CX4 pool stuck?

We have run out of spare disks, and due to continued disk failures, I need to delete a pool and make it smaller.

Unfortunately, a drive failed during the drop operation, and it now appears stuck. It's been several hours with no progress.

I have 90 drives in the pool, and I need to get the pool deleted ASAP in order to create several smaller Raid Groups, which have better flexability than a single large pool.
