Sluggish/unusable performance after apps2sd on Cyan 4.2.2

I got a shiny new class 6 16GB sd card. I partitioned it at about 15.5GB fat32 and 512 ext2, using the info in cyanogen's wiki: http://wiki.cyanogenmod.com/index.php/Apps2SD_On_CyanogenMod
From there I did the ext3 and then the ext4 updates.
Although I've searched for answers for a few hours now, I've been unable to determine why the device slows to a crawl at each point of user interaction at this point. Even unlocking the screen can time out...
I backed out the changes and copied the apps back over to internal storage and everything is zippy again, so at this point I am looking for suggestions. One thing I noticed was that when I used parted to delete the ext partition so the apps wouldn't go back to the card on the next boot, it still listed the ext partition as ext2. Can someone running ext3 or 4 let me know whether parted lists their partitions as such or if they are always reported as ext2?
What other techniques should I try? I would very much like to make this work as I get constant low-space warnings in my current setup. Thanks.

just used parted to check and it says ext4 .... try using this guide .. worked really well for me to partition my sd ... also if you're having all these problems try wiping dalvik-cache and even data and your ext* partition if it comes down to it

What recovery image are you using?

amon ra's 1.2.3
EDIT: lol thought you were the OP

A more careful walk through the partitioning process and I can confirm that everything works as expected, as well as confirming that if upgrade_fs fails, then ext2 is a total dog. One particularly confusing thing was tracking down whether a swap partition was needed or not, but on the latest cyan roms it isn't so I skipped that one.

app2sd?

I'm using warm donut, flashed to the phone.. before hand I was using haret until I felt everything was stable enough.
My SD card is still partitioned the old way, 7.4GB fat32, 512M ext3, 32M swap
Is there a way to enable app2sd with warm donut so I can get more room? it might just be the fun of something new for now, but watching the free space for apps going down way to quickly

i second this, I would love to do apps to SD

I think it should be do-able now that we have the automount program that allows access sd card system and user simultaneously.

yeah you guys would love apps2sd...it's cool on my hero! im glad to see all of the android development going on here.

If you guys want to do Apps2SD, you'll need an ext2 partition on your SD for it. Native Android devices have had some trouble with Apps2SD, so it's just been rewritten by Chris Soyars and Cyanogen -- instead of the WesGarner method that had been used previously. I suggest using their code as it's battle-tested.
Here's the relevant code at github, as you can see it's been recently updated:
http://github.com/cyanogen/android_vendor_cyanogen/tree/eclair/prebuilt/common/etc/init.d/
HTH

I have app2sd enabled in my eclair build.
If you want to use it you must have an ext2 parition on your sdcard. than use my spareparts app to enable. Reboot.. wait... and there you go.

Can we get this going in your build Myn?

It's something that's built into the build, for msi's eclair he's got some extra things built into it. But it's not something you can just download

Thanks for the quick reply.
This is starting to be not worth it and I am thinking I am glad that I was able to try android on an older phone because I dont think I will be getting an android phone when I upgrade in 6 months. Getting it so I can load apps to the sd card is WAAAAAAY to much of a pain I have tried a couple of tutorials and still cant get it to work.

All you need to do is create a ext2 partition on your card and install system to nand and data to ext 2 partition. You can create as big of a partition as you want.

I used gparted to create the partition and formated it to ext2.
The second part you are talking about install the system to nand and data to the ext2 partition. I have installed Myn’s Warm Donut - [RLS 4 - 03/16/2010] nand version and thats where I am at right now. Do I need to move the data folder to the ext2 partition that I created? If yes when I connect to my PC running windows 7 I cannot see the ext2 partition that I created with gparted.

use the norootfs installer and set your data to NAND, hit data backup, then set your data to ext2 and hit data restore.
Windows can't read ext2 on it's own

there you go much better answer then mine. Thanks man

would using ext2 partions make the build run smoother?
what are the benifits over NAND?

are you sure you need to have your data on the sd card? I was running apps2sd with mssmison's v7 eclair, and both my data and system were on nand, only the apps2sd was using the ext2 partition. i don't think it cares where your data.img is, just as long as you have an available ext2 partition; correct me if I'm wrong.

