From 8a3c104438be4986a77f332009b695fcac48f620 Mon Sep 17 00:00:00 2001 From: Lars Ellenberg Date: Sun, 5 Dec 2010 14:11:14 +0100 Subject: [PATCH] drbd: fix regression, we need to close drbd epochs during normal operation commit e2041475e6ddb081734d161f6421977323f5a9b9 drbd: Starting with protocol 96 we can allow app-IO while receiving the bitmap Contained a bad chunk that tried to optimize away drbd barriers during bitmap exchange, but accidentally dropped them for normal mode as well. Impact: depending on activity log size and access pattern, activity log extents may not be recycled in time, causeing IO to block indefinetely. Fix: skip drbd barriers only if there is no connection to send them on, or the request being completed has not been on the network at all.
