In case this helps anyone, these are the steps I took to check internal storage for errors:
In Android, get the mount points for /data and /system
Code:
$ su
$ grep /data /fstab.qcom
/dev/block/bootdevice/by-name/userdata /data f2fs rw,discard,nosuid,nodev,noatime,nodiratime,inline_xattr,inline_data wait,check,encryptable=/dev/block/bootdevice/by-name/metadata
$ grep /system /fstab.qcom
/dev/block/bootdevice/by-name/system /system ext4 ro,barrier=1 wait
Boot to recovery (TWRP)
Unmount /system, just to be safe
(You can use adb shell or the TWRP terminal)
Code:
umount /system
Check /system for errors using e2fsck (since it's an ext4 filesystem)
(The mount points are a little bit different in TWRP)
Code:
e2fsck -fv /dev/block/platform/soc.0/by-name/system
In TWRP, go to Mount, check System, uncheck everything else
Check /data for errors using fsck.f2fs (since it's an f2fs filesystem)
Code:
fsck.f2fs -f /dev/block/platform/soc.0/by-name/userdata
Reboot
Or, you could just use any old Terminal app, do:
su
touch /forcefsck
... and reboot.

I read that but it didn't work for me. Have you tried it on a Moto G 2015?

I am using cyanogen recovery, but when I wipe to factory reset from the boot, deletes messages, settings but no the applications, so after boot, I have to set it up like new but has icons and even broken icons from old apps unininstalled. Maybe I messed up the recovery, any suggestion to wipe whole thing?
Thanks in advance
To do a complete wipe, you'll need to format the ext partition. Wiping the phone's memory doesn't completely remove everything.
Can I do it from the phone? or do I have to do it on the PC
You can do it from your phone
In recovery, go to the console:
mount -o rw,remount /dev/block/mmcblk0p2 /system/sd
rm -r /system/sd/*
reboot

I noticed that after a wipe, I still had loccy's modified browser. Does wiping only delete information that wasn't part of the original flash?
looks like I dont have mmcblk0p2 in block

Wiping only removes apps and settings (stuff in the /data/ partition of the nand, Launcher.apk resides in the /system/ partition) so launcher will not be affected.
sorry, I cant spot the difference. After I type:
mount -o rw,remount /dev/block/mmcblk0p2 /system/sd
I get
mouting /dev/block/mmcblk0p2 on system/sd failed: Invalid argument
I got it to work by typing:
# mount -o rw /dev/block/mmcblk0p2 /system/sd
# cd /system/sd
# rm -rf /system/sd/*
altough it said that couldnt delete it because it was busy,
I rebooted it, wipe, installed the ROM and all apps were gone
Thanks for your help
One more piece of code to put it on my evernote for later

remount is only used on partitions that are already mounted, and I can't think of a reason why ext3 partition would be mounted in recovery .
after wipe:
Code:
busybox rm -rf /system/sd/*

Wipe clears data and cache only!!!
It does not remove applications in /system/app nor in /system/sd/app
If you have internal apps, ie in /data, then those will disappear
Okay, so I have used four recovery images since I have had my G1 and now the myTouch 3g. Two from Cyanogen when I had my G1. When I rooted my MT3G I had Amon_Ra's 1.2.0G and 1.2.1G. Today I flashed Twisted's Recovery Image. Both Amon's and Twisted's give the option to partition your memory card (Fat32, Ext2, and Linux-Swap). I love that because it makes things so much easier. Well, getting to the point of this thread. Are there any recovery images that format just the ext. part of our memory cards? Is that even possible? I ask because I flash different ROM's every few days and I like to wipe my ext3 to give it a fresh start for each ROM. I know it's just a few codes through ADB, but I'm sure I'm not alone when I say I like to be lazy. That would make things so much easier. Thanks in advance for any feedback.
To wipe your ext3 data ..
Code:
adb remount
adb shell rm -rf /system/sd/*
adb shell rm -rf /data/dalvik-cache/*
This should be the last thing you do before you flash as it will stop stuff from working properly!
In case you need more information: Connect your device and type "adb shell" and then do "mount | grep mmcblk0p2", this will show you where your ext2/3 partition is mounted (mmcblk0 represents your sd card, and p2 is the second partition) :
Code:
# mount | grep mmcblk0p2
mount | grep mmcblk0p2
/dev/block/mmcblk0p2 on /system/sd type ext2 (rw,noatime,nodiratime,errors=conti
nue)
/dev/block/mmcblk0p2 on /data/dalvik-cache type ext2 (rw,noatime,nodiratime,erro
rs=continue)
exit
I found a guide to aply apps to sd on my milestone. I got it working, but the problem is, that apps installed in the data/app-private folder doesn't show as installed. I can see that they are placed in ext2 partion on my sd card along with the other apps, that normaly installes in data/app.Here is the guide i used
After creatting a ext2 partition on my SD card, i copied ext2. To sd card along with
mot_boot_mode script
#!/system/bin/sh
export PATH=/system/bin:$PATH
mot_boot_mode.bin
insmod /data/ext2.ko
mount -t ext2 /dev/block/mmcblk0p2 /data/sdapp
Then in recovery mode i entered
adb shell

