[Q] best partition for 2gb sd card (stock) ????

how should i partition my 2gb stock Kingston sd card because i am currently using Sparksmod 2.1 Rom and they require a ext3 or ext4 partition so i parititoned my sd card with a 32 mb linux swap partition and 512 mb ext 3 partition. At first everything was fine, but after a few weeksd my phone is REALLY SLOW and unstable.
EDIT: FAT 32 has 1423 MB
What should i do? Did i partition it the wrong way.

Upgrade you EXT to 4. See if that help.

Ext2/3/4 has nothing to do with slowing down, most likely it's swap, especially when swappiness is set too high ...

I was thinking about that too, but since the SD card was only 2GB, space is limited. May be making the swap to 128MB instead of 62MB. might help then. And set the swappiness to the middle setting.

It would be better to renounce on swap completely. If there is no chance, set swappiness at most to 20-30, but this depends also on your "profile", i.e. what apps you are using, what services are running, etc.

Im not even sure if my phone is using swap at all and the rom doesnt need you to have swap so should i remove the 32 mb linux swap partition then?

Oh and i checked and i am not using swap
so if its not the swap then could it be the apps2sd ext?
Cuz i read somewhere that apps2sd makes the phone take longer to run apps
and this is what is happening to my phone the apps are lagging it, when i launch them they take at least 5 seconds to load, and when i use the browser my phone becomes really unstable.

Startup time for apps stored on sd-ext may be a bit longer, but do not change over the time. Are you using also data on sd? This might be a problem, if not, there must be something different ...

how can i check if i am using data on the sd?

[Q] use SD as main storage?

This is what I am currently doing: I made a 1GB ext4 partition, and i link all my apps to that using Link2SD.
This is working and i maintain about 100MB free on my internal memory. I have seen some other screenshots of ACE users, that somehow trick their phones to thinking that the Sd partition is the internal memory and everythign will automatically install there, and in system storage it reports the total space as that of the partition and not the ~100 MB.
how can i do this? what apps do I need

that looks confusing as hell. and he doesnt even use an ace. before i try it and may ruin something, has anyone tried this with an ace

Lol. What u describe there is what the amarullz script doing, swapping internal memory with sdcard and made phone think sdcard is the phone memory for app data.

LOL, just copy and paste script and set permission.....
dont need to read the whole thread

looking at his picture, it seems like he will be saving more files on the internal memory as opposed to what im doing now where everything is on SD. is that not counter intuitive

yes, but the creator said it will improve overall performance.
the more you install app = more dalvik cache
and one day, your internal memory become full.....of dalvik cache

so is there a way to still have everything on the SD card, but also have the phone think that the 1GB partition is the internal memory

[Q] Where is my internal memory being used?

First of all, i have a S5830i rooted, odexed phone. I have linked ALL my apps to SD via Link2SD app.
I used to have around 100mb free but after a few days that became 90mb. I thought to try a wipe dalvik cache and after the reboot i had 78mb free!
I saw in many other screenshots that there are people with 130+ or even 150+ mb of free space internal memory.
How do they achieve that? Why i have only 78mb of free internal memory while i don't have any apps installed there?
I hope someone can assist me with that.
Thanks in advance.

you are not clear with your question
u saw people have 15 mb free.. and when you have 78 mb free. you should be happy

i'm sorry i misstyped i mean 150mb not 15... 78mb free space seems too low since i don't have any apps installed in my internal storage.

As far as i know, Not all app data is copied to sd card with link 2sd. Did u think about trying a Script like "cronmod" or amarullz? Or s2e app which is, in my opinion, better than link2sd.

link to sd never moves your dalvik cache and data to sd partition..
I would recommend you to use s2e if you are on CM7.x

Link2sd moves apps apk, dalvik-cache dex, and libraries lib to the partition. Data of apps stay on internal /data.
Wiping dalvik cache (from recovery for example, or with adb) causes link2sd to loose the symbolic links used to store data, which messes up your app's location in a pretty nasty way.
Open link2sd, filter your linked apps, select all of them with menu > multi select > select all, then link app+dex+lib. If there were parts of an app that weren't linked this fixes it. Reboot. Also from link2sd clean app cache.
Finally, check your data/local address with a root explorer and make sure there aren't copies of apk files you already linked. If there are copies, delete them, reboot.
Edit: moving /data of apps to the partition frees up more memory, but lowers performance, specially with sdcards class 6 and below, and partitions which are ext2 or fat32.

[Q] Help needed regarding link2sd w.r.t CM 10.1 (4.2.2)

Hi all,
Before i start, lotss of respect and millions of thanks for all the developers for their beautiful ROMs and everyone who are providing with brilliant solutions for almost every problem.
I'm totally new and this is the first time i am typing over here. Please forgive any noob mistakes that i might be doing and i'll make sure the same doesn't happen twice.
Since last couple of weeks i have started exploring my mini and i found the following issue.
At first, i used link2sd on ext2 partitioned sd card (as suggested by a link2sd tutorial) while using stock gingerbread(2.3.6) rom and was successful in installing over 90+ apps with still about 112 mb free in the internal memory.
Everything was smooth and was working fine.
Later, i flashed this Rom "cm-10.1-20130310-NIGHTLY-tass" onto my device and used ext4 partitioned sd card.
I opened link2sd and after specifying the external partition as ext4 and after rebooting the device, i got a warning message telling that link2sd failed to mount the ext4 disk. It instructed that i must reboot and try again.
After the reboot, link2sd detected ext4 partition.
But soon after filling the device with about 78 apps, the internal memory reduced to 60 mb. Also, in between while rebooting, in order to link all the files successfully onto sd ext, few apps would disappear.
Every time at boot the system mentions low internal memory and that some apps would not be working.
Boot takes a lot of time too (about 3-4 minutes).
I am linking dalvik-cache file, application file and the library file
Is there anything that i must and must not do?
Can ext4 partition be used on the mentioned ROM?
Is there any compatibility issue with link2sd on this ROM?
Kindly provide me with any feedback/suggestions.
I would be extremely grateful..
BTW.. amazing ROM.. super smooth and great performance
My first custom ROM and i love almost every bit of it

