2. 详细叙述
root@iStoreOS:/etc# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS
sda 8:0 0 2.4G 0 disk

└─sda3 8:3 0 2G 0 part /overlay/upper/opt/docker
/overlay
(1) 具体问题
我在PVE上装了虚拟机istoreos，开机提示信息：overlayfs: lowerdir is in-use as upperdir/workdir of another mount ,accessing files from both mounts will result in undefined behavior
这个告警不影响正常使用。但是我对这个现象不太理解，感觉可能是挂载有问题。所以想请教一下/dev/sda3为什么会挂载两次呢？
└─sda3 8:3 0 2G 0 part /overlay/upper/opt/docker
/overlay
查看web页面-系统-挂载点，实际上只有 /overlay，那是不是说明/overlay/upper/opt/docker这个挂载动作没什么作用呢？
在哪里能删掉，是docker启动脚本造成的吗