insmod /data/ext2.ko
mkdir /data/sdapp
mount -t ext2 /dev/block/mmcblk0p2 /data/sdapp

Do i need to make a symbolic link in data/app-private also?
I would realy like to get this working, because i purchased a lot of apps on the marked. But i have only half of them installed. It used to work on my HTC hero. But it was allready enabled in a custom rom. And that is not possible to do on a Milestone
Thanks
Fixed it by changing app-private folder two
hey glaus...
this almost seems like a guide, hehe...
i'm trying to get apps2sd to work on my milestone as well...
i tried booting in recovery mode and entering the chain of commands you just set out....
but when i go into recovery mode, i see the reboot system option, apply sdcard:update.zip, wipe data/factory reset and wipe cache partition....
and under it, i have e: can't open /cache/recovery/command
any ideas on how to fix this or where can i enter those commands you set out?
i tried in adb shell, but i get a /data/busybox/chown is not found error when setting the permissions...
thanks!
do
crap me too and it deleted some apps 2 i really want this been trying for a week oh i have a telus milestone and get the same above error.busybox is installed and hard drive is partioned
ah crap market is gone 2 lol gotta do a nano restore......man i want this bad i even bricked my phone and brought it back to life this week arghhhh
yeah...i don't know where claus is from...but if he has a telus milestone, he's the only one i've seen been able to install apps2sd with a telus milestone
i've seen other countries, even some with the same bands as we have, but none have had the actual "telus" one....the funny thing is that i can get everything else to work..
i have titanium backup pro, emulator, root explorer and everything is at superuser access...
if claus can help, i will bear his children
edit: how the heck do you install/activate the mot_boot_mode script? I see reference to it in a few wikis on basically that's what will allow us to use apps2sd...but I have no clue how to implement it
got app2sd working on milestone using a diff method will post soon
ok i got app2sd working on my telus milestone here is how i did it if u tried this method here ur gunna have to unroot then root or use a nano backup of freshly rooted phone busybox need mot to be installed so use titanium for back up and proceed http://forum.xda-developers.com/showthread.php?t=692367

