오픈스택 클라우드 서버 구축(Stein)(11)-Block Storage(Cinder) 설정(LVM)

#Storage Node 설정

1) Create a volume group for Cinder on Storage Node.

[root@storage ~]# pvcreate /dev/sdb1
Physical volume "/dev/sdb1" successfully created
[root@storage ~]# vgcreate -s 32M vg_volume01 /dev/sdb1
Volume group "vg_volume01" successfully created

2) Configure Cinder Volume on Storage Node.

[root@storage ~]# vi /etc/cinder/cinder.conf
# add follows into [DEFAULT] section
enabled_backends = lvm

# add follows to the end
[lvm]
target_helper = lioadm
target_protocol = iscsi
# IP address of Storage Node
target_ip_address = 10.0.0.50
# volume group name just created
volume_group = vg_volume01
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volumes_dir = $state_path/volumes

[root@storage ~]# systemctl restart openstack-cinder-volume

3) 방화벽 포트 설정

[root@storage ~]# firewall-cmd --add-service=iscsi-target --permanent
success
[root@storage ~]# firewall-cmd --reload
success

# Compute Node 설정

1) Configure Nova on Compute Node.

[root@computer ~]# vi /etc/nova/nova.conf
# add to the end
[cinder]
os_region_name = RegionOne

[root@computer ~]# systemctl restart openstack-nova-compute

#Controller Node 설정

1) 볼륨 생성

[root@controller ~(keystone)]# echo "export OS_VOLUME_API_VERSION=3" >> ~/keystonerc
[root@controller ~(keystone)]# source ~/keystonerc
[root@controller ~(keystone)]# openstack volume create --size 10 disk01
