Hi,

I have tried to find an answer, but my "search fu powers" are now
coming to a end.
What i want to do was more or less detailed by Neil in
http://marc.info/?l=linux-raid&m=129785210102555
the section titled "When reshaping an array to fewer devices, allow
'size' to be increased"

but just to explain:
I have a 9 devices in a RAID5
6 of these are now 2TB disks (I really love hot replace!)
while the other 3 are still 1TB disks

I would now like to grow the array to 6x2TB instead of the present 9x1TB.

Is this possible and I just can't find how, or have there just been to
many other great features instead?
(I have started a ext4 offline shrink.. but it is a real pain.)

Sorry, but this function hasn't been implemented yet.
