glusterd/snapshot: Add a warning message when a volume config changes

2020-03-12T11:27:16+00:00

While changing a volume configuration, there is a chance that the
brick layout on the disk might be changed. If snapshot is present
on such volumes that will effects it's working. So this patch adds
a warning message if snapshot is present while a volume config change
happen.

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.

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    |
                     -----------------------
                    /           |           \
                   /            |            \
              ------------   ------------  ------------

libglusterfs: Move devel headers under glusterfs directory

2018-12-05T21:47:04+00:00

libglusterfs devel package headers are referenced in code using
include semantics for a program, this while it works can be better
especially when dealing with out of tree xlator builds or in
general out of tree devel package usage.

Towards this, the following changes are done,
- moved all devel headers under a glusterfs directory
- Included these headers using system header notation <> in all
code outside of libglusterfs
- Included these headers using own program notation "" within
libglusterfs

This change although big, is just moving around the headers and
making it correct when including these headers from other sources.

This helps us correctly include libglusterfs includes without
namespace conflicts.

glusterd: Introduce daemon-log-level cluster wide option

2018-07-03T14:29:33+00:00

This option, applicable to the node level daemons can be very helpful in
controlling the log level of these services. Please note any daemon
which is started prior to setting the specific value of this option (if
not INFO) will need to go through a restart to have this change into
effect.

glusterd: Fix for shd not coming up

2018-06-13T15:34:08+00:00

Problem: After creating and starting n(n is large) distribute-replicated
volumes using a script, if we create and start (n+1)th distribute-replicate
volume manually self heal daemon is down.

Solution: In glusterd_proc_stop after giving SIGTERM signal if the
process is still running, we are giving a SIGKILL. As SIGKILL will
not perform any cleanup process, we need to remove the pidfile.
