[APP] simple2ext_mod for CyanogenMod 11

[psyke83]

Current release: 3.0.3b [07/08/2014]

Hey folks,

I'm releasing my own modification of @OlegKrikun's simple2ext, focused specifically on providing CM11.0 support and addressing some concerns with filesystem corruption that occurred in previous versions.

Please keep the following in mind:

• You must use ext4 format for /sd-ext, or else you will probably experience data corruption.
• Linking Application Data (/data/data) is not recommended, as it can cause heavy lag - regardless of your SD card's class. This is due to SD cards having poor mixed IO (simultaneous read+write) performance.
• If the app doesn't function properly, look at the application log (third icon on the the bottom row) for more information on the problem.

3.0.3b (07/08/2014):

• Enhancement: support for moving application libraries
• Enhancement: when re-assigning the dalvik-cache, copy the existing data instead of clobbering. Saves an unnecessary dexopt pass.
• Bug fix: make sure that the boot script doesn't execute fully if /sd-ext is already mounted. Will prevent issues when upgrading S2E.
• Rewrite boot script with more generic function to reduce complexity. The script will now ensure that the /sd-ext folder permissions always match the permissions of the corresponding source folders.

3.0.3a (06/08/2014):

• Implemented support for CM11.0
• Removed filesystem tuning (tune2fs) in mount script, as it can cause filesystem corruption
• Removed prebuilt e2fsck binary - always use the system binary for maximum compatibility
• Removed "mount as ext4" option - the script now mounts /sd-ext as ext4 by default. This is the most stable configuration for CyanogenMod, and avoids user confusion.
• Minor enhancement - when the app needs to install the mount script, it will also execute the script. This avoids the need to reboot your phone after initial installation of S2E; the app will be immediately functional.

Caveats:

• Only tested on CyanogenMod 11. Will not work on older revisions, as I was forced to remove some compatibility code. I hope to solve that soon.

Awesome :good:

It's great. .BTW, are there any options not to move all system and framework app data and dalvik cache?. .I only want to move those for third party apps. .

No, it's not possible with S2E due to the implementation of the app/script (mounting entire folders as bind-mounts).

Generally speaking, I don't recommend to move /data/data, as it can cause a lot of lag. With everything but /data/data selected, my device is still reasonably smooth and the capacity needs for /data/data are not too limiting for me.

Awesome.. Thanks a lot. Just one thing, can you please add the option to link library files too? Because, this is my current configuration & space usage. (This is without Firefox or Facebook. I usually use both of them & they take about 30mb each in data)

Another thing, those readhead values & I/O shedulers are app default. (App changes these values without asking) Are these the optimal values & are they need to be changed in the first place?

 

[psyke83]

Yes, that will be added soon. I'm going to rewrite the script to make it more generic, which will make adding additional folders (such as app-library) easier to implement.

Version 3.0.3b released. Added support for moving of application libraries and some miscellaneous bugfixes/improvements.

Done!

I would prefer not to add scheduler settings to this app. This is already configurable via Settings -> Performance -> I/O Scheduler.

What differents this script with int2ext?

I need to see a logcat taken after you try to install the package.

Your /data partition has 114MB free, and your dalvik-cache on /sd-ext is 126MB. The app is working correctly.

This post of yours is more like off-topic here. Post in the correct thread (general discussion thread). This thread is for development & support related discussion of the s2e_mod app (by psyke83) and not for support of link2sd.

Status 7 error can have many causes. So we simply can't help you w/o a recovery.log. For a successful installation, follow instructions given in first post of totoro's CM11 DEV thread.

Moreover, psyke83 already said (in general discussion thread) that a data wipe is recommended before using this app if you are using any other apps2d apps like: link2sd, mount2sd, etc.
