I have configured an Active/Active cluster with Dual Primary DRBD. All works fine and fast.

But when a node fails, the DRBD status goes to WFConnection and all IO is blocked on the other node. In this scenario I need the survivor to continue using the DRBD partition. It would be great if when the other node comes back, the synchronization begins automatically and both become Primary automatically.

I have search the doc and google, but have not found any of this. Only the ko-count option, but does not seem to make a difference.

Any ideas?

Thanks in advance.
