Hi guys,

Im trying to attach a volume to an instance and im not getting the volume when fdisk -l

Dont know how to follow this step at openstack

In the [lvm] section, configure the LVM back end with the LVM driver, cinder-volumes volume group, iSCSI protocol, and appropriate iSCSI service:

[lvm] ... volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver volume_group = cinder-volumes iscsi_protocol = iscsi iscsi_helper = lioadm

I dont find the [lvm] section and no [lvm] section is in the file.

Here is the cinder.conf file on the storage node => filedropper.com/cinder_1

Here's the log which displays the error.
