11 NTFS3 is fully functional NTFS Read-Write driver. The driver works with
12 NTFS versions up to 3.1, normal/compressed/sparse files
13 and journal replaying. File system type to use on mount is 'ntfs3'.
15 - This driver implements NTFS read/write support for normal, sparse and
17 - Supports native journal replaying;
18 - Supports extended attributes
19 Predefined extended attributes:
20 - 'system.ntfs_security' gets/sets security
21 descriptor (SECURITY_DESCRIPTOR_RELATIVE)
22 - 'system.ntfs_attrib' gets/sets ntfs file/dir attributes.
23 Note: applied to empty files, this allows to switch type between
24 sparse(0x200), compressed(0x800) and normal;
25 - Supports NFS export of mounted NTFS volumes.
30 The list below describes mount options supported by NTFS3 driver in addition to
33 ===============================================================================
35 nls=name This option informs the driver how to interpret path
36 strings and translate them to Unicode and back. If
37 this option is not set, the default codepage will be
38 used (CONFIG_NLS_DEFAULT).
44 umask= Controls the default permissions for files/directories created
45 after the NTFS volume is mounted.
48 dmask= Instead of specifying umask which applies both to
49 files and directories, fmask applies only to files and
50 dmask only to directories.
52 nohidden Files with the Windows-specific HIDDEN (FILE_ATTRIBUTE_HIDDEN)
53 attribute will not be shown under Linux.
55 sys_immutable Files with the Windows-specific SYSTEM
56 (FILE_ATTRIBUTE_SYSTEM) attribute will be marked as system
59 discard Enable support of the TRIM command for improved performance
60 on delete operations, which is recommended for use with the
61 solid-state drives (SSD).
63 force Forces the driver to mount partitions even if 'dirty' flag
64 (volume dirty) is set. Not recommended for use.
66 sparse Create new files as "sparse".
68 showmeta Use this parameter to show all meta-files (System Files) on
69 a mounted NTFS partition.
70 By default, all meta-files are hidden.
72 prealloc Preallocate space for files excessively when file size is
73 increasing on writes. Decreases fragmentation in case of
74 parallel write operations to different files.
76 no_acs_rules "No access rules" mount option sets access rights for
77 files/folders to 777 and owner/group to root. This mount
78 option absorbs all other permissions:
79 - permissions change for files/folders will be reported
80 as successful, but they will remain 777;
81 - owner/group change will be reported as successful, but
82 they will stay as root
84 acl Support POSIX ACLs (Access Control Lists). Effective if
85 supported by Kernel. Not to be confused with NTFS ACLs.
86 The option specified as acl enables support for POSIX ACLs.
88 noatime All files and directories will not update their last access
89 time attribute if a partition is mounted with this parameter.
90 This option can speed up file system operation.
92 ===============================================================================
97 - Full journaling support (currently journal replaying is supported) over JBD.
