ephemeral_lvm cookbook
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.

node['ephemeral_lvm']['mount_point']
- the mount point for the ephemeral volume. Default:'/mnt/ephemeral'
-
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'

ephemeral_lvm Cookbook CHANGELOG
This file is used to list changes made in each version of the ephemeral_lvm cookbook.
v1.0.9
- Run 'wipefs' on each ephemeral disk erasing any filesystem signatures, avoiding user interaction during lvm commands.
v1.0.8
- Add testing for support of Ubuntu 14.04, CentOS 7.0, and RedHat Enterprise Linux 7.0.
v1.0.7
- Set the fs_passno field to 0 in /etc/fstab to inform fsck that the filesystem used by the ephemeral volumes should not be checked after stop/start.
v1.0.6
- #19: Do not automatically mount the ephemeral LVM since ephemeral volumes are actually ephemeral and will not come back after stop/start.
v1.0.5
- Changed a misleading error message where no ephemeral disks were found.
- Update lvm cookbook dependency to
1.1.x
.
v1.0.4
- Pull Request #13: Fixed a bug where
fix_device_mapping
was returning the output ofChef::Log.warn
instead ofnil
if it could not find the ephemeral device (@autrejacoupa)
v1.0.3
- Pull Request #9: Debian is now added as a supported platform (@drywheat)
- Make sure cloud specific node area is available before accessing it
- Pull Request #11: Added support for all EC2 instance types (@drywheat)
v1.0.2
- Updated README
