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"
