Hey I got this problem on my fresh xubuntu 13.10 install

I have a Data device /dev/sda5 which I like to auto-mount it on startup, I added it to the /etc/fstab file

UUID=261ff894-502a-4b5b-8bc7-b53a8ab8e325 /home/linuxer/DATA/   ext4    rw      0       0

The problem is that when the I login and access the folder it's empty!
Although when I echo the command


it says that /dev/sda5 is mounted at /home/linuxer/DATA/ !
So I have to unmount it, and it displays:

umount: /home/linuxer/DATA: not mounted

but on remount, it displays well!

I've got another line in my /etc/fstab

UUID=208A8DE78A8DBA34   /media/win7onsada3      ntfs    rw      0       0

and this one works just fine.. It auto-mounts on startup

I have my system set -up with LVM support activated.
Any help would be appreciated!

edit your question and post the output of sudo blkid and cat /etc/fstab. – Saurav Kumar Oct 29 '13 at 18:26
Done! output added. – Ayman Oct 29 '13 at 18:36
I'm confused with your Dat and Data, dat and Data.. :P Also post the output of sudo lsblk – Saurav Kumar Oct 29 '13 at 18:49
Hope it's less confusing now ;) Done! output added. – Ayman Oct 29 '13 at 18:53
Have you tried using defaults instead of rw in your /etc/fstab? – edwin Oct 29 '13 at 20:07

So the last command shows that your /dev/sda5 partition is not mounted

I don't know what steps did you follow. Let us try to mount it again. So please follow these steps.

  1. First unmount all the partitions by:

    sudo umount -a
  2. Then make a directory Data under /home/linuxer. If already such directory then first remove it,then create:

    sudo mkdir /home/linuxer/Data
  3. Give the permission 777 to the directory Data. You can change the permission according to your need:

    sudo chmod -R 777 /home/linuxer/Data
  4. Now edit the file /etc/fstab. So open in any text editor with root permission and do the changes.

    sudo nano /etc/fstab

    Then remove the line:

    UUID=261ff894-502a-4b5b-8bc7-b53a8ab8e325 /home/linuxer/DATA/   ext4    rw  0   0

    and add this:

    UUID=261ff894-502a-4b5b-8bc7-b53a8ab8e325 /home/linuxer/Data    ext4 errors=remount-ro 0       1

    Press Ctrl+X to close, when prompt to save press Y.

  5. Now mount all the partitions using this command:

    sudo mount -a

Reply if something goes wrong. Your partition should mount automatically when you reboot your system.

Nope... Same problem! I can remount but it doesn't go automaticly on reboot! – Ayman Oct 29 '13 at 19:41
That is why I tested it first before giving the answer. It is working fine for me. I don't know what wrong in your case. Ok last try to change the mount point from /home/linuxer/Data to /media/Data by following same steps. You need to create the directory Data under /media/ and also have to change the file /etc/fstab Reply.. – Saurav Kumar Oct 29 '13 at 19:49

Since your /home is on pass 2 it may not be available as a mount-point when it tries to mount your DATA partition. Either specify pass 3 to the DATA partition or mount the DATA on /data and make a symlink from your home directory.

share|improve this answer
!! Does the 3rd pass even exist? BTW, symlinks will cause me many troubles because many configs on the sda5 require hard links :/ – Ayman Oct 31 '13 at 12:06

From man fstab:

The mountall(8) program that mounts filesystem during boot also recognises additional options that the ordinary mount(8) tool does not. These are: ... and ``showthrough'' which permits a mountpoint to be mounted before its parent mountpoint (this latter should be used carefully, as it can cause boot hangs).
