Even better is to simply use the Device-Mapper for linear raid and then you do

not have this problem with odd numbers of sectors.

ChangeLog
|
||||
=========
|
||||
|
||||
2.1.30:
|
||||
- Fix writev() (it kept writing the first segment over and over again
|
||||
instead of moving onto subsequent segments).
|
||||
- Fix crash in ntfs_mft_record_alloc() when mapping the new extent mft
|
||||
record failed.
|
||||
2.1.29:
|
||||
- Fix a deadlock when mounting read-write.
|
||||
2.1.28:
|
||||
- Fix a deadlock.
|
||||
2.1.27:
|
||||
- Implement page migration support so the kernel can move memory used
|
||||
by NTFS files and directories around for management purposes.
|
||||
- Add support for writing to sparse files created with Windows XP SP2.
|
||||
- Many minor improvements and bug fixes.
|
||||
2.1.26:
|
||||
- Implement support for sector sizes above 512 bytes (up to the maximum
|
||||
supported by NTFS which is 4096 bytes).
|
||||
- Enhance support for NTFS volumes which were supported by Windows but
|
||||
not by Linux due to invalid attribute list attribute flags.
|
||||
- A few minor updates and bug fixes.
|
||||
2.1.25:
|
||||
- Write support is now extended with write(2) being able to both
|
||||
overwrite existing file data and to extend files. Also, if a write
|
||||
to a sparse region occurs, write(2) will fill in the hole. Note,
|
||||
mmap(2) based writes still do not support writing into holes or
|
||||
writing beyond the initialized size.
|
||||
- Write support has a new feature and that is that truncate(2) and
|
||||
open(2) with O_TRUNC are now implemented thus files can be both made
|
||||
smaller and larger.
|
||||
- Note: Both write(2) and truncate(2)/open(2) with O_TRUNC still have
|
||||
limitations in that they
|
||||
- only provide limited support for highly fragmented files.
|
||||
- only work on regular, i.e. uncompressed and unencrypted files.
|
||||
- never create sparse files although this will change once directory
|
||||
operations are implemented.
|
||||
- Lots of bug fixes and enhancements across the board.
|
||||
2.1.24:
|
||||
- Support journals ($LogFile) which have been modified by chkdsk. This
|
||||
means users can boot into Windows after we marked the volume dirty.
|
||||
The Windows boot will run chkdsk and then reboot. The user can then
|
||||
immediately boot into Linux rather than having to do a full Windows
|
||||
boot first before rebooting into Linux and we will recognize such a
|
||||
journal and empty it as it is clean by definition.
|
||||
- Support journals ($LogFile) with only one restart page as well as
|
||||
journals with two different restart pages. We sanity check both and
|
||||
either use the only sane one or the more recent one of the two in the
|
||||
case that both are valid.
|
||||
- Lots of bug fixes and enhancements across the board.
|
||||
2.1.23:
|
||||
- Stamp the user space journal, aka transaction log, aka $UsnJrnl, if
|
||||
it is present and active thus telling Windows and applications using
|
||||
the transaction log that changes can have happened on the volume
|
||||
which are not recorded in $UsnJrnl.
|
||||
- Detect the case when Windows has been hibernated (suspended to disk)
|
||||
and if this is the case do not allow (re)mounting read-write to
|
||||
prevent data corruption when you boot back into the suspended
|
||||
Windows session.
|
||||
- Implement extension of resident files using the normal file write
|
||||
code paths, i.e. most very small files can be extended to be a little
|
||||
bit bigger but not by much.
|
||||
- Add new mount option "disable_sparse". (See list of mount options
|
||||
above for details.)
|
||||
- Improve handling of ntfs volumes with errors and strange boot sectors
|
||||
in particular.
|
||||
- Fix various bugs including a nasty deadlock that appeared in recent
|
||||
kernels (around 2.6.11-2.6.12 timeframe).
|
||||
2.1.22:
|
||||
- Improve handling of ntfs volumes with errors.
|
||||
- Fix various bugs and race conditions.
|
||||
2.1.21:
|
||||
- Fix several race conditions and various other bugs.
|
||||
- Many internal cleanups, code reorganization, optimizations, and mft
|
||||
and index record writing code rewritten to fit in with the changes.
|
||||
- Update Documentation/filesystems/ntfs.txt with instructions on how to
|
||||
use the Device-Mapper driver with NTFS ftdisk/LDM raid.
|
||||
2.1.20:
|
||||
- Fix two stupid bugs introduced in 2.1.18 release.
|
||||
2.1.19:
|
||||
- Minor bugfix in handling of the default upcase table.
|
||||
- Many internal cleanups and improvements. Many thanks to Linus
|
||||
Torvalds and Al Viro for the help and advice with the sparse
|
||||
annotations and cleanups.
