## 更新镜像的大小

`$ tunasynctl set-size -w <worker_id> <mirror_name> <size>`

||||
```shell

||||
$ tunasynctl set-size -w <worker_id> <mirror_name> <size>
|
||||
```
|
||||
|
||||
其中,末尾的 <size> 参数,由操作者设定,或由某定时脚本生成
|
||||
|
||||
由于 `du -s` 比较耗时,故镜像大小可直接由rsync的日志文件读出
|
||||
|
||||
|
||||
## Btrfs 文件系统快照
|
||||
|
||||
如果镜像文件存放在以 Btrfs 为文件系统的分区中,可启用由 Btrfs 提供的快照 (Snapshot) 功能。对于每一个镜像,tunasync 在每次成功同步后更新其快照。
|
||||
|
||||
在 `worker.conf` 中添加如下配置,即可启用 Btrfs 快照功能:
|
||||
|
||||
```toml
|
||||
[btrfs_snapshot]
|
||||
enable = true
|
||||
snapshot_path = "/path/to/snapshot/directory"
|
||||
```
|
||||
|
||||
其中 `snapshot_path` 为快照所在目录。如将其作为发布版本,则镜像同步过程对于镜像站用户而言具有原子性。如此可避免用户接收到仍处于“中间态”的(未完成同步的)文件。
|
||||
|
||||
也可以在 `[[mirrors]]` 中为特定镜像单独指定快照路径,如:
|
||||
|
||||
```toml
|
||||
[[mirrors]]
|
||||
name = "elvish"
|
||||
provider = "rsync"
|
||||
upstream = "rsync://rsync.elvish.io/elvish/"
|
||||
interval = 1440
|
||||
snapshot_path = "/data/publish/elvish"
|
||||
```
|
||||
|
||||
**提示:**
|
||||
|
||||
若运行 tunasync 的用户无 root 权限,请确保该用户对镜像同步目录和快照目录均具有写和执行权限,并使用 [`user_subvol_rm_allowed` 选项](https://btrfs.wiki.kernel.org/index.php/Manpage/btrfs(5)#MOUNT_OPTIONS)挂载相应的 Btrfs 分区。
