For example, the 
/etc/fstab
 file after adding an entry for 
/dev/sdb
 would look 
similar to the following:
Figure 9.9: The /etc/fstab file after adding a new entry to it
In my example, I created a comment line with a little note about what the extra 
volume will be used for (
Extra storage
). It's always a good idea to leave comments, 
so other administrators will have a clue regarding the purpose of the extra storage. 
Then, I created a new line with the UUID of the volume, the mount-point for the 
volume, the filesystem type, 
defaults
 option, and a 
dump
/
pass
 of 
0
 and 
0
.
The 
defaults
 option I've not mentioned before. By using 
defaults
 as your mount 
option in 
fstab
, your mount will be given several useful options in one shot, without 
having to list them individually. Among the options included with 
defaults
 are the 
following, which are worth an explanation:
• 
rw
: Device will be mounted read/write
• 
exec
: Allow files within this volume to be executed as programs
• 
auto
: Automatically mount the device at boot time
• 
nouser
: Only 
root
 is able to mount the filesystem
• 
async
: Output to the device should be asynchronous
