 .IP refresh-drbd-resource
 This requires \fB\-\-resource <new name>\fR, and will call 'drbdadm adjust <resource>' as a background task and then return immediately. This is required when adding a new volume to an existing resource as 'drbdadm adjust <res>' will hold until it is called on all active DRBD nodes. This blocks the caller after the first remote host call.

-.IP safe-stop
-This implies \fB\-\-no\-db\fR, and will call 'anvil-safe-stop' as a background task. This is designed to ensure that a nodes leave the subcluster, and for DR host to shut down servers. This is done when the host is not yet updated, and the Striker dashboards have been upgraded with a new database schema.

-This implies \fB\-\-no\-db\fR, and will call 'anvil-update-system' as a background task. This allows remote machines to call for the update without risk of timing out the network connection.

-Note: \fB\-\-no\-reboot\fR, \fB\-\-clear\-cache\fR, and \fB\-\-reboot\fR are all available here and passed to 'anvil-update-system'. See it's manpage for usage information.
