I added the following

# Make the partition
bash “format-data-ebs” do
code “mkfs.xfs /dev/xvdh”
end

And it seems to be working

In terms of timing between attaching and mounting, from looking at the aws ebs code in the aws cookbook, it says the attach should block until its done. But I also saw a cookbook that has this in it:

if cluster_ebs_volumes
  cluster_ebs_volumes.each do |conf|
    bash "Wait for ebs volumes to attach" do
      not_if{ File.exists?(conf['device']) }
      code <<EOF
  echo #{conf.to_hash.inspect}:
  i=1
  while true ; do
    sleep 2
    echo -n "$i "
    i=$[$i+1]
    test -e "#{conf['device']}" || continue
    echo "`date` #{conf['device']} mounted for #{conf.to_hash.inspect}" >> /tmp/wait_for_attachment_err.log
    ls -l /dev/sd* >>  /tmp/wait_for_attachment_err.log
    mount          >>  /tmp/wait_for_attachment_err.log
    sleep 5
    break;
  done
  true
EOF
    end
  end
end

Also, I am running into a error where the system doesn’t see the volumen as attached by the time it tries to mount it.
