Do I understand correctly:
gluster peer attach would attach the probing server into the pool it
is probing, correct?
If so, and if it is already a member of a pool, could you join two
different pools together?
I don't know what the gluster internals implications are, but as long
as I understand this correctly, then I think it would benefit the
management side of glusterfs.
It would certainly make peering more decentralized, as long as double
peering or running a simultaneous peer attach and peer probe don't
cause issues. This last point is very important :)
