我有centos 7 64位
我收到这个错误：

我检查并发现我的 pool00_tmeta 分区是只读访问权限

我尝试使用此命令将其变为 rw 但它不起作用：
lvchange -prw -ay centos/pool00
Command on LV centos/pool00 uses options invalid with LV type thinpool.
Command not permitted on LV centos/pool00.
这是我的分区：

vmware中很难
当我重新启动操作系统时，在启动时需要发送 CTRL+D 来启动
如何将 this 从只读挂载为读写
谁能帮我？
