how i am having problem to mount ext4 partition on startup.

[FurqanHanif]

i made an ext4 partition and name it software. after creating partition successfully i go to "Disks" from menu and set the partition to mount on startup. but after restarting my system an error displayed on boot screen which is "unable to monunt software press s for skip or m for manual recovery" so why i am having problem with ext4 mounting on startup. in the other hand i set ntfs partition to mount on startup it successfully mount so why i am having problem with ext4. i am using linux mint 14 nadia cinnamon. thanks in advance... (sorry for my English).

Did you add that partition to fstab? If so, please post the result of this terminal command here:

Code: Select all

cat /etc/fstab

here is my fstab file picturre and the disk which i trying to mount on startup is named ubuntu. here is my fstab output.

I need to find out how these partitions are formatted and other info so please post the output of the following command:

Code: Select all

sudo blkid -c /dev/null

And is there any "funny" about these partitions - i.e., eSata, external, RAID, etc ...

Side note: In the mean time stop using the "Disks" utility.

Well, I've decided to try something different and actually investigate some things before posting

I don't use utilities to add to or modify fstab so I didn't realize what's happened to the "DIsks" utility ( gnome-disk-utility ). I created an ext4 partition and used it to create an entry in fstab to have it automount. It defaults to these sets of options:

nosuid,nodev,nofail,x-gvfs-show

Why does it do this? A complete breakdown of adult supervision over the developers in Gnomlandia would be my guess but I don't know for sure yet.

This thing is so messed up that it has it's own set of bug reports:

All I can suggest is to have this partition mount they way your grand pappy would have mounted it. If the partition in question is this one:

/dev/disk/by-label/ubuntu /mnt/ubuntu auto nosuid,nodev,nofail,x-gvfs-show 0 0

[1] If you currently have this partition mounted unmount it:

Code: Select all

sudo umount /mnt/ubuntu

[2] I don't know if "Disks" created the mount point or not so create it yourself - worst case it will tell you it already exists:

Code: Select all

sudo mkdir /mnt/ubuntu

[3] Edit /etc/fstab directly with a text editor as root:

Code: Select all

gksu gedit /etc/fstab

[4] Change this:

/dev/disk/by-label/ubuntu /mnt/ubuntu auto nosuid,nodev,nofail,x-gvfs-show 0 0

To this:

/dev/disk/by-label/ubuntu /mnt/ubuntu ext4 defaults,noatime 0 2

[5] Save the file and run the following command which will test for errors and if there are none will mount the partition with the new instructions:

Code: Select all

sudo mount -a

The command will just come back to the prompt if it could not find any errors.

[6] Verify that the partition is mounted:

Code: Select all

nemo /mnt/ubuntu

If you run into any problems post the output of the following commands:

Code: Select all

sudo blkid -c /dev/null

Code: Select all

mount

Code: Select all

cat /etc/fstab