Ok making progress with your suggestion after 2 days of reading and failure -- lol.
I am now able to install apps to the sd card. However when I was trying all kinds of things to get this to work I made my 8GB sd card partitioned 6.5gb fat 32 and then made two ext2 partitions evenly split.
So do I need two ext partitions?
And as soon as I made the change and was able to install to the sd card I can no longer sync with my PC. Its not a huge deal because I took out the micro sd and placed it into an sd reader and my PC could still read it. So I am guessing that its something that I changed that is causing the phone not to sync with my PC.
Any thoughts

How to install data partition on sdcard partition

I install a lot of application so I constantly run out of space on NAND. So I tried to install Myn's Warm Donut using the following method so the system stuffs will be on NAND and the data will be on the sdcard. It is slower but I can install lots of applications now.
Requirement:
-You have to have Myn's Warm Donut or other android rom installed already on NAND. This means that both the system and the data is on NAND.
-A USB reader for your micro sdcard
Overview:
The main steps are 1) install adb 2) partition your sdcard into three partitions 3) reinstall the rom.
Steps:
1- Install the Android SDK here http://developer.android.com/sdk/index.html. This will give you the adb tool which is a remote terminal program. You will have to locate the adb binary to run it.
2a- Connect you vogue to the desktop. Make sure that USB debug is enable on the vogue. It should be by default.
2b- Run the adb:
Code:
adb shell
2c- Repartition the sdcard using parted. You need some experience with parted which is very popular in linux. Remember, this step will destroy the data on the sdcard.
Code:
parted /dev/block/mmcblk0
print
At this point you should see the list of all partitions on the sdcard. For most of you, there will be one partition. Remove all the partition using the rm command with the partition number.
Code:
rm 1
Now your print should return empty. So create three partitions using the following commands. Basically, you want three partitions. The first one is your sdcard folder which you always had. The third one is for your data. The second one is just filler because the current installer only install to the third partition.
Code:
mkpartfs primary fat32 0 6500
mkpartfs primary linux-swap 6500 6756
mkpartfs primary ext2 6756 8168
set 1 lba
Note that the size is depended on you. I want around 6.5GB on my 8GB card to be the sdcard partition for musics and videos. So what's left is around 1.5GB for the data partition. I just give the filler 256MB so maybe I can do something with it later. The partition number might be different with other rom. You have to play with it.
After this step you should see something like this when you do print:
Code:
Number Start End Size Type File system Flags
1 32.3kB 6500MB 6500MB primary fat32 lba
2 6500MB 6756MB 256MB primary linux-swap(v1)
3 6756MB 8168MB 1412MB primary ext2
Now you can quit parted and exit the console by:
Code:
quit
exit
3a-Turn off your phone and put the sdcard into a USB reader so you can copy the andboot installation files over.
3b-Put the card back, run the installer and choose the data on sdcard option. You should be good to go.
As you usual, you are solely responsible for your phone and your data.
Hope this helps.

I have another solution in the works that will solve the out-of-space on data very easily on ANY build and also have some other nice advantages: http://forum.xda-developers.com/showthread.php?t=750768

So you put the apps on to ext2 partion and the data stay in NAND? In that case it would be better. The problem for the vogue is that the installer on the Myn's rom only put everything on the data partition on to an ext2 partition. On the vogue other rom is slow IMO. Maybe someone can separate the data and apps in the next build?
Anyway, do you know how can I extend the system partition so it can span to 256MB? Right now it is only 128MB because the data presumably should extend the other 128MB.

