Optimal pool performance requires used space remain below 80%.

[kappclark]

I see the error/alert
"Space usage for pool "freenas-boot" is 82%. Optimal pool performance requires used space remain below 80%."

after applying the latest update ... I have searched for a way to remedy this -- is this something I need to worry about ?? (The pool is 2 16G flash drives -- are there filse I need to remove to free up space ?

maybe there are log files growing quite large?

 

[kappclark]

Oh - yes that is a good idea - just do not want to delete essential files

Delete your old un used boot environments to clear up space.

 

[kappclark]

so it is strange, but after dropping to a command prompt, I am not sure how to cd to the flash drive da0

 

[Jailer]

Do it from the gui.

As Jailer noted delete old boot environments, not current and likely not one previous version for roll back if needed.

PS.. Guessing this is about your boot pool because of details in the post, but it is generally a good idea to give a little more explanation and some details about your system. Here is a guide for that:

Thank you Chris for the link to the guide on boot environments and forum guidelines.. I will review - still have the freenas training wheels on ..

I have been away for Thanksgiving and this error showed on my return .. my freenas-boot pool is a mirrored pair of 16G flash drives. I have removed one of the flash drives, rebooted the box, and reattached the flash drive..now both devices show up under Boot Pool status - it is now re-silvering ...
