[solved]gksudo gedit /etc/fstab not working + mount partitio

[phidias81]

Hello, this is my first Message here, and first Linux ever for me. I have installed Mint 14.1 mate, without windows. I created several partitions for installation, plus a Data partition that I would like to mount (I didn't create \home). I read at least 20 topics to be sure of the procedure (that I will past after) but after creating the mount point, the command gksudo gedit /etc/fstab launched from the terminal is not opening anything. I see "starting administrative application" on the bar, that is closing itself without opening anything. What is wrong?
And also from computer, I cannot see my Data partition. I see a 500 gb HD icon that if I try to mount I get an error message like in the picture


Below in the next message I attach my procedure to permanently mount the partition. I stop at step number 3

This is my gParted screen


[1] Find the correct UUID number for your windows partitions:

Code: Select all
sudo blkid -c /dev/null

In my case: /dev/sda6: UUID="af4f8440-66b3-4001-9708-f9e1d092c8dc" TYPE="ext4"

[2] Create permanent mountpoints for your partitions to live in, in my case:

sudo mkdir /media/Data

[3] Edit fstab as root:

Code: Select all
gksudo gedit /etc/fstab

[4] Add the following lines to the end of fstab, examples:

Code: Select all

UUID=af4f8440-66b3-4001-9708-f9e1d092c8dc /media/Data ext4 defaults,noatime 0 2

[5] If you have already mounted these partitions manually through computer(icon) - unmount them.

[6] Run the following command that will test for errors and if there are none mount the partitions to their new home without requiring a reboot:

Code: Select all
sudo mount -a


[] Once it's mounted take possession of the mounted partition. For example:

Code: Select all
sudo chown /media/Data

[3] Edit fstab as root:

Code: Select all
gksudo gedit /etc/fstab

That's for the Gnome DE. You are using MATE. The step for you is:

Code: Select all

gksudo pluma /etc/fstab

EDIT: This isn't quite right either:

[] Once it's mounted take possession of the mounted partition. For example:

Code: Select all
sudo chown /media/Data

This looks better:

Code: Select all

sudo chown your-user-name /media/Data

Change your-user-name to .. well ... your user name.

Thank you, now the editor opened. I pasted the line and after I executed

Code: Select all

sudo mount -a

and nothing happened. After I also wrote

Code: Select all

sudo chown davide /media/Data

and still nothing happened, so I'm not sure if this is the correct behavior or something is wrong. As far as I understood, after this procedure a new Icon in my desktop was supposed to be created, but I see nothing.
Same as before if I go to computer.
If instead I go to location: /media/Data I see a folder lost+fount with an X and a lock.

[phidias81]

Ok, I guess I did something wrong. Now I tried to restart and Linux is not starting up, I get a black screen and if I press a key I get this message



Now I-m connected from the usb stick. Help

[altair4]

If you are running from the LiveCD or USB in your case locate the /etc/fstab file on the partition that holds Mint and put a # sign in front of the line you added:

#UUID=af4f8440-66b3-4001-9708-f9e1d092c8dc /media/Data ext4 defaults,noatime 0 2

Then see if you can boot into your box again.

If you can please post he output of the following commands:

Code: Select all

cat /etc/fstab

Code: Select all

sudo blkid -c /dev/null

I was able to enter again. So this is what I get

Code: Select all

I guess the problem is that I referred 2 times to #UUID=af4f8440-66b3-4001-9708-f9e1d092c8dc with 2 different moun options? SO maybe I should delete that last line I added, and do binding instead as explained in this post?

Code: Select all

[3] Auto Mount at Boot by creating your own Upstart script:

This is the method I now use by default since I can make sure that the bind operation only happens after the original partition is mounted.

Create an upstart job named "bind-home.conf"

Code: Select all
    gksu gedit /etc/init/bind-home.conf


The content of that file would look like this:

Code: Select all
    # Remount partitions with bind
    #
    description "Bind Data Partition Subdirectories to My Home Directory"

    start on stopped mountall

    script
    mount --bind /Data/Documents /home/altair/Documents
    mount --bind /Data/Downloads /home/altair/Downloads
    mount --bind /Data/Pictures /home/altair/Pictures
    end script


The "start on stopped mountall" insures that the bind commands will not be executed until all system mounts ( i.e., fstab ) are completed.

/dev/sda6: UUID="af4f8440-66b3-4001-9708-f9e1d092c8dc" TYPE="ext4"

You already have this partition mounted:

UUID=af4f8440-66b3-4001-9708-f9e1d092c8dc /data ext4 defaults 0 2

There's no need for this:

#UUID=af4f8440-66b3-4001-9708-f9e1d092c8dc /media/Data ext4 defaults,noatime 0 2

If you want to change the mount point to get an icon on the desktop for this you can get the same affect by creating a launcher so that you don't have to edit fstab again - this is the simplest thing to do:

Right Click the desktop > Create launcher >
NAME: data
COMMAND: caja /data

OR, you can reverse the # sign on the 2 so that instead of this:

UUID=af4f8440-66b3-4001-9708-f9e1d092c8dc /data ext4 defaults 0 2
#UUID=af4f8440-66b3-4001-9708-f9e1d092c8dc /media/Data ext4 defaults,noatime 0 2

You would have this:

#UUID=af4f8440-66b3-4001-9708-f9e1d092c8dc /data ext4 defaults 0 2
UUID=af4f8440-66b3-4001-9708-f9e1d092c8dc /media/Data ext4 defaults,noatime 0 2

Ok, thank you, it works. One last thing: is it normal that if I go to "Computer" I cannot see my Data partition. I see a 500 gb HD icon that if I try to mount I get an error message like in the picture. This link that I create on the desktop, is the only way to access my data partition? In example, if I press "open" somewhere, there is no way to browse to my data partition directly from "places" rather than going to file system>Data?

[altair4]

** I can't explain the error message or why it's showing the icon at all.

** Your /data partition is listed in "Computer". Since it's now mounted it under "File System"

** You can bookmark this mountpoint so it shows up in Caja's left side panel:

caja /data

Then Bookmark it: Bookmarks > Add Bookmark
