mounting problem

Question

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

mount

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!

Solution 1

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.

Solution 2

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.

edit your question and post the output of sudo blkid and cat /etc/fstab.

[Ayman Nedjmeddine]

Done! output added.

[Saurav Kumar]

I'm confused with your Dat and Data, dat and Data.. :P Also post the output of sudo lsblk

[Ayman Nedjmeddine]

Hope it's less confusing now ;) Done! output added.

[Saurav Kumar]

Ok! Give me some time..

[edwin]

Have you tried using defaults instead of rw in your /etc/fstab?

[Ayman Nedjmeddine]

Yes I did @edwin, I used defaults,auto,user ... same problem!

[Ayman Nedjmeddine]

One reply I got on the Google+ community suggests this:"I think the issue is your encrypted partitions are being mounted after the unencrypted ones. Hence even though DATA is mounted the home over rides it." What do you guys think about it?

[Ayman Nedjmeddine]

Nope... Same problem! I can remount but it doesn't go automaticly on reboot!

[Saurav Kumar]

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..

[Ayman Nedjmeddine]

!! Does the 3rd pass even exist? BTW, symlinks will cause me many troubles because many configs on the sda5 require hard links :/
