Are Regular VACUUM ANALYZE Still Recommended Under 9.1?

Note

This module is part of ansible-base and included in all Ansible installations. In most cases, you can use the short module name systemd even without specifying the collections: keyword. Despite that, we recommend you use the FQCN for easy linking to the module documentation and to avoid conflicting with other collections that may have the same module name.

Synopsis

• Controls systemd services on remote hosts.

Requirements

The below requirements are needed on the host that executes this module.

• A system managed by systemd.

Parameters

Parameter	Choices/Defaults	Comments
daemon_reexec boolean added in 2.8 of ansible.builtin	Choices: no ← yes	Run daemon_reexec command before doing any other operations, the systemd manager will serialize the manager state. aliases: daemon-reexec
daemon_reload boolean	Choices: no ← yes	Run daemon-reload before doing any other operations, to make sure systemd has read any changes. When set to yes, runs daemon-reload even if the module does not start or stop anything. aliases: daemon-reload
enabled boolean	Choices: no yes	Whether the service should start on boot. At least one of state and enabled are required.
force boolean added in 2.6 of ansible.builtin	Choices: no yes	Whether to override existing symlinks.
masked boolean	Choices: no yes	Whether the unit should be masked or not, a masked unit is impossible to start.
name string		Name of the service. This parameter takes the name of exactly one service to work with. When using in a chroot environment you always need to specify the full name i.e. (crond.service). aliases: service, unit
no_block boolean added in 2.3 of ansible.builtin	Choices: no ← yes	Do not synchronously wait for the requested operation to finish. Enqueued job will continue without Ansible blocking on its completion.
scope string added in 2.7 of ansible.builtin	Choices: system ← user global	Run systemctl within a given service manager scope, either as the default system scope system, the current user's scope user, or the scope of all users global. For systemd to work with 'user', the executing user must have its own instance of dbus started and accessible (systemd requirement). The user dbus process is normally started during normal login, but not during the run of Ansible tasks. Otherwise you will probably get a 'Failed to connect to bus: no such file or directory' error. The user must have access, normally given via setting the ``XDG_RUNTIME_DIR`` variable, see example below.
state string	Choices: reloaded restarted started stopped	started/stopped are idempotent actions that will not run commands unless necessary. restarted will always bounce the service. reloaded will always reload.

Notes

Note

• Since 2.4, one of the following options is required ‘state’, ‘enabled’, ‘masked’, ‘daemon_reload’, (‘daemon_reexec’ since 2.8), and all except ‘daemon_reload’ (and ‘daemon_reexec’ since 2.8) also require ‘name’.
• Before 2.4 you always required ‘name’.
• Globs are not supported in name, i.e postgres*.service.
• Supports check_mode.
