Boot into Rescue Mode, choose not to find the root storage, find your LVM volumes with lvm pvscan, lvm vgscan, vgchange -ay VolGroup00 and fsck the filesystems.

Also worth running smartctl -a /dev/sdX on the underlying physical device to see if the disk is OK. That doesn't look good and I'm suspecting a hardware error. Read man e2fsck for the various options too but before you do anything, if the data on this drive is valuable then I would obtain a second physical disk that's at least as large as the original and use the 'dd' command to copy from the broken one to the new one. Use the option conv=noerror so that it continues even over I/O errors on the old disk or, better, use dd_rescue which is a different command and specially designed for recovering data from disks with problems.
