File 0306-90multipath-add-shutdown-script.patch of Package dracut.15235
From 800cfd66abb60fe9524d321df77717435ed96e35 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke <hare@suse.de> Date: Thu, 25 Aug 2016 09:33:26 +0200 Subject: [PATCH] 90multipath: add shutdown script As the device-mapper module is removing all device-mapper tables during shutdown we need to make sure to disable queuing on the multipath devices; otherwise there might still be I/O pending and the removal will fail.
