devstack cinder-volume服務狀態為down

鍵值對 driver help devstack vim all clear mod ubuntu

cinder-manage service list
查看到有一個 xxx狀態

`systemctl restart [email protected]*` #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.

  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 [email protected]*

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},然後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.

之後可以遷移卷到我們新的卷類型. 以後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.
