Nope, I made sure to dismount anything mounted under /mnt/sysimage (inc. 
  boot/). I have since been able to copy the data by using the SysRescCD 
and then using EVMS to simply look at the partitions and then saving out 
and mounting /dev/evms/lvm/<vg>/<lv> but after restoring and rebooting 
it would kernel panic still thinking that '/' was ext3 despite editing 
'/etc/blkid.tab' and '/etc/fstab'.

I am trying now to figure out how to properly use 'chroot /mnt/sysimage' 
followed by 'lvcreate_initrd' to write a new boot loaded but despit 
double checking that the file name was right Grub still fails to find 
the file...

Quite an ordeal but I am making progress, slowly.

Thanks for your reply! Any other tips by chance?
