I ended up not putting names/labels on them, including the other boot
partition in the /etc/fstab made it so I couldn't access it through the GUI
(file system launcher) so I #'d them out so they look like this:

# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda1 during installation
UUID=f2746f47-5e69-4b03-a5c1-c6c89e6ccdb4 /               ext4
 errors=remount-ro 0       1
# swap was on /dev/sda5 during installation
UUID=e527fee4-9467-430a-8050-bb3f570d8109 none            swap    sw
       0       0
# UUID=5677efe7-4044-45b7-b8b9-9e79b51cb659 /               ext4
 defaults        0       1
UUID=3769e2e8-adde-456c-86e4-0402be737ef6 /media/storage  ext4    defaults
       0       1
UUID=ec787761-11d5-4127-b198-e159bfcd2a6a /media/storage2 ext4    defaults
       0       1
trieli at mythtv:~$

line 3 and 6 are reversed respectively per boot drive.

thanks for all the advice
