I get a 'Permission Denied' error when configuring my block storage volume to mount automatically -- what gives?

A great question! If you're getting that error in particular, it means that you've entered a command into the terminal that actually needs to be added to your /etc/fstab file. No worries though, all you'll need to do is open this file using sudo nano /etc/fstab and add the following line:

/dev/disk/by-id/scsi-0Linode_Volume_MyVeryOwnVolume /mnt/MyVeryOwnVolume ext4 defaults,noatime 0 2

Once you've done so, your volume should mount automatically at boot.
