cluster/dht: Rebalance will be a new glusterfs process
rebalance will not use any maintainance clients. It is replaced by syncops, with the volfile. Brickop (communication between glusterd<->glusterfs process) is used for status and stop commands. Dept-first traversal of dir is maintained, but data is migrated as and when encounterd. fix-layout (dir) do Complete migrate-data of dir fix-layout (subdir) done Rebalance state is saved in the vol file, for restart-ability. A disconnect event and pidfile state determine the defrag-status Signed-off-by: shishirng <shishirng@gluster.com> Change-Id: Iec6c80c84bbb2142d840242c28db3d5f5be94d01 BUG: 763844 Reviewed-on: http://review.gluster.com/2540 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Amar Tumballi <amarts@redhat.com>
