LVM boot issue?

[Dave Stevens]

I have a workstation with 2 Seagate SATA drives, the older a 320 with  
F7 and data, now used for backups, and a current 640G with F14.  
Recently the F14 has refused to boot. I am able to boot F7 from the  
older drive but not to much effect, it is so far out of sync with my  
work that it's pretty much useless.

At boot time on the F14 drive I get:

3 logical volume(s) in volume group "VolGroup00" now active
2 logical volumes in volume group "vg_davehost" now active
[OK]

Checking filesystems
/dev/mapper/vg_davehost-lv_root contains a file system with errors,  
check forced.
/dev/mapper/vg_davehost-lv_root: [spinner for progress %]


Then at some time [around 2.5% checked] the system reboots back into  
the same situation and the sequence repeats.

I have booted from a F16 live CD and can see the data on the drive but  
can not seem to get enough access to copy off the data or get around  
the check or get the check to correct the error. Also I don't know the  
result of the check and don't see how to get more info. I can verify  
that the drive is /dev/sde and that sde2 has my data, but I don't know  
how to mount it in a readable way even though nautilus apparently  
does. As liveuser I haven't enough access to see my data or move it.

Suggestions? References?