Hi csbert,
I am new to ADB. When I typed adb shell, I got device not found. Maybe I need a driver or something? thanks
update: I think I found the instruction on how to obtain the usb driver, going to try now

When you connect to vogue to your computer, it has to say "USB debugging connect". If it doesn't, maybe you need to enable USB debugging in Settings -> Application Settings -> Development.

i am looking for a good free partition program for windows xp that can partition my sd card from a card reader
i have used paragon partition but it always ask to restart the pc and then partitions the sd from there
i have had it causes my laptop to crash twice now and both time had to have a friend repair my laptop
i am looking for a program that can partition the sd with out restating the computer if that is possible
thank you

Hi,
I don't think you can partition the sdcard for the phone using an xp computer. That's why I wrote this instruction. The partition android uses is from linux. You can try a linux machine but i heard that doesn't work. You can still connect to the phone using adb and format the sdcard as I explained.
Cheers

Installing tremers Froyo on ext2 partition

I found tutorial how to use ext2 partition on SDCARD for haret.
http://android-devs.org/forum/viewtopic.php?f=56&t=194
I created this
2 GB Fat32
1 GB ext2
1 GB ext2
so i have 4 GB disk and 3 partition just as its on tutorial
But after launching haret it should asked me
Press VolDn to launch Installer (to use ext2)
just after the
Checking for partitions
but in my case it just continue with installing without asking me and its uning only fat32
Any suggestion???

our rootfs doesn't have the install function, someone must edit the rootfs to boot into EXT partitions first!

I just copy rootfs to the / of the ext2 and system to /system, and then edit the init script so it remounts properly.
When I start doing partitioned releases I'll try and make it easy, probably by distributing prebuilt images by card size (4G, 8G etc.)

I talked to phh yesterday.. he said ext2 and NAND booting have no effect on stability, performance and battery life. (rhod nand booting has been working for one month)
Performance could change but it would be less than 20%.
So I pray that someone will find the standby killer

So i need only one ext2 partition

True. I think they also had an incorrect mount option on the rootfs until recently that slowed loopback performance. I think my last (unstable) release contained the fix for that.
For my own AOSP device tree I'm determined to start fresh without the rootfs and loopback crap. Maybe not a big performance gain but easier to 'get around' system wise.

off the top of my head, init.etc/init.froyo.rc and there is a line which tries to mount root as yaffs (flash). Not too hard to find.
You might want to have another ext2 for /data though.

How do I partition my micro sd card?
please excuse my bad English
I use translator

The easyest way for me. Download a release of Ubuntu from ubuntu.com and burn it to cd or make bootable USB. Boot live cd and partition from there.

wouldn't it be easier to download a live CD of gparted?

System Rescue CD is my favorite for partitioning tasks. Should work on your sdcard.
Over in the raph forum, e334 posted a guide on partitioning ext2 from Windows

Partition SD card on Windows for people who can't be bothered to do it properly ;)

Firstly, BlaY0 has a great tutorial on how to do this properly, I suggest you do that to learn something.
Secondly, I cannot confirm that this is 100% safe. BlaY0's method should be 99% safe, I don't know about this as it is all automatic. BlaY0's method is tried and tested, this is not. I only used this method as I had a new SD card and I was in a hurry (exams coming up ) and I didn't have time to remind myself of BlaY0's method, and CWM only allows you to create up to 512mb partition. Also, I had a new computer, and I don't have time to set up ADB all over again.
Anyway, this is a method for people who don't want to use ADB to partition their SD card for A2EXT or DATA2EXT (a.k.a. apps2sd, etc etc), and are using Windows. If you're running linux, you could use something like gParted to partition it, not sure about OS X though. This method will allow a Windows user to create an EXT partition on their SD card alongside the FAT partition.
1) Download and install Minitool Partition Wizard, from here.
2) Open the program and delete all partitions from the SD card (which you will have inserted into the computer using an adapter or something). DO NOT DELETE THE PARTITIONS FROM THE HARD DISK! MAKE SURE YOU KNOW WHAT YOU'RE DELETING. Oh, and make sure the SD card is backed up
3) Create a FAT32 primary partition. You decide how big you want it, but I'd advise you leave 1024mb (1gb) for the EXT partition.
4) Create an EXT2/EXT3/EXT4 (you decide) primary partition. Use up the rest of the space on the SD card.
5) Click assign/OK/whatever and wait for it to complete
6) You now have your partitioned SD card ready for an A2SD ROM!
7) You need to assign a drive letter to the FAT32 partition. Not sure about the EXT partition. At first I forgot to do this and my card didn't show up in Windows, though Partition Magic can still see it.
Like I said, do yourself a favour and use BlaY0's method here, but if you're lazy or you don't have time or ADB doesn't work anymore, use this.

