[ovirt-users] mount options change

Hi, is there any way to change mount options on active storage? I started using my gluster volume in replica 3, arbiter 1 configuration with 10.0.4.11:/vms mount point and mount options backup-volfile-servers=10.0.4.13 I would like to add also 10.0.4.12 as backup volfile as I am on full replica 3 now. Yes, I suppose I can shut down all vms, switch domain to maintenance and then change mount options but is there any other way? For example change it directly in db and then restart all hosts one by one (while vms are running)? Cheers, Jiri
