cluster/afr : Prevent inode-evict during split-brain resolution

2015-05-09T08:54:56+00:00

        Backport of: http://review.gluster.org/#/c/10134/

1) Provided setfattr command to set timeout for split-brain
choice.

2) If split-brain inspection/resolution is being done
from the mount for a file, ref the inode when
split-brain-choice is set.
This inode will be unconditionally unref-ed after timeout
seconds set by the user/default otherwise.

3) Updated the doc and testcase to reflect the changes.

afr: add arbitration support

2015-05-05T09:30:41+00:00

Backport of http://review.gluster.org/#/c/10258/

Add logic in afr to work in conjunction with the arbiter xlator when a
replica 3 arbiter volume is created. More specifically, this patch:

* Enables full locks for afr data transaction for such volumes.
* Removes the upfront marking of pending xattrs at the time of pre-op
  and defer it to post-op. (This is an arbiter independent change and is made for all afr transactions.)
* After pre-op stage, check if we can proceed with the fop stage without
  ending up in split-brain by examining the changelog xattrs.
* Unwinds the fop with failure if only one source was available at the
   time of pre-op and the fop happened to fail on particular source brick.
* Skips data self-heal if arbiter brick is the only source available.
* Adds the arbiter-count option to the shd graph.

This patch is a part of the arbiter logic implementation for 3 way AFR
details of which can be found at http://review.gluster.org/#/c/9656/

cluster/afr : enable inspection & resolution of files in split-brain

2015-03-19T13:33:12+00:00

Part 2/2 patch to enable users analyze and resolve
split-brain.

This patch enables :
1) Users to inspect the files in data and metadata split-brain.
2) Resolve the split-brain.
Both using a series of setfattr commands.

Consider a volume "test" with 2 bricks.

1) To inspect a file f1:
setfattr -n replica.split-brain-choice -v test-client-0 f1
        After the execution of this command, if no read_subvol
is found, reads will be served from test-client-0 (corresponding
to brick-0).

2) To resolve split-brain :
setfattr -n replica.split-brain-heal-finalize -v test-client-0 f1
        Execution of this command will lead to the resolution
of data and metadata split-brain with subvol mentioned in the
command (test-client-0 here) as the source and the rest as sink.

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: When parent and entry read subvols are different, set entry->inode to NULL

2015-02-02T20:07:08+00:00

That way a lookup would be forced on the entry, and its attributes will
always be selected from its read subvol.
