according to the output of df, yes.
This may not be the only problem you have, it's always my firswt port of call 
when dealing with filesystem labels though.
incidentally, my first tactic would have been to try the edit in 
in /boot/grub/grub.conf - the kernel takes the root= argument from settings 
in there. This is the point at which your boot is failing.
/etc/fstab is not read for a while after that (by /etc/rc.d/rc.sysinit if you 
need to know).
let us know if it makes any difference to your boot process.