Nice one m8. You mentioned that CWM doesn't offer adding partitions bigger than 512 MB. Well, you're right but that's why I made a customized version of fake-flash that can do bigger... to 1 GB. It can even add second ext partition for some exotic types of data2ext. On top of that I added auto block alignment which is described in my guide (the manual one) so no more calculations and manual labour

Didn't know that, good to know, for those of us still using data2ext, this is important...

Wish this was up earlier, spent an hour repartitioning my card using parted.Couldn't upgrade to EXT3 and ended up using CWM 3.0.2.8 to do it instead lol

What CWM is using under the hood for partitioning is actually parted.

Tried it but it didnt work not sure what the problem is...
formatted my SD to FAT 32 and reserved 1G for EXT3 both as primary partition in the Mini Partition Tool
Plugged it in my phone,
Ran ADB shell
# a2sd --enabled, rebooted
on reboot nothing seemed to have changed... went back to ADB shell
tried a2sd --free it says A2Sd is not active ...
a2sd -- enabled again and it says it is enabled but not active
so im guessing it cant read or recognize the EXT3?!
Any clues... i didnt want to move my Dalvik to SD ... should I try EXT4 or even EXT2?

It has been mentioned here like a gazilion times, boot up your device with logcat and see the first few lines...there is your answer!
Google how to wait for the device with logcat

1) Downloaded and installed Minitool Partition Wizard from your link. I got the free home edition
2) backed up my SD card and Open the program and delete my SD card partition ( which is in a card reader)
3) Created a FAT32 primary partition of 69xx MB and left the rest 1024 MB for the other unallocated space
4) Right click on the Unallocated Space to create an EXT3 as primary partition with the default cluster size.
5) At this point, it showed 2 partition on my SD, one with the drive letter for windows FAT32, and the 2nd one Ext 3 with 1GB and Primary. Clicked OK and Apply and wait for it to complete.
6) once complete , put it in phone, plugged usb and ran adb shell
7) ran a2sd --enable, it said reboot phone.. i made a mistake to reboot by adb the first time but then did the whole process again a 2nd time using reboot from the phone....
Tried logcat using this command "adb -d logcat>mylogfile.txt"
couldnt find the file anywhere ... if i dont redirect to the txt , it goes too fast to read and there's soo much debug messages what do i need to look for?
I thought it would save me time to get it done through windows... but its taking me as much time it w0uld probably get me with the manual way...
i'll give it a try tomorrow...
8) rebooted fine, and i was still low on space.. so went back in adb sheel to check a2sd --free but this is where it says not active..

Tbh I'm really not sure. One thing I forgot to mention in the guide is that you should assign a drive letter to the FAT32 partition or it won't show up in Windows. I didn't assign one to my EXT4 partition though, and DATA2SD is working great for me. Try deleting all partitions from the SD card and start again. It'll only take 10 minutes, and if it still doesn't work just use the manual way.
Sorry.

Yeah i assigned a drive letter to FAT32...
Also the FAT32 , was my first block allocated partition, the 2nd partition was EXT3... i will redo the whole process and recreate EXT4 instead.
"DATA2SD is working great for me" ... you mean "A2SD working great for me" ... right? unless i'm missing something else that i needed to run..
ps: I recalled, after it was not working, i took out the sd and put it back in the reader to open MiniTool, it showed EXT2 instead of EXT3 ( which i was sure i chose )... and what's weird is it was reporting used space like 41MB... so obvisouly, the ROM wrote something on it...
Formatting it again to EXT3, didnt delete the 41 Used space, but it did convert it back to EXT3 ...probably nothing but mentioning as well

Yeah i assigned a drive letter to FAT32...

