[Q] Increase size of ext3 after it has been created. - EVO 4G Q&A, Help & Troubleshooting

Is there a way to programmatically increase the size of your ext3 after it has been created initially?
For instance, if your ext3 is 512mb with 0 swap, can you change that to 1024 mb with 64 swap without reformatting the sdcard?

nope, complete reformat necessary

sd card partitions

Hi,
I wondered if there was any way to see the other partition I made with rommanager.
I did the following:
Ext Size:
512MB
Swap Size:
256MB
But I can't find anything about this on my phone.
It only says the total capacity is 3GB now instead of 4GB.
Is there also a way to undo this partition?
Thanks in advance!

you can undo the partition by setting ext2 and swap to 0

[Q] About the ext3 partition size

Hello !
Is it possible to use an ext3 partition which size is greater than 512 MB ? Thanks by advance.
Yes, but you can't create a ext3 bigger than 512 MByte with the ROM-Manager. Use AmonRA Recovery or Linux (gparted) to create a ext3 partition at the end of the SD (FAT32, ext3).
yes you can.....i currently have 1gb...and believe me you won't need any more than that even in 2 years....
i recommend you to use the gparted for formatting the sdcard

[Q] Partitionning the SD card : Ext first, or fat32 first ?

Hi all.
There are a lot of information around there related to the partitionning of the SD Card ... But I'm still a bit confused regarding the following point :
When creating an ext partition aiming at "enlarging" internal data partition, is it better to put this ext partition as first partition on the SD card, and the fat32 partition as second, or vice versa ?
As far as I know, using AmonRA recovery, I'll get no choice : the ext partition will be first.
But, if I use GpartED, I may do whatever I want ...
Thank you for your support.
Simple way
I personally would recommend using clockwork mod rather than amon ra. After you root, you simply install ROM manager and use it to create a max partition of 512 MB. Its automatic. No frills, no troubles.
After some time, if you still find the 512 MB partition to be insufficient, then you can think of using GParted to increase your partition. Use google to search how to use gparted. Anyway, the order is: Format FAT partition, then create EXT partition.
Initially i used ROM manager to create a 512 MB partition. Only recently did i increase the partition to 1GB using gparted. Learn more about using gparted before using it.
I know rom manager will only allow up to 512 mg so the best thing is use CWR and partition sdcard/ advanced. Then you can choose up to 4g

I'd actually recommend the opposite - I much prefer AmonRA over CWM but tbh I'd actually say use a GPartEd Live CD and do it there instead

[Q] ext4 What is it?!

I have been using a custom ROM for a while now and I have been seeing in the thread that many people are using ext4.
I have asked many times in the thread and recieved no reply.
So my question to you is what is "ext4" and what bennifit will it be to me as a Desire owner.
Thanks

1. Google is your friend
EXT4 is a file format used by Linux (Android = Linux). When threads talk about EXT4, they are referring to creating an EXT4 partition on your SD-Card e.g. have 14GB FAT32 and 1GB EXT4 (from 16GB SD-Card.. 1GB is always non-existent)
What having an EXT4 partition enables you to do, is to have Apps/Data2EXT scripts which move apps to the EXT partition, giving you a lot more internal space.

Moving some of the app data to the sd-card is different to having an EXT partition and A2SD.
If you activate A2SD, the system will install and store your apps on the EXT partition, and your internal memory will not be filled up, and will remain at xxxMB. Furthermore, with an EXT partition you can use D2EXT, which makes your phone use the EXT partition as the data partition, so if you have 1GB EXT4, your phone will see 1GB memory.
If you use the inbuilt "move to sdcard" function, it only moves some of the sd-card to the android-secure folder on your sd-card, however your internal memory is still used up.
In addition, moving apps to sd-ext partition doesn't break app widgets like the stock app2sd method that Gingerbread use.

