[Q] noob question - created ext4 partition on SD, but how to use it?

Hi,
I've created an ext4 partition on my SD with the intention of using it to store apps on
I used the gparted method described in http://forum.xda-developers.com/showthread.php?t=1016084
Now I've flashed a couple of ROM's (Oxygen, Redux and CM7) but have no idea how I can put apps on it
Additional question:
1) if you do a data, cache/dalvik wipe will the apps on the ext4 partition also be deleted or will they remain on it so you can reuse them in another ROM
2) I've rooted and s-offed my stock rom, can I use the partition I've created here as well? and if so, how?
thx

on all 3 roms youve mentioned you tried, app2sd is automstically setup on rom install. so you are already using app2sd.
1. yes if you wipe dsata, it wipes your apps on ext 4 partition
2. and yes, your aready using your partition once your using a app2sd rom. specific roms allow you to push your dalvik cache to your partition but it is not reccommended as it can slow donw your phone.

hi,
thx for the feedback, can I install app2sd on my stock froyo rom somehow?
I'm rooted and s-offed

extra test: I've installed Leedroid with app2sd
when I install an app from the market my internal memory decreases and I cannot move it to SD card
I've created a 500mb partition, should this be visible as "internal memory"?
cheers

Some apps still need some space from the NAND internal memory.

Nope. But if you download "Quick system info" from the market, you will see where it's written A2SD your external partition and its used space.

If you are like me and want to install lots of apps app2sd is not good enough sorry I was on Leedroid superb ROM but I soon ran out of install memory because even if you move app2sd say you have 20mb app and move it to SD it will move like 16mb to SD and 4mb will still be on phone.
Best way is Data2SD I use startburst and have 2gb ext4 and my phone thinks it has 2gb internal memory
Make sure you backup and have a SD card class 4 and above some say class 2 fine I dont think so.

[Q] Question about Sense Roms

I was hoping for some help..or even a point to the correct thread to find the answer:
How can one install any of the newer sense 3.0+ roms and still keep all apps without the phone crashing? The roms are easily between ~250 - 350 mb in size and there is no room left over for apps that I have saved in back up. I know I can move them to the sd card but I never get the chance to once i restore them due to the phone crashing. I have read about formatting the sd card but I really don't know how.
Is there someplace I can find this?
Thanks in advance

http://forum.xda-developers.com/showthread.php?t=1121538

So I followed the guide and it worked perfectly. The roms finally work and don't crash. However, now I only have about 20 - 40 mb free. I try to move my apps to the sd card using the function that comes with the rom, but it says my sd card is full. I have about 6 gb free on my card. Any idea why that's happening or how I can get around that?
Thanks again

Unfortunately this is just an inherent flaw of the Evo; the internal space is so small that you can't really enjoy a big Sense rom that uses 3.0 features and have a lot of apps. Only way to get all the room back is to flash a smaller rom.

Format your SD card with an ext3 partition. Make it 1gb or whatever size you desire. Most Sense ROMs support a2sd where it tricks the phone into thinking the ext3 partition is part of the phone internal storage. You can install as many apps as you want with the apps stored on the SD.

Thanks for the replies. I've formatted the sd card in ext3 and made it 2 gb. I wish it had more internal space. Any idea why its saying my sd card is full when I have over 6gb left of free space?

Are you using dark tremors a2sd?? If not flash that and do the following commands in terminal emulatior: a2sd install, a2sd datasd, a2sd cachesd, a2sd cachepart. Make sure you type su first
I get about 100 MB free after this

I wouldn't do all of this unless you have at least a class 6 or higher sdcard.
Definitely use dark tremors a2sd. Search for dta2sd.
If you partitioned your card to ext3, It should work automatically, but use the a2sd install command, just in case.
You can use the other commands, but you shouldn't need to. They move the cache partition including the dalvik cash to the ext3 partition, and if your card isn't fast enough, it will create lags, and other issues.
Make sure to wipe cache and dalvik before/after you flash dta2sd.

Apps2sd

my ROM is a apps2sd ROM. Ext sd is reporting use, i.e. I set 1g of ext and storage says 658mb of ext is free. But in applications my apps give me the choice to Move to SD! ?
I used TB pro to batch move apps to SD but altho my apps now report they are on SD. Ext usage actually went down after the move. Am I confusing Apps on Sd / ext ? So on roms with default apps2sd you ignore in applications that they appear to be on internal mem?

Yes ignore it. You've just moved your apps from ext to fat. Read the root memory faq in my signature

I've some A2SD questions as well. I'm on CM7 with several apps already installed. My 4GB SD card has already been partitioned to 3GB FAT32 and 1GB ext4.
I was getting low memory warnings so I applied the darktremors script (stable, not nightly) expecting it to automatically move my apps to the sd card like your a2sd guide said it would. However, I still got low memory warning, so I manually moved the app to sd card using manage applications. This however moved the apps to the FAT32 partition, and several of my apps suh as my clock widget and swype no longer work.
How to I get my existing apps to move to the SD card's ext4 partition?

