I am not doing anything at all to the member disks, I am only manipulating the array (mb126) and providing the ouput of fsdisk -l / parted -l (with unnecessary info about other disks removed). > The one thing you mention that I can't write off as user error is "but > parted is not and seems to be forcibly applying what it believes to be > correct (ignoring the fact that it was only asked to display info, not > modify anything)".
