@atinmu Haven't a clue about IPv6, and I'm working on the disk storage/provisioning stuff.

It would be good to ensure that glusterd works fine in dual homed systems that have a combination of IPv4 and IPv6 addresses. I have heard some feedback about glusterd (gd1) operations not working well when both IPv4 and v6 are used for building the trusted storage pool.

Seeing this error running the glusterd2 kubernetes recipes. Is this possibly ipv6 related ?
