0005 help
0006 Reiserfs is deprecated and scheduled to be removed from the kernel
0007 in 2025. If you are still using it, please migrate to another
0008 filesystem or tell us your usecase for reiserfs.
0009
0010 Reiserfs stores not just filenames but the files themselves in a
0011 balanced tree. Uses journalling.
0012
0013 Balanced trees are more efficient than traditional file system
0014 architectural foundations.
0015
0016 In general, ReiserFS is as fast as ext2, but is very efficient with
0017 large directories and small files. Additional patches are needed
0018 for NFS and quotas, please see
0019 <https://reiser4.wiki.kernel.org/index.php/Main_Page> for links.
0020
0021 It is more easily extended to have features currently found in
0022 database and keyword search systems than block allocation based file
0023 systems are. The next version will be so extended, and will support
0024 plugins consistent with our motto ``It takes more than a license to
0025 make source code open.''

0033 need, buy a support contract, or pay us to port it to another OS.

0038 help
0039 If you set this to Y, then ReiserFS will perform every check it can
0040 possibly imagine of its internal consistency throughout its
0041 operation. It will also go substantially slower. More than once we
0042 have forgotten that this was on, and then gone despondent over the
0043 latest benchmarks.:-) Use of this option allows our team to go all
0044 out in checking for consistency when debugging without fear of its
0045 effect on end users. If you are on the verge of sending in a bug
0046 report, say Y and you might get a useful error message. Almost
0047 everyone should say N.

0052 help
0053 Create under /proc/fs/reiserfs a hierarchy of files, displaying
0054 various ReiserFS statistics and internal data at the expense of
0055 making your kernel or module slightly larger (+8 KB). This also
0056 increases the amount of kernel memory required for each mount.
0057 Almost everyone but ReiserFS developers and people fine-tuning
0058 reiserfs or tracing problems should say N.

0064 Extended attributes are name:value pairs associated with inodes by
0065 the kernel or by users (see the attr(5) manual page for details).

0082 help
0083 Security labels support alternative access control models
0084 implemented by security modules like SELinux. This option
0085 enables an extended attribute handler for file security
0086 labels in the ReiserFS filesystem.
0087
0088 If you are not using a security module that requires using
0089 extended attributes for file security labels, say N.
