I get this from the latest stable resize2fs:

Parted (again, latest stable) tells me the following:
Using /dev/mapper/my_vol_grp-my_log_vol
(parted) resize 1 0
100% No
Implementation: This ext2 file system has a rather strange layout!
Parted can't resize this (yet).

Similar results from ext2resize/ext2online. This is an ordinary ext3
fs, living inside an LVM2 that has already been increased to
accomodate (used all free extents).. I've resized it down and up
before, though it is possible I am resizing it larger than it has been
before (1.8TB).
Not sure what's up. Any advice welcome; my research in this has me
getting a bit nervous about lvm2 bugs causing loss of data. While I
want a single resilient (via raid 5) volume, I may be willing to ditch
a whole layer of software (lvm2) to get some security.
Surprised noone has hit this before. It turns out that somehow my swap
space disappeared in a system migration. This became more obvious as I
explicitly tried to extend the fs to a lower limit (438390656), where
resize2fs worked for a while, then informed me that it couldn't allocate
some memory.
Add 512mb of swap and problem solved.. never used more than ~100mb of
swap (256mb main memory).
Hope this helps someone.
