glfsheal: Explicitly enable self-heal xlator options

2016-12-16T01:34:03+00:00

Enable data, metadata and entry self-heal as xlator-options so that glfs-heal.c
can heal split-brain files even if they are disabled on the volume via volume
set commands.

cluster/afr: CLI for granular entry heal enablement/disablement

2016-11-29T10:52:25+00:00

        Backport of: http://review.gluster.org/15747
When there are already existing non-granular indices created that are
yet to be healed, if granular-entry-heal option is toggled from 'off' to
'on', AFR self-heal whenever it kicks in, will try to look for granular
indices in 'entry-changes'. Because of the absence of name indices,
granular entry healing logic will fail to heal these directories, and
worse yet unset pending extended attributes with the assumption that
are no entries that need heal.

To get around this, a new CLI is introduced which will invoke glfsheal
program to figure whether at the time an attempt is made to enable
granular entry heal, there are pending heals on the volume OR there
are one or more bricks that are down. If either of them is true, the
command will be failed with the appropriate error.

New CLI: gluster volume heal  granular-entry-heal {enable,disable}

glfsheal: print brick name and path even when brick is down

2016-08-13T02:45:06+00:00

Backport of http://review.gluster.org/#/c/15146/

The xml variant of heal info command does not display brick name when
the brick is down due to a failure to fetch the hostUUID. But the non
xml variant does. So fixed the xml variant to print the remote_host
and remote_subvol even when the brick is down.

heal: Fix incorrect heal info output

2016-05-06T14:26:52+00:00

Problem:
In heterogenous clusters, heal info gives incorrect
outout as "Failed to process entries completely.
Number of entries so far: 0".

This happens when the getxattr on virtual xattr
for /.glusterfs/indices/dirty fails
on older bricks as they do not recognize the xattr.

Fix:
Ignore that error so that heal info doesn't
incorrectly report failure.

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.

glfs/heal: Use encrypted connection in shd

2016-03-24T23:55:00+00:00

When management encryption is enabled, GlusterD
only allows encrypted connections for port 24007.
SHD is trying to fetch it's volfile using an
unencrypted connection.

If /var/lib/glusterd/secure-access is present , i.e.
if management ssl is enabled, use encrypted connection
fecth info from glusterd.

heal: Remove sleep()

2016-02-11T17:05:46+00:00

I wrote this program from a sample gfapi program which had sleep.
I am not sure why this sleep was needed. So removing it now.

Changed tests/bugs/replicate/bug-1190069-afr-stale-index-entries.t
to execute count_sh_entries every second, instead of comparing
same value over and over.
