I am reasonably sure the network is ok - it's a link via a cisco 2960G, and the interfaces are not being shared with anything except heartbeat. Syncer rate is 30M for both sides, and there are no errors on the "show int" stats on the cisco. The interfaces are running at a gigabit. http://www.drbd.org/users-guide/s-integrity-check.html Read the bullet list. Then start troubleshooting your network stack. When you get "Digest integrity check FAILED" errors, you have every reason _not_ to be sure the network is OK. If you're running on borked Intel NICs from three years or so ago, disabling TX or RX checksum offloading, or TSO, on the NICs in question will help. See "man ethtool" for that. Hope this helps.
