ocf_linbit_drbd-attr7

Import drbd state change events as transient node attributes

Usage

drbd-attr [start | stop | monitor | meta-data | validate-all]

Overview

This listens for DRBD state change events, and sets or deletes transient node attributes based on the "promotion_score" and "may_promote" values as presented by the DRBD events2 interface.

Optionally using a dampening delay, see attrd_updater for details.

To be used as a clone on all DRBD nodes. The idea is to start DRBD outside of pacemaker, use DRBD auto-promote, and add location constraints for the Filesystem or other resource agents which are using DRBD.

Supported parameters

dampening_delay

To be used as dampening delay in attrd_updater.

(optional, integer, default 5)

attr_name_prefix

The attributes will be named "*prefix*-drbd_resource_name". You can chose that prefix here.

(optional, string, default "drbd-promotion-score")

record_event_details

It may be convenient to know which event lead to the current score. This setting toggles the recording of the event. The attributes will be named "*prefix*:event-details-drbd_resource_name".

(optional, boolean, default false)

start
