[Hampshire] LVM problems

Hi all,

Apologies for the length of this email, there's a fair bit of output.

I'm having a problem with LVM that I'm hoping someone here can help
solve. My machine is a Thinkpad T400, about six months old, on which I
installed Ubuntu Lucid 32-bit using LVM. I noticed the problem just
before I upgraded to Maverick on Sunday and the problem still exists
post-upgrade.

Basically, LVM complains when I try to create a new logical volume
greater than 8GB. Creating a test partition of 9GB (lvcreate -L9GB -n
test pooky_vg) gives this output:

device-mapper: resume ioctl failed: Invalid argument
Unable to resume pooky_vg-test (252:6)
/dev/pooky_vg/test: write failed after 0 of 4096 at 0: No space left
on device
Logical volume "test" created

with this message in the logs:

Oct 26 09:44:21 pooky kernel: [ 2623.089006] device-mapper: table:
252:6: sda5 too small for target: start=226451840, len=18874368,
dev_size=244137984

I know there is plenty of space left so the message appears bogus, and
the new logical volume does appear to be created. Does anyone know what
could be causing the problem, and if the created volume is actually safe
to use?

The following output is from fdisk, pvdisplay, vgdisplay and lvdisplay
prior to the lvcreate command and also the lvdisplay snippet for the
test volume after lvcreate.
