Let me remind people that on RHEL5,
running e2fsck on an ext4 filesystem will actually destroy data!
use fsck, which runs either e2fsck or e4fsck when e4fsprogs is
installed. On newer systems, where ext4 support is not tacked on
as e4fsprogs, e2fsck handles both (but is it still a good habit to
use fsck to run the proper checker).

#this is where I would get psyched , i did the
same thing to all my ext2/3
filesystems and have extended file systems
online without an issue for
years ..but did I fforget the file system type
this time , yes indeed I for
got we have started doing ext4 on all our new
servers and didn't realise
ext4 fancies it's own bells and whistles ..
I ran the all new resize4fs as suggested by
Stuart , and it made my day in
fact it made for the whole week's frustration
resize4fs 1.41.12 (17-May-2010)

Performing an on-line resize of /dev/vg0/logs
to 37408768 (4k) blocks.
