From 369bea63711ae0595f6ef8c3c02bbf8a17ec608a Mon Sep 17 00:00:00 2001 From: Philipp Reisner Date: Wed, 6 Jul 2011 23:04:44 +0200 Subject: [PATCH] drbd: Fixed removal of volumes/devices from connected resources When removing a volume/device we need to switch the connection status of the peer back into WFReportParams. Before this fix it was left in Connected state. That means that the peer device continued to inform us about state changes, etc... But we deleted that minor -> protocol error.
