[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?
