XFS is a high performance journaling filesystem which originated
|
|
on the SGI IRIX platform. It is completely multi-threaded, can
|
|
support large files and large filesystems, extended attributes,
|
|
variable block sizes, is extent based, and makes extensive use of
|
|
Btrees (directories, extents, free space) to aid both performance
|
|
and scalability.
|
|
|
|
Refer to the documentation at <http://oss.sgi.com/projects/xfs/>
|
|
for complete details. This implementation is on-disk compatible
|
|
with the IRIX version of XFS.
|
|
|
|
To compile this file system support as a module, choose M here: the
|
|
module will be called xfs. Be aware, however, that if the file
|
|
system of your root partition is compiled as a module, you'll need
|
|
to use an initial ramdisk (initrd) to boot.

depends on XFS_FS
|
|
help
|
|
If you say Y here, you will be able to set limits for disk usage on
|
|
a per user and/or a per group basis under XFS. XFS considers quota
|
|
information as filesystem metadata and uses journaling to provide a
|
|
higher level guarantee of consistency. The on-disk data format for
|
|
quota is also compatible with the IRIX version of XFS, allowing a
|
|
filesystem to be migrated between Linux and IRIX without any need
|
|
for conversion.
|
|
|
|
If unsure, say N. More comprehensive documentation can be found in
|
|
README.quota in the xfsprogs package. XFS quota can be used either
|
|
with or without the generic quota support enabled (CONFIG_QUOTA) -
|
|
they are completely independent subsystems.

help
|
|
Security labels support alternative access control models
|
|
implemented by security modules like SELinux. This option
|
|
enables an extended attribute namespace for inode security
|
|
labels in the XFS filesystem.
|
|
|
|
If you are not using a security module that requires using
|
|
extended attributes for inode security labels, say N.

POSIX Access Control Lists (ACLs) support permissions for users and
|
|
groups beyond the owner/group/world scheme.
|
|
|
|
To learn more about Access Control Lists, visit the POSIX ACLs for
|
|
Linux website <http://acl.bestbits.at/>.
|
|
|
|
If you don't know what Access Control Lists are, say N.

|
|
help
|
|
If you say Y here you will be able to mount and use XFS filesystems
|
|
which contain a realtime subvolume. The realtime subvolume is a
|
|
separate area of disk space where only file data is stored. The
|
|
realtime subvolume is designed to provide very deterministic
|
|
data rates suitable for media streaming applications.
|
|
|
|
See the xfs man page in section 5 for a bit more information.

|
|
This feature is unsupported at this time, is not yet fully
|
|
functional, and may cause serious problems.
|
|
|

If unsure, say N.
