fstransform

fstransform is a tool to change a file-system from one format to another. For example, it can change from jfs, xfs, or reiser to ext2, ext3, or ext4. It works in-place and without the need for backup. It currently has been tested on Linux only. It uses a sparse file to create the new file-system image, moves all the files of the existing file-system into it, then remaps the sparse file to the original partition.

Release Notes: This release significantly enhances "fsremap", adding automatic job checkpointing and the ability to resume unfinished jobs from the checkpoints (this means it can now recover from multiple user interruptions, crashes, or even power failures). It also enhances "fstransform", adding the ability to transform a non-mounted device, inserting appropriate cleanup after errors, and adding new options to ease integration with third party tools (such as gparted). Some options have been slightly renamed, and persistent files and logs are now stored in /var/tmp/fstransform/.

Release Notes: This release adds two new safety checks: lthe ast device block to be written by fsremap must actually be writeable, and the source and target filesystems must be among the tested ones. It also renames 'fstransform.sh' to 'fstransform' and adds an explicit copyright statement to all source files. Finally, fstransform now supports the options '--help' and '--force-untested-file-systems'.

Release Notes: This release fixes an internal error while remapping devices larger than 4GB on 32-bit platforms, and fixes build errors on some Linux distributions (typically RPM-based ones).

    Release Notes: This release adds a configure script and portable Makefiles generated by GNU automake. It also includes stricter safety checks for devices whose length is not a multiple of file-system block size, and new --no-questions, --irreversible, and --show-time options to give users more control over fstransform execution. The fsmove program has been improved and now checks for free space at startup, and periodically shows progress percentage and estimated time remaining. Finally, a warning has been added to README with information about transforming an almost-full device to the 'xfs' filesystem.

      Release Notes: This release fixes a serious bug in the routine to show the progress percentage. The bug was introduced in version 0.3.6, so please do not use that version, because it can crash.
