ChrisLet’s get straight to the point:
First you need to find out the device file of the partition you want to automatically mount on start up.
##lsblk ftw
This is done by using a tool called lsblk (list block devices):
Just run
lsblk
in your terminal and you get something like this:
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sda 8:0 0 232.9G 0 disk
├─sda1 8:1 0 139.7G 0 part /home
└─sda2 8:2 0 93.2G 0 part /media/cf/BCKP
sdb 8:16 0 111.8G 0 disk
├─sdb1 8:17 0 3.7G 0 part /boot
├─sdb2 8:18 0 46.6G 0 part /
├─sdb3 8:19 0 476.9M 0 part /boot/efi
└─sdb4 8:20 0 4.7G 0 part [SWAP]
sdc 8:32 0 931.5G 0 disk
├─sdc1 8:33 0 781.3G 0 part /media/cf/IOMEGA
└─sdc2 8:34 0 150.3G 0 part /media/cf/BACKUP
Note down the block device you need.
E.g. I wanted the /media/BCKP to be automounted so I remembered sda2. Simple right?
##Get the UUID
Next thing to do is to get the UUID (Universally unique identifier) of the partition in your case.
This is done by listing all binary files in the /dev/disk dir:
ls -l /dev/disk/by-uuid/
You get something like this:
lrwxrwxrwx 1 root root 10 May 8 17:38 0098f2fe-2eb0-4030-b933-c196e1097fc9 -> ../../sda2
lrwxrwxrwx 1 root root 10 May 8 17:38 3bf7c4e4-72a7-4d9a-b33a-1cd2941fff7f -> ../../sdb4
lrwxrwxrwx 1 root root 10 May 8 17:38 8932949c-6628-45f6-b6d2-9342ec07c7d6 -> ../../sdb2
lrwxrwxrwx 1 root root 10 May 8 17:38 9D59-7184 -> ../../sdb3
lrwxrwxrwx 1 root root 10 May 8 17:38 abde6f6a-df07-4721-96e0-9fab8494531d -> ../../sda1
lrwxrwxrwx 1 root root 10 May 8 17:38 b59d209c-3c19-4e4b-84ff-8eda7480cc89 -> ../../sdb1
lrwxrwxrwx 1 root root 10 May 8 17:38 f6c607e5-bd41-387f-b433-8d89cb7e084f -> ../../sdc2
lrwxrwxrwx 1 root root 10 May 8 17:38 F82C5A272C59E0E4 -> ../../sdc1
I want to automount the partition sda2 so my UUID I have to remember for the next step is 0098f2fe-2eb0-4030-b933-c196e1097fc9
##Editing the fstab
To automount a partition on start up you need to make an entry for that in the fstab file in /etc :
Open this file with an editor of your choice
gedit /etc/fstab
I recommend to backup your fstab.
If you mess it up I will laugh at you.
</disclaimer>
The syntax of a fstab entry is:
<file system> <mount point> <type> <options> <dump> <pass>
You remember your UUID, right? 'cause now you need it, as well as the mounting point you want the partition to be mounted
Let’s say your UUID is 0098f2fe-2eb0-4030-b933-c196e1097fc9
so your new entry at the end of the fstab would be :
UUID=0098f2fe-2eb0-4030-b933-c196e1097fc9 /media/cf/BCKP ext4 errors=remount-ro 0 2
Check the wikipedia article for more info about that.
Remember to append a new line to the end of the fstab!
Super easy automounting of partitions on linux bro!
