NAME

6       ocf_linbit_drbd-attr - import DRBD state change events as transient
7       node attributes
8

SYNOPSIS

10       drbd-attr [start | stop | monitor | meta-data | validate-all]
11

DESCRIPTION

13       This listens for DRBD state change events, and sets or deletes
14       transient node attributes based on the "promotion_score" and
15       "may_promote" values as presented by the DRBD events2 interface.
16
17       Optionally using a dampening delay, see attrd_updater for details.
18
19       To be used as a clone on all DRBD nodes. The idea is to start DRBD
20       outside of pacemaker, use DRBD auto-promote, and add location
21       constraints for the Filesystem or other resource agents which are using
22       DRBD.
