can anyone provide me with the terminal commands to formatting ext2 partitions
mke2fs /dev/block/mmcblk0p2
that's assuming you want to format the 2nd partition of your sd card to ext2
this requires e2fsprogs -- check here if your build doesn't have them
if you want to partition your sd card use SDSplit
if you want to reformat your already existent ext2 partition run this in terminal
su
rm -r /system/sd/*
reboot

this does not format the partition -- it removes (deletes / unlinks) all files in that directory or file system mounted there.
fairly substantial difference, but your suggestion may, indeed accomplish what the OP set out to do if that's all they wanted

I had to wipe my phone and have ext2 partition on my card but when I try the copy.sh app command it works but always hangs on the flashing g1 after I reboot the phone. So this leads me to believe its because the apps are still there on the ext2 partition and need to be removed before I could do it again.

well you can try flashing LucidREM mod that has the files for mounting it located here and instead of using the copy.sh app first try this.
$su
# cd /system/sd
# ls -la
check if the app folder is there if it is than
# cd app
#ls
check if the files are there.. and if they exist than try this
# rm -rf /data/app
# ln -S /system/sd/app /data/app
# reboot
hope that helps and it u still want to wipe the ext2 parttition than jut
# rm -rf /system/sd/*
or
# rm -a /system/sd/*

I kinda had the same question but was wondering if there was an easier way of wiping the ext2 partition? I'm kinda new at all this and am now starting to get the hang of flashing different roms onto my phone but I realized that doing an Alt+W before flashing new roms does not wipe the ext2 partition. (At least I'm pretty sure it doesn't.)
I'm not too savvy on using terminal yet..I've heard of using adb but I don't even know where to begin with that..so I was wondering if going into Paragon Partition Manager and just formatting the ext2 partition will work? Any info will be greatly appreciated.
Ok i finally have it working. I keep getting a social network force close.

there is an app on the market called lucid REM that runs his script via terminal emulator. after getting it and running it you can go to terminal and type
su
lucid -c (this wipes ext2/3 partition)
hopefully this helps you. if you are on a rom that uses auto a2sd then you will most likely getting force closes all over until you flash your new rom.
I posted a thread with steps to do it http://forum.xda-developers.com/showthread.php?t=533731
Code:
Open console and enter the following commands. Press "Enter" after each line. This wipes the ext partition.
mount -o rw /dev/block/mmcblk0p2 /system/sd
rm -r /system/sd/
[code]
Glad this wasnt deleted right away, maybe it can just be moved?
It helped because I also was wondering the best way of doing this, and now I know.
Thanks .
Odd, double post for no reason. Sorry delete this post?

-repeatedly bangs head against wall-
follow this guide but in the beginning where it says use adb and type adb shell
just be in recovery console and hit enter then from there out all the commands should be the same.
if you need more help pm me and i will walk you through the steps
cant; do itr without adb ??

turn phone off and boot into recovery via home+red key
go to console and type in
# mount -o rw /dev/block/mmcblk0p2 /system/sd
# cd /system/sd
# rm -rf /system/sd/*
# reboot recovery
this has been covered many times in many other threads
NOTE:dont type in the # signs. but do however type in the * sign.
go to recovery console hit enter
parted /dev/block/mmcblk0
print
the fourth line in the 'print' command output shows you the total size of sdcard in MB(or GB if you card is large)..mine says: Disk /dev/block/mmcblk0: 7969MB
use this number(XXXXMB) and do some simple math to get the size of your partitions.
7969MB - 32MB linux-swap = 7937MB
7937MB - 500MB ext2 = 7437MB fat32
32MB seems to be alright size for swap, though it can be lower depending on your sdcard size.
500 MB is a good round number for the ext2 partition...no need for more.
that leaves us with 7437MB for fat32 storage.
Click to expand...
Click to collapse
if you do not want linux-swap then do not figure it in
after figuring out the size of your partitions from using the above method type rm 1 (if you only have one partition skip next part) then rm2
then to make the partitions type (numbers are from above example substitute your own in)
mkpartfs primary fat32 0 7437
mkpartfs primary ext2 7437 7937
mkpartfs primary linux-swap 7937 7969 (only if you want linux-swap)
then type print again to see if it worked. if it did you will have 1 and 2 (and 3 if you want linux-swap) come up under all the other info.
then type quit
then to upgrade to ext3 type upgrade_fs
then if apps2sd is automatic in your rom of choice reflash it and you are set. i am too nice tonight.

