# This Puppet resource is based on the following
|
|
# instructions for creating a disk device:
|
|
# https://docs.openstack.org/swift/latest/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%'.
|
|
#
|
|
# [*manage_partition*]
|
|
# (optional) If set to false, skip calling parted which can, in some cases,
|
|
# increase the load on the server. This is to set to false only after the
|
|
# server is fully setup or if the partition was created outside of puppet.
|
|
# Defaults to true.
|
|
#
|
|
# [*manage_filesystem*]
|
|
# (optional) If set to false, skip calling xfs_admin -l to check if a
|
|
# partition needs to be formatted with mkfs.xfs, which can, in some cases,
|
|
# increase the load on the server. This is to set to false only after the
|
|
# server is fully setup, or if the filesystem was created outside of puppet.
|
|
# Defaults to true.
|
|
#
|
|
# =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
|
|
