Cannot mount volume

[heobmartin]

Hello everyone !

I have three partitions in my disk (Ubuntu, Debian, and Home).

When booting from Ubuntu I can perfectly get access to Debian partition and home partition. But when I try to access Ubuntu or home partition from Debian I receive this message: "Cannot mount volume. You are not privileged to mount this volume."

Can somebody out there help me to find the solution to this problem?

Thanks!

You need to first create a mount point (directory) in Ubuntu as root user: mkdir /mnt/debian
then you need to mount it using the mount command, also as root., Example:

mount -t ext3 /dev/sdX /mnt/debian

If you do not use "ext3" type filesystem you will need to change that and the "sdX" will need to be replaced with whatever partition Debian is on.

Did you gain root privileges?
Execute su - command and then mount partition.

su -
mkdir /media/ubuntu
mount -t ext3 /dev/<partition> /media/ubuntu
cd /media/ubuntu
ls

You will have read only access in /media/ubuntu. You have to give ownership of /media/ubuntu to Regular User for write access.

You can use the "user" option in /etc/fstab under Debian to enable userspace mounting of the filesystems, e.g.

/dev/sda2 /mnt/ubuntu auto rw,noauto,user 0 0

As devils casper sort of alludes to, your privileges on the mounted filesystem will depend on file ownerships and modes. If you make sure your UID in /etc/password is the same for your user in both Ubuntu and Debian, you'll have the same privileges in Debian on the Ubuntu stuff as you do in Ubuntu. That takes some forethought; if you just change a UID willy nilly you'll break the file ownerships of the old UID.
