glusterd: support for tier volumes 'detach start' and 'detach commit'
These commands work in a manner analagous to rebalancing when removing a brick. The existing migration daemon detects "detach start" and switches to moving data off the hot tier. While in this state all lookups are directed to the cold tier. gluster v detach-tier <vol> start gluster v detach-tier <vol> commit The status and stop cli commands shall be submitted separately.
