How to unmount a Block Storage volume

Reviewed on 13 December 2023Published on 29 November 2019

It is important to unmount (detach) a device from the operating system using the umount command to avoid data loss before removing the Block Storage volume from the machine.

Security & Identity (IAM)

To perform certain actions described below, you must either be the Owner of the Organization in which the actions will be performed, or an IAM user with the necessary permissions.

  • You have an account and are logged into the Scaleway console
  • You have configured your SSH key
  • You have an Instance with an additional Block Storage volume
  1. Connect to your Instance with ssh.
    ssh root@<your_instance_ip>
  2. Unmount the volume to remove it from your current setup.
    root@scw-festive-agnesi:~# umount /mnt/block-volume
  3. Check that the volume is no longer mounted in the system with lsblk.
    root@scw-festive-agnesi:~# lsblk
    sda 8:0 0 23.3G 0 disk
    vda 252:0 0 18.6G 0 disk
    ├─vda1 252:1 0 18.5G 0 part /
    └─vda15 252:15 0 100M 0 part /boot/efi

    Do not forget to edit the /etc/fstab file and delete the line corresponding to your block volume.

If you want to mount the same volume elsewhere, make sure you change the mount point. Refer to the Managing a Block Storage volume page for more information.
