Hey there, @julianbroudou,

So, I recreated the answer to the other question and it seems it did not work for me either. However, I tried another method (from Terraform docs) and it did the job just fine!

Instead of doing a whole new block of digitaloceanvolumeattachment, you can simply add the following line in your digitalocean_droplet block. It goes like this:

volume_ids = [“${digitalocean_volume.VOLUME_NAME_HERE.id}”]

We have an array of volume IDs (in my case only 1 element) which is doing the same thing as digitaloceanvolumeattachment.

In short, I would recommend deleting the digitaloceanvolumeattachment block, and instead simply include the volume_ids argument in your digitalocean_droplet block.

I hope this helps, and please let me know if that solved your issue!

Best,
Dennis

Using the volumeids = [“${digitaloceanvolume.VOLUMENAMEHERE.id}”] approach had the same undesired results for me. The volume is successfully attached to the droplet, however it is not mounted on the file system.

I assume it was mounted under the “/mnt” directory for you?

For anyone looking for an answer, I got it to work using a null_resource with a provisioner. The scripts to actually mount the volume are somewhat configurable.

resource "null_resource" "node" {
  count     = var.volume_size == 0 ? 0 : var.node_count

  depends_on = [digitalocean_volume_attachment.node]
  provisioner "remote-exec" {
    connection {
      host = digitalocean_droplet.node[count.index].ipv4_address
      port = 22
      user = "root"
      type = "ssh"
      private_key = var.private_key
    }
    inline = [
      "sudo mkfs.ext4 /dev/disk/by-id/scsi-0DO_Volume_${digitalocean_droplet.node[count.index].name}",
      "mkdir -p /mnt/${digitalocean_droplet.node[count.index].name}",
      "mount -o discard,defaults,noatime /dev/disk/by-id/scsi-0DO_Volume_${digitalocean_droplet.node[count.index].name} /mnt/${digitalocean_droplet.node[count.index].name}",
      "echo '/dev/disk/by-id/scsi-0DO_Volume_${digitalocean_droplet.node[count.index].name} /mnt/${digitalocean_droplet.node[count.index].name} ext4 defaults,nofail,discard 0 0' | sudo tee -a /etc/fstab"
    ]
  }
}
