Your first message says you have the problems on the lv mounted at 

 >/dev/raid_vg0/raid_lv0  /mnt/raid      ext3    defaults        0 0

then later

If you mean that /var is a separate lv in your raid_vg0 volume group, 
then just umount /mnt/raid and run your fsck on /dev/raid_vg0/raid_lv0.

If you have services that live in or depend on /mnt/raid being mounted, 
stop all those services first. Or init 1 to single user console.
