I'm seeing this also in the 2nd dmesg: [ 249.893310] BTRFS error (device sdg2): free space inode generation (0) did not match free space cache generation (26286) So you could try umounting the volume. And doing a one time mount with the clear_cache mount option. Give it some time to rebuild the space cache. After that you could umount again, and mount with enospc_debug and try to reproduce the enospc with another balance and see if dmesg contains more information this time.
