[gentoo-user] resize raid1 array

[Rasmus Andersen]

Hello,

I had a raid1/mirror array of two 200G disks. Then one failed and I
thought 'lets get two 500G disks and just ease them in, they are cheap'.
So I added the full 500G partition from the first disk to the degraded
array, watched the resync, removed the remaining 200G disk and added the
last 500G disk.

My hope now was that I would be able to tell the kernel that md0 now is
500G, not 200G. But alas, I have not been able to do so. Is there a way
to do this? Or is the only way forward to shrink the partitions and
create new 300G ones alongside?

Thanks,
  Rasmus
