OK, I started to follow Clark's procedure and when I got to the point of
reformatting partition 4 to jfs, I ran Gparted and it already shows up
as jfs. It's partition 3, with the initrd, that is ext2. D'OH! So, I
guess there is not an issue. I was just confused by the results of "df
-T". I guess the user space just doesn't show up with that command.

Thank you, Clark! That was a lot more straight-forward than I would
have expected. Doesn't the kernel or initrd expect ext2 on partition 4?
By the way, "df -T" on the SBC returns (edited)
Filesystem Type Mounted on
rootfs rootfs /
/dev/tssdcarda4 ext2 /initrd
...
none /initrd/dev
none /initrd/dev/shm
tmpfs tmpfs /dev
I'm assuming that /dev/tssdcarda4 is partition 4 of the SD card, which
would indicate its using ext2. I'll give your procedure a shot and
see what happens.
Thanks again!

I use a USB card reader on a Debian laptop.
1. Mount desired partition, use 'df' to find node:. eg: /media/disk-X
is at /dev/sde4
2. Copy contents: sudo tar cvf sde4.tar ../../../media/disk-X
3. unmount and Re-format to jfs, jffs2, etc.
4. Re-mount and confirm /media/disk-X is still at /dev/sde4
5. Restore content: sudo tar xvf sde4.tar
You might want to check, but I seem to remember that
512mbsd-7400-linux2629-lenny-eabi.dd.bz2 already
uses jfs on partition 4.

Has anyone succeeded in transitioning their Technologic System SBC's
file system to a journaling file system?
I'm using Technologic System's kernel
(linux-2.6.21-ts-src-feb022010.tar.gz) together with their SD card
image (512mbsd-7400-linux2629-lenny-eabi.dd.bz2). I believe that
these use the ext2 file system. I would like to use a more recent
file system to reduce the likelihood of file system corruption during
a hard board reset (such as from a watchdog timer timeout).
[Although, these posts indicate that I may also need to worry about
fsck problems:

I'm a linux newbie, so it took me a while just to get these to work
toget! her, and my experience using other images and patches found
elsewhere have not met with success. So, I would like to continue
using TS's products to the extent possible, but I have no idea how I
would transition them to a later file system.
Does anyone have any experience they would be willing to share?
Thank you,
Don
