* tests: Fix cleanup routine for some mux testsShyamsundarR2018-08-131-2/+1
| | | | | | | | | | | | | | | | | Some of the mux tests, set a trap to catch test exit and call cleanup. This will cause cleanup to be invoked twice in case the test times out, or even otherwise, as include.rc also sets a trap to cleanup on exit (TERM and others). This leads to the tarballs generated on failures for these tests to be empty and does not aid debugging. This patch corrects this pattern across the tests to the more standard cleanup at the end.

* glusterd: Introduce option to limit no. of muxed bricks per processSamikshan Bairagya2017-07-101-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit introduces a new global option that can be set to limit the number of multiplexed bricks in one process. Usage: `# gluster volume set all cluster.max-bricks-per-process <value>` If this option is not set then multiplexing will happen for now with no limitations set; i.e. a brick process will have as many bricks multiplexed to it as possible. In other words the current multiplexing behaviour won't change if this option isn't set to any value. This commit also introduces a brick process instance that contains information about brick processes, like the number of bricks handled by the process (which is 1 in non-multiplexing cases), list of bricks, and port number which also serves as an unique identifier for each brick process instance. The brick process list is maintained in 'glusterd_conf_t'.

* protocol/server: make listen backlog value as configurableMohammed Rafi KC2017-06-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | problem: When we call listen from protocol/server, we are giving a hard coded valie of 10 if it is not manually given. With multiplexing, especially when glusterd restarts all clients may try to connect to the server at a time. Which will result in overflowing the queue, and kernel will complain about the errors. Solution: This patch will introduce a volume set command to make backlog value as a configurable. This patch also changes the default values for backlog from 10 to 128. This changes is only applicable for sockets listening from protocol. Example: gluster volume set <volname> transport.listen-backlog 1024 Note: 1 Brick has to be restarted to get this value in effect 2 This changes won't be reflected in glusterd, or other xlators which calls listen. If you need, you have to add this option to the volfile.

* trash: fix problem with trash feature under multiplexingJeff Darcy2017-02-091-1/+3
| | | | | | | | | | | | | | | | | | With multiplexing, the trash translator gets a reconfigure call before a notify(CHILD_UP). In this case, priv->trash_itable was not yet initialized, so the reconfigure would get a SEGV. Moving the itable allocation to init seems to fix it, so trash can be reenabled.

* tests: fix online_brick_count for multiplexingJeff Darcy2017-02-071-7/+11
| | | | | | | | | | | | | | | | | | The number of brick processes no longer matches the number of bricks, therefore counting processes doesn't work. Counting *pidfiles* does. Ironically, the fix broke multiplex.t which used this function, so it now uses a different function with the old process-counting behavior. Also had to fix online_brick_count and kill_node in cluster.rc to be consistent with the new reality.

* core: run many bricks within one glusterfsd processJeff Darcy2017-01-301-0/+63
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.
