I had just sent two patches to fix false enospc error for compression, please have a try, they fix false enospc error in my test environment. btrfs: fix false enospc for compression btrfs: improve inode's outstanding_extents computation I apply these two patchs in linux upstream tree, the latest commit is 41844e36206be90cd4d962ea49b0abc3612a99d0.
