some updates. I Have replaced rtl with e1000 but no luck in short: - start drbd on node A, become master - mount device, start a service (for example mysql with db on the drbd mounted partition or squid with logs on mounted partition) - start drbd on node B, it becomes secondary stop mysql, all is ok start mysql, all is ok reboot node b (secondary) when it comes up again, I start drbd on it and it becomes again secondary at this point...: stop mysql on node A (primary) and... soft lockup. it hangs until I stop drbd on the node b (secondary). as soon as I stop it, node A works again and mysql (or any other service hanging) stop immediately. I'm stuck now... Any hints please? Thanks in advance I'm using protocol C, one resource, external metadata. Partition is 360GB First time I have a similar issue.. > _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
