Reiserfs is deprecated and scheduled to be removed from the kernel
|
||
|
|
in 2025. If you are still using it, please migrate to another
|
||
|
|
filesystem or tell us your usecase for reiserfs.
|
||
|
|
|
||
|
|
Reiserfs stores not just filenames but the files themselves in a
|
||
|
|
balanced tree. Uses journalling.
|
||
|
|
|
||
|
|
Balanced trees are more efficient than traditional file system
|
||
|
|
architectural foundations.
|
||
|
|
|
||
|
|
In general, ReiserFS is as fast as ext2, but is very efficient with
|
||
|
|
large directories and small files. Additional patches are needed
|
||
|
|
for NFS and quotas, please see
|
||
|
|
<https://reiser4.wiki.kernel.org/index.php/Main_Page> for links.
|
||
|
|
|
||
|
|
It is more easily extended to have features currently found in
|
||
|
|
database and keyword search systems than block allocation based file
|
||
|
|
systems are. The next version will be so extended, and will support
|
||
|
|
plugins consistent with our motto ``It takes more than a license to
|
||
|
|
make source code open.''
|
||
|
|
|
||
|
|

|

to learn more about reiserfs.

need, buy a support contract, or pay us to port it to another OS.

If you set this to Y, then ReiserFS will perform every check it can
|
||
|
|
possibly imagine of its internal consistency throughout its
|
||
|
|
operation. It will also go substantially slower. More than once we
|
||
|
|
have forgotten that this was on, and then gone despondent over the
|
||
|
|
latest benchmarks.:-) Use of this option allows our team to go all
|
||
|
|
out in checking for consistency when debugging without fear of its
|
||
|
|
effect on end users. If you are on the verge of sending in a bug
|
||
|
|
report, say Y and you might get a useful error message. Almost
|
||
|
|
everyone should say N.

Create under /proc/fs/reiserfs a hierarchy of files, displaying
|

|
|
various ReiserFS statistics and internal data at the expense of
|
||
|
|
making your kernel or module slightly larger (+8 KB). This also
|
||
|
|
increases the amount of kernel memory required for each mount.
|
||
|

Almost everyone but ReiserFS developers and people fine-tuning
|

reiserfs or tracing problems should say N.

Extended attributes are name:value pairs associated with inodes by

the kernel or by users (see the attr(5) manual page for details).

Security labels support alternative access control models
|

implemented by security modules like SELinux. This option
|

|

enables an extended attribute handler for file security
|
||
|

labels in the ReiserFS filesystem.

If you are not using a security module that requires using

|

extended attributes for file security labels, say N.
