tiering: remove the translator from build and glusterd

2018-11-02T02:39:35+00:00

Based on the proposal to remove few features as they are not
actively maintained [1], removing tier translator from the
build. Also make sure there are no regression tests involving
tiering feature are present.

TESTS/TIER: bug-1303028-Rebalance-glusterd-rpc-connection-issue.t

2017-02-23T11:50:21+00:00

PROBLEM: spurious failure of the test.

CAUSE: the function "rebalance_run_time" calculates the total time
the tier has been running for. this being a test case, the run time
of tier can be 0 and when the function adds up zero it results in
zero. and thus it starts to fail.

FIX: Give it some time for the function to add up the values.

core: run many bricks within one glusterfsd process

2017-01-31T00:13:58+00:00

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.

tier : Tier as a service

2017-01-17T04:49:47+00:00

tierd is implemented by separating from rebalance process.

The commands affected:

1) Attach tier will trigger this process instead of old one
2) tier start and tier start force will also trigger this process.
3) volume status [tier] will show tier daemon as a process instead
of task and normal tier status and tier detach status works.
4) tier stop implemented.
5) detach tier implemented separately along with new detach tier
status
6) volume tier volname status will work using the changes.
7) volume set works

This patch has separated the tier translator from the legacy
DHT rebalance code. It now sends the RPCs from the CLI
to glusterd separate to the DHT rebalance code.
The daemon is now a service, similar to the snapshot daemon,
and can be viewed using the volume status command.

The code for the validation and commit phase are the same
as the earlier tier validation code in DHT rebalance.

The “brickop” phase has been changed so that the status
command can use this framework.

The service management framework is now used.
DHT rebalance does not use this framework.

This service framework takes care of :

*) spawning the daemon, killing it and other such processes.
*) volume set options , which are written on the volfile.
*) restart and reconfigure functions. Restart is to restart
the daemon at two points
        1)after gluster goes down and comes up.
        2) to stop detach tier.
*) reconfigure is used to make immediate volfile changes.
By doing this, we don’t restart the daemon.
it has the code to rewrite the volfile for topological
changes too (which comes into place during add and remove brick).

With this patch the log, pid, and volfile are separated
and put into respective directories.

tests/glusterd: Parse the new time format

2016-02-26T01:43:52+00:00

A recent change in cli changed elapsed time format
that broke a test.

This patch will fix the issue with parsing.

glusterd/rebalance: initialize defrag variable after glusterd restart

2016-02-23T05:42:03+00:00

During reblance restart after glusterd restarted, we are not
connecting to rebalance process from glusterd, because the
defrag variable in volinfo will be null.

Initializing the variable will connect the rpc