too bad its not that simple. i think he means partitioning since he references not having adb to do the partitioning in the guide i linked him to. (sorry for assuming your gender OP)
i just want to format my ext3 app2sd partition....
it already has fat32 , ext 3 , and linus swap
really only want to format ext3 partition so i can install my new rom
just wondering can you format ext3 partition without havn'ing to erase fat32 and linus swap

paragon partition is aprogram that will enable you to partition your card on your computer and format.

THIS IS WHAT YOU NEED TO DO to format ext. the other guy must've confused u
turn phone off and boot into recovery via home+red key
go to console and type in
# mount -o rw /dev/block/mmcblk0p2 /system/sd
# cd /system/sd
# rm -rf /system/sd/*
# reboot recovery
NOTE:dont type in the # signs. just push enter when done typing each line. and be sure to type everything exact and carefully.but do however type in the * sign.
errr wrong post
i am interested in creating a SWAP partition on my sd card to increase rom speed, even tho CMs roms are preety fast already. I hav e 8gb CD with about 500mb ext2. now if i use this method to create Swap partition:
Reboot and enter recovery
Enter console
#parted /dev/block/mmcblk0
#print (to verfiy we know what size card we are dealing with, the details should be straight forward)
rm 1
rm 2
mkpartfs primary fat32 0 7200
mkpartfs primary ext2 7200 7700
mkpartfs primary linux-swap 7700 7732
#print (to verify we have the 3 partitions)
i know how to backup music and everything on fat32 to my PC(to later restore) because doing the above will reformat entire card.
my question is do i need to back up my ext2 with all my apps and data on it, and if so how? or will it do everything itself when i reboot my CM rom? i am trying to create this swap partition without really changing everything and without wiping
There are quite a few threads on this, but granted they aren't that easy to find (I'm looking at you, people who name their threads "PLZ HELPPPPP!!")
boot in to recovery and go to the console:
cd sdcard
mkdir app
mkdir app-private
cp /system/sd/app/* /sdcard/app/
cp /system/sd/app-private/* /sdcard/app-private/
All your apk's are now on your Fat partition, copy those two folders to your computer
after you have remade the partitions go back to the recovery console (don't do this in terminal, but you can use adb shell when the phone is in recovery mode). This time we have to mount your new ext partition as rw.
mount -o rw /dev/block/mmcblk0p2 /system/sd
cd /system/sd
mkdir app
mkdir app-private
cp /sdcard/app/* /system/sd/app/
cp /sdcard/app-private/* /system/sd/app-private/
You're done. expect your phone to take a few minutes to boot up as it re-creates the dalvik-cache.
What's the console command for deleting the contents of the ext partition? (\system\sdcard)
Can you reformat the ext partition from the recovery console?
Thanks
If you want to delete the contents of your /sdcard then in recovery console mount /sdcard then rm /sdcard/* should do it for your fat32. To clear your ext3 do in recovery console mke2fs -j /dev/block/mmcblk0p2
Hey,
I like to mount my external SD Card as ext3 to support large files. The SD Card is formatted with ext3 but now Android shows only an empty folder.
So i tried to remount the SD:
Code:
mount -o rw,remount -t ext3 /dev/block/vold/197:33 /mnt/sdcard/externald_sd
But it doesnt use something... Does anybody has an idea? Some Example or sthing else?

