最近在使用华为云SFS时,如果一个目录存储文件数超过100W,执行 “rm -rf path”时,存在删不动的情况,可以使用华为云API接口,执行异步删除。
华为官网:
删除文件系统目录_弹性文件服务 SFS_API参考_SFS Turbo API说明_目录管理_华为云删除文件系统目录在2023年6月1号之后创建的文件系统支持该API操作。 警告:该API为删除文件系统子目录数据的高危操作,删除后无法恢复,使用前请确认下发的文件系统目录是否正确。您可以在API Explorer中调试该接口,支持自动认证鉴权。API Explorer可以自动生成SDK代码示例,并提供SDK代码示例调试功能。DELETE https://support.huaweicloud.com/api-sfs/DeleteFsDir.html
