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

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

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.

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)

This resource agent supports the following actions (operations):

start

Starts the resource. Suggested minimum timeout: 20s.

stop

Stops the resource. Suggested minimum timeout: 20s.

monitor

Performs a detailed status check. Suggested minimum timeout: 20s. Suggested interval: 60s.

validate-all

Performs a validation of the resource configuration. Suggested minimum timeout: 20s.

meta-data

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

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

primitive p_drbd-attr ocf:linbit:drbd-attr \


  op monitor timeout="20s" interval="60s" depth="0"

The following is an example configuration for a drbd-attr resource using pcs(8)

pcs resource create p_drbd-attr ocf:linbit:drbd-attr \


  op monitor timeout="20s" interval="60s" depth="0"
