[linux-lvm] LVM Broken on boot.

[Terry Rigby]

Well, I might be somewhere now but I might have also screwed up all my data on 
the device.  I fixed the initial problem and ended up having to basically 
start fron scratch to create the LV again.  I didnt format anything, the only 
thing I did havnt to do with a filesystem was to do resize_reiserfs 
-f /dev/4474/storage.  All went fine except when I try to mount the device. 

mount /dev/4474/storage (setup in my fstab)

mount: wrong fs type, bad option, bad superblock on /dev/4474/storage,
       or too many mounted file systems

:(  Dont know where to go from here
