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?
Related
If I performed a Nandriod back-up while my file system was EXT4, can I restore it anytime or I should convert the file system from my phone to EXT4 before I restore ?
So my daily build is the CM7 nightlies.
I have pretty much all my apps on my ext3 partition. However, if I want to flash another ROM (aside from another nightly) I pretty much have to wipe. Wiping also wipes the ext3 partition.
I do do a nandroid before wiping, and it does back up the ext3 partition, but when I restore it doesn't seem to restore the ext. Also for some reason, after restoring I am unable to install apps at all to the ext3 partition, and I have to format the whole sd card to fat32, then make a ext3 partition again.
I actually kept getting hotboots after restoring a nandroid whenever an app would try to install. This was after I installed dta2sd.
So how can I backup a ROM with info on an ext3 partition, and restore it after wiping the partition.
I guess you're using ROM Manager with its default recovery.
Use AmonRa's recovery.
On the stock GB ROM, Link2SD requires a FAT32 partition to move the App and DalvikCache to the SD.
EDIT: Actually requires FAT32 OR EXT2 for stock...
Titanium backup requires an ext2/3/4 partition to use the Data2SD feature.
Is it possible to do both of these on a stock rom? Or use some other method to get the App, DalvikCache and app data to the SD without flashing another ROM?
I will be doing this for 3 of my family's phones and would much prefer to not have to flash ROMS and them have to put in extra effort afterwards.
I promise I've searched so apologies if this has been answered elsewhere, the closest I could find was http://forum.xda-developers.com/showthread.php?t=1605006 which didn't answer the question...
Thanks in advance!

I have created two partitions, one FAT32 and one EXT2 using MiniTool Partition Wizard
Link2SD is correctly setup and working.
Titanium Backup has this to say:
The supported mount points for the ext2/3/4 partition are:
/system/sd/ (“classic” sd-ext)
/sd-ext/ (“Cyanogen” sd-ext)
/data/sd/ (“MIUI” sd-ext)
However none of these mount points are present (it appears to mount under /data/sdext2/) so I'm unable to use the Data2SD functionality as yet.
So the question now becomes, can I create multiple mount points for a single EXT2 partition on a Stock ROM (ideally easily!).
Install a custom kernel with init.d support.
Cf-root is the most common since it's based on stock, and preserves baseband.
After that, there's many choices:
-link2sd as you've beeb using
-cronmod or amarullz scripts (int2ext+) which mount sd partition as extention to internal memory (every app on internal gets installed to the partition).
-s2e has the option to also move data to the partition.
Keep in mind that having data on the partition will lower performance and smoothness as compared to having data on internal.

Thanks for the advice.
I have a class 10 card that I was hoping would help mitigate the problem, am I just being naive?
I was hoping I'd be able to avoid a custom Kernel (haven't researched them enough yet)
I will try and find an S5830 Stock + init.d kernel tomorrow and see how that goes, I'm still planning on Titanium Backup to do the Data2SD.
Does this init.d script mount the partition somewhere that Titanium Backup can get hold of it then?

I really can't say about titanium backups' data2sd function since i've never used it before.
The init.d script (i found cronmods' int2ext to be the most convenient) mounts the sd partition as part of /data. When making backups of apps+data titanium backup had 0 problems finding and backing up all apps. The problem might arise if the data2sd function tries to move /data (in which the partition is already mounted) to the partition.
Someone in the forum might know more details. You can always make a nandroid backup and see what happens. Good luk.
Hi..first off i created a Ext4 partitio on my SDCard..followed the guide to create one.
Minitool partition wizard says i got 6.8Gb on my mem card Fat32 primary and 512 Mb ext4 primary.
Im using SDE2.0 with oxydo-zcf kernel.
Problem is have i done correct?coz my titanium backup doest show i have a ext4 partition!
reinstall titanium backup or are you sure the partition is FAT32? i dont think so, the partition must be NTFS or something of the like
First create Fat partition before create ext partition

i tried and i give up..links2sd works way better than creating a Ext4 partition q_q
okay bro, it depends on your taste and style
Hi guys Do I need a special version of int2ext in order to use it with Jelly Bean rom (in particular CM 10.1)? An ext4 partition will be fine for this use? Last but not least: to install this script is needed a special procedure (like mount /system and /data in recovery)? Thank you for your help and time Have a great life, peace!

1. Int2ext scripts work in JB
2. .ext4 is the best option
3. The procedure is always the same:
First of all create you sd-ext partition using MiniTool Partition
Code:
1. Backup your current data (optional)
2. Boot into CWM/Go back to CWM menu
3. Flashing the script:
>>> mount data
>>> mount system
>>> mount sd-ext
>>> format SD-EXT (YOUR EXTERNAL PARTITION, NOT YOUR SD!)
4. Flash the script!
5. Reboot system

Thank you so much for the fast and super-detailed answer. One thing I don't understand the reason why: the ext partition I crate in sd card with my pc is empty so why do I need to format it again with CWM?

You can create your sd-ext using your pc or CWM, I advise you to use your PC (MiniTools Partition). It's safe, easy and you can choose .ext4 format
Using CWM >> Format sd-ext command will wipe your sd-ext data, so don't worry about "re-format" your sd.ext, it won't change your sd-ext's system format
The best, the safest & the easiest way to create a partition on your SD card is always via your custom recovery. You can format it to the EXT4 file system using the EXT4 conversion tool by PSDNA. Mini partition tool killed my brand new 4GB class 4 SD card.
Also nothing special for Jelly Bean as @Viper The Ripper said. It is just the same drill & yeah, cronmod scripts support all android versions & the flashing procedure always remains the same. I recommend you to use INT2EXT+.

I created succesfully a 768mb EXT4 partition with Minitool Partition flawlessly. First I formatted the SD card with Windows. Than into Minitool Parition I deleted the whole FAT32 partition, created a new FAT32 partition set as active with 768mb unallocated. Last thing I did was allocate that 768mb as EXT4. All partition are created as primary, not logical. Also used diskinfo on android and got that 768mb working without problems. Hope my steps are good hints for you to avoid other dead SD cards
