Oracle 18c opatch util cleanup 不起作用

系统：

[oracle@hostname:/opt/oraclegrid/18]$ uname -a
SunOS hostname 5.11 11.4.24.75.2 sun4v sparc sun4v

数据库：

Oracle 18c 18.10 (April 2020 patch), RacOneNode setup

补丁

OPatch Version: 12.2.0.1.21

我发现，GRID/DB home 中的 .patch_storage 文件夹在文件系统上占用了很多空间。我尝试使用 opatch util cleanup 实用程序（此实用程序应该清理此文件夹）但没有任何反应。这是输出：

[oracle@hostname:/opt/oraclegrid/18]$ du -hs .patch_storage/
 4.1G   .patch_storage
[oracle@hostname:/opt/oraclegrid/18]$ opatch util cleanup

Invoking utility "cleanup"
OPatch will clean up 'restore.sh,make.txt' files and 'scratch,backup' directories.
You will be still able to rollback patches after this cleanup.
Do you want to proceed? [y|n]

OPatch succeeded.

这是一个错误吗？还是我做错了什么？最新版本的 opatch 是否不再支持此命令？感谢你们
