Compressed_Reiser4

Contents

Purpose

Reiser4 compression improves disk access speed and also allows typically allows more data on the disk.

Limitations

Prepare the system

Emerge proper tools

emerge sys-fs/reiser4progs

Build your kernel with the proper reiser4 patch included

You may do this one of a few ways:

Once you get a patched kernel, you should find and enable the filesystem in menuconfig.

Create the filesystem

LZO compression (recommended)

LZO is faster but the compression is worse than gzip.

mkfs.reiser4 -o create=ccreg40,compress=lzo1 /dev/xxx

GZIP compression

mkfs.reiser4 -o create=ccreg40,compress=gzip1 /dev/xxx
