Re: [DRBD-user] oracle stop timeout while drbd resync
The environment has been recovered. I modified the pacemaker stop fail action to "echo c >/proc/sysrq-trigger" so that the system will be reboot and generate vmcore when resource stop fail. I am sure that the reason is oracle stop action is stalled during drbd resync. All the device used the same replication link.
