afr: arbiter xlator
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 Change-Id: I395b81f49d5da52c466daf5c8518f1bbad9c16fa BUG: 1199985 Signed-off-by: Ravishankar N <> Reviewed-on: Tested-by: Gluster Build System <> Reviewed-by: Pranith Kumar Karampuri <> Reviewed-by: Vijay Bellur <>
