Zfs pool online but cannot access mount

[d4nnyb]

Hello,

I have an issue with my ZFS pool, it all started when I realised that my pool was degraded. One of my 8TB drives was not online and the pool was working off the other drive as the are in a mirror.
I have both Hdds in a caddy and it just needed turning back on.
When it came back online it resilvered and I assumed that it would all just work again.. Nope.

The zfs status is showing both drives are online and the mount is also mounted.

When I navigate to the mount my session just hangs, when rebooting the node it hangs. The dataset is also shared by nfs and I have halted the nfs service as I figured that wasn't helping.

Any info you require to help please ask. I'm aware this is not normal format but I have never posted here before.

Thank you

pool: deadpool
 state: ONLINE
status: Some supported and requested 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(7) for details.
