i replaced my failing 4tb drives with 6tb drives. after recovering the array, it's still showing 4tb. how do i expand without losing my data?
LS420D
Version 1.85-0.01

I don't think the Buffalo firmware has a way to expand arrays in that way.
There is a guide to doing so manually but I think it relies on newer versions of mdadm using the latest metadata format:
https://raid.wiki.kernel.org/index.php/Growing#Extending_an_existing_RAID_array
The examples are all ext4 specific and would be different for the xfs filesystem even if it did work.
I think it would be much safer to create the new array and copy the data over to it.

so this model will support a 6tb drive i assume?
you're saying i should copy the data off the array to something external, delete the 4tb array, and see if i can build a new 6tb array?

That's correct, you'll have to delete the existing array and create a new one.

so back to back 36 hour waits to rebuild the array was a waste of time!
guess i know what i'm doing next time i have a disk failure or run out of space.
