Art,
There is no dynamic way to rebuild raid group sizing, or allocate from one raid group to another. Your statement about the safest way is also the only way that I have ever heard of (well, I guess volcopy would work, copying to another volume, destroying and rebuilding the source, and volcopy back).

I have a current volume (vol0) that has a raidgroup size of 8. I had 3 spares that weren't being used and I wanted to add them to the volume, but like an idiot didn't check the raidgroup size. Thus when I added the 3 disks to the volume (vol0) 1 went to raidgroup 0 and the other 2 went to raidgroup 1 as a parity drive and a data drive.
This will create a performance problem from what I can tell not mention another parity drive being used.
I'd like to get these two disks back under raid group 0 if I can.
Suggestions on the best way to do this would be appreciated.
I'm thinking the safest way is to back it up and recreate the volumes and restore.
Thanks
