NTFS3
|
||||
=====
|
||||
|
||||
|
||||
Summary and Features
|
||||
====================
|
||||
|
||||
NTFS3 is fully functional NTFS Read-Write driver. The driver works with
|
||||
NTFS versions up to 3.1, normal/compressed/sparse files
|
||||
and journal replaying. File system type to use on mount is 'ntfs3'.
|
||||
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 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;
|
||||
- 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.
|
||||
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:
|
||||
|
||||
nls=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).
|
||||
Examples:
|
||||
'nls=utf8'
|
||||
* - 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).
|
||||
|
||||
uid=
|
||||
gid=
|
||||
umask= Controls the default permissions for files/directories created
|
||||
after the NTFS volume is mounted.
|
||||
Example: iocharset=utf8
|
||||
|
||||
fmask=
|
||||
dmask= Instead of specifying umask which applies both to
|
||||
files and directories, fmask applies only to files and
|
||||
dmask only to directories.
|
||||
* - uid=
|
||||
- :rspan:`1`
|
||||
* - gid=
|
||||
|
||||
nohidden Files with the Windows-specific HIDDEN (FILE_ATTRIBUTE_HIDDEN)
|
||||
attribute will not be shown under Linux.
|
||||
* - umask=
|
||||
- Controls the default permissions for files/directories created after
|
||||
the NTFS volume is mounted.
|
||||
|
||||
sys_immutable Files with the Windows-specific SYSTEM
|
||||
(FILE_ATTRIBUTE_SYSTEM) attribute will be marked as system
|
||||
immutable files.
|
||||
* - 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=
|
||||
|
||||
discard Enable support of the TRIM command for improved performance
|
||||
on delete operations, which is recommended for use with the
|
||||
solid-state drives (SSD).
|
||||
* - 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.
|
||||
|
||||
force Forces the driver to mount partitions even if 'dirty' flag
|
||||
(volume dirty) is set. Not recommended for use.
|
||||
- Permissions change for files/folders will be reported as successful,
|
||||
but they will remain 777.
|
||||
|
||||
sparse Create new files as "sparse".
|
||||
- Owner/group change will be reported as successful, butthey will stay
|
||||
as root.
|
||||
|
||||
showmeta Use this parameter to show all meta-files (System Files) on
|
||||
a mounted NTFS partition.
|
||||
By default, all meta-files are hidden.
|
||||
* - nohidden
|
||||
- Files with the Windows-specific HIDDEN (FILE_ATTRIBUTE_HIDDEN) attribute
|
||||
will not be shown under Linux.
|
||||
|
||||
prealloc Preallocate space for files excessively when file size is
|
||||
increasing on writes. Decreases fragmentation in case of
|
||||
parallel write operations to different files.
|
||||
* - sys_immutable
|
||||
- Files with the Windows-specific SYSTEM (FILE_ATTRIBUTE_SYSTEM) attribute
|
||||
will be marked as system immutable files.
|
||||
|
||||
no_acs_rules "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, but
|
||||
they will stay as root
|
||||
* - discard
|
||||
- Enable support of the TRIM command for improved performance on delete
|
||||
operations, which is recommended for use with the solid-state drives
|
||||
(SSD).
|
||||
|
||||
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.
|
||||
* - force
|
||||
- Forces the driver to mount partitions even if volume is marked dirty.
|
||||
Not recommended for use.
|
||||
|
||||
noatime All files and directories will not update their last access
|
||||
time attribute if a partition is mounted with this parameter.
|
||||
This option can speed up file system operation.
|
||||
* - 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.
|
||||
|
||||
ToDo list
|
||||
* - 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 (currently journal replaying is supported) over JBD.
|
||||
|
||||
- Full journaling support over JBD. Currently journal replaying is supported
