LVM not recognized after installing 10.04

[Thomas K Gamble]

I upgraded my system to 10.04 via clean install.  I ignored my LVM partitions 
during install figuring I could edit the fstab file after install to remount 
them.  No such luck.  Mount says /dev/vg00/lv0x doesn't exist.  System-config-
lvm sees the volume groups and logical volumes but doesn't find a filesystem on 
the logical volumes.  They are ext4.

Is there anyway to recover these short of recreating everything from scratch 
and restoring from backup?
