How to unmount a Block Storage volume

Reviewed on 02 June 2021Published 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.

Requirements:
  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
    NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
    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
    Important:

    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.
