syncop: improve scaling and implement more tools

2020-05-30T05:17:12+00:00

The current scaling of the syncop thread pool is not working properly
and can leave some tasks in the run queue more time than necessary
when the maximum number of threads is not reached.

This patch provides a better scaling condition to react faster to
pending work.

Condition variables and sleep in the context of a synctask have also
been implemented. Their purpose is to replace regular condition
variables and sleeps that block synctask threads and prevent other
tasks to be executed.

The new features have been applied to several places in glusterd.

libglusterfs: remove dependency of rpc

2019-08-16T05:37:03+00:00

Goal: 'libglusterfs' files shouldn't have any dependency outside of
      the tree, specially the header files, shouldn't have '#include'
      from outside the tree.

Fixes:
* Had to introduce libglusterd so, methods and structures required
  for only mgmt/glusterd, and cli/ are separated from 'libglusterfs/'
* Remove rpc/xdr/gen from build, which was used mainly so
  dependency for libglusterfs could be properly satisfied.
* Move rpcsvc_auth_data to client_t.h, so all dependencies could
  be handled.

glusterd: create separate logdirs for cluster.rc instances

2019-08-14T03:21:30+00:00

Create a separate logdir for each host instance created by
cluster.rc. This makes it easier to determine the files
belonging to a particular instance.

glusterd/thin-arbiter: Thin-arbiter integration with GD1

2019-06-28T17:30:53+00:00

gluster volume create  replica 2 thin-arbiter 1 : :
: [force]

The changes have been made in a way that the last brick in the bricks list
will be treated as the thin-arbiter.
GD1 will be manipulated to consider replica count to be as 2 and continue creating the
volume like any other replica 2 volume but since thin-arbiter volumes need ta-brick
client xlator entries for each subvolume in fuse volfile, volfile generation is
modified in a way to inject these entries seperately in the volfile for every subvolume.

Few more additions -
1- Save the volinfo with new fields ta_bricks list and thin_arbiter_count.
2- Introduce a new option client.ta-brick-port to add remote-port to ta-brick xlator entry
   in fuse volfiles. The option can be set using the following CLI syntax -
   gluster volume set  client.ta-brick-port 
3- Volume Info will contain a Thin-Arbiter-path entry to distinguish
   from other replicate volumes.

glusterd.h: remove unneeded macros or move them to their users.

2019-06-25T06:44:12+00:00

Some macros were not used, so removed.
Some macros were quite local, so moved to the respective users.
Some macros simplified (removed an allocation here and there)

glusterd-volgen.c: remove BD xlator from the graph

2019-06-18T12:09:09+00:00

The BD xlator was removed some time ago. Remove it from the graph.
We can also remove the caps settings - only the BD xlator
was using it.

Lastly, remove the caps (which only BD was using) and the document
describing the translator.

glusterd: Optimize code to copy dictionary in handshake code path

2019-05-31T14:20:25+00:00

Problem: While high no. of volumes are configured around 2000
         glusterd has bottleneck during handshake at the time
         of copying dictionary

Solution: To avoid the bottleneck serialize a dictionary instead
          of copying key-value pair one by one
