Current ntfs3 rst documentation is broken. I turn table to list table as this is current Linux documentation quide line. Simple table also did not quite work in our situation as we need to span rows together. It still look quite good as text so we did not loss anything. This will also make diffing quite bit more pleasure. Signed-off-by: Kari Argillander <kari.argillander@gmail.com> Signed-off-by: Konstantin Komarov <almaz.alexandrovich@paragon-software.com>

Summary and Features
|
|
====================
|
|
|
|
NTFS3 is fully functional NTFS Read-Write driver. The driver works with NTFS
|
|
versions up to 3.1. File system type to use on mount is *ntfs3*.
|
|
|
|
- This driver implements NTFS read/write support for normal, sparse and
|
|
compressed files.
|
|
- Supports native journal replaying.
|
|
- Supports NFS export of mounted NTFS volumes.
|
|
- Supports extended attributes. Predefined extended attributes:
|
|
|
|
- *system.ntfs_security* gets/sets security
|
|
|
|
Descriptor: SECURITY_DESCRIPTOR_RELATIVE
|
|
|
|
- *system.ntfs_attrib* gets/sets ntfs file/dir attributes.
|
|
|
|
Note: Applied to empty files, this allows to switch type between
|
|
sparse(0x200), compressed(0x800) and normal.
|
|
|
|
Mount Options
|
|
=============
|
|
|
|
The list below describes mount options supported by NTFS3 driver in addition to
|
|
generic ones. You can use every mount option with **no** option. If it is in
|
|
this table marked with no it means default is without **no**.
|
|
|
|
.. flat-table::
|
|
:widths: 1 5
|
|
:fill-cells:
|
|
|
|
* - iocharset=name
|
|
- This option informs the driver how to interpret path strings and
|
|
translate them to Unicode and back. If this option is not set, the
|
|
default codepage will be used (CONFIG_NLS_DEFAULT).
|
|
|
|
Example: iocharset=utf8
|
|
|
|
* - uid=
|
|
- :rspan:`1`
|
|
* - gid=
|
|
|
|
* - umask=
|
|
- Controls the default permissions for files/directories created after
|
|
the NTFS volume is mounted.
|
|
|
|
* - dmask=
|
|
- :rspan:`1` Instead of specifying umask which applies both to files and
|
|
directories, fmask applies only to files and dmask only to directories.
|
|
* - fmask=
|
|
|
|
* - noacsrules
|
|
- "No access rules" mount option sets access rights for files/folders to
|
|
777 and owner/group to root. This mount option absorbs all other
|
|
permissions.
|
|
|
|
- Permissions change for files/folders will be reported as successful,
|
|
but they will remain 777.
|
|
|
|
- Owner/group change will be reported as successful, butthey will stay
|
|
as root.
|
|
|
|
* - nohidden
|
|
- Files with the Windows-specific HIDDEN (FILE_ATTRIBUTE_HIDDEN) attribute
|
|
will not be shown under Linux.
|
|
|
|
* - sys_immutable
|
|
- Files with the Windows-specific SYSTEM (FILE_ATTRIBUTE_SYSTEM) attribute
|
|
will be marked as system immutable files.
|
|
|
|
* - discard
|
|
- Enable support of the TRIM command for improved performance on delete
|
|
operations, which is recommended for use with the solid-state drives
|
|
(SSD).
|
|
|
|
* - force
|
|
- Forces the driver to mount partitions even if volume is marked dirty.
|
|
Not recommended for use.
|
|
|
|
* - sparse
|
|
- Create new files as sparse.
|
|
|
|
* - showmeta
|
|
- Use this parameter to show all meta-files (System Files) on a mounted
|
|
NTFS partition. By default, all meta-files are hidden.
|
|
|
|
* - prealloc
|
|
- Preallocate space for files excessively when file size is increasing on
|
|
writes. Decreases fragmentation in case of parallel write operations to
|
|
different files.
|
|
|
|
* - acl
|
|
- Support POSIX ACLs (Access Control Lists). Effective if supported by
|
|
Kernel. Not to be confused with NTFS ACLs. The option specified as acl
|
|
enables support for POSIX ACLs.
|
|
|
|
Todo list
|
|
=========
|
|
- Full journaling support over JBD. Currently journal replaying is supported
|
|
which is not necessarily as effectice as JBD would be.
