GNOME Disks Auto-Mount Guide

GNOME|120x120, 50%

This comes pre-installed on GNOME images.

Deprecation notice

19/02/2024 ~ If you are using the :testing branch, this procedure is no longer needed as by commit e25e48b. media-automount-generator will handle automounting in non-removable devices (BTRFS and ext4 supported only).

Partitions will be mounted under /run/media/media-automount/PARTITION_UUID.
You can place a custom named shortcut to the partition with:

sudo ln -s /run/media/media-automount/PARTITION_UUID /mnt/CUSTOM_NAME

Instructions

GNOME_Disks|690x463, 75%

  1. Open GNOME Disks (gnome-disk-utility)
  2. Locate the disk and partition you want to mount
  3. Click the cog icon on the partition
  4. Select "Edit Mount Options"
  5. Turn off "User Session Default"
  6. Check: "Mount at system startup" and "Show in user interface"
  7. In the space where this is no label: nosuid,nodev,nofail,x-gvfs-show, (refer to the correct filesystem below for more options)
  8. /var/mnt/games (or whatever directory you made)
  9. auto
  10. Select "Take Ownership"

  11. Open the terminal to test the mounts by running the command:

    sudo systemctl daemon-reload && sudo mount -a

  12. If no errors appeared then it should be safe to reboot.

If an error occurs, then research the error and undo what you did and try again.

Also a Display Name should be added too. Name it whatever you want it to be identified as.

Filesystem Arguments

Warning

If a drive is formatted, then do not remove it from /etc/fstab, so the "nofail" option is a must to avoid issues with booting.

GNOME_Edit_Mount_Options|690x465, 75%

GNOME_Mount_Options|549x500, 75%

BTRFS:

defaults,compress-force=zstd:3,noatime,lazytime,commit=120,space_cache=v2,nofail

Ext4:

defaults,noatime,errors=remount-ro,nofail,rw,users,exec

NTFS:

defaults,noatime,nofail,rw,users,exec

Note

Bazzite does not support NTFS. Using the NTFS filesystem will lead to a lot of issues and should be avoided.

Permissions for the drive

sudo chown $USER:$USER /var/mnt/games

Advanced Options (Not required for most setups)

Warning

Change at your own risk!

Information about compression:

3 is a good balance, older CPUs should use 1.

Information about subvolumes:

use subvol=name as an option, KDE and GNOME Disks let you only mount 1 subvolume through the GUI, you can mount the root with subvol=/ if a default subvolume is configured in the filesystem

Installing GNOME Disks on non-GNOME images

If you would like to install this, then it can be layered to your system by entering in a terminal:

rpm-ostree install gnome-disk-utility

Reboot your system after it has finished installing the terminal.
