Hi, According to man btrfs [1], I assume that metadata_ratio=1 mount option should force allocation of one metadata chunk after every allocated data chunk. However, when I set this option and start filling btrfs with "dd if=/dev/zero of=dummyfile.dat", only data chunks are allocated but no metadata ones. So, how does the metadata_ratio option really work? Note that I'm trying to use this option as a workaround of the bug reported here: https://www.spinics.net/lists/linux-btrfs/msg75104.html i.e. I want to manually preallocate metadata chunks to avoid nightly ENOSPC errors. Best regards.
