I gave up on trying to remove the normal way. I pull the drive I wanted to remove from the machine, removed the drive in a 'missing' state from the pool (this takes 2-3 min to complete). Then hooked up the drive on USB and manually copied the
data back.
I cannot guarantee this will work 100% for all situations, but if your just doing 'basic' data storage it *should* be fine.
Also you get the added plus of your storage array actually being accessible during the file copy
