# follow the instructions for creating a loopback device
|
|
# for storage from: https://docs.openstack.org/swift/latest/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'.
|
|
