NAME

       ocf_linbit_drbd-attr - import DRBD state change events as transient node attributes

SYNOPSIS

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

DESCRIPTION

       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)

       meta-data
           Retrieves resource agent metadata (internal use only). Suggested minimum timeout: 5s.
