How can I gain ownership of a partition which mounts on boot up please? Ubuntu 14.04 LTS

Question

I'm a relative newbie. Ive done a bit of systems editing but only by copying scripts and seeing if they work - ie trial and error

I've created a ext4 partition. Gparted confirms (mount point: /media sda2, /mnt/sda2) (label: disk2) and says it is mounted but when I open it up and try to open a folder in it, I get an msg saying I dont not have permissions to view contents.

When ubuntu 14.04 starts up its says disk not ready or not present so I press s for skip

I want to have full access to the disk and its contents - can you help pls? if you start writing scripts, pls give examples and explain what each parameter means.

Thank you for your consideration.

Unable to access “Disk2”

Error mounting system-managed device /dev/sda2: Command-line `mount "/mnt/sda2"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sda2, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so

Answer 1

Many many thanks for all the input - Im truly grateful.

I've managed to resolve all the issues about accessing and mounting "Disk2" etc

I edited fstab thanks to Maythux and commented out the offending lines. Special thanks to user5570 for your patience with my ignorance.

You have lot of confusion in your question?

Did you remove the swap partition and make it ext4 as new partition?!

From your fstab:

swap was on /dev/sda2 during installation

And you say:

I've created a ext4 partition. Gparted confirms (mount point: /media sda2, /mnt/sda2) (label: disk2)

And how would you get two mounting points?!!

(mount point: /media/sda2, /mnt/sda2)

From your fstab

UUID=28e06dd5-f4e6-4e91-8d50-9f93b8863fbb /home/ubpaul/disk2 auto sw,x-gvfs-show,x-gvfs-name=Disk2 0 0

/dev/sda2 /mnt/sda2 auto nosuid,nodev,nofail,x-gvfs-show 0 0

UUID=6e692a08-9b12-4e0a-94f4-209a864d819b /media/sda2 ext4 defaults 0 2

Those are three entries full of mess.

What to do?

First Remove those three lines from your fstab

Now you have to review your configuration

Do you have swap partition? If yes add its entry to the fstab? (according to your fstab you have a swap on /dev/sda2)

Now be sure you create correctly a new partition and format it with ext4, and be sure not to replace swap if you want it already.

Now add the entry of your newly created partition.(note its name from gparted). You can add Entries in fstab either in name such as /dev/sdX or UUID, you can get the UUID running command:

sudo blkid

Also be sure to have one entry in fstab for every partition and with only one mounting point.

The correct syntax to add to fstab:

UUIUUID  /mounting-point ext4   defaults    0   0

Answer 3

Its good that you found the solution to the permission issue.

About the startup issue, try running cat /etc/fstab to inspect your mount settings.

If you are mounting removable media in your /etc/fstab, you can comment that item in the fstab file.

Try to comment out this line in the /etc/fstab

UUID=6e692a08-9b12-4e0a-94f4-209a864d819b /media/sda2 ext4 defaults 0 2

Answer 4

A normal user can not have full access to an ext4 partition, unless you have became root with sudo command.

I guess that you tried to open lost+found folder. This one is a possible duplicate: link. It is somthing like "System Volume Information" in Windows.

You should try to create a directory. It should work with the default mount options.
