I think I found what happened to it:

Its fragmentation performance in relation to vfat is irrelevant. Read the works
of the folks at MIT who wrote EXT2. It *will* fragment over time, just not
quite as bad as some other "modern" filesystems. The worst fragmentation
scenario is appending large files over time. And guess what I have stored on
one of my EXT2 filesystems? Yes, you guessed it, mbox files. I keep all my
mail, all list mail, including debian-user, in mbox files (dovecot). They're
only a combined 200MB at this point, but they will only continue to grow, and
continue to become more fragmented. Thus, I started looking for a defrag tool
for EXT2. It appears that Debian removed it from the distro for fear that ppl
would use it on EXT3/4 filesystems and corrupt them as e2defrag only works on
EXT2. It's apparently not been updated to work with the journals and other data
structures of EXT3/4.
Luckily I've got a dedicated /home partition where these mbox files are stored.
So worst case scenario I can just create a new XFS partition in my unallocated
space and move everything over. XFS has a non-destructive online defragger, and
it's a superior filesystem to EXT2/3/4, Resiser, and JFS anyway.
fact XFS has some really nice management tools, light years ahead of EXT2/3/4
I love having so many good choices available to solve a (potential) problem.
