Please, when posting questions here, don't quote quite so much
unnecessary stuff as the man page output you attached in your email.
It just makes it harder to see your actual question.

Sounds like you were bitten by a kernel bug in the 2.4.10 kernel which
SuSE based their 7.3 release on.  That kernel sometimes forgets to
write back data to disk --- in particular, if user space tools (such
as tune2fs) and a kernel filesystem (such as ext2) are touching the
same disk block, data gets lost.  In this case, that means that the
tune2fs used to upgrade a live, mounted filesystem to ext3 will get
undone after the reboot.

I think SuSE issued a kernel errata for this --- upgrade your kernel,
run e2fsck and try again.  Please do let us know if it still fails.
