This is not possible now. It is advised to use round-robin DNS if you
need a high-available hostname. Gluster should try to connect to the
next IP-address from the DNS reply in case the 1st failed.

It is possible to contribute a patch that accepts additional servers.
Either through a new parameter, or have the hostname string split on
commas. If you want to provide a patch for this, you only need to call
glfs_set_volfile_server() multiple times with different hostnames. This
can be done around
