Currently facter only support to fetch the partition's uuid, If users want to mount device by uuid, then partitions should be made in the disks. This patch aims to add new param $ext_args in swift::storage::disk to enable passing making partitions arguments in parted command. Change-Id: I26dcfe73d2791a9033b555323847ddd211f02ceb

# This Puppet resource is based on the following
|
|
# instructions for creating a disk device:
|
|
# http://docs.openstack.org/developer/swift/development_saio.html
|
|
#
|
|
# ==Add a raw disk to a swift storage node==
|
|
#
|
|
# It will do two steps to create a disk device:
|
|
# - creates a disk table, use the whole disk instead
|
|
# to make the partition (e.g. use sdb as a whole)
|
|
# - formats the partition to an xfs device and
|
|
# mounts it as a block device at /srv/node/$name
|
|
#
|
|
# ATTENTION: You should not use the disk that your Operating System
|
|
# is installed on (typically /dev/sda/).
|
|
#
|
|
# === 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
|
|
#
|
|
# [*ext_args*]
|
|
# (optional) The external command that will be used in parted command.
|
|
# Default to ''. For making partitions, it would be 'mkpart primary 0% 100%'.
|
|
#
|
|
# =Example=
|
|
#
|
|
# Simply add one disk sdb:
|
|
#
|
|
# swift::storage::disk { "sdb":}
|
|
#
|
|
# Add more than one disks and overwrite byte_size:
|
|
#
|
|
# swift::storage::disk {['sdb','sdc','sdd']:
|
|
# byte_size => '2048',
|
|
# }
|
|
#
|
|
# TODO(yuxcer): maybe we can remove param $base_dir
|
|
