I think I asked this once before, if so I apologize for the redundancy - 
but then again maybe something's changed...

I've got a RAID-10 array with four drives.  It's nearing capacity, and I 
need to explore expansion options.  Can I simply add a pair of new 
drives?  Or do I have to archive the information first and rebuild the 
array from scratch?

It is not currently possible to resize a raid-10.

In my mind, it should not be that difficult, tho, to do it.

Is resize an operation that needs to be done with the fs unmounted?
