glusterfs.git/tests/basic/afr/split-brain-heal-info.t, branch v3.10.0 core: run many bricks within one glusterfsd process 2017-02-02T00:54:58+00:00 Jeff Darcy jdarcy@redhat.com 2017-01-31T19:49:45+00:00 83803b4b2d70e9e6e16bb050d7ac8e49ba420893 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.
