I'm running DRBD 8.3.8 (GIT-hash: d78846e52224fd00562f7c225bcc25b2d422321d build by mockbuild at builder10.centos.org, 2010-06-04 08:04:27) and have recently turned on data-integrity-alg (to sha1) for my resources. Since then, I'm consistently (many times hourly) getting integrity failures for one of them. The peer says "Digest integrity check FAILED.", then hangs up and reconnects. Everything appears to keep going just fine, but surely this shouldn't be happening in the first place? This seems pretty weird to me, because... 1) all my resources are going over the same cable, and this particular resource has an issue way more than any others. 2) this particular resource is changing the least out of all my others. 3) this particular resource passed an online verify without any complaints. I'd be happy to blame a NIC or the cable, except that all the other DRBD traffic is using the same hardware. Is there anything I can provide that might explain what's going on? If it matters this is on a dom0 xen kernel.
