Introduction
The configuration file /etc/fstab contains the necessary information to mount the disk. This file comes read at the start of the system and can be modified only by root user.
Content of file
It is possible to visualize this file with the following command:
cat /etc/fstab
or alt-f2 and enter:
gksu gedit /etc/fstab
The result of the previous command will be similar to following:
# /etc/fstab: static file system information. # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc defaults 0 0 # /dev/hda1 UUID=12102C02102CEB83 /media/windows ntfs silent,umask=0,locale=it_IT.utf8 0 0 # /dev/hda2 UUID=cee15eca-5b2e-48ad-9735-eae5ac14bc90 none swap sw 0 0 # /dev/hda3 UUID=98E0-6D24 /media/dati vfat defaults,utf8,umask=007,uid=0,gid=46,auto,rw,nouser 0 0 # /dev/hda4 UUID=0aa86c61-0df9-4f1a-8b0b-34abbee6b769 / ext3 nouser,defaults,errors=remount-ro,atime,auto,rw,dev,exec,suid 0 0 /dev/hdc /media/cdrom0 udf,iso9660 user,atime,noauto,rw,dev,exec,suid 0 0
Each no-commented line is composed by six fields:
| fields | description |
| file system | it indicates the devices that contain a file system |
| mount point | it indicates the directory (or mount point) from which it will be possible to approach the content of the device (for the swap is not demanded the mount point) |
| type | type of file system |
| options | options of access to device (the command "mount") |
| dump | turn ON/OFF the backup of file system (the command "dump"). This option is obsolete. |
| pass | turn ON/OFF the control of coherence of the disc (the command "fsck") |
To get a list of all the UUID's use this command:
ls -l /dev/disk/by-uuid
