Hi,

If SELinux is enabled on your machine, could you check if there are any AVCs (grep avc /var/log/audit/audit.log) related to iscsiadm? I have seen that in some deployments, and found out the instructions in [1] to be helpful.

Regards,
Javier

And its status is error.].

seems my cinder volume no free space. I install VM with 80G storage but cinder volume no space.
I tried extend cinder volume as follows

lvm vgextend "cinder-volumes" /dev/loop3
  Physical volume "/dev/loop3" successfully created.
  Volume group "cinder-volumes" successfully extended

When try to create new instance I keep getting the same volume error... Please help and advise what should I do...Please help...why 80G still not enough for cinder volume. 

Appreciate help. Thank you