|
||||
2.1.18:
|
||||
- Fix scheduling latencies at mount time. (Ingo Molnar)
|
||||
- Fix endianness bug in a little traversed portion of the attribute
|
||||
lookup code.
|
||||
2.1.17:
|
||||
- Fix bugs in mount time error code paths.
|
||||
2.1.16:
|
||||
- Implement access time updates (including mtime and ctime).
|
||||
- Implement fsync(2), fdatasync(2), and msync(2) system calls.
|
||||
- Enable the readv(2) and writev(2) system calls.
|
||||
- Enable access via the asynchronous io (aio) API by adding support for
|
||||
the aio_read(3) and aio_write(3) functions.
|
||||
2.1.15:
|
||||
- Invalidate quotas when (re)mounting read-write.
|
||||
NOTE: This now only leave user space journalling on the side. (See
|
||||
note for version 2.1.13, below.)
|
||||
2.1.14:
|
||||
- Fix an NFSd caused deadlock reported by several users.
|
||||
2.1.13:
|
||||
- Implement writing of inodes (access time updates are not implemented
|
||||
yet so mounting with -o noatime,nodiratime is enforced).
|
||||
- Enable writing out of resident files so you can now overwrite any
|
||||
uncompressed, unencrypted, nonsparse file as long as you do not
|
||||
change the file size.
|
||||
- Add housekeeping of ntfs system files so that ntfsfix no longer needs
|
||||
to be run after writing to an NTFS volume.
|
||||
NOTE: This still leaves quota tracking and user space journalling on
|
||||
the side but they should not cause data corruption. In the worst
|
||||
case the charged quotas will be out of date ($Quota) and some
|
||||
userspace applications might get confused due to the out of date
|
||||
userspace journal ($UsnJrnl).
|
||||
2.1.12:
|
||||
- Fix the second fix to the decompression engine from the 2.1.9 release
|
||||
and some further internals cleanups.
|
||||
2.1.11:
|
||||
- Driver internal cleanups.
|
||||
2.1.10:
|
||||
- Force read-only (re)mounting of volumes with unsupported volume
|
||||
flags and various cleanups.
|
||||
2.1.9:
|
||||
- Fix two bugs in handling of corner cases in the decompression engine.
|
||||
2.1.8:
|
||||
- Read the $MFT mirror and compare it to the $MFT and if the two do not
|
||||
match, force a read-only mount and do not allow read-write remounts.
|
||||
- Read and parse the $LogFile journal and if it indicates that the
|
||||
volume was not shutdown cleanly, force a read-only mount and do not
|
||||
allow read-write remounts. If the $LogFile indicates a clean
|
||||
shutdown and a read-write (re)mount is requested, empty $LogFile to
|
||||
ensure that Windows cannot cause data corruption by replaying a stale
|
||||
journal after Linux has written to the volume.
|
||||
- Improve time handling so that the NTFS time is fully preserved when
|
||||
converted to kernel time and only up to 99 nano-seconds are lost when
|
||||
kernel time is converted to NTFS time.
|
||||
2.1.7:
|
||||
- Enable NFS exporting of mounted NTFS volumes.
|
||||
2.1.6:
|
||||
- Fix minor bug in handling of compressed directories that fixes the
|
||||
erroneous "du" and "stat" output people reported.
|
||||
2.1.5:
|
||||
- Minor bug fix in attribute list attribute handling that fixes the
|
||||
I/O errors on "ls" of certain fragmented files found by at least two
|
||||
people running Windows XP.
|
||||
2.1.4:
|
||||
- Minor update allowing compilation with all gcc versions (well, the
|
||||
ones the kernel can be compiled with anyway).
|
||||
2.1.3:
|
||||
- Major bug fixes for reading files and volumes in corner cases which
|
||||
were being hit by Windows 2k/XP users.
|
||||
2.1.2:
|
||||
- Major bug fixes alleviating the hangs in statfs experienced by some
|
||||
users.
|
||||
2.1.1:
|
||||
- Update handling of compressed files so people no longer get the
|
||||
frequently reported warning messages about initialized_size !=
|
||||
data_size.
|
||||
2.1.0:
|
||||
- Add configuration option for developmental write support.
|
||||
- Initial implementation of file overwriting. (Writes to resident files
|
||||
are not written out to disk yet, so avoid writing to files smaller
|
||||
than about 1kiB.)
|
||||
- Intercept/abort changes in file size as they are not implemented yet.
|
||||
2.0.25:
|
||||
- Minor bugfixes in error code paths and small cleanups.
|
||||
2.0.24:
|
||||
- Small internal cleanups.
|
||||
- Support for sendfile system call. (Christoph Hellwig)
|
||||
2.0.23:
|
||||
- Massive internal locking changes to mft record locking. Fixes
|
||||
various race conditions and deadlocks.
