Linux change mount point

How to set default mount point? [duplicate]

You could edit the /etc/fstab file in a text editor like such as gedit or subl, or you could just do this:

1. Make sure the Hard Drive is connected.
2. Open Disks
3. Click on the Hard Drive you want to modify.
4. Click on the Partition you want to modify.
5. Click on the gear icon
6. Click on Edit Mount Options
7. Move the Automatic Mount Options slider to Off
8. Type in the path you want the Partition mounted too in the Mount Point text box.
9. Click the OK button.
10. Type in the super-user password. This will make the necessary changes to the /etc/fstab file for you.

Thank you very much, forgot to mention i need shell commands since I can only connect via SSH. Any suggestions?

If you log in from a Linux machine with the -Y option, you should be able to just run the GUI application on your local machine. 1. Type ssh -Y user@remoteIPAddress 2. Type gnome-disks to open the GUI app on your local machine, well actually it opens on the remote machine, but sends the GUI info to your local machine.

following this in 2023 with Ubuntu 23 the slider in step 7 is now labeled «User Session Defaults». I’d also add that once this is done, for the changes to take affect you should click the Stop icon to unmount (next to gear icon of step 5), then the Play icon to remount the drive.

To mount automatically at boot time there is file /etc/fstab . In this file you specified which device should be mounted to mount point . As an example :

$ vim /etc/fstab /dev/sda1 /home/USER-ID ext4 defaults 0 0 

Replace USER-ID with your mount point and ext4 with your file system . For any information about more options in fstab see man fstab .

In systemD there is unit by the name of mount which supposed to be replaced with fstab . Try to mount with systemD may help :

cd /usr/lib/systemd/system cp tmp.mount /etc/systemd/system vim /etc/fstab 

And take your added line out.

cd /etc/systemd/system mv tmp.mount mydata.mount vim mydata.mount 

umount old mounted partition.

systemctl deamon-reload systemctl start mydata.mount systemctl enable mydata.mount

How to PROPERLY change mount point name in Linux

In this tutorial I will share the steps to properly change mount point name in Linux with best practices.

What is mount point in Linux?

A mount point is files to which a new filesystem is attached (i.e. logically mounted) and mounted to a directory on the accessible filesystem. Mount point is an ever-present concept within Linux. As the system itself creates a mount point, there are also mount points created by users.

Mount points created by the system do not change very often. But those created by users are more subject to change.

Note: Changing mount point requires sudo privilege or root user. You can switch to root user with the following command:

Or type sudo at the beginning of the commands you will run in the terminal.

Let’s take a look at «How to PROPERLY Change Mount Point Name in Linux».

Step-1: List Mounted Partitions with Mount Points

In Linux, mount points are listed in several different ways. Let’s show two methods:

Method-1: Using df command

List the mount points with their available spaces using df command.

[root@rocky9 foc]# df -hP Filesystem Size Used Avail Use% Mounted on devtmpfs 712M 0 712M 0% /dev tmpfs 732M 0 732M 0% /dev/shm tmpfs 293M 4.3M 289M 2% /run /dev/mapper/rl-root 17G 1.8G 16G 11% / /dev/vda1 1014M 166M 849M 17% /boot tmpfs 147M 0 147M 0% /run/user/1000 /dev/vdb1 20G 2G 18G 10% /backup 

Method-2: Using mount command

We can alternatively also use mount command to list all the mount points on your Linux server.

[root@rocky9 foc]# mount -l proc on /proc type proc (rw,nosuid,nodev,noexec,relatime) sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime,seclabel) devtmpfs on /dev type devtmpfs (rw,nosuid,seclabel,size=728896k,nr_inodes=182224,mode=755,inode64) pstore on /sys/fs/pstore type pstore (rw,nosuid,nodev,noexec,relatime,seclabel) none on /sys/fs/bpf type bpf (rw,nosuid,nodev,noexec,relatime,mode=700) /dev/mapper/rl-root on / type xfs (rw,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota) selinuxfs on /sys/fs/selinux type selinuxfs (rw,nosuid,noexec,relatime) /dev/vda1 on /boot type xfs (rw,relatime,seclabel,attr2,inode64,logbufs=8,logbsize=32k,noquota) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw,relatime) /dev/vdb1 on /backup type ext4 (rw,relatime,seclabel) 

Step-2: List processes accessing mount point

Once you have identified the partition for which you wish to change mount point name, check if any process is utilizing the /backup mount point. You can see which process is using this mount point with the following command:

[root@rocky9 backup]# fuser -cu /backup /backup: 1223c(root) 

To be able to change mount point name name, we must make sure that no process is using the mount point or mounted partition. Here as you can see there is an active process using /backup partition. So either you can manually exit the process or to forcefully kill the process you can use below command.

Please use this command cautiously as this will close any process using the provided partition, causing a risk of loosing data or even corrupting the partition. It is recommended to gracefully stop the application processes.

[root@rocky9 backup]# fuser -k /backup /backup: 1223c Killed

Step-3: Unmount mount point

Once we know that no other process is using our partition, we can safely unmount the mount point. Anyhow if any process is still using the partition, then umount will fail claiming that the target device is busy .

Use the following commands to unmount the mount point:

[root@rocky9 ~]# umount /dev/vdb1

[root@rocky9 ~]# umount /backup

If you get the following error while unmounting, then as explained earlier it is most likely some user is still using this mount point so please make sure to close or terminal any process using the partition:

[root@rocky9 backup]# umount /backup umount: /backup: target is busy. 