They need to all be moved to phone.
The apps should automatically move to ext download quick system info to check a2sd is working.
If its not try "a2sd reinstall" from terminal emulator.
Dalvik-cache is not moved by default and takes up a whole load of space so don't forget "a2sd cachesd" too
Sent from my HTC Desire using XDA App

OK, I thought the a2sd would move existing apps as well, didn't know I needed to "a2sd reinstall". Can I do the reinstall through an adb shell or do I need to download a terminal emulator?
I don't have a Class 4 card, it's a generic card and I don't know what class it is, so should I move the dalvik-cache to the cache partition using "a2sd cachepart" rather than "a2sd cachesd"?
Do I need to wipe cache and dalvik-cache before running any a2sd commands such as reinstall and cachesd/cachepart?
Lastly, do I need to reboot the phone after running these commands?
Thanks.

Ive never seen any performance issues even on class 2 cards. Keeping dalvik on NAND may give a miniscule performance increase, but I think its so negligible, you wont notice. But put it where you want. I recommend card though as you need the cache partition for downloads and as it fills with dalvik, it will limit the size of apps you can download from the market.
a2sd reinstall is for if it doesn't work properly. Its always the first thing to try. Then move dalvik. The way dalvik move works is that it wipes dalvik, moves the location then reboots the phone (rebuilding dalvik so expect delays when booting up the first time). For this reason its best to use "terminal emulator" from the market.
Hope this helps.

Alright, thanks! Will try reinstall and moving dalvik cache to the sdcard. Might get a new faster card since 4GB is getting tight anyway.

Tried the reinstall and it seemed to work. I had to move my apps back to the internal memory in 2 batches since I was running out of internal memory. So here's what I did
1. Move batch 1 of apps from sdcard back to internal memory
2. Run a2sd check in adb shell
3. Run a2sd reinstall in adb shell
4. After phone rebooted, checked my storage to find about 50MB of internal space left (woohoo!)
5. Move batch 2 of apps from sdcard back to internal memory
6. checked my storage to find still about 50MB of internal space left. I guess this means a2sd automatically moved them to the sd-ext partition?
When I ran a2sd check in step 2, the output showed that my ext partition type was ext2 rather than ext4 which I formatted the sd-ext partition to. Is this a mistake?
Will try moving dalvik-cache perhaps this weekend.
Are there any benchmarks I can run on the sdcard to make sure it's fast enough for dalvik-cache? Perhaps HDTach/CrystalDiskBench/ATTO/AS-SSD Bench/etc? There aren't any markings on the sdcard that indicates its class. It's a generic HP 4GB sdcard. Will a "dd if=largefile of=/dev/null" for read and a "dd if=largefile1 of=largefile2" for write work?

I've never known a card too slow for dalvik. Just move it. You can move it back again
Sent from my HTC Desire using XDA App

I believe the ext2 is due to some error with a2sd check. I encountered it too when i used the command and i was using an ext4 partition.
As for dalvik, try moving it. If it too slow then move it back.

Sorry, yes its a bug, fixed apparently in the latest BETA.

Don't think I'll be playing with the phone for a while - it's my wife's phone, and it took almost a week for me to figure things out and start from stock to CM7 with A2SD...now it's relatively stable with quite a bit of internal memory available, so I think I'll keep it that way for a while.
Thanks for all the help!

Hello rootsu,
i installed a Data++ rom and now some applications that i install, not from market, disappear after a reboot. From the market it is fine but if i put a .apk in the card and install it, disappear after reboot. Not all of them. Only some of them.
I have a aura sygic gps and this is one of them that disappear after install. The only way that doesn't is to move to the card. And another one, that doesn´te have the option to move to the card, disappear after reboot.
I already wipe dalvik cache, wipe everytnhig, rom install again, etc...
What's the problem? Do you now? I've searched a lot but i cant find anything.

That's a new one on me.
Install, take titanium backup, boot recovery, factory reset, format /data, titanium restore?
Sent from my HTC Desire using XDA App

Thanks, rootsu.
And when i go to install again, say that this will replace another application.
I already made a backup, when i have stock, and restore it and happens the same.
What to do?
Edit: I do a backup, only the application, with titanium, and when restore it and say error and dont restore the application.

Hello rootsu,
i modify de hboot to sense and all problems gone. Its good now. I think thats a problem with a Hboot Data++.
Thanks.

Ah maybe yes. Good work
Sent from my HTC Desire using XDA App

Hello rootsu,
i install hboot sense and Leedroid 3.3.3 and works fine, but i have a question about cache file system. Why my cache system space is 202mb? In the AlphaRev 1.8 page the hboot sense as 40 mb. I dont understand.
The cache system space is from sdcard memory or memory phone?
Thanks

Although I am not rootSU, I feel free to answer:
I am pretty sure it uses space of SD Card. Using internal memory would be a little strange, especially we are talking about 160 MB here.

