glusterd (bitd-svc): fix unused variable warnings/errors

2016-08-29T16:27:59+00:00

http://review.gluster.org/14085 fixes a/the "leak" - via the
generated rpc/xdr headers - of pragmas that mask these warnings.

However 14085 won't pass the smoke test until all the warnings are
fixed.

glusterd: Add async events

2016-08-22T13:10:44+00:00

As the eventing framework is already in the code, this patch targets to capture
all the async glusterd events which are important to be notified to the higher
layers which consume the eventing framework.

I plan to break this work into two different patches where this patch set covers
the first set of events.

glusterd: Stop/restart/notify to daemons(svcs) during reset/set on a volume

2015-08-07T06:22:53+00:00

problem : Reset/set commands were not working properly. reset command returns
success but it not sending notification to svcs if corresponding graph modified.

Fix: Whenever reset/set command issued, generate the temp graph and compare
with original graph and do the fallowing actions
1.) If both graph are identical nothing to do with svcs.
2.) If any changes in graph topology restart/stop service by calling
svc manager.
3)  If changes in options send notify signal by calling glusterd_fetchspec_notify.

glusterd: initialize the daemon services on demand

2015-07-27T07:14:01+00:00

As of now all the daemon services are initialized at glusterD init path. Since
socket file path of per node daemon demands the uuid of the node, MY_UUID macro
is invoked as part of the initialization.

The above flow breaks the usecases where a gluster image is built following a
template could be Dockerfile, Vagrantfile or any kind of virtualization
environment. This means bringing instances of this image would have same UUIDs
for the node resulting in peer probe failure.

Solution is to lazily initialize the services on demand.

features/bitrot: Per volume bitrot translator

2015-05-04T05:17:17+00:00

Currently whatever bitrot/scrubber tunable value user set for one
volume that value is considering for all other volumes also.
Each volume should act on their respective bitrot/scrubber tunable
value.

For handling bitrot/scrubber tunable value independently with respect
to all the volume bitrot and scrubber translator should run seperatly
for each volume.

glusterd: do not pass volinfo in glusterd_svc_manager function

2015-04-30T09:43:59+00:00

On restarting of glusterd first it will start all the bricks present
in the volume then it will start all the services. During starting of
all the services it may pass volinfo as a NULL. It will cause Assert
failure in glusterd_bitdsvc_manager function and will cause a glusterd
crash.

glusterd: bitd daemon should not start on the node which dont have any brick

2015-04-10T10:12:13+00:00

If user enable bitrot from node1 which have brick then glusterd starting
bitd daemon on node1 as well as glusterd starting bitd deamon on another node2
which does not have any brick (node1 and node2 are part of cluster).

With this fix glusterd will not start bitd daemon on the node which
don't have brick.
