Re: Growing a raid array online with different capacity disks

Yes the systems cited by the OP have nothing to do with RAID5, and in
fact are proprietary - definitely as in "non-standard", and I think
also none are open source.

They do seem to have a lot of flexibility - mix and match any number
and size of drives, toss another random-sized drive in an expand your
capacity. Apparently particularly well-suited to hobby/soho/sme users;
I've especially heard good things about Drobo for that market.

Think of the usual reaction a corporate IT guy (used to what he calls
"normal RAID", ie not mdadm) first hears about setting up mdadm RAID10
on odd numbers of drives, even say 3 - like "huh??!!"

Oh I'm not proposing it, I'm asking if mdadm can do it, like the other
products can.

No 'product' can 'do' a 1+1+1+3 TB RAID5, or it will not be a RAID5 but
something else.