|
||||
- Fix ntfs over loopback for compressed files by adding an
|
||||
optimization barrier. (gcc was screwing up otherwise ?)
|
||||
Thanks go to Christoph Hellwig for pointing these two out:
|
||||
- Remove now unused function fs/ntfs/malloc.h::vmalloc_nofs().
|
||||
- Fix ntfs_free() for ia64 and parisc.
|
||||
2.0.22:
|
||||
- Small internal cleanups.
|
||||
2.0.21:
|
||||
These only affect 32-bit architectures:
|
||||
- Check for, and refuse to mount too large volumes (maximum is 2TiB).
|
||||
- Check for, and refuse to open too large files and directories
|
||||
(maximum is 16TiB).
|
||||
2.0.20:
|
||||
- Support non-resident directory index bitmaps. This means we now cope
|
||||
with huge directories without problems.
|
||||
- Fix a page leak that manifested itself in some cases when reading
|
||||
directory contents.
|
||||
- Internal cleanups.
|
||||
2.0.19:
|
||||
- Fix race condition and improvements in block i/o interface.
|
||||
- Optimization when reading compressed files.
|
||||
2.0.18:
|
||||
- Fix race condition in reading of compressed files.
|
||||
2.0.17:
|
||||
- Cleanups and optimizations.
|
||||
2.0.16:
|
||||
- Fix stupid bug introduced in 2.0.15 in new attribute inode API.
|
||||
- Big internal cleanup replacing the mftbmp access hacks by using the
|
||||
new attribute inode API instead.
|
||||
2.0.15:
|
||||
- Bug fix in parsing of remount options.
|
||||
- Internal changes implementing attribute (fake) inodes allowing all
|
||||
attribute i/o to go via the page cache and to use all the normal
|
||||
vfs/mm functionality.
|
||||
2.0.14:
|
||||
- Internal changes improving run list merging code and minor locking
|
||||
change to not rely on BKL in ntfs_statfs().
|
||||
2.0.13:
|
||||
- Internal changes towards using iget5_locked() in preparation for
|
||||
fake inodes and small cleanups to ntfs_volume structure.
|
||||
2.0.12:
|
||||
- Internal cleanups in address space operations made possible by the
|
||||
changes introduced in the previous release.
|
||||
2.0.11:
|
||||
- Internal updates and cleanups introducing the first step towards
|
||||
fake inode based attribute i/o.
|
||||
2.0.10:
|
||||
- Microsoft says that the maximum number of inodes is 2^32 - 1. Update
|
||||
the driver accordingly to only use 32-bits to store inode numbers on
|
||||
32-bit architectures. This improves the speed of the driver a little.
|
||||
2.0.9:
|
||||
- Change decompression engine to use a single buffer. This should not
|
||||
affect performance except perhaps on the most heavy i/o on SMP
|
||||
systems when accessing multiple compressed files from multiple
|
||||
devices simultaneously.
|
||||
- Minor updates and cleanups.
|
||||
2.0.8:
|
||||
- Remove now obsolete show_inodes and posix mount option(s).
|
||||
- Restore show_sys_files mount option.
|
||||
- Add new mount option case_sensitive, to determine if the driver
|
||||
treats file names as case sensitive or not.
|
||||
- Mostly drop support for short file names (for backwards compatibility
|
||||
we only support accessing files via their short file name if one
|
||||
exists).
|
||||
- Fix dcache aliasing issues wrt short/long file names.
|
||||
- Cleanups and minor fixes.
|
||||
2.0.7:
|
||||
- Just cleanups.
|
||||
2.0.6:
|
||||
- Major bugfix to make compatible with other kernel changes. This fixes
|
||||
the hangs/oopses on umount.
|
||||
- Locking cleanup in directory operations (remove BKL usage).
|
||||
2.0.5:
|
||||
- Major buffer overflow bug fix.
|
||||
- Minor cleanups and updates for kernel 2.5.12.
|
||||
2.0.4:
|
||||
- Cleanups and updates for kernel 2.5.11.
|
||||
2.0.3:
|
||||
- Small bug fixes, cleanups, and performance improvements.
|
||||
2.0.2:
|
||||
- Use default fmask of 0177 so that files are no executable by default.
|
||||
If you want owner executable files, just use fmask=0077.
|
||||
- Update for kernel 2.5.9 but preserve backwards compatibility with
|
||||
kernel 2.5.7.
|
||||
- Minor bug fixes, cleanups, and updates.
|
||||
2.0.1:
|
||||
- Minor updates, primarily set the executable bit by default on files
|
||||
so they can be executed.
|
||||
2.0.0:
|
||||
- Started ChangeLog.