u need a kernel that supports ext3. u can ask one of the guys compiling at the moment if they have time to add an ext3 module for u.
May be a stupid question:
would ext4 work instead? I thought the system partition would use this FS.
filesystem is already ext4

well the system uses ext4 so it should work, but i'm not sure what u're trying to achieve. i use a 16 gb class 10 formatted fat32

He's talking about formatting external sd-card
When I get him right, he has a file that exceeds the 4GB FAT32 limit.
So he looks for an alternative to FAT32, which might be some kind of ext*-FS.
wintel your right!
In the Android-Hilfe Forum someone said the system expect first an vfat partition and then the ext. I think thats wrong cause its not working but somehow it has to go.
Hmm should I write these mount command I postet in the init.rc? Or something else. Would be very nice if you post your ideas!
Thanks
init.rc+ ext3 module/object included in kernel
Hmm okay thats good but how do I use them? So I can read and write to my external sd card with an ext3 or ext2 partition.
Thanks
Come on guys where are the great developers?!
Ok I did a test with busybox inbuilt mount, but I tried only with an image.
Not with a real SD card! This worked for me:
On a linux box:
# dd if=/dev/zero of=/tmp/image bs=1M count=1k
# mkfs.ext4 /tmp/image
Copy file to your phone. Then:
On the phone with terminal:
# mkdir /sdcard/mmnt
# busybox mount -o loop /sdcard/image /sdcard/mmnt
To unmount:
# busybox umount -l /sdcard/mmnt
Anybody tried that?
If I understand u right u puting an image file (ext3/4) on the sd and mount that as a virtual disk. Wouldn't the image file be bound to the same restrictoins as other content on a fat32 file system? Like the 4 gig limit!

using a photon 4g but....
what i did was get an external sdcard reader writer...
(used ubuntu) and let it mount
fdisk device and DELETE ALL PARTITIONS
write
fdisk again
create a linux primary type 83
type mount and grab the /dev/sdcX value (it was /dev/sdc1 for me)
umount that
then
mkfs.ext3 /dev/sdcX ... ( heres the thing though with cyanogen mod 7 kernel 2.6.32.9 SMP PREEMPT)
had to reboot twice for it to be seen in file manager...
its buggy but it does work for the most part
Reviving an old thread, but I just found that I can format a MicroSD under NTFS and it will work with Paragon's NTFS module. At the very least, my phone will mount the drive. I partitioned and formatted it with ext4 on my Linux machine and it didn't recognize it, but I did have it use the GUID partition table. Hoping to be able to load up some videos to take with me.

The problem is with the shell interpreting the special character ":"
To make it work, first create a symlink to the device node:
Code:
ln -s /dev/block/vold/197\:17 /dev/sd2
Then mount it:
Code:
busybox mount /dev/sd2 /mnt/tmp
Code:
sh-4.1# ls -l /dev/sd2
lrwxrwxrwx root root 2013-11-16 14:45 sd2 -> /dev/block/vold/179:17
sh-4.1# mount|grep sd2
/dev/sd2 /mnt/tmp ext4 rw,relatime,user_xattr,acl,barrier=1,data=ordered 0 0

An improvement in technique to mount ext formatted SDcard:
1) be root and open terminal
2) insert the card
3) see the block device and partition names from dmesg
4) mount device to location of choice (create the directory if needed)
Below is an example of an SD card with one ext4 partition on it
Code:
bash-4.1# dmesg | tail | grep mmc
<6>[20230.719541] mmc1: new high speed SDHC card at address 0007
<6>[20230.722803] mmcblk1: mmc1:0007 SD32G 29.3 GiB (ro)

Would this work just the same way with i9000?
After this, no more access to the extSD by the Windows PC but only with Ubuntu, right?

Since it's generic Linux kernel and busybox functionality it should work on any 'droid. The SDcard device name might be different than in the above example - you will see the correct device and partition names after you insert SDcard and run `dmesg | tail` on the tablet or phone.
(of course your device must be rooted and have busybox...)
Typically Windows is engineered not to recognise anything that does not come from Microsoft, so you will not be able to mount the Linux partition via Windows.
