Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

ephemeral_lvm cookbook

Cookbook
Release
Build Status

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.

Github Repository: https://github.com/rightscale-cookbooks/ephemeral_lvm

Requirements

  • Chef 11 or higher
  • A cloud that supports ephemeral devices. Currently supported clouds: EC2, Openstack, and Google.
  • Cookbook requirements
  • Platforms
    • Ubuntu 12.04
    • CentOS 6

Usage

Place the ephemeral_lvm::default in the runlist and the ephemeral devices will be setup.

Attributes

  • 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
