Hi list,
This is something I've discussed on IRC and we achieved a conclusion
that this might be useful, but somewhat limited use-case count might not
warrant the effort to be implemented.
What I have in mind is allowing a member of an array to be paired with a
spare while the array is on-line. The spare disk would then be filled
with exactly the same data and would, in the end, replace the active
member. The replaced disk could then be hot-removed without the array
ever going into degraded mode.
I wanted to start a discussion whether this at all makes sense, what can
be the use cases etc.

Cheers
