This cookbook will identify the ephemeral devices available on the instance based on Ohai data. If no ephemeral devices are found, it will gracefully exit with a log message. If ephemeral devices are found, they will be setup to use LVM and a logical volume will be created, formatted, and mounted. If multiple ephemeral devices are found (e.g. m1.large on EC2 has 2 ephemeral devices with 420 GB each), they will be striped to create the LVM.

- Chef 12 or higher
- A cloud that supports ephemeral devices. Currently supported clouds: EC2, Openstack, and Google.

Place the ephemeral_lvm::default in the runlist and the ephemeral devices will be setup.
node['ephemeral_lvm']['filesystem']- the filesystem to be used on the ephemeral volume. Default:'ext4'node['ephemeral_lvm']['mount_point']- the mount point for the ephemeral volume. Default:'/mnt/ephemeral'node['ephemeral_lvm']['mount_point_properties']- the options used when mounting the ephemeral volume. Default:{options: ['defaults', 'noauto'], pass: 0}node['ephemeral_lvm']['volume_group_name']- the volume group name for the ephemeral LVM. Default:'vg-data'node['ephemeral_lvm']['logical_volume_size']- the size to be used for the ephemeral LVM. Default:'100%VG'- This will use all available space in the volume group.node['ephemeral_lvm']['logical_volume_name']- the name of the logical volume for ephemeral LVM. Default:'ephemeral0'node['ephemeral_lvm']['stripe_size']- the stripe size to be used for the ephemeral logical volume. Default:512
This recipe sets up available ephemeral devices to be an LVM device, formats it, and mounts it.
