edit gluster storage domain
Hello, I need to edit a glusterfs storage domain to add the mount option " backupvolfile-server=SERVER" So when the primary servers IP is not accessible the remaining servers will be used to retrieve data stored on the gluster volume. Right now when I try to edit the storage domain the mount options box is grayed out and not editable. I recently had to take all vms down so I put the HV in maintenance mode and the edit options wasn't present. I need to understand if this is the correct option to make a glusterfs volume fault tolerant? Also I need to understand how to make this edit in the ovirt web interface or other method. TIA

Yes.

You need to put the storage domain in maintenance mode, and then you can edit the gluster mount options. This requires either shutting down all the vms using this storage, or if you cannot afford any downtime, you can live-migrate the disks to another storage domain, edit gluster options, and live-migrate the disks back.

I'm still a bit new to ovirt, so how do I actually put the storage domain into maintenance mode in v3.6.7.5-1? On 08/11/2016 12:38 PM, Nir Soffer wrote:

So I've run into an issue where I add "-obackup-volfile-servers=10.4.16.19:10.4.16.12" to the storage domain object and click ok. Then I get an error that says "Failed to connect Host hv5.domain.com to the Storage Domains SANB". Am I getting the mount option correct? Any thoughts on what I'm doing wrong here?
