Force compression

"if the first portion of data being compressed is not smaller than the original, the compression of the file is disabled -- unless the filesystem is mounted with -o compress-force. In that case compression will always be attempted on the file only to be later discarded."

"The utility chattr supports setting file attribute c that marks the inode to compress newly written data. Setting the compression property on a file using btrfs property set <file> compression <zlib|lzo|zstd> will force compression to be used on that file using the specified algorithm."


  • chattr +c is the per-file equivalent of -o compress?
  • btrfs property set <file> compression is the per-file equivalent of -o compress-force?

chattr and btrfs property set don't affect each other? Jonathan (talk) 04:11, 15 January 2021 (UTC)
