[CentOS] kernel-2.6.9-42.0.2 and LVM

Sep 13 12:18:56 sfe fsck: /dev/VolGroup00/LogVol00 is mounted.
Sep 13 12:18:56 sfe fsck: e2fsck: Cannot continue, aborting.
Sep 13 12:18:56 sfe rc.sysinit: Checking root filesystem failed

I had updated the box a few days ago but I had not rebooted with the new 
kernel. After the reboot, I get the root filesystem is not marked clean 
message and also that it was not mounted read-only. I supplied the root 
password, remounted read-only, did the obligatory fsck and hit ctrl-D.

Guess what? I get the same message! In addition, there were no error 
messages during the fsck to boot.

Anyone else encounter this?
