i have a very simple setup. have controller node and compute storage node. when creating a volume i get this error in the controller

ihcontrol01  cinder-scheduler.log 
2015-06-10 14:13:25.628 1068 ERROR cinder.scheduler.flows.create_volume [req-084ad6ac-7320-414e-b761-c5faa5b554f1 7c0e5f1bd9eb49c386f1f15e1f1c413e 364f13d600ae45e781d01dbc380267e3 - - -] Failed to schedule_create_volume: No valid host was found.

ihcompute cinder-volume.log seems i setup correctly

when i run this i don't see my compute host should i

root@ihcontrol01:~# cinder-manage host list
host                            zone
ihcontrol01                     nova

I followed this documentation docs in openstack

on my compute server : shows i have 80gb free ..

root@ihcompute:/software/keystone# vgs
  VG             #PV #LV #SN Attr   VSize  VFree
  cinder-volumes   1   0   0 wz--n- 80.00g 80.00g

and i can't even create a 4 gb volume

cinder create --display-name myVolume3 4

let me know if i missed something .

many thanks
