Defined Type: swift::storage::ext4

Defined in:
manifests/storage/ext4.pp

Overview

follow the instructions for creating a loopback device for storage from: docs.openstack.org/swift/latest/development_saio.html

this define needs to be sent a refresh signal to do anything

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) 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 It is recommend 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.

Parameters:

  • device (Any)
  • byte_size (Any) (defaults to: '1024')
  • mnt_base_dir (Any) (defaults to: '/srv/node')
  • loopback (Any) (defaults to: false)
