ocf_heartbeat_symlink (7)

symlink [start | stop | monitor | meta-data | validate-all]

This resource agent that manages a symbolic link (symlink).

It is primarily intended to manage configuration files which should be enabled or disabled based on where the resource is running, such as cron job definitions and the like.

link

Full path of the symbolic link to be managed. This must obviously be in a filesystem that supports symbolic links.

(required, string, no default)

target

Full path to the link target (the file or directory which the symlink points to).

(required, string, no default)

backup_suffix

A suffix to append to any files that the resource agent moves out of the way because they clash with "link".

If this is unset (the default), then the resource agent will simply refuse to create a symlink if it clashes with an existing file.

(optional, string, no default)

This resource agent supports the following actions (operations):

start

Starts the resource. Suggested minimum timeout: 15.

stop

Stops the resource. Suggested minimum timeout: 15.

monitor

Performs a detailed status check. Suggested minimum timeout: 15. Suggested interval: 60.

meta-data

Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5.

validate-all

Performs a validation of the resource configuration. Suggested minimum timeout: 10.

The following is an example configuration for a symlink resource using the crm(8) shell:

primitive p_symlink ocf:heartbeat:symlink \
  params \
    link=string \
    target=string \
  op monitor depth="0" timeout="15" interval="60"
