[DRBD-user] DRBD performance

I set up 2-node NFS cluster on drbd 8.4 across two sites connected with 10GB link. I run MQ benchmark with result of 100 units which is poor. When I disable drbd synchronizations I get 200 units which is good. That's twice faster. Is it normal for drbd to slow down that much ? Thank you ___

http://docs.linbit.com/docs/users-guide-9.0/p-work/ 5.2.2. Status information in /proc/drbd '/proc/drbd' is deprecated. While it won’t be removed in the 8.4 series, we recommend to switch to other means, like Section 5.2.3, “Status information via drbdadm”; or, for monitoring even more convenient

Hi, On a 2 node cluster when I do a failover test I get messages in logs on the healthy node: Jul 16 22:55:39 centos2 kernel: drbd storage centos1: fence-peer helper broken, returned 1 Jul 16 22:55:39 centos2 kernel: drbd storage: State change failed: Refusing to be Primary while peer is not outda
