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.

|
# === Parameters:
|
|
#
|
|
# [*device*]
|
|
# (mandatory) An array of devices (prefixed or not by /dev)
|
|
#
|
|
# [*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) Byte size to use for every inode in the created filesystem.
|
|
# Defaults to '1024'. It is recommened to use 1024 to ensure that the metadata can fit in a single inode.
|
|
#
|
|
# [*loopback*]
|
|
# (optional) Define if the device must be mounted as a loopback or not
|
|
# Defaults to false.
|
|
#
|
|
# Sample usage:
|
|
#
|
|
# swift::storage::xfs {
|
|
# ['sdb', 'sdc', 'sde', 'sdf', 'sdg', 'sdh', 'sdi', 'sdj', 'sdk']:
|
|
# mnt_base_dir => '/srv/node',
|
|
# require => Class['swift'];
|
|
# }
|
|
#
|
|
# Creates /srv/node if dir does not exist, formats sdbX with XFS unless
|
|
# it already has an XFS FS, and mounts de FS in /srv/node/sdX
|
|
#
|
