quota: start aux mount from glusterd with inet address
With below patches, quota aux mount now uses unix domain socket to connect to glusterd http://review.gluster.org/#/c/12645/ http://review.gluster.org/#/c/12819/ When USS is enabled, snapd protocol client tries to connect to glusterd with inet and fails, because remote-host option by client process is set to UDS file This patch starts the aux client process from glusterd with inet address Change-Id: I6967043bfd8824658ea39bfd2842591fcc3280fd BUG: 1299497 Signed-off-by: vmallika <vmallika@redhat.com> Reviewed-on: http://review.gluster.org/13255 Smoke: Gluster Build System <jenkins@build.gluster.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Atin Mukherjee <amukherj@redhat.com> Reviewed-by: Raghavendra G <rgowdapp@redhat.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org>
