I’m going to show you how to mount Linode’s additional storage volumes to your server.
They’re really handy for adding space to your server. Only thing is they don’t add space overall to the server, you mount them to a specific directory (mount-point) and only that directory has more space.
While the storage volume drives are fast enough to run applications, they aren’t as fast as the ones on your server. So I probably wouldn’t try to do heavy php or DB processing off the storage. I would use them only for lower priority items, like maybe backups or media (images & videos).
