From 26525618863afcc4aab8b2a83451d37c6f513460 Mon Sep 17 00:00:00 2001 From: Lars Ellenberg Date: Fri, 5 Nov 2010 09:56:33 +0100 Subject: [PATCH] drbd: only reset online-verify start sector if verify completed For network hickups during online-verify, on the next verify triggered, we by default want to resume where it left off. After any replication link interruption, there will be a (possibly empty) resync. Do not reset online-verify start sector if some resync completed, that would defeats the purpose. Only reset the start sector once a verify run is completed.
