Hello All,

I am in the research phase of building a Gentoo-based backup/NAS target
using md software RAID or (maybe) btrfs or zfs.  One thing that I am not
finding much info about is any facility for automatically rebuilding an
array when a new, matching drive is inserted.  At this stage, the plan is to
use four identical drives in a RAID10-style setup.

Is any here aware of the right way to configure this?

Thanks,

-Andy