At the end of this stage, you have successfully unmounted the partition but this DOES NOT mean that any of your data on /dev/vdb1 is lost. All your data is still safe and nothing for you to worry about.

Step-4: Change Mount Point Name

Use the mkdir command to create the new mount point:

[root@rocky9 ~]# mkdir /new_backup

Then remount the partition to this new mount point:

[root@rocky9 ~]# mount /dev/vdb1 /new_backup

When you list the mount points again, you can see the new directory.

[root@rocky9 ~]# mount -l /dev/vdb1 on /new_backup type ext4 (rw,relatime,seclabel)

Now you can verify your data to make sure there are no data loss as we have successfully changed the mount point name from /backup to /new_backup .

Step-5: Update /etc/fstab

If you wish to auto-mount your partition post reboot then you must also add or update the existing entry of /dev/vdb1 in /etc/fstab with the new mount point or else your Linux server will fail to boot during reboot stage.

In some Linux distributions, fstab has been replaced with systemd-fstab so you can follow How to mount filesystem without fstab using systemd for more information and steps.

Here is my old /etc/fstab file content:

[root@rocky9 ~]# cat /etc/fstab # # /etc/fstab # Created by anaconda on Sun Jul 17 20:35:50 2022 # # Accessible filesystems, by reference, are maintained under '/dev/disk/'. # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info. # # After editing this file, run 'systemctl daemon-reload' to update systemd # units generated from this file. # /dev/mapper/rl-root / xfs defaults 0 0 UUID=76590820-3a66-498d-83ba-73c6ce457531 /boot xfs defaults 0 0 /dev/mapper/rl-swap none swap defaults 0 0 /dev/vdb1 /backup ext4 defaults 0 0 

Open the file with an application like nano or vi and update this line as follows (new_backup instead of backup):

/dev/vdb1 /new_backup ext4 defaults 0 0

Summary

This article was a guide on how to successfully mount a new mount point on your system. For help with commands used in mount point changes:

[root@rocky9 ~]# mount -h Usage: mount [-lhV] mount -a [options] mount [options] [--source] | [--target] mount [options]  mount  [] Mount a filesystem. 

You can follow the same steps for detailed information about fuser, umount and mkdir commands.

How to Change or Rename a Mount Point in Linux

As a Linux admin, you must have got a request for renaming a mount point. Well, it is fairly easy to rename the mount point name in Linux, but it needs some mount point.

Note: You may have clustering software like Veritas Infoscale or PCS cluster which might be controlling the mount point configuration. This post only discusses cases where no external clustering software is controlling the mount point configuration.

In our example, we need to change the /ORABIN12c mount point to /grid on our server.

Follow below steps to change the mount point name.

$ df -hP Filesystem Size Used Avail Use% Mounted on devtmpfs 126G 0 126G 0% /dev tmpfs 126G 640M 126G 1% /dev/shm tmpfs 126G 4.1G 122G 4% /run tmpfs 126G 0 126G 0% /sys/fs/cgroup /dev/mapper/vg_os-lv_root 296G 52G 229G 19% / /dev/mapper/vg_os2-lv_data 197G 15G 173G 8% /data /dev/mapper/vg_os2-ora12c 50G 18G 30G 38% /ORABIN12c

2. Create a directory with name /grid. This directory will be used to mount.

3. edit the /etc/fstab file, replace /ORABIN12c with /grid in fstab file.

/dev/mapper/vg_os2-ora12c /ORABIN12c ext4 defaults 0 0

/dev/mapper/vg_os2-ora12c /grid ext4 defaults 0 0

4. Check if any process is utilizing the /ORABIN12c mount point. You may have to kill the processes running on this mount point or ask app/DBA team to shutdown the app/DB. The command to check if any process is running:

5. Once you have confirmed that nothing is running on the /ORABIN12c mount point, unmount it using the umount command:

6. Now mount the new mount point /grid

7. Verify if the new mount point is reflected in the df command output:

# df -hP /grid Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_os2-ora12c 50G 18G 30G 38% /grid

Changing the mounting point for logical partitions

When I installed Ubuntu 12.04, I didn’t know how to properly set the mounting points for the partitioned logical drives. So, I just set it randomly. Now when I open the Home folder I cannot see any of the logical drives on the left pane. I tried to change their mounting point but couldn’t. The contents of my fstab file /etc folder is:

# /etc/fstab: static file system information. # # Use 'blkid' to print the universally unique identifier for a # device; this may be used with UUID= as a more robust way to name devices # that works even if disks are added and removed. See fstab(5). # #      proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda1 during installation UUID=691fa0bd-350f-4378-b5c7-82d277dd83c2 / ext4 errors=remount-ro 0 1 # /srv was on /dev/sda8 during installation UUID=753d012e-ac3c-42fd-b388-d83115e88d26 /srv ext4 defaults 0 2 # /tmp was on /dev/sda5 during installation UUID=34d8c35a-7900-4acd-988d-880792849673 /tmp ext4 defaults 0 2 # /usr was on /dev/sda6 during installation UUID=4f7f4287-5feb-4b2b-86bb-93fe74905149 /usr ext4 defaults 0 2 # /var was on /dev/sda7 during installation UUID=e2933e36-7906-48ac-b2ac-93500537cd4a /var ext4 defaults 0 2 

My Partitions are mounted at the following locations: /dev/sda5 is mounted at /tmp ; /dev/sda6 is mounted at /usr ; /dev/sda7 is mounted at /var ; /dev/sda8 is mounted at /srv . If I attempt to change the contents of fstab file, it says that only root can change the contents. How do I change the mounting points of the partitions such that they show up in the Home folder?
