<div dir="ltr"><span style="font-family:arial,sans-serif;font-size:13px">I use devstack (Grizzly/stable). I have been trying to use a different volume driver by muncommenting and modifying the below line in cinder.conf under etc/cinder</span><div style="font-family:arial,sans-serif;font-size:13px">

But when VolumeManager is loaded I see it still refers to the default LVMISCSIDriver. Is there any other change to load cinder.conf? </div><div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">
