The scenario where one node sees another node's disk as Outdated, although the other node itself sees it as UpToDate, or vice-versa, is most probably a bug in DRBD9's state handling. It is commonly resolved by disconnecting and reconnecting the node, because the state is negotiated after connecting. In the case where the faulty state is seen on a peer resource, disconnecting only the connection to those nodes where an incorrect peer state is seen will normally suffice. We are aware that there are still cases where the state handling may cause scenarios like the ones mentioned above. Changes are continuously applied to DRBD9's state handling to fix cases where nodes may disagree about the state of DRBD9's objects. > And NO, I did not signed any SLA with your company.

Granted, there is some truth in this, but we have only limited resources, and obviously we have to prioritize problems reported by our customers, because that's what we make a living from - and also what enables the development of DRBD. Most of the progress with DRBD has been made because the product is primarily being developed by a company which is funded by its customers. Others can benefit from this development, because we also provide the results under a Free Open Source Software license, but that does not imply that everyone is entitled to immediate and free-of-charge improvements of the product. Nevertheless, we still try our best to make the product better for everyone as quickly as our development resources allow. 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.
