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.

afr: some coverity fixes

2016-07-28T13:54:49+00:00

Note: This is a backport of http://review.gluster.org/14895.
It contains:
i) fixes that prevent deadlocks (afr-common.c).
ii) fixes over-writing op-errno=ENOMEM with possible other values
(afr-inode-read.c).
iii) prevents doing further operations with a NULL dictionary if
allocation fails (afr-self-heal-data.c).
iv) prevents falsely marking a sink as healed if metadata heal fails
midway(afr-self-heal-metadata.c).
v) other minor fixes.

Considering the above are not trivial fixes, the patch is a good
candidate for merging in 3.8 branch.

Thanks to Krutika for a cleaner way to track inode refs in
afr_set_split_brain_choice().

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.

tests: Self-heald.t spurious failure fix

2016-03-17T06:13:27+00:00

Problem:
There is no guarantee that the indices are created by the time
write is complete because write-behind may not flush the buffers.

Fix:
Disable flush-behind so that by the time 'echo abc > file' completes,
indices are created.

Also removed split-brain-healing.t from spurious failures as we are
not able to recreate it.

tests: Add mechanism for disabled tests

2016-03-10T07:19:40+00:00

Requirements:
Should be able to skip tests from run-tests.sh run.
Should be granular enough to disable on subset of OSes.

Solution:
Tests can have special comment lines with some comma separated values
within them.

Key names used to determine test status are
G_TESTDEF_TEST_STATUS_CENTOS6
G_TESTDEF_TEST_STATUS_NETBSD7
Some examples:
G_TESTDEF_TEST_STATUS_CENTOS6=BAD_TEST,BUG=123456
G_TESTDEF_TEST_STATUS_NETBSD7=KNOWN_ISSUE,BUG=4444444
G_TESTDEF_TEST_STATUS_CENTOS6=BAD_TEST,BUG=123456;555555
You can change status of test to enabled or delete the line only if all the
bugs are closed or modified or if the patch fixes it.

Tests: ls portability regarding dot-files

2015-03-18T10:46:46+00:00

When run as root, BSD ls(1) lists dot-files, which includes
.glusterfs in split-brain-healing.t's usage. This leads to failure.
gfid-self-heal.t suffers the same problem.

Fix by filtering out dot-files in ls(1) output

NB: split-brain-healing.t also requires http://review.gluster.org/9831
to pass on NetBSD.

cluster/afr: split-brain resolution CLI

2015-01-15T09:28:37+00:00

Extend the AFR heal command to include automated split-brain resolution.

This patch [3/3] is the final patch for afr automated split-brain resolution
implementation.

"gluster volume heal  [full | statistics [heal-count [replica
]] |info [healed | heal-failed | split-brain]| split-brain
{bigger-file  |source-brick  []}]"

The new additions being:
1.gluster volume heal  split-brain bigger-file 
Locates the replica containing the FILE, selects bigger-file as source and
completes heal.

2.gluster volume heal  split-brain source-brick 

Selects  present in  as source and completes heal.

3.gluster volume heal  split-brain 
Selects all split-brained files in  as source and completes
heal.

Note:  can be either the full file name as seen from the root of the
volume (or) the gfid-string representation of the file, which sometimes gets
displayed in the heal info command's output.

Entry/gfid split-brain resolution is not supported.

Example can be found in the test case.
