Fedora 13 to 14 upgrade lvm problem

[mojoteri]

I am trying to upgrade a machine from F13 to F14. When I try it indicates the LVM is inconsistent. I have booted the F14 live, mounted the volumes, done fsck. No problems. I have also use the F14 live and passed lvm pvck and vgck with no problems.

The setup is a 500G drive as /boot (Don't ask, but I won't have any future upgrade problems with /boot),
lv_root is two physical drives, and there is a lv_swap on one of them. I also have a vg_ams with another lv_ams which is mounted after boot.

Any suggestions appreciated,
Morris
