Question

我正在尝试访问以前由docker使用的逻辑卷。这是各种命令的结果：

lsblk

    └─docker-docker--pool     253:2    0  79G  0 lvm

但是当我尝试挂载卷docker-docker--pool_tdata时，出现以下错误：

mount  /dev/mapper/docker-docker--pool_tdata /mnt/test
mount: /dev/mapper/docker-docker--pool_tdata is already mounted or /mnt/test busy

我还尝试过重启计算机，卸载docker，并使用lsof

查看该卷上是否打开了文件。

关于如何安装该卷，您有任何线索吗？谢谢
