Missing ext4 Partition in Places Menu

**ShodanjoDM** · August 29th, 2011

Hi all

I'm using Ubuntu 11.04 in two partitions (/dev/sda1 for standard Ubuntu/Gnome 2 install & /dev/sda4 for Ubuntu + Gnome 3). I could no longer see the /dev/sda4 - labelled as Ubuntu-2 - listed in Places menu since yesterday. And it's also missing from "Computer" in Nautilus.

I still can mount it manually using "sudo mount" command and have already checked the partition, but I want to know how to bring it back to Places menu for convenience sake.

here's my fdisk -l output:

Code:

Many thanks in advance

When you manually mount it does it also add the "Places" menu entry? If so, you probably don't have (and need to add) an entry for the device in /etc/fstab.

If so, please also post the output of

Code:

sudo blkid

so we can get you the correct entry to add

I have to make a new folder in /media for it to appear in Places menu otherwise it won't show up.

For a test, I made a new "Ubuntu2" folder in /media (for not messing with the partition label of "Ubuntu-2" which appeared in Places Menu before - just in case), run "mount /dev/sda4 /media/Ubuntu2" and it appears there.

Here's my blkid:

Code:

/dev/sda1: LABEL="Ubuntu-1" UUID="7154b84c-603b-4c2c-8fd6-ff8064ec323d" TYPE="ext4" 
/dev/sda2: LABEL="Home" UUID="68003286-fab4-47b0-ac43-894d76827d04" TYPE="ext4" 
/dev/sda3: UUID="4350a5f7-a56c-4af4-bff1-3f1f993e22c9" TYPE="swap" 
/dev/sda4: LABEL="Ubuntu-2" UUID="90fb711a-d335-4394-ac45-a230fe26877c" TYPE="ext4" 
/dev/sdb1: UUID="13ac66e0-7308-4f6d-8fdc-93fb4c2b0522" TYPE="swap" 
/dev/sdb2: LABEL="Arch64" UUID="dbffbb35-ba85-4298-b98f-e148f472b1d2" TYPE="ext4" 
/dev/sdb4: LABEL="Home" UUID="acf222db-5aa1-46b7-9ca6-84c72d558d5b" TYPE="ext4"

Don't know if this is related, but the problem appear yesterday after I installed e17, I have removed it but the problem persists.

Try adding your /etc/fstab line then and it should work.

Open /etc/fstab for editing

Code:

gksu gedit /etc/fstab

add the following line at the bottom, save, and exit

Code:

# Ubuntu-2 entry
UUID=90fb711a-d335-4394-ac45-a230fe26877c /media/Ubuntu2 ext4 defaults 0 0

note that "Ubuntu2" is case-sensitive, so ensure that this is the exact same name as the folder you created previously.

Thank you, but I forgot to mention that I'm already familiar with fstab editing. It's not that I want the partition to auto-mount everytime I logged in, I'm just curious about how to bring the "Ubuntu-2" entry back in Places Menu where I can just click to mount and unmount the partition without having to create a mount point in /media first...

But thanks again, much appreciated

Found an "unelegant" solution:

Made a backup of /dev/sda4, re-format it to create a new UUID & re-label it as a new "Ubuntu-2" partition using gparted. And the partition's label appears again on the Places menu.

Since that is another Ubuntu installation's root partition, I have to edit Ubuntu-2's fstab to change / UUID with the new one.

Oh well, atleast it works now

and I'm marking this thread as solved.
