I have a ZFS scrub configured to run twice a month. Last nights run generated four separate email messages which I've copied below in the order they were sent. I'm not at all sure what the messages mean?? Or how serious they are. I also have regular short and long SMART self tests scheduled. Here are my questions:
1 - I've done some poking around in the forums but I'd like to know what the messages below mean and what action I should take?
2 - I do not have Periodic Snapshot task scheduled for this Vol. Should I do this?
3 - Obviously I'm out of my area of expertise. I would like to know if anyone knows of a resource/guide for maintaining the health of the NAS Vol and how to respond to various issues that can occur.
Thanks!
