有没有办法将不同的磁盘挂载为一个目录？假设我有一些带有 ext4 分区的磁盘：

/dev/sda1 1Tb  mounted as /store1
/dev/sda2 2Tb  mounted as /store2
/dev/sdb1 2Tb  mounted as /store3
/dev/sdb2 2Tb  mounted as /store4

我想拥有/storeall7Tb 空间，将它们合并为一个逻辑目录，这样我就可以用一个rsync命令填充它。

在 Linux 上可以吗？我应该使用哪个文件系统？

在 Scientific linux 6.0（RH like linux）上我不小心删除了 python，所以 yum 也删除了。µ

如何用rpm安装yum？

我尝试安装 python，但它以某种方式循环依赖：

rpm -Uvh http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/python-libs-2.6.5-3.el6.x86_64.rpm
    Retrieving http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/python-libs-2.6.5-3.el6.x86_64.rpm
    error: Failed dependencies:
            python = 2.6.5-3.el6 is needed by python-libs-2.6.5-3.el6.x86_64

然后：

 rpm -Uvh http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/python
-2.6.5-3.el6.x86_64.rpm
Retrieving http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/python-2.6.5-3.el6.x86_64.rpm
error: Failed dependencies:
