ZFS Pools not mounted 16.04

The pool (two 4tb drives) were happily running in 14.10 but after upgrading to 16.04 they stopped. Entering:

/sbin/modprobe zfs
zpool import Raid
zpool status

Everything at this point is mounted and accessible. /etc/init/zpool-import.conf and rc.local look fine.

Any help is appreciated.

OK - that was easy... but I don't know why (maybe because I skipped over 15.10?):

sudo apt-get install zfsutils-linux

showed a broken package and two zfs.doc packages pending with different versions. I suspected zfsutils-linux wasn't really installed and

sudo apt-get remove zfsutils-linux

confirmed it wasn't installed. So failing to have any other ideas:

sudo apt-get remove zfs.doc
sudo apt-get install zfsutils-linux

Removing zfs.doc removed all if it's dependencies, and the re-install was successful.

After a reboot everything mounted fine.

Experienced same problem after upgrade to Ubuntu 16.04.

The package zfs.doc appeared to be installed, but a:

sudo apt-get remove zfs.doc

sudo apt-get install zfsutils-linux

Fixed the issue. Thanks for shareing.
