[Gluster-users] Moving Brick between Nodes

we're currently searching for a way to move bricks between (physical)
nodes without copying all data.
We have physical nodes with a connected external disk-enclosure which
contains 5 bricks of 8 drives in raid-6 each (total of 40 drives and
about 220 TB after RAID). If this physical node has a longer lasting
hardware failure or needs replacement I want to connect this enclosure
to a different physical node to quickly re-enable access to this huge
amount of data.
If I'm right there's no "native" way to relocate bricks by simply
renaming them in the layout.
I was thinking about giving each brick a dedicated hostname and IP so
that I can move hostname,ip and brick freely between all servers. A
physical node containing Brick A to E so would have 6 hostnames & IPs:
If I want to move brickE to physB I would simply move the IP + Storage
to this physical node ...
Any downside? Better Ideas? Would this work? Am I missing something?