[Q] A2SDGUI not working on rooted Desire

I have installed the LeeDroid ROM v3.3.3 Port R5 on my Desire and I downloaded the A2SDGUI app from the market. But it gives an error saying phone is not rooted (which it obviously is) or A2SD scripts not found or ext partition not found. How do I make this app run on my phone? I have Superuser installed and A2SDGUI is given permission. Kindly help.
Thanks in advance!

Did you configure your SD Card with a FAT32 and an EXT partition?

Yes I did. I have followed all instructions given for LeeDroid's ROM properly. I used GParted Live CD to make the FAT32 partition and a 1gb ext3 partition on my SD card.

Followed guide on Leedroid thread to get A2SD working?

You know a2sdGUI only works with Dark Tremor a2sd scripts? I dont think leedroid uses Dark Tremor.

@Matdroid
Before installing LeeDroid I had created the ext3 partition. I presume A2SD is working because my apps are installed to the ext3 partition and not in the internal memory. Do I have to do anything else?
@rootsu
Then A2SDGUI wont work on my phone?

Not right now. Not without the Dark Tremor a2sd+ Solution in place.

If you followed leedroid guide for A2SD+, you don't need A2SDGUI.
SwiftKeyed from CyanogenMod with Transparent XDA App

The only reason I was looking for the A2SDGUI was to try to move the dalvik cache to ext partition. Or is it already in the ext partition in LeeDroid ROM? I dont know.
Also inspite of having a ext partition my internal memory is getting reduced bit by bit with every app that I install. I thought I had got rid of the 'lack of internal memory to install apps' problem by having an ext partition. What data is occupying the internal memory now?

Apps still take up the space on Internal memory. Thats the way it is.
You have to flash the dalvik cache script in the leedroid thread, post 1
Like Mat said, if you read the thread, you would know the answer.

I have downloaded the 'move dalvik to sd.zip' file from LeeDroid's thread. I read somewhere that A2SDGUI also does the job so I wanted to try it out. I guess I will just flash the zip now. Thanks for your replies.

As stated many times, A2SDGUI does the work... with DarkTremor's script, but Leedroid's ROM does not have it.

This place can be so much hard work sometimes

Appreciate all you guys taking the trouble of answering my questions. I really have very little knowledge of rooting and stuff. Just venturing in this field. So far I have managed to read the guides posted here and root and install a custom ROM. Now trying to understand dalvik cache and stuff.
Thanks once again.

[Q] Apps2sd not working! Please help!

It's the second time I try to configure my phone for Apps2SD, and it just doesn't seem to work! I've got a HTC Desire GSM, running MIUI 2.4.13. This time i've configured my phone to Apps2SD following the guide in this thread: http://miuiandroid.com/community/th...tall-of-miui-with-enough-room-for-apps.15808/
I did everything just like he said, and with regards to the partitions, I allocated 1024MB to one partition, 0 to the next partition, and 512MB for the swap partition. Then I chose EXT3. But there is no diference in my storage... I still only have 29MB free (out of 105MB) after installing apps.
Please help! What am doing wrong? This is really frustrating me..!

In order to work properly, the partitions must be created in this order: fat32, ext4, swap. Did you created them in this way? I suggest also to make partitions on your sd-card with gparted live or 4ext recovery (search this in the development section).
If you did it like that, in miui you have to enable a2sd:
download terminal emulator from market.
Type:
su
(enter)
a2sd reinstall
(enter)
(the phone after a while reboots)
if you want to move also dalvik to have more space (but less performance) type in emulator:
su
(enter)
a2sd cachesd

I've tried both terminal codes. Something is definitely working, because I've installed all the apps I used to have before and a few more, without moving anything to the SD card, and I've still got 27MB out of ~150MB.
Question is: If all the apps are stored on the SD card, why does the internal memory keep running out as I install more apps?

It's normal. A2sd move app (and dalvik if you type cachesd), but app's data remain in internal. If you need more space you have to choose data2sd script, it uses ext partition like internal, but affecting performance, overall if you have a low class SD-card. The best choice is to move app and, if you need more space, to move dalvik. Darktremor's a2sd is the first, most solid and stable script to do this, and it does very well.

Okay that makes a lot of sense, thank you.
I've got a class 6 microSD card. Is that good enough for data2sd? And how do I go about doing it? Am I going to need to wipe and partition all over again, or is the current configuration I've got sufficient?

Yes, class 6 is good. I have it too. But use data2sd only if you need more space. If you don't, don't use it, your phone may lag, have less responsiveness, etc..
You can find MIUI-XJ in developer section that has data2sd implemented.
Also you can try other script like m2sd by dk_zero-cool and xa2sdx by amarullz.
I never use install them separatly, so read instructions in their trhead.
Maybe you have only to wipe dalvik and cache but I am not sure.