Reason: With A2SD / DATA2SD / etc. Android still "thinks and tells" the Apps are still installed in the internal memory (at least this tells me my logic).

backup your sd card 1st
then use only 4ext recovery (requires s-off to change recovery) or gparted to create your partition (step 5 here)

[Q] SD Card Configuration : Ext and Swap Partition

Hey,I am going to "clean" install CM 7.2 Stable.I am done with Custom MTD Partitions and want to set up an ext partition on the SD card and move apps there.
Preparing for "S2E"(simple2ext:https://play.google.com/store/apps/details?id=ru.krikun.s2e&hl=en )
I have got 2GB SD Card.
What should be the ideal configuration for a 2GB card in terms of :
(1)Ext Size
(2)Swap size
And what should it be ? Ext2 or Ext4 ?
According to this :http://forum.xda-developers.com/showthread.php?t=1432459
“Choose Ext2, Ext3 or Ext4 for partition type based on whether your kernel supports Ext4. If it does choose it! If you don't know choose Ext2 to be safe.” Now how to find out whether your kernel supports it or not ?
Does "swap" really make any difference ?What’s up with this “swap” partition ?
It’s so confusing.Some people claim that “swap” is like virtual RAM and more RAM means a more efficient (and faster) device.
Here are the posts supporting “swap” :
http://www.mod2xtreme.com/showthrea...crease-RAM-using-Swap-File-and-Swap-Partition
http://forum.cyanogenmod.com/topic/...-the-wildfire/page__gopid__330791#entry330791
http://forum.cyanogenmod.com/topic/44675-how-to-configure-a-sd-ext-on-htc-buzz-wildfire/
While according to “Cyanogenmod” (http://wiki.cyanogenmod.com/wiki/Swap_and_Compcache ) and some member swap doesn’t make any diff .on android devices.
If that’s true and swape is useless then why so many forums going gaga over it on XDA at the first place ???It makes no sense. So bewildering.
Any suggestion ?Any help would be much appreciated.
Thanks.
You should try 256Mb or 512Mb ext2 partition as per your convenience with 0 swap size.
After partitioning your card you need to install an a2sd script and use a2sdgui app to move apps.
Or else you could install link2sd app and i guess that moves apps to ext partition without needing a script.(haven't tried it though)

Swap is used when you run out of RAM space.I dont think we need it on our wildfire.Just select 0 as swap size.create SD partition from recovery,that would be easy as you don't need to be confused between ext2 or ext4.

You've kind of answered your own question with the link you've provided, if you think swap may be worth using, backup your SD card create a swap partition and give it a run for a while, if you think it isnt then backup everything again and create a partition without it. I had swap enabled when I first created a partition but saw no benefit at all.

I successfully made sd-ext and moved apps there (http://forum.cyanogenmod.com/topic/44675-how-to-configure-a-sd-ext-on-htc-buzz-wildfire/), so now I have 170 MB of free space for new apps!!
Question: I noticed that my phone slowed down a lot.... does it depend on SD type (read/write speed)?
Which is the best type / brand of SD?
Is there any other setting I could optimize for speed, when having Sd-Ext enabled?

Moving Applications data to sd-ext slows your phone down.Don’t move “application data” to sd-ext.
I suppose you are using “S2E”,right ?What’s the format of your sd-ext ? ext3 or ext4 ?
Go through this thread :http://forum.xda-developers.com/showthread.php?t=917377
Personally, I prefer“S2E”(supports mounting sd-ext as ext4)

Yes ,your card’s speed depends on the class of your card. An SD card's speed is measured by how quickly information can be read from, or written to, the card.Speed varies with the class of the card…Class 2 (2 megabytes per second), Class 4 (4 megabytes/second),Class 6 (6 megabytes/second) and so on…

It's working great and ext3 should work fine too.
Acually ext4 provides better performance with journalling.
If you use an Old CWM recovery, it will convert it back to ext 3 when you backup/restore.
ext3=ext2+journalling
As ext4 is newer file system,new features have improved the performance and reliability of the filesystem when compared to ext3.
Journaling can be bad for the life of an sd-card (coz you do more writes).If you are not worried about life of the card, and the choice is based on filesystem performance only then ext4>ext3>ext2.
Ext4 can be used with journalling switched off.So "ext4 without journalling" will be best in my opinion.
There is a debate going on over it,check that out :http://forum.xda-developers.com/showthread.php?t=800353
