Have already deleted the docker img and keep getting the error.

    Seems like this was the problem

     

     

    Had to delete some files, and ran the commands @johnnie.black mentioned.

     

    Haven't seen an error yet.

     

    Any way to prevent this from happening.  This has been the second time I've had to do a balance.

    Run this balance once a week, you can use the user scripts plugin:

      

    btrfs balance start -dusage=75 /mnt/cache

     

    Once unRAID gets to kernel 4.14 this issue should get fixed or at least improve.
