普通linux ssd+HDD混合用户的春天-冬天的折腾

SSD大潮不可阻挡，我也跟风买了个32G ssd准备安装fedora19完成自我感觉的提升

但新买的随身本S3-371和其很多本一样，除了sata口接硬盘外，可供使用的仅剩下msata.同样，和很多本一样，该MSATA上接的ssd不能作为启动盘使用--BIOS上没有该盘的显示，自然也无法选择为启动盘。

但在系统启动后，能查看并对该盘操作。于是各种折腾。

F19默认使用LVM方式保存/home，我无法用flashcache对其做cache，也无法对系统数据最多的/做cache。

发现目前而言，IRST对linux没有足够的支持，使用安装方式过于繁复，我没有办法在不破坏系统的情况下使用SSD作为硬盘的CACHE，终放弃。

但好消息来自fedora20

bcache将会在该版本使用，F20关注的是普通用户使用体验，所以猜想不会难于使用。

--虽然F19的3.10.X kernel已经带bcach.so但我还没有可用工具。如有实现了的朋友也请提示

######冬天的折腾

曲线实现------------------------

As you known ,S3-371 and loads of BIOS not supported boot by SSD,just got boot information from slowly hard disk.

So this is a shortcut to enjoy SSD: given a partition from HDD for /boot,rest all for /home.

given 4G for swap from SSD ,rest all for /

System boot following below:

load /boot from HDD-->load / swap from SSD , and /home from HDD.

If you want to test this plan,I suggest you must got a SSD more than 32G.

I will check it on my notebook after Oct ,if I may.

If you done that work ,please let me known.
