Boot Drive Capacity Warning

[Kortex]

The system is throwing a warning for the boot drive being 82% full. Interestingly:

Why would 11.1-U7 be taking up 12 gigs? Thank you!!

The system is throwing a warning for the boot drive being 82% full. Interestingly:

I wonder if you don't have some other snapshots in your boot pool that are taking up this space.
Would you share the output of zfs list -t snapshot?
Here is the similar listing from my system:

As you can see, the 11.1-U7 part is only 8.51GB.

It is also possible (I have seen it before) that you might have put some data in your /root or someplace else that is being stored on the boot pool instead of in the data pool.

It looks like data was written between 07-05-2017 and 07-24-2017 and then included in the snapshot. What do I do about that?

 

[Kortex]

Does anyone know what to do here? The setup doesn't make sense and I'm lost.

 

[Ericloewe]

What's the output of zfs list -r -o space freenas-boot?

 

[Kortex]

I still don't understand what the issue is.

Do you still get the same message? Now you have roughly 2GB free more than before...

[Kortex]

I'm not getting the messages now, no. Are the others safe to delete though? 11.0-U4, 11.1-RELEASE, 11.1-U2... I just don't delete 11.1-U7 I guess?
