[AOSP] LVM for i9300

[GR0S]

I'm going to make LVM possible on i9300

What this will bring to device:

• Join /Data and /extsdcard partitions (10 GB+32 GB = 42 GB of fast memory)
• Snapshots, easy rollbacks in time
• Easily resize partitions, make /system and /cache smaller, make /data bigger (even more data can be stored)

Tasks:

• Compile CM10.1 kernel with LVM2 module
• maybe: Kernel should be configured to boot android from LVM volume (somewhere in ramfs)
• Compile TWRP with lvm utilities included and partitons list updated
• Design new partiton table, for example /system untouched, /data /cache /preload removed then created in LVM
• Test

Any linux experienced guy is welcome

Although I'm not a linux expert, I reached these conclusions after some search.

You can't/shouldn't use a removable storage to add into LVM on android. Why?

With LVM, you never know where what parts of the file are located at. You pull out that card and NOTHING will save you from completely destroying the filesystem.

Exactly. Using removable storage to expand the internal isn't a good idea.

Are you removing sd card often? It's same as swap, remove card, get crash/data damage/etc.
I won't add system to lvm anyway, so ROM can't become damagedd

Yes I do. I have a 64gb microsd card and I'm using it for carrying big files such as image backups, linux ISOs, movies(to watch via HDMI) etc.
In fact this is the only reason why I have to keep buying Samsung's damned closed source buggy exynos devices

One day if google come up with a device that has mmc slot, I'll say "Goodbye" to samsung.

Also, the vastly different performance between internal and external SD will likely lead to major wonkiness.
