上面可以看到垃圾回收（GC）任务被触发并开始执行，但最终因为内部服务错误（HTTP 500错误）而失败。错误指向的是在尝试启动垃圾回收过程时，与registryctl服务的交互中发生了错误。

查看Registryctl服务的日志：

docker logs registryctl

提示“

2024-04-09T15:47:24Z [ERROR] [/registryctl/api/registry.go:49]: Fail to execute GC: exit status 1, command err: failed to garbage collect: failed to mark: filesystem: filesystem: invalid checksum digest format

”错误

这个问题比较坑，是磁盘数据不一致的错误，只能去github搜索答案，果然有人出现和我一样的错误，貌似harbor有bug，解决方案上是删除磁盘上的空链接

rm $(find /path/to/registry -iname link -size 0)

执行上面代码后，重启harbor问题解决，/path/to/registry 是harbor的存储目录，以真实安装环境为准。