Aaaah.. now my internal memory has gone to few kb :crying:
is there any other way i can freshly install all my apps without encountering this issue? Now i'm desperate for some help

The only soln to this is flash the rom again and any scirpts like crossbreeder and then flash Int2extn4+
this script moves all your app data to extn. il have installed 20 apps and my internal memory is 1GB
give a try, search in themes and app section(thread by Ashu.bigsmoke) :good:

why d you install so many apps, install apps that are important.
i use lastest antibillos' rom, no partition sdcard, i just move my apps to sdcard using link2sd. i still got almost 30mb on internal memory. i actually can increase the empty space on it, due to some apps which are not recommended to be moved to sdcard, so i didnt move it. by 30mb on my internal, my phone is smooth, this rom is really suit my phone.
well, backinup your apps and restore em whenever you need, uninstall when it is rarely used, is another choice.
*sorry for messy english.

Thanks guys
Will definitely try as per your suggestions and will report my observation..
I was observing that the /data/app folder consisted of actual application files even though i had linked them.
I deleted all the files from that particular folder and linked the applications again. Now i can see about 80mb free.. However, during boot i still get low memory alarm and the internal memory will be almost nil for few minutes. I guess the ext4 partition is not read during boot.
Why's that happening?
I presumed that ext4 partition would be read during boot.

I read about int2ext4+ and i got to know that we need to have 100mb free internal memory for 500mb of ext4 space!!
I currently use about 1.4gb for ext4, this technique makes it impossible for me to use even 500mb of ext4 partitioned space!!
What's the need for 100 mb free space for every 500 mb external space? I didn't quite get that..

[Q] error: not enough internal memory - but I have 90MB and app is 30MB

Hi Folks,
Executive summary:
I'm trying to install an app that is around 30MB. I have 90MB of internal memory available. It won't download and complains there is not enough memory.
Gory detail:
I have a 32 GB SD card partitioned into 10GB (ext2) and 20 (FAT32) and I use Link2SD to automatically install apps on the ext2 partition. That is working fine.
There is an app in Samsung Apps, issued by the education department, that I need for my son's upcoming spelling bee. The app is around 30MB. When I try to download it, it complains that there is not enough internal memory and that I should delete some files, make space, etc.
Relevant information:
1. There is 90MB available on the internal memory and the app is 30MB.
2. The app should automatically be installed on the SD card anyway, and so not be concerned about the internal memory in the first place.
3. Other, smaller apps from Samsung Apps install without complaint directly onto the SD card.
The figure of 90MB is from Settings > Applications > Manage Applications and also from Link2SD > Settings > Storage Info. Same number.
The phone is rooted and running Gingerbread 2.3.6.
Thanks in advance.

Did you move the dalvik-cache partition?
Dalvik-cache needs space too to install and run the app so clean it and then try to install this app again

Thanks for getting back to me.
In setting up Link2SD, a new dalvik-cache folder was set up on the 2nd partition on the SD card and the default action for all new apps is to put dalvik-cache files there. There is still the old dalvik-cache folder on /data.
I used Link2SD to clear all the cache folders and got another 10 MB free of internal memory.
Running df in a terminal I get:
/data size-180MB, used-76MB, free-104MB
Which should mean that the 'old' dalvik-cache folder has plenty of room to expand and shouldn't be stopping the installation of a single new app. Again, of course, any new apps should have their dalvik-cache files added to the SD partition anyway, rather than the original one.
Is their something I'm not understanding about the dalvik-cache?
Thanks for the help.

You're right, smply I thought that your dalvik-cache partition was full and it was the reason you couldn't install anything, but it's weird :S :S :S
For this and many other reasons I don't like to use link2sd, I prefer int2ext+ script; safe, simple, fast, doesn't touch the dalvik-cache partition and keep /data in /data place
AFAIK Link2sd don't move "apps" strictly, It link apps to sd-ext partition, so a part of apps are installed in /data (internal memory) and the rest (the heaviest) in your sd-ext partition
It could be helpful

Thanks for your help.
It's my wife's phone and I'll be away from home now until next week, so can't pursue the solution any further just now, but I haven't given up!
I'll be back on this thread come Monday, and I'll definitely have a look at int2ext.
Thanks again.

It's normal I suppose due to Read/Write cycles, but it's better (less cycles) than swap partition (reduce your sdcard's life drastically)

Couldn't Install on USB Storage or SD Card
If, while installing your app, its showing "Couldn't Install on USB Storage or SD Card", then I've got just the solution. You could either fix it permanently,temporarily or do a method each time before you install your app.
Permanent Method
1) If your device is running on 2.2.1 or 2.3.6 android version, upgrade it to 3.4.5 ICS or 4.1.1 Jellybean. If the problem is solved then, don't worry, your problem has been permanently fixed.
Temporary Method
1) Backup your SD Card files and format it. Don't worry, it won't affect your partitions. I cannot guarantee you that this thing won't come up again. It may not but there is still a chance.
2) Before installing your apps, Go to Settings>Storage Info>Unmount SD Card. Select this each time before you install anything. Your app will be installed on to your Phone memory. After installing, Go to Settings again and Mount your SD Card. And of course, you could then Link your app to your partition or whatsoever...
I'll recommend Temporary Method 2 as it is would be easy for you if you're a newbie...Hope that this helped...Thanks:highfive:
