cluster/afr: Fail open on split-brain

2017-10-26T18:23:35+00:00

Problem:
Append on a file with split-brain succeeds. Open is intercepted by open-behind,
when write comes on the file, open-behind does open+write. Open succeeds
because afr doesn't fail it. Then write succeeds because write-behind
intercepts it. Flush is also intercepted by write-behind, so the application
never gets to know that the write failed.

Fix:
Fail open on split-brain, so that when open-behind does open+write open fails
which leads to write failure. Application will know about this failure.

feature/posix: Enabled gfid2path by default

2017-08-29T12:52:46+00:00

Enable gfid2path feature by default. The basic
performance tests are carried out and it doesn't
show significant depreciation. The results are
updated in issue.

glusterd: do not create .glusterfs/indices

2017-08-23T13:09:47+00:00

glusterd shouldn't concern itself with creating directories specific to
certain xlators.

The index xlator will now proceed creating './glusterfs/indices' dir
only if the parent '.glusterfs' directory exists, which still fixes the
original problem reported i.e 'volume start force' command shouldn't
create brick path if it doesn't exist (BUG 1457202)

cluster/afr: GFID split-brain resolution with existing CLI

2017-07-18T15:24:54+00:00

Problem:
Currently there is no way for the admin from CLI to resolve gfid
split-brain based on some policy like choice of the brick, mtime
or size.

Fix:
With the existing CLI options based on size, mtime, and choice of
brick, we do lookup on the parent for the specified file. As
part of the lookup, if we find gfid mismatch, we resolve them
based on the policy and return. If the file is not in gfid split-
brain, then we check for the data and metadata split-brain in the
getxattr code path, and resolve if any.

This will work provided absolute path to the file with the CLI
and not with gfid of the file. Hence the source-brick policy
without any file path will also not resolve the gfid split-brain
since it uses the gfid of the files. But it can resolve any other
type of split-brains and skip the gfid mismatch resolution with
the usual error message.

Reverting the change https://review.gluster.org/17290. This patch
resolves the issue.

Fixes gluster/glusterfs#135

cluster/afr: Implement quorum for lk fop

2017-06-19T05:17:29+00:00

Problem:
At the moment when we have replica 3 or arbiter setup, even when
lk succeeds on just one brick we give success to application which
is wrong

Fix:
Consider quorum-number of successes as success when quorum is enabled.

index: Do not proceed with init if brick is not mounted

2017-06-19T05:16:53+00:00

..or else when a volume start force is given, we end up creating
/brick-path/.glusterfs/indices folder and various subdirs under it and
eventually starting the brick process.

As a part of this patch, glusterd_get_index_basepath() is added in
glusterd, who will then use it to create the basepath during
volume-create, add-brick, replace-brick and reset-brick. It also uses this
function to set the 'index-base' xlator option for the index translator.

afr: gfid-mismatch-resolution-with-fav-child-policy.t to bad tests

2017-05-15T12:17:21+00:00

gfid-mismatch-resolution-with-fav-child-policy.t  does a `TEST ls
$M0/f3` (line #170) to trigger healing of a file in gfid split-brain in
a rep-3 volume. But the code to trigger name heal of gfid split-brain
file is not yet there. The test is passing due a lookup/ stat on $M0
which triggers a background entry self heal (which has the code to heal
gfid split-brain files) which may or may not complete the heal before
line 170. If it doesn't, lookup on f3 is failing with EIO.

Add the .t to bad tests until Karthik's patch for CLI based gfid
split-brain resolution fixes name heal also.

cluster/afr: GFID split brain resolution with favorite-child-policy

2017-04-21T00:38:54+00:00

Problem:
Currently the automatic split brain resolution with favorite child policy
is not resolving the GFID split brains.

Fix:
When there is a GFID split brain and the favorite child policy is set to
size/mtime/ctime/majority, based on the policy decide on the source and
sinks. Delete the entry from the sinks and recreate it from the source.
Mark the appropriate pending attributes and resolve the GFID split brain.
When the heal takes place it will complete the pending heals and reset
the attributes.
