This reverts commit b33f3c95ec9c8112e6677e09cea05c4c462040d0.

This commit exposes some issues with management encryption that prevents
GlusterFS from operating properly. This will be added again once
problems with management encryption are fixed.

glusterd: build realpath post recreate of brick mount for snapshot

2016-04-06T04:02:09+00:00

Backport of http://review.gluster.org/#/c/13869

Commit a60c39d introduced a new field called real_path in brickinfo to hold the
realpath() conversion. However at restore path for all snapshots and snapshot
restored volumes the brickpath gets recreated post restoration of bricks  which
means the realpath () call will fail here for all the snapshots and cloned
volumes.

Fix is to store the realpath for snapshots and clones post recreating the brick
mounts. For normal volume it would be done during retrieving the brick details
from the store.

glusterd: fill real_path variable in brickinfo during volume import

2016-04-06T03:30:21+00:00

Variable "real_path" in brick info was used to store absolute path
and using this we check the availability of the newly added bricks.

But we were not populating the variable when we import a volume
from peers. That caused to reset the real_path variable to zero,
which resulted in validation failure for all new brick creation.

afr: add mtime based split-brain resolution to CLI

2016-04-04T17:33:56+00:00

Backport of http://review.gluster.org/#/c/13828/

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.

glusterd: reject peer probe from a reinstalled node

2016-03-24T15:09:02+00:00

Backport of http://review.gluster.org/13519

In a cluster if a node (say N1) goes through a OS reinstallation then probing
some other node in the cluster from N1 doesn't fail as in
gd_validate_mgmt_hndsk_req () uuid & hostname checks are done separately but
there should be one more check where both the conditions should meet.

Steps to create the problem
- N1 probes N2
- bring down glusterd instance on N2
- remove /var/lib/glusterd/* from N2
- restart glusterd instance on N2
- execute gluster peer probe N1 from N2

Validations in gd_validate_mgmt_hndsk_req () has been improved to handle this
special case

libglusterfs: pass buffer size to gf_store_read_and_tokenize function

2016-03-23T20:41:28+00:00

This patch is backport of: http://review.gluster.org/#/c/12346/

Previously if user set an option where length of key=value goes beyond
PATH_MAX (4096) character then tokenzing the option at the time of
reading configuration file will fail.
This is because of the we was having restraction in fgets to read maximum
of PATH_MAX (4096) length of character.
Consequence of this is when user try to restart glusterd, after setting
key=value length beyond PATH_MAX (4096) character, glusterd will not restart.

With this fix instead of PATH_MAX, consumer of gf_store_read_and_tokenize
function will decide the size of the buffer length.
