Mount Drobo on Raspberry Pi

On the Drobo

  1. Install the NFS app.

  2. In your Drobo Dashboard, under "Share Settings", make sure the directory you want to share is accessible to "Everyone".

On the Raspberry Pi

  1. Create a mount point: mkdir Common, where "Common" is the name of the directory you want to share (could be "Downloads", "raspi", whatever you want; I used "Common").
