cinder-volume服务没起来 已经重启服务也还是down状态，启动日志看看有没有报错

[[email protected] ~]# systemctl restart openstack-cinder-volume.service[[email protected] log]# tail -f messagesApr 17 18:17:33 controller cinder-volume: 2019-04-17 18:17:33.112 3085 ERROR cinder.volume.manager Stderr: u‘  Volume group "cinder-volumes" not found  Cannot process volume group cinder-volumes‘Apr 17 18:17:33 controller cinder-volume: 2019-04-17 18:17:33.112 3085 ERROR cinder.volume.managerApr 17 18:17:33 controllern cinder-volume: 2019-04-17 18:17:33.337 3085 INFO cinder.volume.manager [req-1c834e71-3c13-474e-8f96-8391d7d471f7 - - - - -] Initializing RPC dependent components of volume driver LVMVolumeDriver (3.0.0)Apr 17 18:17:33 controller cinder-volume: 2019-04-17 18:17:33.339 3085 WARNING cinder.volume.drivers.lvm [req-1c834e71-3c13-474e-8f96-8391d7d471f7 - - - - -] Unable to update stats on non-initialized Volume Group: cinder-volumesApr 17 18:17:33 controller cinder-volume: 2019-04-17 18:17:33.355 3085 INFO cinder.volume.manager [req-1c834e71-3c13-474e-8f96-8391d7d471f7 - - - - -] Driver post RPC initialization completed successfully.

大致报错信息是指找不到cinder-volumes这个卷组

[[email protected]~]# vgs 没有卷组[[email protected] ~]# pvcreate /dev/vda7  创建一个物理卷[[email protected] ~]# vgcreate cinder-volumes /dev/vda7  创建卷组[[email protected] ~]# vgs  VG            #PV #LV #SN Attr   VSize VFree  cinder-volume   1   0   0 wz--n- 4.75g 4.75g 现在有了    #再去看一下配置文件 确保万一    [lvm]    volume_group = cinder-volumes    #重启服务    [[email protected] ~]# systemctl restart openstack-cinder-volume.service target.service    [[email protected] ~]# cinder service-list+------------------+--------------+------+---------+-------+----------------------------+-----------------+|      Binary      |     Host     | Zone |  Status | State |         Updated_at         | Disabled Reason |+------------------+--------------+------+---------+-------+----------------------------+-----------------+| cinder-scheduler |   controller   | nova | enabled |   up  | 2019-04-17T18:36:09.000000 |        -        ||  cinder-volume   | [email protected] | nova | enabled |   up  | 2019-04-17T18:36:04.000000 |        -        |+------------------+--------------+------+---------+-------+----------------------------+-----------------+

这样就解决了。