I suggest you start over, something seems to have gone wrong.
A2SD is where the apps are stored on the EXT partition.
DC2SD is where the dalvik cache is also stored on the EXT partition.
DATA2SD is where the entire /data partition on the phone is stored on the EXT partition of the memory card.
Partitioning the SD card with a FAT32 partition and EXT partition is done first, then you decide which one is for you. DATA2SD does have one or two issues, such as the risk of corruption - you'd then have to completely reinstall the ROM. A2SD and DC2SD are fine but I still found myself running out of internal memory.

i gave up and used ROM Manager to create my partition ...i couldnt set it to 1G because 512MB is maximum but it was painless to create.
it asked me to create a swap partition... i've read somewhere that swap partition is useless or barely used in newer android os? do you guys have any swap partition if so how big are they?
Also, did you move Dalvik cache to sd? isnt it slower on SD? i mean shouldnt dalvik cache be on RAM whihc i assume is faster than any external sd?
thanks for your insight

I used the full DATA2SD, which includes Dalvik2SD.

ok so sorry for a double post but im having an issue partitioning.
32 gb card san disk brand new
primary Fat32 10gb
primary Ext2 rest of space
once mini tool is done it sats successful but shows the sd card as Bad disk?!?
is there somthing im doin wrong? is used this guide here http://forum.xda-developers.com/wiki/SD_card_partitioning
all help deeply appriciated
Acer Iconia Tab A110 rooted, Cwm, 4.1.2

Can you actually have a 22gb ext partition? This might be something to look into to see if you can do it.
Edit: this got me interested so I searched myself, yes you can but apparently it depends on the chosen block size and hardware limitations, so u may have an issue with either.

Firstly, BlaY0 has a great tutorial on how to do this properly, I suggest you do that to learn something.
Secondly, I cannot confirm that this is 100% safe. BlaY0's method should be 99% safe, I don't know about this as it is all automatic. BlaY0's method is tried and tested, this is not. I only used this method as I had a new SD card and I was in a hurry (exams coming up ) and I didn't have time to remind myself of BlaY0's method, and CWM only allows you to create up to 512mb partition. Also, I had a new computer, and I don't have time to set up ADB all over again.
Anyway, this is a method for people who don't want to use ADB to partition their SD card for A2EXT or DATA2EXT (a.k.a. apps2sd, etc etc), and are using Windows. If you're running linux, you could use something like gParted to partition it, not sure about OS X though. This method will allow a Windows user to create an EXT partition on their SD card alongside the FAT partition.
1) Download and install Minitool Partition Wizard, from here.
2) Open the program and delete all partitions from the SD card (which you will have inserted into the computer using an adapter or something). DO NOT DELETE THE PARTITIONS FROM THE HARD DISK! MAKE SURE YOU KNOW WHAT YOU'RE DELETING. Oh, and make sure the SD card is backed up
3) Create a FAT32 primary partition. You decide how big you want it, but I'd advise you leave 1024mb (1gb) for the EXT partition.
4) Create an EXT2/EXT3/EXT4 (you decide) primary partition. Use up the rest of the space on the SD card.
5) Click assign/OK/whatever and wait for it to complete
6) You now have your partitioned SD card ready for an A2SD ROM!
7) You need to assign a drive letter to the FAT32 partition. Not sure about the EXT partition. At first I forgot to do this and my card didn't show up in Windows, though Partition Magic can still see it.
Like I said, do yourself a favour and use BlaY0's method here, but if you're lazy or you don't have time or ADB doesn't work anymore, use this.

Hahah! Thanks for you detail guide. It is so helpful for me!
