The entry for UID=359f5eea-47cb-42c4-b96e-974b6f07ad19
is for swap. 

Here is my /etc/fstab.

#
# /etc/fstab
# Created by anaconda on Tue May 29 12:02:11 2012
#
# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info

UUID=e082b796-2fc7-449b-95d8-a39ef6a29891 / ext4    defaul ts        1 1
UUID=f2ed8f21-da63-4def-a674-afdc90e448c5 /home ext4    defaults 1 2 
UUID=d0b7bacc-879a-4b34-9ddd-76f438a28c5d /usr/local ext4
defaults        1 2 UUID=359f5eea-47cb-42c4-b96e-974b6f07ad19 swap
swap    defaults 0 0

What should I be doing?

Many thanks again!
