ext partitioning cwm

when we partition our sd card to ext in cwm recovery is that ext2 or 3/4? if i use gparted insted of recovery to partition to ext4 is that ok?

Cwm does an ext3 partition, if ur using DTa2sd..it can be converted to ext4 by
su
a2sd convert-ext4

Yes, it is perfectly fine if you make one with gparted or mini tools... make sure you run this command in terminal before flashing a2sd...
mount | grep sd-ext

thanks to both
what mount | grep sd-ext exactly do?
aso my gparted already see my sdext partition ext4 if i partitioned it from recovery is that possible or an error?

That command checks if there exists an sd ext partition.
I don't know abt gparted but cwm formats the card and partitions it so it should not be a prob

I used minitools for partitioning
u can go for ext4 no harm in tht
if ur using mini tool make sure u keep all partitions as primary
also ext2/3/4 wont b detected on windows so dont panic if u dont see the partitions once done they r thr meant for ur phone nt windows

Without a2sd what is the exact command to convert partition to ext4 ? It can be very useful

yeah, but "problem" is after a restore. If we convert partition in ext4 after restore, all data already in partition remain on ext3, only new data will be on ext4.
So it will be good that cwm could format always sdext in ext4

Okay, a question from me...
I have a galaxy fit s5670, running a custom rom that came with darktremor a2sd pre-installed...
I created a partition of 1024mb on my 16gb card, and have enabled swap...but the apps that I install are still going in the phone memory...
Can you please help me out???

I have installed link2sd, which seems to be working fine...
When it asked me what partition type did I have, ext3 and 4 gave me a 'partition not found' error...
Ext2 is working fine...

I believe that you are taking about the cache that will use your internal memory even if you have a2sd enabled. THough it is not recommended to do so unless needed (i.e. your memory is very low) you can move dalvik cache to sd-ext from APP2SDGUI app or though this simple command
su
a2sd cachesd
It will move dalvik cache to sd-ext.

Don't try anything eles.... Just install darktremor as said here http://yagyagaire.blogspot.com/2011/09/how-to-partition-sd-card-and-install.html
If possible format your sd-ext before installing darktermor app2sd. THen all you need to so is move dalvik to sd-ext as said above. And your internal memory will be totally empty. You can explorer /sd-ext/ folder using root explorer to see if a2sd is working properly.

After using link2sd for a day, I find that it is working, and it even allows u to specify which apps to move, and what all to move...
I did partition before using a2sd, and I understand the thing about the dalvik cache (moving which would make my device slower)...
Anyways, thanks for replying...

If u use permanent cwm ur sd-ext partition wil b backed while taking a nandroid backup.
For link2sd make ext3 partition on ur sd card. I hope u kno hw to make partitions on sd card. If nt search on google.

Actually, there are many opinions about Ext partitions and which one is the best.
I'd personally suggest you read more about them yourself (ext2, ext3, ext4).

Ok.
I make sd-ext3 using cwm, but when I make backup the cwm can't find sd-ext ??
Why ??
are there any way that allow me to backup my sd-ext, and then restore if anything happened ?

You mean this is some kind of external storage, which the system recognize like internal memory.

Ok, I've created the partitions in CWM, flashed my rom again with factory reset, vie Settings -> Performance -> Memory managmet -> A2SD I set ti to A2SD, gave the system root access, rebooted the phone and the sd-ext partiton is not mounted. I've installed the link2sd app, and choose ext3 partition, which is set by CWM, and the app say
Can't mount: Invalid Argument
Your system maybe not supporting ext3 or somthing like that.
So how to mount the damn sd-ext partitions.
P.S. I've tried via terminla with df | grep sdext3 no luck.

Or ext4, maybe there is issue with ext3 partitions and this rom. I've read an article that said that, ext4 partitions are not well supported, ext2, ext3 are supported with most of the roms
Edit: Now I saw that after reboot, A2SD is set back to none. Maybe I am having the superuser issue. I've flashed the fix, and will try again.

then try ext2

As I know CWM (in ics and jb kernels) creates ext4, so choose ext4 in link2sd and it should work fine.

Cannot Mount Ex3 Partition with CWM

I created an ex3 partition (1gb) using minitool partition wizard for using Link2SD application. But cwm cannot mount the new partition, so naturally Link2SD can't see the partition. I'm using Acecream rom 1.4.
What can i do?

CWM should not mount the second partition, Link2SD has to do that.

Format sd-ext from cwm recovery. It will format it in ext-3 format by default. Then try to get it detected in link2sd. If cwm can't format sd-ext, then try formatting sd-ext using minitool again. May be the first time partition was not created correctly. You may also try to format it in ext2 format as well and then test it.

CWM could not format the partition that i created with minitool. Because I tried re-create, shrink and reformat (also changing ext3 to ext2) but still same. As far as i understand CWM can't do format process because can't mount partition.

Link2SD should ask for creating mount scripts. Select "Ext3", then you will be asked for rebooting your phone, reboot.

Yes, Link2SD asked for mount and I selected ext 3, but it couldn't do that . It gave an error something like "unable to mount....".
I want to ask someting different. What happens if I don't create ext3 partition? Link2SD now can move the aplications on SD card. What is the benefit of creating Ext 3 partition?

MOVING to the SD card is only moving a part of the application.
LINKING to the SD card is moving the whole application (apk, dex, lib).
In Link2SD, click on menu, select more, recreate mount scripts, and select ext2.
If that doesn't work, try again and select another one.

I found the reason. We have to make primary (in minitool) the new partition. After that Link2SD automatically found the new partition.
Thank you alot again (I clicked the thanks button of course )

Make sure that the ext3 partition is a primary partition not a logical partition.

You can also create a second partition with CWM.

Partition CWM

I just have a question. Is it safe to partition my sd card in clockwork mod recovery coz I have clockwork mod 5.0.2.6 and in the advanced there is an option "Partition SD Card" and if u select it there at several amounts like 246m, 400m, 1026m, 2046m. So would it work if I do it in my clockword mod recovery.

Yes it works. Creates ext3. Backup sd contents first then copy back after.

Hi Pj_Singh
Is there any particular reason you want to create ext4 partition only? I mean Galaxy Ace doesn't have very great processor and ext4 is slower than ext2. Take a look at this: http://forum.xda-developers.com/showthread.php?t=800353

Despite the fact that ext4 is slower, it is required for most of the newest rom's/kernels to work. And the ext4 is "slightly" slower, means you wont see the difference, at least not when using a phone.
