However, as far as I remember, the resources use auto-promotion, so while the resource is in allow-two-primaries mode, it is normally only in the Primary role on one node, unless a live migration is in progress where both nodes open the device simultaneously. Upon closing the device, it switches back to the Secondary role when auto-promotion is used. br, -- Robert Altnoeder +43 1 817 82 92 0 robert.altnoeder at linbit.com LINBIT | Keeping The Digital World Running DRBD - Corosync - Pacemaker f / t / in / g+ DRBD® and LINBIT® are registered trademarks of LINBIT, Austria.
