Fixed In Version:	openstack-packstack-7.0.0-0.11.dev1692.g1b5e83b.el7ost	Doc Type:	Bug Fix
Doc Text:	Previously, Packstack edited the /etc/lvm/lvm.conf file to set specific parameters for snapshot autoextend. However, the regexp used only allowed blank spaces instead of the tabs as currently used in the file. As a result, some lines were added at the end of the file, breaking its format. With this update, the regexp is updated in Packstack to set the parameters properly. As a result, there are no error messages when running LVM commands.	Story Points:	---

Looks like I had these 2 parameters set 2x.  deleted the last 2 at the end of the file and believe all is good.
