[ovirt-users] Standalone Gluster Storage

[Artem Tambovskiy]

Hi,

I just updated almost all storage domains with backup-volfile-servers mount
options, the last one remaining is the hosted_storage domain which serves
hosted engine VM. I wonder if this domain also needs to be configured
with  backup-volfile-servers
option? If so how to do this - I can't put this domain on maintenance via
web UI.

Regards,
Artem
