*	core: run many bricks within one glusterfsd process	Jeff Darcy	2017-01-30	1	-0/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	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.

*	glusterd: Don't allow remove brick start/commit if glusterd is down of the ↵	Atin Mukherjee	2015-08-26	1	-0/+54
	host of the brick remove brick stage blindly starts the remove brick operation even if the glusterd instance of the node hosting the brick is down. Operationally its incorrect and this could result into a inconsistent rebalance status across all the nodes as the originator of this command will always have the rebalance status to 'DEFRAG_NOT_STARTED', however when the glusterd instance on the other nodes comes up, will trigger rebalance and make the status to completed once the rebalance is finished. This patch fixes two things: 1. Add a validation in remove brick to check whether all the peers hosting the bricks to be removed are up. 2. Don't copy volinfo->rebal.dict from stale volinfo during restore as this might end up in a incosistent node_state.info file resulting into volume status command failure.
