Unable to Mount Full Zpool

That would work if you intend to permanently expand the pool.

I strongly discourage you from trying this; your problem is not understood, and those extra drives may be your life boats. Add one small drive, and if you get access to your data, abandon ship. If adding one extra drive does not fix your problem, then at least you've only wasted one drive and you can always upgrade it to a mirror if required.

To be more clear, while it seems likely that you can't mount because of a lack of free space, I don't think anybody is 100% certain of it.

Just incase anyone was curious. Expanding the pool allowed it to mount. I was able to recover the data after that.

Excellent!

And great to know the cause and solution.
