* build: remove broken and unused _la_LIBADD variableNiels de Vos2015-03-191-1/+0
| | | | | | | | | | | | | | | | | | | While building, the following warning is displayed: xlators/features/arbiter/src/Makefile.am:7: variable `_la_LIBADD' is defined but no program or xlators/features/arbiter/src/Makefile.am:7: library has `_la' as canonical name (possible typo) The _la_LIBADD really seems like a typo, dropping it should not be harmful to anything, except for the warning that will now be gone.

* afr: arbiter xlatorRavishankar N2015-03-195-0/+388
This patch adds the arbiter translator into the tree. This is a server side xlator used for replica 3 volumes. It sits above posix and will be loaded on the 3rd (last) brick of every afr subvolume in a replica 3 configuration. It intercepts inode read/write operations: reads are unwound with ENOTCONN, inode writes are unwound with success without actually passing them down to posix. Metadata operations are allowed to pass through. The CLI for creating a 3 way replica with arbiter is also added but kept disabled (A 'normal' 3 way replica is created instead). 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/ Change-Id: I395b81f49d5da52c466daf5c8518f1bbad9c16fa BUG: 1199985 Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reviewed-on: http://review.gluster.org/9840 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
