ZFS Pool gone after reboot

[omitted]

Ran into a new issue after most recent apt-get upgrade. Looking for some help.

Current Setup
1) 2 node cluster
2) current issue on node 2
3) storage on each node
rpool for boot
tank for vm storage
4) Versions
node 1
Kernel Version
Linux 4.4.49-1-pve #1 SMP PVE 4.4.49-86
PVE Manager Version
pve-manager/4.4-13/7ea56165

node 2
Kernel Version
Linux 4.4.59-1-pve #1 SMP PVE 4.4.59-87
PVE Manager Version
pve-manager/4.4-13/7ea56165

5) Using the pve-no-subscription repository

The Issue
- Recently ran apt-get upgrade and apt-get dist-upgrade on both nodes
- rebooted node 2
- node 2 rpool "tank" was no longer available
- zpool status only shows rpool
- zpool import -a shows no pools available to import

Attempts:
- I have gone through several pages of fixes but haven't come across anything that has worked
- Tried this article from top down: https://github.com/zfsonlinux/zfs/issues/2927 without success
- Also read through https://groups.google.com/a/zfsonlinux.org/forum/#!topic/zfs-discuss/A4IkSIMQ4JI and
https://groups.google.com/a/zfsonlinux.org/forum/#!msg/zfs-discuss/xKJPcvTDieU/enceL5YEfQMJ

I can reproduce the issue still:
1) zpool create -f tank /dev/nvme0n1 /dev/nvme1n1
2) zpool status
pool: rpool
state: ONLINE
pool: tank
state: ONLINE
3) reboot
4) zpool status only shows rpool

Any direction would be greatly appreciated

Thanks!

what does "lsblk" and "blkid /dev/nvme0n1" output?

What about zpool import? Is it shown there?

I upgraded to the 5 beta and the issue resolved.
