Synopsis

Configure multipath to detect multiple paths to devices for fail-over or performance reasons and coalesces them.

This module implements the following elements:

  • Puppet classes:

    • multipath
    • multipath::common
    • multipath::common::debian
    • multipath::common::redhat
    • multipath::params
  • Puppet definitions:

    • multipath::blacklist
    • multipath::device
    • multipath::path

All these components are configured through a set of variables you will find in manifests/params.pp.

Note: the various operations that can be conducted from this repository are piloted from a Rakefile and assumes you have a running Ruby installation. See docs/contributing.md for more details on the steps you shall follow to have this Rakefile working properly.
