There are lots of possible reasons. Discard might not be enabled on both nodes, there should be a message about discard being available or unavailable in the logs. IIRC, if it can't discard, it will zero-out. The network may have too high latency or too low bandwidth. Without a great amount of detailed information all one can do about performance-related issues is to guess. Generally, both nodes should be running the same and most recent version of DRBD 9, because all those features have been added quite recently, and lots of enhancements and fixes are still applied to the code. -- Robert Altnoeder +43 1 817 82 92 0 [email protected] LINBIT | Keeping The Digital World Running DRBD - Corosync - Pacemaker f / t / in / g+ DRBD® and LINBIT® are registered trademarks of LINBIT, Austria. _______________________________________________ drbd-user mailing list [email protected] http://lists.linbit.com/mailman/listinfo/drbd-user
