How to fix incrementing mount names on reboot in Ubuntu/Linux Mint

#bindvolumes #fstab #linuxmint #mountpoints

TL;DR

To prevent your internet disks from being mounted with incrementing names (e.g., name1, name2) on each reboot, configure static mount points using the /etc/fstab file. This avoids conflicts with services like Docker that use bind volumes.

Context

Each time I restarted my computer running Ubuntu/Linux Mint, my additional disks were mounted with incrementing names. This breaks all symbolic links and history because another service, Docker in my case, uses the path before it is mounted.

Why was this happening? I did not care to check how were the additional internal disks being mounted. I just connected them and started to use them. To be fair, I don't restart my computer that often (around once a year, see the image below), so it took me almost a year to find this situation.

uptime

Long story short, I restarted my computer and many thing did not work anymore, and the mount points were the cause of it.

Steps to Fix the Issue

1. Find the UUID of the Disk

Use the lsblk command to list all block devices and their UUIDs:

lsblk -o NAME,FSTYPE,UUID
Enter fullscreen mode Exit fullscreen mode

You can also use the disk manager in your desktop environment to find the UUID. In my case, KDE, it looks like this:

disk manager kde uuid

Note down the UUID of the disk you want to mount.

2. Edit /etc/fstab

Open the /etc/fstab file with a text editor:

sudo nano /etc/fstab
Enter fullscreen mode Exit fullscreen mode

3. Add an Entry for Your Disk

Add an entry for your disk using its UUID:

UUID=<your-uuid> /mnt/your-mount-point ext4 defaults 0 2
Enter fullscreen mode Exit fullscreen mode

Replace <your-uuid> with the actual UUID and /mnt/your-mount-point with your desired mount point.

4. Understand the fstab Options (optional, most of the time the defaults will work)

  • defaults option : A shorthand for standard mount options, including:
  • rw (read-write)
  • suid (allow setuid bits)
  • dev (interpret device files)
  • exec (allow execution of binaries)
  • auto (can be mounted with mount -a)
  • nouser (only root can mount)

  • async (asynchronous I/O)

  • 0 (dump): This field is used by the dump utility to decide if the filesystem needs to be dumped. 0 means ignore.

  • 2 (pass): The order in which fsck checks the filesystem for errors during boot. 0 means don't check, 1 is reserved for the root filesystem, and 2 is for all other filesystems.

5. Create Mount Points

If you don't have the mount points already, create them:

sudo mkdir -p /mnt/your-mount-point
Enter fullscreen mode Exit fullscreen mode

In my case I did already have them.

6. Mount the Drives

Restart your computer or run the following command to mount the drives immediately:

sudo mount -a
Enter fullscreen mode Exit fullscreen mode

In my case I had to restart the system, as that was the easiest way to get everything normal again.

Side notes

As sidenote, some of the issues I had were:

  • Nextcloud Desktop could not sync anymore, as it did not find the destination folder.
  • The quick accesses on doplhin file manager were no longer correct.
  • all my zoxide paths were broken.

That was enough for me to fix this, as I couldn't take it anymore. :)
