You don't actually need to install a new kernel - though it certainly won't
hurt.
Just reboot and you will be able to resize the array.

I'm always expecting md0 to show up first, followed by md1, md2, etc. but this is rarely actually the way that the arrays are ordered. It makes it kind of confusing when different utilities do things differently.
I think the correct word is "arbitrary", not "random".
Just adjust your expectations. Don't expect any particular order, and then
it won't look wrong.
Things tends to be listed in the order they are created, or the reverse of
that. Though in some cases it might be the ordering of some hash of some
value.
If you want something sorted, use "sort" :-)
