glusterd: socketfile & pidfile related fixes for brick multiplexing feature
Problem: While brick-muliplexing is on after restarting glusterd, CLI is not showing pid of all brick processes in all volumes. Solution: While brick-mux is on all local brick process communicated through one UNIX socket but as per current code (glusterd_brick_start) it is trying to communicate with separate UNIX socket for each volume which is populated based on brick-name and vol-name.Because of multiplexing design only one UNIX socket is opened so it is throwing poller error and not able to fetch correct status of brick process through cli process. To resolve the problem write a new function glusterd_set_socket_filepath_for_mux that will call by glusterd_brick_start to validate about the existence of socketpath. To avoid the continuous EPOLLERR erros in logs update socket_connect code. Test: To reproduce the issue followed below steps 1) Create two distributed volumes(dist1 and dist2) 2) Set cluster.brick-multiplex is on 3) kill glusterd 4) run command gluster v status After apply the patch it shows correct pid for all volumes BUG: 1444596 Change-Id: I5d10af69dea0d0ca19511f43870f34295a54a4d2 Signed-off-by: Mohit Agrawal <moagrawa@redhat.com> Reviewed-on: https://review.gluster.org/17101 Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Prashanth Pai <ppai@redhat.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Atin Mukherjee <amukherj@redhat.com>
