ceph rbd feature 配置disable掉一些exclusive-lock等参数，降低重启后一些故障问题
命令如下：
rbd feature disable exclusive-lock object-map fast-diff deep-flatten --image volume-b71f4ab1-44c7-482c-8361-190cea8a6748-p vms
挂载磁盘进行修复，无法解决，后来测试关闭卷高级feature后虚拟机可以正常启动，关闭卷的高级feature命令如下：
rbd feature disable exclusive-lock object-map fast-diff deep-flatten --image volume-b71f4ab1-44c7-482c-8361-190cea8a6748 -p volumes
# 开闭后效果
# rbd info volume-b71f4ab1-44c7-482c-8361-190cea8a6748 -p volumes-hdd
rbd image 'volume-b71f4ab1-44c7-482c-8361-190cea8a6748':

这样会解决很多问题。

kvm后端存储是ceph的也存在这个问题。按照同样的方法执行下即可。记得destroy再start就好了。
