I've added this issue, cause and workaround to an existing bug about re-connection issues with encrypted connections in glusterfs [1]. tl;dr: This happens because the GlusterFS rpc layer is configured in 3.8 to use AF_UNSPEC getaddrinfo(), which returns both IPv6 and IPv4 addresses. Most systems are configured to return IPv6 addresses with a higher priority. GlusterD doesn't listen on IPv6 addresses yet (only on 0.0.0.0). So the initial connection attempt to glusterd fails. Encrypted connections have issues right now, that prevent reconnections with the next addresses (IPv4 mostly) from happening. The daemons fail to start, because they cannot connect to glusterd to get volfiles. This doesn't happen with non-encrypted connections because reconnection works properly. 2 workarounds, - Increase preference for IPv4 addresses in getaddinfo by editing /etc/gai.conf Or, - Edit /etc/hosts and remove IPv6 entry for localhost ~kaushal [1] https://bugzilla.redhat.com/show_bug.cgi?id=1333317#c11 > My environment is: > > Debian Jessie, "LATEST" glusterfs repository > > On each
