			== OPTIONAL: Set Zpool to Expand ==
			We can set a Zpool to expand itself to fill all available storage by first taking the pool offline with '''zpool offline <zpool>.''' Now, we can bring it back online with a special flag that will tell it to expand to fill its storage space. Sometimes this is enabled by default, but if it appears not to be working, you can do this to rule this setting not being set out. We do this with '''zpool online -e <zpool>'''.

			If you cloned these drives directly from one drive to a larger drive, this won't work, as the partition table hasn't been reconfigured. You'll have to move the end partition and then expand the first one before running '''zpool''' '''online -e'''.
