二 配置存储节点

安装软件包

yum install lvm2 device-mapper-persistent-data

#启动
systemctl enable lvm2-lvmetad.service
systemctl start lvm2-lvmetad.service

创建LVM物理卷

#创建 LVM 物理卷/dev/sdb
pvcreate /dev/sdb

报错ERROR：No device found for /dev/sdb.
解决：
#对/dev/vdb进行使用
fdisk -l
p
#一路默认

#格式化
mkfs.ext3 /dev/vdb1

pvcreate /dev/vdb1

创建 LVM 卷组cinder-volumes

vgcreate cinder-volumes /dev/vdb1

添加过滤

#/etc/lvm/lvm.conf 
devices {
...
filter = [ "a/sdb/", "r/.*/"]

安装软件包

yum install openstack-cinder targetcli python-keystone

报错ERROR：Error: Unable to find a match: python-keystone
解决：
yum install openstack-cinder targetcli python3-keystone

配置cinder

#/etc/cinder/cinder.conf
[database]
# ...
connection = mysql+pymysql://cinder:CINDER_DBPASS@controller/cinder
[DEFAULT]
# ...
transport_url = rabbit://openstack:RABBIT_PASS@controller
[DEFAULT]
# ...
auth_strategy = keystone

[keystone_authtoken]
# ...
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = CINDER_PASS
[DEFAULT]
# ...
my_ip = MANAGEMENT_INTERFACE_IP_ADDRESS
[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
target_protocol = iscsi
target_helper = lioadm
[DEFAULT]
# ...
enabled_backends = lvm
[DEFAULT]
# ...
glance_api_servers = http://controller:9292
[oslo_concurrency]
# ...
lock_path = /var/lib/cinder/tmp

完成安装

systemctl enable openstack-cinder-volume.service target.service
systemctl start openstack-cinder-volume.service target.service
