glusterfs.git/extras, branch v4.0.0

build: add --without-server option

2018-02-21T18:08:14+00:00

With Gluster 4.0 we will not provide the server components for EL6 and
older. At one point Gluster 4.x will get GlusterD2, which requires
Golang tools in the distribution. EL6 does not contain these at the
moment.

With this change, it is possible to `./configure --without-server` which
prevents building glusterd and the xlators for the bricks. Building RPMs
can pass `--without server` and the glusterfs-server sub-package will
not be created.

tests: Enable geo-rep test cases

2018-01-05T07:08:10+00:00

This patch re-enables the geo-rep test cases.
Along with it does following optimizations.

1. Use EXPECT_WITHIN instead of sleep
2. Clean up geo-rep ssh key after test
3. Changes to gverify.sh and S56glusterd-geo-rep-create-post.sh
   to use the given ssh identity file for geo-rep create
4. Make gluster-command-dir configurable and introduce
   slave-gluster-command-dir which points the parent directory
   of gluster binaries in master and slave respectively.

extras: scripts to control CPU/MEMORY for any gluster daemon during runtime

2017-11-13T11:07:06+00:00

Problem: Sometime gluster daemons like glustershd can consume a lot of cpu and/
or memory if there is a large amount of data/ entries to be healed.

Solution: Until we have some form of throttling/ QoS mechanisms built into
gluster, we can use control groups for regulating cpu and memory of any gluster
daemon using control-cpu-load.sh and control-mem.sh scripts respectively.

Test:    To test the control-cpu-load.sh script follow below procedure:
         1) Setup distribute replica environment
         2) Selfheal daemon off
         3) Down one node from replica nodes
         4) Create millions of files from mount point
         5) Start down node
         6) Check cpu usage for shd process in top command
         7) Run script after provide shd pid with CPU quota value
         8) Check again cpu usage for shd process in top command

Note: control-mem.sh script can cap the memory usage of the process to the set
limit, beyond which the process gets blocked. It resumes either when the memory
usage comes down or if the limit is increased.

extras/hooks: Honour all input arguments to scripts

2017-10-31T12:24:05+00:00

Some of the hook scripts were not honouring the arguments with which
they are invoked during various volume operations. So make sure that
we consider everything while parsing the command line arguments to
avoid following warnings:

. . .
ame: unrecognized option '--first=no'
ame: unrecognized option '--version=1'
ame: unrecognized option '--volume-op=start'
. . .

extras/hooks: Fix getopt usage

2017-10-30T15:49:02+00:00

`getopt` does not have an optional argument as '-name'. It should
be either '-n' or '--name'(see man getopt(1)). This wrong usage
resulted in setting the script name as 'ame' instead of $PROGNAME
in most of the hook-scripts.

Additionally the following line from DESCRIPTION given for `getopt`
shell command expects short options for almost every kind of usage
mentioned in SYNOPSIS:

. . .
If  no  '-o'  or '--options' option is found in the first part, the
first parameter of the second part is used as the short options string.
. . .

Refer http://man7.org/linux/man-pages/man1/getopt.1.html for more
clarity on its usage.
