Get the volume’s mount point with df
if you don’t already know it:
sudo df --human-readable --print-type
The mount point will look like /mnt/volume-sfo2-01
:
Filesystem Type Size Used Avail Use% Mounted on
. . .
/dev/sda ext4 99G 60M 94G 1% /mnt/volume-sfo2-01
. . .
Make sure the volume isn’t in use. If you try to unmount a volume while it’s in use, you’ll get a target is busy
error, so check if any processes are using the mounted filesystem with lsof
:
sudo lsof +f -- /mnt/use_your_mount_point
- Stop any listed processes.
Unmount the volume with umount
.
sudo umount --verbose /mnt/use_your_mount_point
Including the --verbose
flag makes the command output /mnt/your_mount_point unmounted
when it executes successfully. Otherwise, umount
is silent on successful execution.
If you won’t reattach the volume in the future, you can do some additional cleanup:
- Edit
/etc/fstab
to remove any entries referencing the volume. - Delete the mount point:
sudo rmdir /mnt/use_your_mount_point
