Compiling the Kernel with ReiserFS Support
Support for ReiserFS has been included in the stable Linux
kernel since 2.4.1. Enable support for ReiserFS
(CONFIG_REISERFS_FS) in the Filesystems section of
the kernel configuration.
Filesystems ---> <*> Reiserfs support [ ] Have reiserfs do extra internal checking [ ] Stats in /proc/fs/reiserfs
Depending on which sublevel release you are using, you might
also need to activate support for development drivers
(CONFIG_EXPERIMENTAL) because ReiserFS was not
considered stable until 2.4.18. ReiserFS may also be compiled as a
loadable kernel module.
After you enable support for ReiserFS, two more options appear.
The first, CONFIG_REISERFS_CHECK, turns on
debugging for ReiserFS. This option should always be disabled, unless
you are experiencing problems and are planning to send in a bug
report. In that case, turning on the extra internal checking might
provide you with a useful error message that you can show to
developers. Filesystem performance will be seriously hindered when
this option is enabled, so don’t forget to disable it after you have
collected the error messages you need.
Enabling statistic reporting for
/proc/fs/reiserfs
(CONFIG_REISERFS_PROC_INFO) will add some
additional memory overhead to your kernel, but will provide you with
statistics and internal data about your filesystem. The
/proc/fs/reiserfs/ directory contains a
subdirectory for each mounted ReiserFS partition and a file named
version that contains the current filesystem ...
