From 5215766b009f5e38d8915ac0f4d1b0d5603d28e5 Mon Sep 17 00:00:00 2001 From: Jeff Darcy Date: Thu, 8 Dec 2016 16:24:15 -0500 Subject: [PATCH 319/361] core: run many bricks within one glusterfsd process This patch adds support for multiple brick translator stacks running in a single brick server process. This reduces our per-brick memory usage by approximately 3x, and our appetite for TCP ports even more. It also creates potential to avoid process/thread thrashing, and to improve QoS by scheduling more carefully across the bricks, but realizing that potential will require further work. Multiplexing is controlled by the "cluster.brick-multiplex" global option. By default it's off, and bricks are started in separate processes as before. If multiplexing is enabled, then *compatible* bricks (mostly those with the same transport options) will be started in the same process. mainline: > BUG: 1385758 > Reviewed-on: https://review.gluster.org/14763 > Smoke: Gluster Build System > NetBSD-regression: NetBSD Build System > CentOS-regression: Gluster Build System > Reviewed-by: Vijay Bellur (cherry picked from commit 7d2a707973b44b27bcd48bb3fff4209091bb3159) BUG: 1417815 Change-Id: I45059454e51d6f4cbb29a4953359c09a408695cb Signed-off-by: Jeff Darcy Reviewed-on: https://code.engineering.redhat.com/gerrit/101300 Tested-by: Milind Changire Reviewed-by: Atin Mukherjee --- api/src/glfs-mgmt.c | 2 +- glusterfs.spec.in | 1 + glusterfsd/src/Makefile.am | 17 +- glusterfsd/src/gf_attach | 228 ++++++++ glusterfsd/src/gf_attach.c | 247 +++++++++ glusterfsd/src/glusterfsd-mgmt.c | 236 ++++++-- glusterfsd/src/glusterfsd.c | 9 +- libglusterfs/src/client_t.c | 49 +- libglusterfs/src/common-utils.c | 15 +- libglusterfs/src/event-epoll.c | 3 +- libglusterfs/src/event.h | 16 +- libglusterfs/src/globals.h | 2 + libglusterfs/src/glusterfs.h | 7 +- libglusterfs/src/graph.c | 127 ++++- libglusterfs/src/locking.c | 2 +- libglusterfs/src/xlator.c | 72 +++ libglusterfs/src/xlator.h | 8 + rpc/rpc-lib/src/protocol-common.h | 1 + rpc/rpc-lib/src/rpc-clnt.h | 1 -
