Restore ZFS Pool and storage data after a system re-install

I recently re-installed my host OS to Mint 19 64 bit, and am now trying to get all of my external drives back online. I had a ZFS storage pool made up of 4 x 1 TB disks, and set them to allow 1 drive to fail without losing data in my pool. Now, I want to get that Storage pool back up and running. My pool is simply called ZStore. How can I get the drives and pool back up and accessible in my Linux system? **EDIT**: I did the following:

# sudo zpool import
   pool: ZStore1
     id: 6113527918687515983
  state: ONLINE
 status: Some supported features are not enabled on the pool.
 action: The pool can be imported using its name or numeric identifier, though
	some features will not be available without an explicit 'zpool upgrade'.
 config:

	ZStore1                                          ONLINE
	  raidz1-0                                       ONLINE
	    usb-WDC_WD75_02ABYS-18A6B0_152D00539000-0:0  ONLINE
	    usb-WDC_WD75_02ABYS-18A6B0_152D00539000-0:1  ONLINE
	    usb-WDC_WD75_02ABYS-18A6B0_152D00539000-0:2  ONLINE
	    usb-WDC_WD75_02ABYS-18A6B0_152D00539000-0:3  ONLINE

But when I try zpool status or sudo zpool status I get

no pools available

Not sure what's going on. The pool shows online when I import, and all drives show online, but not getting anything with status check. tried

$ zpool online

then

$ zpool online ZStore1

then get missing device name, so I'm at a loss - again.
