How to unmount a Block Storage volume

Unmounting a volume means detaching it from the operating system so it is no longer accessible. You can do this if you want to stop using it, prevent data corruption, or plan to detach it from your Instance and attach it to another. This page shows you how to unmount a volume from the operating system using the umount command.

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
• Created an SSH key
• Created an Instance with an additional Block Storage volume

1. Open a terminal and use the following command to connect to your Instance. Make sure that you replace <your_instance_ip> with your Instance’s IP. You can also find the SSH command in your Instance’s Overview tab in the Scaleway console.

   ssh root@<your_instance_ip>
   

2. Use lsblk to check where your volume is mounted. You should see an output similar to the following:

   root@scw-heuristic-shtern:~# lsblk
   NAME    MAJ:MIN RM  SIZE RO TYPE MOUNTPOINTS
   sdb       8:0    0 18.6G  0 disk /mnt/block-volume
   

3. Unmount the volume to remove it from your current setup. Replace /mnt/block-volume with your mount point.

   umount /mnt/block-volume
   

4. 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
   sdb       8:0    0 18.6G  0 disk
   

   Important

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