cluster/dht: Support for hardlink rebalance when decommissioning
The support for hardlink rebalance is only available for decommissioning of a node. this can be triggered in two ways 1. remove-brick start 2. if decommission node value is set in vol file, then a normal rebalance command The way we handle it is- if (nlink > 1) do * if src file doesnt have linkto xattr * mark src's linkto to the dst * else * perform a link on the dst * do a look up * if nlinks = dst.nlinks * migrate data * else * continue crawling done Signed-off-by: shishir gowda <shishirng@gluster.com> Change-Id: If43b5524b872fd1413e9f7aa7f436cb244e30d8d BUG: 763844 Reviewed-on: http://review.gluster.com/2737 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Amar Tumballi <amarts@redhat.com>
