converting file systems

if i backup my rom and ext2 partition on my sdcard using switchrom then convert to ext3 then restore the rom and ext2 data on the new ext3 partition will this work or will the restore cough up on me because it was backed up as a earlier file system?

Well, If I´m not wrong, ext2 is the primitive file system used on linux based system. ext3 and 4 are evolution of it. I´m using ext4 on my X8 without any problem, but it depends on kernel support.
You could get more information about file system here.
I´m using link2SD, besides the rom have App2SD native, but it wasn´t installing apps on sd-ext partition.

Yes,you can.After that you can use S2E or Link2SD to config SD-ext.I gess you flash New Experience rom 9.9.1,it already has S2E and very smooth.

it's strange:
I use last CWRM 6.0.2.7 for mini by dany

thanks... I tried to use it before and it creates a right ext 4 partition, but the rom (lenio rom v4) does not recognize the partition
I tried to label the partition "sd-ext" or with no label
but in both modes it does not work

incredible... I did the ext4 by minitool but the a2sd on lenio v4 does not recognize the sd-ext
update:
created ext4 by minitool partition wizard, but it seems that phone can't recognize it, coz the rom does not see the partition
is there something to do to make the phone create/see ext4 partitions?

tried the last attempt, with another CWM (5.0.2.8 touch ext)
I partitioned the SD, choosing ext4, but when I control, it's ext3
why that???

Some possible problems,

maybe the CWM failed to format it with ext4 file system,
or the ROM you use failed to identify ext4 file system, some guys told me there are ROMs that don't support the ex4 yet, you may want to read your ROM specification,
or somehow the ROM need additional script to read ext4 file system properly,
recently I've tried more than 10 times partitioning my SD cards, but most of it failed in attempts,
it won't be mounted as second partition, therefore I can't use Link 2 SD properly,
My ROM is PAC 22.1.0
I've tried partition tools: Minitool, CWM 5, AParted (SDCARD Partiton Tool) app, checked the partition table with Partition Table app, trying to mount second partiton manually with Android Terminal Emulator (using "mount" command), success using CWM.
I've tried ext2, ext3, ext4 partitions, but success only with FAT32 file system,
I think in the process I've delete some media in /system partition, maybe it creates problem since Link 2 SD need to modify some files in /system partition to mount the second partition,

I tried with Lenio vQuattro, partitioning with minitool, the sd-ext was correctly partitioned as ext4, but the phone did not saw the sd-ext. The rom is done to use only ext4.
So I went back to the most recent cm 10.1 (with ext3 and int2ext+) because this is my only phone and I need it to phone

Better use mini tool partition wizard..
You can choose the type of part,like ext2 ext3 or ext4..

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.

Can you tell me exactly what the error is? Are you able to create the mount scripts? You only have one sd-ext partition right?

According to MiniTool Partition Wizard, yes, I have 1 FAT32 (about 30GB) and another Ext3 partition. However, the device doesn't read it, and I cannot partition through either TWRP or CWM. I'm testing Cronmod on CM10.1 now, will update.

TWRP or CWM should not be used to create a new ext partition if your sdcard already have another ext partition. Meaning you should have only one ext partition in your sdcard. So delete the ext3 partition and the fat32 partition, then create a single new fat32 partition on the 32BG sdcard. Now use the recovery mod to create the ext partition. That should work. Between Link2SD and CronMod, I would always go for CronMod. Then again its my opinion. Any way if you have any problem, just post here and I'll be glad to help

Steps taken: Copied files directly through Cronmod ZIP (INt2EXtV2+) to respective places (i.e. /system/etc/init.d/) using FX File Explorer, rebooted, and it BOOTS!
Hang on a minute, let me check my disk space, it still reads '16MB free, 162MB used'. is that normal? The script has already been put into the- Wait a minute, the space just increased to 24MB free, 154MB used.
Oh my gosh. Link2SD is saying that there is no second partition.
Apparently the other init.d files are rwxr-xr-x, root, shell, but 40int2ext is rwxr-xr-x, root, root. Is that normal too?
P.S. Sorry, my Shift key is malfunctioning
EDIT: I'm manually flashing Cronmod again, instead of copying directly, as TWRP and CWM 6 didn't allow. CWM 5 works like a charm.
EDIT 2: Still 15MB free *Cries*

You should know that CronMod and Link2SD doesn't work together. Since CronMod is present, Link2sd can't find the ext partition. What is the size of your ext partition. What rom are you using now? For every 512MB sd-ext partition you need a 100MB space on /data. So please limit your sd-ext patition to 1GB max.

As a last resort, try to reflash this rom. Make sure to backup all the data. Take the rom file, extract it, put 40int2ext file inside /system/etc/init.d/ and then compress it back. Now go to CWM, do "Wipe Data/ Factory reset", "Wipe cache partitions", Mount & Storage> "Format /system" and "Format /sd-ext", Advanced> "Wipe Dalvik Cache" and "Wipe Battery Stats". Now reflash the custom rom. This should pretty much solve it. Restore all the necessary data.

I've tried that already, and the device went into a bootloop. However, I used GParted to partition 777MB sd-ext, and the rest FAT32, and it boot up after flashing CM10.1 > GApps > CronMod INT2EXT4
The only problem was that the memory remained the same, and Partition info showed /sd-ext (EXT 0.00B/0.00B)
EDIT: For some reason sd-ext doesn't mount, but formats perfectly.
