rename 接口实现方案（已实现，选用方案二）© XXX Page 2 of 15 1. 2. 3. 4. 1. 2. 1. 3. 1. 2. 背景 方案调研 Chubaofs Juicefs 方案实现 方案一：chubaofs 方案二：事务方案 方案三：利用 KV 自带的分布式事务 Q&A 1. 是否需要实现跨文件系统的 rename 2：rename A→C (A 存在，而 C 存在) 4. 当 2 个操作的 dentry 属于同一个 copyset 有什么不一样？ 背景 当前 curvefs 并没有实现 rename 接口，本文档是对 rename 接口实现的调研及方案设计。 rename 操作，主要操作的是 dentry，如 rename /dir1/file1 /dir2/file2，主要有 2 个步骤：(1) 删除 file1 等同 file1 的 inode id）。 关于 rename 接口的实现，主要调研了 chubaofs 和 juicefs，而 rename 的实现难点主要在于其原子性的保证。 方案调研 Chubaofs chubaofs 中的 rename 实现不是原子性的，它是通 用创建源文件的硬连接，然后删除源文件的方式来实现的，主要有以下 4 步 ： 将源文件的 nlink 加一 创建目标文件的
