Mounting a Red Hat Storage Volume over the GlusterFS-native protocol fails due to DNS resolution issues

Issue

A volume created on a trusted pool can not be mounted through the GlusterFS-native protocol, mounting through NFS works

In the log from the glusterfs client (/var/log/glusterfs/$mountpoint.log) the following messages appeared:

 E [common-utils.c:125:gf_resolve_ip6] 0-resolver: getaddrinfo failed (Name or service not known)
