mgmt/shd: Implement multiplexing in self heal daemon

2019-04-01T03:44:23+00:00

Problem:

Shd daemon is per node, which means they create a graph
with all volumes on it. While this is a great for utilizing
resources, it is so good in terms of performance and managebility.

Because self-heal daemons doesn't have capability to automatically
reconfigure their graphs. So each time when any configurations
changes happens to the volumes(replicate/disperse), we need to restart
shd to bring the changes into the graph.

Because of this all on going heal for all other volumes has to be
stopped in the middle, and need to restart all over again.

Solution:

This changes makes shd as a per volume daemon, so that the graph
will be generated for each volumes.

When we want to start/reconfigure shd for a volume, we first search
for an existing shd running on the node, if there is none, we will
start a new process. If already a daemon is running for shd, then
we will simply detach a graph for a volume and reatach the updated
graph for the volume. This won't touch any of the on going operations
for any other volumes on the shd daemon.

Example of an shd graph when it is per volume

                           graph
                     -----------------------
                     |     debug-iostat    |
                     -----------------------
                    /         |             \
                   /          |              \
              ---------    ---------      ----------
              | AFR-1 |    | AFR-2 |      |  AFR-3 |
              --------     ---------      ----------

A running shd daemon with 3 volumes will be like-->

                           graph
                     -----------------------
                     |     debug-iostat    |
                     -----------------------
                    /           |           \
                   /            |            \
              ------------   ------------  ------------
              | volume-1 |   | volume-2 |  | volume-3 |
              ------------   ------------  ------------

build: do not #include "config.h" in each file

2015-05-29T12:43:17+00:00

Instead of including config.h in each file, and have the additional
config.h included from the compiler commandline (-include option).

When a .c file tests for a certain #define, and config.h was not
included, incorrect assumtions were made. With this change, it can not
happen again.
