From 0.9.3 to 0.9.4, Massimiliano Ghilardi 2012-04-15:
all:
* testing IN PROGRESS on 'nilfs2' and 'ocfs2' file systems
* some changes to compile on FreeBSD - still NOT finished!
fsattr:
* new program, used for fallocate() speedup on ext4 file system.
it removes the 'fallocate' flag (actually named 'uninit')
from all files inside an unmounted ext4 file system
fsmove:
* added option --io=prealloc to fallocate() target files
instead of moving them from source to target.
it's much faster and 100% safe, unlike default --io=posix
that incrementally moves source files during work
and cannot move them back in case of 'disk full' errors.
fsremap:
* UNFINISHED: added options --io=prealloc, --mount-point-device=DIR
and --mount-point-loop-file=DIR
used together with fsmove option --io=prealloc:
in addition to the normal setup (i.e. scanning loop file and zero file)
they assume target files (inside loop file) are preallocated
and their contents still reside in the corresponding source
files (inside device)
* FIXME: support replaying preallocation
From 0.9.2 to 0.9.3, Massimiliano Ghilardi 2012-03-27:
fsremap:
* added automatic checkpointing to persistence file
* new option '--resume-job=NUMBER' to resume interrupted jobs
from persistence file. works even if job was interrupted
by power failure, kill -9, or similar catastrophic events
* default directory for secondary storage and log files is now
/var/tmp/fstransform/fsremap.job.<N>
to better conform with FHS
* changed all options '--OPTION ARG' to '--OPTION=ARG'
to conform with GNU guidelines
* renamed option '--umount-cmd CMD' to '--cmd-umount=CMD'
to use same convention as fstransform
fstransform:
* added cleanup in case of errors
* now works also if device to transform is not mounted
* default log file is now /var/tmp/fstransform/fstransform.log.$$
to better conform with FHS
* added options '--list-source-file-systems' and '--list-target-file-systems'
simplifies integration with other programs (gparted...) as they do not need
to guess which file systems combinations are supported by fstransform
From 0.9.1 to 0.9.2, Massimiliano Ghilardi 2012-03-08:
all:
* added explicit copyright statement to all source files
fsmove:
* added program description to '--help' output
fsremap:
* added check that last device block to be written is actually writeable.
Reason: at least on Linux, if a filesystem is smaller than its
containing device, it often limits to its own length the writable blocks
in the device.
* added program description to '--help' output
fstransform:
* renamed 'fstransform.sh' to 'fstransform'
* added check that source and target file systems are among the
tested ones: minix ext2 ext3 ext4 reiserfs jfs xfs
* added options '--help' and '--force-untested-file-systems'
From 0.9.0 to 0.9.1, Massimiliano Ghilardi 2012-02-13:
fsremap:
* fixed build errors on some Linux flavors (typically rpm-based ones)
* fixed internal error on 32-bit platforms while remapping devices > 4GB
fstransform:
* option '--show-time' is now enabled by default,
use '--show-time=no' to disable
From 0.3.7 to 0.9.0, Massimiliano Ghilardi 2012-02-06:
all:
* replaced Eclipse-generated makefiles with automake+autoconf ones.
new 'configure' script also autodetects required C functions,
headers and types
* added warning to README about transforming to 'xfs'
a device more than 90% full
fsmove:
* added progress report and estimated time left
fsremap:
* zero-file is now optional. if not specified, fsremap performs
an irreversible remapping
fstransform:
* added option '--show-time' to print time-of-day before each message
* added option '--irreversible' to skip creating zero-file
fstransform and fsremap:
* added option '--no-questions' to run automatically without asking
any confirmation.
* added safety checks for devices with odd-sized last block:
now fstransform creates a loop-file with length = device size
_rounded_down_ to file-system block size,
and fsremap refuses to run if loop-file length exceeds device size
_rounded_down_ to file-system block size
From 0.3.6 to 0.3.7, Massimiliano Ghilardi 2012-01-21:
fsremap:
* fixed a bug in the routine to show progress percentage.
This bug cause fsremap to crash while remapping the device,
leaving your data UNUSABLE.
For this reason, PLEASE DO NOT USE FSTRANSFORM VERSION 0.3.6
From 0.2.8 to 0.3.6, Massimiliano Ghilardi 2012-01-21:
fsmove:
* added periodic checks for enough free space in both the source
and target file-systems
fsremap:
* improved the routine to show progress percentage
This routine was found to be bugged and crash while remapping
the device, leaving your data UNUSABLE.
For this reason, PLEASE DO NOT USE FSTRANSFORM VERSION 0.3.6
* added check and workaround for device lengths not multiples of block size
* added check and workaround for incomplete information sometimes returned
by ioctl(FS_IOC_FIEMAP)
fstransform:
* added script 'fstransform.sh', it executes automatically
all the steps needed to perform a full file-system transformation
