Well, if it's officially supported, that could be a really interesting
option to quickly scale big storage systems.
I'm thinking about our scenario: 3 servers, 36 12TB disks each. When
adding a new server (or another pair of servers, to keep an odd number)
it will require quite a lot of time to rebalance, with heavy
implications both on IB network and latency for the users. If we could
simply swap around some disks it could be a lot faster.
Have you documented the procedure you followed?
