`systemctl restart devstack@c*` #重新啟動cinder cinder-volume 過一會就會down狀態,所有虛擬機都無法啟動.
root@ubsv:~# vgs

stack-volumes-lvmdriver-1 1 5 0 wz--n- <24.00g <1.15g #沒有空間了
ubuntu-vg 2 4 0 wz--n- <1.83t <63.54g
那就增加個 vg吧.
修改
vim /etc/cinder/cinder.conf
#修改的
default_volume_type = lvmdriver-2
enabled_backends = lvmdriver-1,lvmdriver-2
#原有的
[lvmdriver-1]
image_volume_cache_enabled = True
volume_clear = zero
lvm_type = auto
target_helper = tgtadm
volume_group = stack-volumes-lvmdriver-1
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_backend_name = lvmdriver-1
#新增
[lvmdriver-2]
volume_group = ubuntu-vg
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_backend_name = lvmdriver-2
重新啟動cinder服務
systemctl restart devstack@c*
重新查看下狀態,發現已經有了.

在dashboard中 管理員登錄, 管理員-卷類型-創建卷類型 {隨便取個名字吧},然后找到新創建的卷類型點擊下三角箭頭->查看擴展規格 創建一個鍵值對 volume_backend_name lvmdriver-2 剛才我們創建的.
之后可以遷移卷到我們新的卷類型. 以后默認新建卷都存儲在我們新建的lvmdriver-2#lvmdriver-2 中,至此 目前解決了這個問題.
