[SOLVED] Problem changing partition mount point

peter7089 · 01-21-2017, 05:40 AM

I have a partition sda3 to which i want to change the mount point:

Code:

sboxes@osboxes:~$ mount | grep sda3
/dev/sda3 on /media/osboxes/11e00809-744e-4b0a-a9df-05ad54a0dc13 type ext4 (rw,nosuid,nodev,uhelper=udisks2)

I tried this command to change the mounting point but it didn't worked:

Code:

osboxes@osboxes:~$ sudo mount -t ext4 -o remount,rw  /dev/sda3 /home/osboxes/mnt
mount: /home/osboxes/mnt not mounted or bad option

How to change the mounting point of this partition?

If you want to change the mount point permanently you'll need to change it in /etc/fstab. You also have to make sure that the mount point exists. Have you created /home/osboxes/mnt?
If it's just a temporary mount then again, make sure the folder for mounting exists and do

Code:

sudo umount /dev/sda3
sudo mount /dev/sda3 /home/osboxes/mnt

I run 'sudo umount /dev/sda3' and then 'sudo mount /dev/sda3 /home/osboxes/mnt' and the partition was mounted on /home/osboxes/mnt but if i check the mount points is still shows that partition is also still mounted on '/media/osboxes/11e00809-744e-4b0a-a9df-05ad54a0dc13'

Code:

osboxes@osboxes:/media/osboxes$ mount | grep sda3
/dev/sda3 on /media/osboxes/11e00809-744e-4b0a-a9df-05ad54a0dc13 type ext4 (rw,nosuid,nodev,uhelper=udisks2)
/dev/sda3 on /home/osboxes/mnt type ext4 (rw)

Why is that?

looks like the unmount command failed, what out put did you get from it? you can't usually unmount a disk if there is a file on it in use, try using the 'mountpoint' command to check if the old mount point really has a disk mountedd there.

I think i found what was the problem. I had the partition opened in my file manager (thunar) while i trying to unmount it. I closed the file manager and was able to unmount it.
By the way, what these values mean (rw,nosuid,nodev,uhelper=udisks2)? The previous mount point showed theme and now it shows only 'rw' (read,wtite):

Code:

osboxes@osboxes:/var/cache/apt/archives$ mount | grep sda3
/dev/sda3 on /home/osboxes/mnt type ext4 (rw)

you can check it on the man page of mount

You could also have created a soft link to the mounted partition in your home directory, which is usually easier

Code:

ln -s what where

(See man ln)
