-o is added by vdsm on the host, try:

backup-volfile-servers=10.4.16.19:10.4.16.12

Re: [ovirt-users] edit gluster storage domain

[Edward Clay]

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?

Re: [ovirt-users] edit gluster storage domain

[Edward Clay]

Thanks for the prompt reply.  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?

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.

[ovirt-users] edit gluster storage domain

[Edward Clay]

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.
