在 WSL 上为 Ceph 创建新的 /dev/sd{b,c,d}

在 WSL 上为 Ceph 创建新的 /dev/sd{b,c,d}

我正在尝试在我的 Ubuntu WSL 发行版上运行 (micro)K8s 上的 Ceph。

由于没有可用的支持设备，因此未创建 OSD pod（请参阅下面的日志）。

Ceph 配置为使用所有设备您可以在上面的日志中看到它正在搜索一个。

Ceph 理想情况下需要一个我在 Windows 主机上创建的未格式化的分区，但我不确定如何将其安装/dev/sd{c}到 WSL 本身内，或者尝试创建一个新的分区？

我不知道该怎么做，也不知道这是否是正确的方法。

提前致谢。

答案1

除了现有的 NTFS (drvfs/9P) 磁盘外，WSL 尚不支持安装其他物理或虚拟磁盘。此功能即将推出，但仍处于预览此时。

即便如此，听起来文件系统需要已经安装在驱动器上才能挂载它。但事实并非如此声音就像我们将能够添加原始的、未格式化的分区，但也许会有一个解决方法。

答案2

我花了几天的时间来理清这个问题，但为了使它正常工作，您需要：

  1. 获取 Windows 10 的开发者预览版，这样你就可以--mount选择 WSL
  2. 在 Windows 主机上创建 VHDX。您可以通过磁盘管理器执行此操作并在操作菜单下创建动态 VHDX。
  3. 按照 @NotTheDr01ds 的建议安装该 VHDX，然后就会创建 1/dev/sd{x}1。在我的用例中，这允许 Ceph 使用该磁盘创建 OSD。
