[ovirt-users] change self-hosted engine storage domain

Is it possible to change a self-hosted engine's storage domain's settings? I setup a 3-node ovirt + gluster cluster with a dedicated 'engine' storage domain. I can see through the administration portal that the engine storage domain is using a single gluster host and no backup volfile servers. The single gluster host that the engine storage domain settings refer to had to be removed, so now I'm getting issues where VDSM is reporting that it cannot get the volume file information for the engine storage domain. I'm not sure how to go about changing the settings since the only way I've seen how to do this is through the administration portal, which relies on the engine VM (and its storage) being available. What I'd like to do is change the storage domain's path and add mount options for the backup volfile servers.
