ZFS error on pool

Hello,
I have some errors on one of our zfs pools. I cannot perform any action that is related to ZFS operations like pool scrub, snapshots, ...

Maybe anyone is able to help ?

The node is one of our old nodes with consumer hardware (Asus H170M-PLUS, Core i7 and no ecc ram). ZFS is running on Samsung SSD EVO.
Zpool status looks good so far. Maybe it is somehow related to the hardware. But please have a look.

proxmox-ve: 6.2-1 (running kernel: 5.4.60-1-pve)
zfsutils-linux: 0.8.4-pve1

zpool status
pool: zpool1
state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
the pool may no longer be accessible by software that does not support
the features. See zpool-features(5) for details.

Youre right, this output is from a zfs enabled rescue system.
I have bootet up again the server and did an import of the pool (this time with pve kernel). Here is the outcome:

I keep seeing these output to my proxmox console too:

Code: 
78436.716999] zd0: p1
[78436.719978] zd16: p1 p2 p3
[78436.724023] zd32: p1 p2
[78436.732161] zd48: p1 p2 p3 p4 < p5 p6 >
[78436.738724] zd64: p1 p3

Do I need to be concerned? Can't find anything else on Google about this apart from this post!
 
Hey,

I have some errors on one of our zfs pools. I cannot perform any action that is related to ZFS operations like pool scrub, snapshots,
Click to expand...

2 or 3 pve-kernel ago, root has loosed his direct access on zpool / zfs commands. Have you tried with an account with user right granted by sudo ?
If not, try to see if you access zpool/zfs commands

Best regards,
