It looks like you tried to execute a program named /srv/dcache/pools/2/foo, and there is no such program. That doesn't say anything about the filesystem. > balancing also fails, e.g.: > # btrfs balance start -dusage=50 /srv/dcache/pools/2 > ERROR: error during balancing '/srv/dcache/pools/2': No space left on device Balance is basically like a defrag. You have less than 0.01% space free, which is not enough to do a defrag. Either free up some space, or don't bother trying to defrag.
