Hubert Tonneu posted a tool that allows you to add and remove disks from a
raid set... It also allows you to change chunk size at the same time. So
you can change your chunk size by specifying a new raidset with the exact
same drives, but with a new chunksize.
He said is was very alpha, so you definitely want to have a fresh backup...
But it can save you the time of restoring from it if all goes well.
He posted it to the list 9/18 in a post titled "RE: question about adding a
disk: Now possible". It's written in yet-another-scripting-language Pliant,
so you'll need to get that as well.
I used it, and it worked fine for me. Let us know if you use it too
