Using block storage is almost like attaching a USB drive to a laptop. It shows up on your Droplet as a separate drive. That said, you can mount the block storage /home/www-data and store your data there.
The first step would be to move the existing data:
- mv /home/www-data /home/www-data-backup
Next, when you are following the configuration instructions provided in the control panel, replace the instances refrencing /mnt/ with where you really want to mount the volume. For example, if you named the volume volume-nyc3-01 the instructions will suggest you mount it to /mnt/volume-nyc3-01. Instead use: /home/www-data
like so:
- sudo mkdir -p /home/www-data
- sudo mount -o discard,defaults /dev/disk/by-id/scsi-0DO_Volume_volume-nyc3-01 /home/www-data
- echo /dev/disk/by-id/scsi-0DO_Volume_volume-nyc3-01 /home/www-data defaults,nofail,discard 0 0 | sudo tee -a /etc/fstab
Next, we’ll make sure that the new block storage backed directory has the same permissions and ownership as the old directory:
- sudo chown -R --reference=/home/www-data-backup /home/www-data
- sudo chmod -R --reference=/home/www-data-backup /home/www-data
Finally, after verifying everything works as expected, you can remove the old directory to free up the space on your Droplet’s local drive.
