glusterd: populate brickinfo->real_path conditionally

2016-04-11T18:39:16+00:00

glusterd_brickinfo_new_from_brick () is called from multiple places and one of
them is glusterd_brick_rpc_notify where its very well possible that an
underlying brick's file system has crashed and a disconnect event has been
received. In this case glusterd tries to build the brickinfo from the brickid in
the RPC request, however the same fails as glusterd_brickinfo_new_from_brick ()
fails from realpath.

Fix is to skip populating real_path if its a disconnect event.

afr: add mtime based split-brain resolution to CLI

2016-03-29T19:08:35+00:00

Extended the CLI to include support for split-brain resolution based on
mtime. The command syntax is:

$:gluster volume heal  split-brain latest-mtime 

where  can be either the full file name as seen from the root of the
volume (or) the gfid-string representation of the file.

2016-02-22T12:01:11+00:00

 # gluster volume start [force] command its starting the volume.

With this patch if server side quorum is not met then it will
prevent starting of the volume.

glusterd: Bug fixes for IPv6 support

2016-02-20T17:16:42+00:00

Problem:
Glusterd not working using ipv6 transport. The idea is with proper glusterd.vol configuration,
1. glusterd needs to listen on default port (240007) as IPv6 TCP listner.
2. Volume creation/deletion/mounting/add-bricks/delete-bricks/peer-probe
   needs to work using ipv6 addresses.
3. Bricks needs to listen on ipv6 addresses.
All the above functionality is needed to say that glusterd supports ipv6 transport and this is broken.

Fix:
When "option transport.address-family inet6" option is present in glusterd.vol
file, it is made sure that glusterd creates listeners using ipv6 sockets only and also the same information is saved
inside brick volume files used by glusterfsd brick process when they are starting.

Tests Run:
Regression tests using ./run-tests.sh
    IPv4: Ran manually till tests/basic/rpm.t .
    IPv6: (Need to add the above mentioned config and also add an entry for "hostname ::1" in /etc/hosts)
        Started failing at ./tests/basic/glusterd/arbiter-volume-probe.t and ran successfully till here

Unit Tests using Ipv6
    peer probe
    add-bricks
    remove-bricks
    create volume
    replace-bricks
    start volume
    stop volume
    delete volume

tier/glusterd: Check before starting tier daemon during volume start

2015-12-09T07:16:53+00:00

We start tier daemon when volume is started without looking into the
previous status. The problem with that if detach-tier is started
and then volume force start is actually starting tier daemon.

This is also fixes a problem where tier daemon is not starting
after detach stop.

glusterd: Change volume start into v3 framework

2015-11-25T12:10:34+00:00

As part of volume start, if the volume is of tier type
then we need to start tiering daemon also. But before
starting tier daemon all the bricks should be started.

So by changing volume start into v3 framework, we can
do tier start in post validate phase
