Unmounting a Block Storage volume

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 your machine.

Before you start

To complete the actions presented below, you must have:

A Scaleway account logged into the console
Owner status or IAM permissions allowing you to perform actions in the intended Organization
An SSH key
An Instance with an additional Block Storage volume

Open a terminal and connect to your Instance with ssh. Make sure you replace <your_instance_ip> with your Instance’s public IP.

ssh root@<your_instance_ip>

Use the following command to unmount your volume and remove it from your current setup. Make sure you add your own values.

umount /mnt/block-volume

Check that the volume is no longer mounted in the system with lsblk. An output similar to the following should display.

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

Make sure you edit the /etc/fstab file and delete the line corresponding to your volume.

You can mount the same volume again at any time. Refer to the dedicated documentation to mount and use a block volume for more information.
