I used auto-mount option in Ubuntu 14.04 for mounting my all drives at startup.

enter image description here

All drives mounts automatically on startup except /dev/sda3. (Let me clarify that /dev/sda3 is ext4 file-system and labeled Ext4).

It gives error on startup and ask S for skip and M for manual mounting.I skipped and try to mount with disk (installed app from dash earlier disk-utility), it gives error:

But If I mount with command: sudo mount /dev/sda3 /media/pandya/Ext4 at startup (By pressing M for manual mount) or after started up (from terminal), then it mounts properly.

Gparted also mounts that drive on /media/pandya/Ext4 Successfully.

I also checked /etc/fstab and entry for /dev/sda3, which is proper

/dev/sda3 /media/pandya/Ext4 auto nosuid,nodev,nofail,x-gvfs-show 0 0

I used same auto-mount options for all drive. Then why only one is not auto-mounting?

  • Is there any information in dmesg? As the error says, try dmesg|tail. – Jos Apr 24 '14 at 6:43

    I found a bug relevant to this issue. As a workaround, edit the fstab to show "comment=x-gvfs-show" instead of "x-gvfs-show". – Jos Apr 24 '14 at 7:00
  • It would be helpful for other users accepting a working answer. Cheers. – Atcold Aug 3 '15 at 17:58
  • @Jos: What does comment=x-gvfs-show do? Or just x-gvfs-show for that matter? I had x-gvfs-show inserted automatically as an option in /etc/fstab when editing (or rather creating) the mount options of an ntfs partition using the application Disk in Linux Mint (probably also an Ubuntu application). – HelloGoodbye Feb 3 '16 at 20:00

As @Jos suggested, this is the bug Bug #1012081: util-linux needs updating to 2.24.2 and can be fixed by adding comment= in front of x-gvfs-show.

Uncheck Show in user interface.

It boots and mounts properly, but is not visible in the nautilus file explorer.

  • This actually worked. Amazing. – gruszczy Nov 14 '14 at 21:57
