>
> The problem is that when performing an HA failover from server A to
> server B, a DRBD resource is sometimes not shut down properly on server A.
> Several attempts are made to stop the DRBD resource, but finally it gives up
> and the server is rebooted. The failover to server B works properly; B
> becomes the Active server. After the reboot, server A comes up properly as
> the Standby server.
>
> So everything ends up in a good state (B is Active, A is Standby as
> expected). The issue is that server A is unexpectedly rebooted during the
> failover. We are vulnerable for the time period that server A is rebooting
> (a few minutes) in the sense that there is no Standby server to failover to.

> The problem is intermittent. Most HA failovers work as expected (server A
> does not reboot).

> When the problem does occur, the following lines are logged in the logs

> drbd0: State change failed: Device is held open by someone
