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
