How to unmount a Block Storage volume

Reviewed on 08 June 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):

You may need certain IAM permissions to carry out some actions described on this page. This means:

  • you are the Owner of the Scaleway Organization in which the actions will be carried out, or
  • you are an IAM user of the Organization, with a policy granting you the necessary permission sets
  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 How to mount and use a block volume page for more information.
