storage_Connections ----- Original Message -----

I need to change the storage domain mount point due to some changes in our infrastructure. I have found the area's I believe will be required:
DB: engine; table: storage_server_connections; change the connection path field on the NFS mount point: change the path data in <UUID>/dom_md/metadata
Is there anywhere else I will need to change this? I know that this is not a supported change but it's either that or we export every VM we have running which would take about a week to complete or we rename the mount and change the path. Is there another option?
Current running version: 3.1.0-2.fc17
Thanks
