Re: [FC5] Change file system & merge drive without lossing data???

I have no idea whether this actually works, and it is risky under any
circumstances, however you may want to look at the following.  It
won't help you merge the two file systems without substantial work,
since you need to be concerned about overlapping inode numbers, etc.:


anyfs-tools - toolset for recovering and converting filesystems and
              recovering data from a block device.


Convert filesystems

    anyfs-tools anyfs-tools allows a user to convert filesystems. There
    is only one requirement for the existing source filesystem: there
    must be FIBMAP system call ioctl(2) support in the filesystem driver
    (maybe read-only) for Linux OS.

    Currently anyfs-tools supports filesystem conversion to ext2fs/ext3fs
    or xfs, but it's hoped that in future there will be other filesystem
    building support. For this to happen, there must first be interest
    from filesystem maintainers and developers. The advantage of
    anyfs-tools is that it is a convenient tool and does not require
    much free space for saving of all of the meta-data for files ably
    increase the number of users of a particular supported filesystem.

    Generally, the steps to convert an existing filesystem are as follows:

    1) build_it for reading all informaton about the physical location
       of files on a disk and file access permissions, then saving that
       information to an external inode table.

    2) maybe anyfs driver for clear some space for new filesystem.

    3) maybe reblock for changing filesystem blocksize where the
       destination filesystem doesn't support the same blocksize as the
       source one.

    4) Finally, build a filesystem by using build_e2fs or build_xfs.

    The whole converting process maybe automated with using the
    anyconvertfs script.

Thanks bill for something new but it seems bit complicated. Though it
is good for learning, I can't afford to do this right now. I guess I
will use the older method for right now.

Thanks again!
