This adds defined anchor points for external modules to hook into the software install, config and service dependency chain. This allows external modules to manage software installation (virtualenv, containers, etc) and service management (pacemaker) without needing rely on resources that may change or be renamed.

# follow the instructions for creating a loopback device
|
|
# for storage from: http://swift.openstack.org/development_saio.html
|
|
#
|
|
#
|
|
# creates a managed loopback interface
|
|
# - creates a file
|
|
# - formats the file to be an xfs device and mounts it as a loopback device at /srv/node/$name
|
|
# - sets up each mount point as a swift endpoint
|
|
# === Parameters:
|
|
#
|
|
# [*base_dir*]
|
|
# (optional) The directory where the flat files will be stored that house
|
|
# the file system to be loop back mounted.
|
|
# Defaults to '/dev', assumes local disk devices
|
|
#
|
|
# [*mnt_base_dir*]
|
|
# (optional) The directory where the flat files that store the file system
|
|
# to be loop back mounted are actually mounted at.
|
|
# Defaults to '/srv/node', base directory where disks are mounted to
|
|
#
|
|
# [*byte_size*]
|
|
# (optional) The byte size that dd uses when it creates the file system.
|
|
# Defaults to '1024', block size for the disk. For very large partitions, this should be larger
|
|
#
|
|
# [*seek*]
|
|
# (optional) The size of the file system that will be created.
|
|
# Defaults to 25000.
|
|
#
|
|
# [*fstype*]
|
|
# (optional) The filesystem type.
|
|
# Defaults to 'xfs'.
