From b1f986c3492faa2d5386fc7baabbd6d8e370554a Mon Sep 17 00:00:00 2001 From: Vladislav Belogrudov Date: Wed, 17 Aug 2016 18:07:10 +0300 Subject: Cinder cannot use external non-LVM iSCSI storage Currently Cinder enables iscsid service only when LVM is choosen as backend. This fix will allow to specify external iSCSI storage via configuration add-on and to run iscsid independently of LVM settings.
