The capacity for the volume 'freenas-boot' is currently at 96%, while the recommended value is below

[Vince Claude]

I have 2 Free NAS servers running. Only difference in the two is size of the RAID drives.

One just (May 4) got "critical error" "The capacity for the volume 'freenas-boot' is currently at 96%, while the recommended value is below 80%.".

While one is running comfortable at 9% of USB boot fob, the other is at 96%. I have deleted a couple of old boot files and run boot scrub on the 96% fob but no change is the usage ... still 96%.

Would it be safe to say I have a FOB failure?

I recall there have been other threads on this topic where somehow users have managed to configure some service to cause files pile up at the FreeNAS bootdrive. I don't recall how or why. Try a search. You are definitely not alone.

Check the System - System Dataset tab - it's possible that Syslog and reporting database are on "freenas-boot" - change them there to be stored on your pool.

Is there a way to move these specifically without moving the entire system data set to the pool?

This is almost always the result of someone carelessly setting their FTP root folder to the boot device.

I'm imagining that there must be a way to script that outcome but it's outside my pay grade today ...

Boy, that would do it.

Unlikely. What's the output of ls -l / and du -sh /*?

 

[Vince Claude]

Thanks for the advice everyone.

Looks like there is 26 GB in /root (see below).
How do I clean it out?
How do I prevent it from happening again (could it be FTP root folder mentioned above).

Yep, there's your problem. Move it somewhere onto the pool. And if you're using FTP, check its configuration to make sure its root path isn't / or /root.

 

[Vince Claude]

Excuse my ignorance. I'm looking at /root and I don't see any 26 GB (below). Are they hidden?

What's in /root/media/?

 

[Vince Claude]

Found it ... in /root/media/Data1/Work (see below).

Remnants of a WGET from Jan 20 2016 ( I think WGET is an FTP function). I looked at FTP service and it's path points to /mnt/NAS2 which I believe is the RAID Zpool not the boot FOB.

Can I just delete all of the files form 2016 in /root/media/Data1/Work?

You could, but the simplest thing to do would be to delete /root/media in its entirety. You shouldn't ordinarily be storing anything significant in /root/.

Perfect! I removed /root/media and I am at 8% now instead of 96%.
Thanks so much for the help.
