Growing a graid3?

[Eike Bernhardt]

Hello,

is it possible to expand a existing graid3?

I have a graid3 consisting of 3x 250GB drives, which is nearly full.

My idea would be to swap out each disk one after one with a bigger disk,
let the graid3 rebuild itself between swaps, and then use growfs to
resize the filesystem to the new availiabale maximum size.

Is this possible? Has anyone tried this?

Thanks,
  Eike
