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 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, but am a bit of a newb when it comes to ZFS.

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.

I know this is already answered below, but just to explain what you saw: the problem is that “zpool import pool” means “import the pool named ‘pool’”. ZFS is telling you it found a pool named ‘ZStore’, but no pool named ‘pool’.

Thanks @Dan That helped. I was totally misunderstanding. Storage pool is back and showing up properly now.

If the disks are recognized from your OS the command:

zpoll import

should be enough to get the pool imported and visible in your current OS. You can check the status with command

zpool status

You can try to import it explicitly by name

zpoll import ZStore

P.S. Do not forget to set the pool online:

zpool online

You can check zpool-features features and if they are enabled or not in your case. Seems like zfs build in your case is new than the version which create it. The problem is if you update you will be able to mount only with same or upper version of zfs

What I can recommend you is to try (if available) with live version (but this with which you create the pool)

ok, tried upgrade and got: sudo zpool upgrade -a This system supports ZFS pool feature flags. All pools are already formatted using feature flags. Every feature flags pool already has all supported features enabled
