Docker部署IBM DB2镜像失败：db2strst.lck锁及权限问题求助

执行以下启动命令尝试运行ibmcom/db2镜像：

docker run --name mydb2 --privileged=true -p 50000:50000 -e LICENSE=accept -e DB2INST1_PASSWORD=test -e DBNAME=testdb ibmcom/db2

启动后db2start出现如下警告：

2023-02-09-18.58.37.677287+000 I307847E393           LEVEL: Warning
PID     : 25258                TID : 139812728498048 PROC : db2start

MESSAGE : Released lock on the file:

/database/config/db2inst1/sqllib/ctrl/db2strst.lck

已尝试以下操作但无效：

• 删除上述警告中的锁文件/database/config/db2inst1/sqllib/ctrl/db2strst.lck
• 进入容器执行命令sudo chown db2inst1 /database/config/db2inst1/sqllib/adm/*，但报错：

  chown: cannot dereference '/database/config/db2inst1/sqllib/adm/ITLMready.properties': No such file or directory
  

查看db2diag.log发现两个错误：
