Xavpaice Swift Storage

Learn about configurations >

• account-max-connections | int

  Default: 2

  Number of connections allowed to the account rsync stanza.

• account-server-port | int

  Default: 6002

  Listening port of the swift-account-server.

• action-managed-upgrade | boolean

  If True enables openstack upgrades for this charm via juju actions. You will still need to set openstack-origin to the new repository but instead of an upgrade running automatically across all units, it will wait for you to execute the openstack-upgrade action for this charm on each unit. If False it will revert to existing behavior of upgrading all units on config change.

• allow-ufw-ip6-softfail | boolean

  When this option is set to True the charm will disable the IPv6 support in ufw in case ip6tables couldn't be activated, situations where this could happen is in a LXC container running on top of a host that doesn't have loaded the ip6_tables. If this option is False (the default) and ip6_tables module couldn't be loaded, the charm will fail to install.

• block-device | string

  Default: sdb

  Device to be used to back Swift storage. May be any valid block device or a path and size to a local file (/path/to/file.img|$sizeG), which will be created and used as a loopback device (for testing only). Multiple devices may be specified as a space-separated list of devices. If set to "guess", the charm will attempt to format and mount all extra block devices (this is currently experimental and potentially dangerous).

• container-max-connections | int

  Default: 2

  Number of connections allowed to the container rsync stanza.

• container-server-port | int

  Default: 6001

  Listening port of the swift-container-server.

• enable-firewall | boolean

  Default: True

  By default the swift-storage charm will use the UFW firewall to protect storage daemons. This option allows the administrator to disable this feature.

• encrypt | boolean

  Encrypt block devices used by swift using dm-crypt, making use of vault for encryption key management; requires a relation to vault.

• ephemeral-unmount | string

  Cloud instances provide ephermeral storage which is normally mounted on /mnt. . Setting this option to the path of the ephemeral mountpoint will force an unmount of the corresponding device so that it can be used as a swift storage device. This is useful for testing purposes (cloud deployment is not a typical use case).

• harden | string

  Apply system hardening. Supports a space-delimited list of modules to run. Supported modules currently include os, ssh, apache and mysql.

• nagios-check-params | string

  Default: -m -r 60 180 10 20

  String appended to nagios check

• nagios_context | string

  Default: juju

  Used by the nrpe-external-master subordinate charm. A string that will be prepended to instance name to set the host name in nagios. So for instance the hostname would be something like: juju-myservice-0 If you're running multiple environments with the same services in them this allows you to differentiate between them.

• nagios_servicegroups | string

  A comma-separated list of nagios servicegroups. If left empty, the nagios_context will be used as the servicegroup

• object-max-connections | int

  Default: 2

  Number of connections allowed to the object rsync stanza.

• object-replicator-concurrency | int

  Default: 1

  Number of replication workers to spawn.

• object-rsync-timeout | int

  Default: 900

  Max duration of a partition rsync (in seconds).

• object-server-port | int

  Default: 6000

  Listening port of the swift-object-server.

• object-server-threads-per-disk | int

  Default: 4

  Size of the per-disk thread pool used for performing disk I/O. 0 means to not use a per-disk thread pool. It is recommended to keep this value small, as large values can result in high read latencies due to large queue depths. A good starting point is 4 threads per disk.

• openstack-origin | string

  Default: distro

  Repository from which to install. May be one of the following: distro (default), ppa:somecustom/ppa, a deb url sources entry, or a supported Cloud Archive release pocket. Supported Cloud Archive sources include: cloud:<series>-<openstack-release> cloud:<series>-<openstack-release>/updates cloud:<series>-<openstack-release>/staging cloud:<series>-<openstack-release>/proposed For series=Precise we support cloud archives for openstack-release: * icehouse For series=Trusty we support cloud archives for openstack-release: * juno * kilo * ... NOTE: updating this setting to a source that is known to provide a later version of OpenStack will trigger a software upgrade.

• overwrite | string

  Default: false

  If true, charm will attempt to unmount and overwrite existing and in-use block-devices (WARNING).

• prefer-ipv6 | boolean

  If True enables IPv6 support. The charm will expect network interfaces to be configured with an IPv6 address. If set to False (default) IPv4 is expected. NOTE: these charms do not currently support IPv6 privacy extension. In order for this charm to function correctly, the privacy extension must be disabled and a non-temporary address must be configured/available on your network interface.

• statsd-host | string

  Enable statsd metrics to be sent to the specified host. If this value is empty, statsd logging will be disabled.

• statsd-port | int

  Default: 3125

  Destination port on the provided statsd host to send samples to. Only takes effect if statsd-host is set.

• statsd-sample-rate | float

  Default: 1.0

  Sample rate determines what percentage of the metric points a client should send to the server. Only takes effect if statsd-host is set.

• sysctl | string

  YAML formatted associative array of sysctl values, e.g.: '{ kernel.pid_max : 4194303 }'

• worker-multiplier | float

  Default: 1.0

  The CPU multiplier to use when configuring worker processes for the account, container and object server processes.

• zone | int

  Default: 1

  Swift storage zone to request membership. Relevant only when the swift-proxy charm has been configured for manual zone assignment (the default). This should be changed for every service unit.
