Hi,

I found some logs on the daily security output:

For what I see can be ZFS related.

If anyone have any hints, please tell :)

I kinda got curious about this:

+ZFS storage pool version: features support (5000)

How can I figure out if my pools are from different versions and may this
be the culprit here?

thanks,
