ReadyNAS OS 6.10.0 Hotfix 2

Hey guys, within a few days after upgrading my Pro6 with 6.10.0 Hotfix 2, appears to be reporting reporting that I am out of space for the first time. Am I really out of space from the below photos? Is there a more recent version of 6.10.0 or is Hotfix 2 the latest available?  And if this is a defect, Is this on the "fix list"?

Somehow you ended up with a bunch of partially filled BTRFS chunks.  So the free space was there (as reported by df), but wasn't actually available to the file system.   Running balance and scrub consolidated the chunks (you can think of it as defragging free space), so it resolved the problem.

 

If you look at btrfs space, you should also run btrfs filesystem df in addition to the normal df.

This seemed to resolve itself after I did a Balance and Scrub.  It's now back at 5.98TB free.  But I am not sure what caused it... 

 

Thanks!
