(openSUSE 13.2 x86_64 KDE, Ubuntu 15.04)
Hello all,
Is anyone here an expert on ZFS? I've been experimenting with it, as I want to take advantage of its scalability and reliability.
So far, I've been pretty successful. I've managed to build a zpool on a mdadm RAID1 array (/dev/md0) over 2 3TB hdd's (/dev/sdc and /dev/sdd) . Nothing too difficult there.

sda3 is my system partition for openSUSE, and sda4 is my system partition for Ubuntu, on a dual-boot system. I do not want to use the zpool as a system partition, but only as a backup/storage device for both Ubuntu and openSUSE.

What I though I could do was reboot into Ubuntu, build the zpool there and mount it, and just use the zpool whenever I booted into either OS. However, after I created the zpool in Ubuntu, put some test data on it, and rebooted back into SUSE, not only was the test data gone, but the zpool was missing as well.

I tried a bit with the zfs import and export option, but I haven't been too successful with that yet, and it seems a bit brutish to do what I want to do. Is there a way to preserve a zpool across two systems over a reboot?