I've seen a lot of threads detailing how to create an Ext4 partition using Gparted but if you don't want to download the image and would rather do it all on your phone, here's how:
This entire procedure should take less than 5min so you can go back to messing with your phone in other ways.
REQUIRES:
CLOCKWORK MOD RECOVERY
ADB
FINGERS
I am not responsible for any damage done to your phone doing this process. =.=
1. Download the zip file provided.
2. Extract the zip file to the same folder you have ADB in. (You should now have a folder named ext4 in the same folder you have ADB)
3. Reboot the phone into MAGDLR. Then select the option to boot into the recovery.
4. Make sure that /system/ is mounted using the option to mount partition in Clockwork Recovery.
5. Open a command (cmd) prompt and cd into your folder with ADB.
6. Run these commands in the command prompt. (Commands are in BOLD)
adb push ext4 /system/etc/
adb shell
parted /dev/block/mmcblk0
print (make note of the total size of your partition here)
resize 1 0 xxxx (where xxxx is the size you want for your FAT32 partition. It should equal total size of your partition that you gleaned from print minus 1024 for the ext4 partition you're about to set up)
mkpartfs primary ext2 xxxx yyyy (where xxxx is where your previous partition ended and yyyy is the total size of your sdcard)
.... (Let it do its thing. Shouldn't take more than a minute)
print (Make sure that everything is correct: You have a fat32 partition running from 0 to xxxx and an ext2 partition running from xxxx to the total size of your partition)
quit
Now to utilize the two files we previously pushed to /system/etc/
chmod 777 /system/etc/tune2fs
chmod 777 /system/etc/e2fsck
/system/etc/tune2fs -j /dev/block/mmcblk0p2 <- You now have ext3
/system/etc/tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p2 (Note: CAsE SEnSitiVE)
/system/etc/e2fsck -fpDC0 /dev/block/mmcblk0p2 (Note: CAsE SEnSitiVE) <- You now have ext4
7. You can check that it's truly ext4 by:
parted /dev/block/mmcblk0
print (It should now read that you have a FAT32 and an ext4 partition.)
quit
You're all done! Now you have a 1GB ext4 partition for all your data and apps. If you know what you're doing, these same steps can be modified so that you have two ext4 partitions if you'd like. You can also alter the size of your ext4 partition to something smaller if you don't have that many apps to install or have a smaller SDcard (512MB should be sufficient in most cases, 1GB is slightly overkill IMO)
i will try with my HD2. I need more space to install app on sd not on phone. Thanks so much
Hi, I follow your instruction but when I get a "Permision deined" error when I type in the following commond
/system/etc/tune2fs -j /dev/block/mmcblk0p2
Can you please help?
Many many thanks!!

Crap. I forgot a step. You have to type
chmod 777 /system/etc/tune2fs
chmod 777 /system/etc/e2fsck
prior to using those files. That should fix the permission denied error.
I've edited the OP to reflect the changes, thanks for pointing that out.
Thanks man
Thanks Bro I have successfully make ext4 and I am enjoying my new Rom
Using HTC Desire runnymede 5.0
Amazing. I will keep it for future reference, although I partitioned my SD with CWM recovery and Gparted.
What kind of partition is made when using CWM? I made a 1GB partition on my card that way, and it works great. But I've heard good things about having it as ext4. How does this guide reflect the fact that I already have an SD-EXT on my card that's not necessarily ext4?
Thanks!
please help
please help me i cant get it to work... its same with /system mounted and unmounted...not even one 3rd app is working for me on my win 7 64x when i want to create ext4 this is my last hope. card is brand new 8gb ultra speed its working fine so cant be problem there. it seems like chmod 777 will delete that file..

Hye... I have 2 question...
My phone is a HTC HD2 running an NexusHD2.ICS.CM9.HWA.V2.3 ROM... The cmd prompt cant seem so fine my device. Do have any advice on this???
Secondly, what do i do with the ext4.zip file??? I mean, do it extract it, or put in same folder with ADB??
Btw, i am Super Noob on this, so i apologize if my question offends anyone... 1000 apologizes...
OK, first of all, do you have adb installed correctly? If cmd prompt can't find your device that is the most likely problem.
As for what to do with ext4.zip, you need to extract it to your adb folder.

I have an Atrix on AT&T. Which means there's a bootloader encryption, and the carrier prevents non-market apk installations, which I have resolved since my phone is rooted and I have changed the boot animation already.
In order to do these things, I found Ghost Commander that would let me chmod my system directories...which is fine, but I feel kind of gimped that I can't do it on terminal.
Basically, what I want to be able to do is remount /system as rw using terminal.
This method doesn't work on both terminal and emulator on my phone. I have done:
Terminal:
Code:
sudo su
cd [sdk directory]
./adb devices
./adb shell
su
mount -o remount,rw -t ext3 /dev/block/mmcblk0p12 /system
and this is where I get stuck because I just get an Invalid argument error.
Here is some info about my sytem -
Usage: mount [-r] [-w] [-o options] [-t type] device directory
/dev/block/mmcblk0p12 /system ext3 ro,noatime,nodiratime, data=ordered 0 0
Been searching for the answers for a while now, and now I'm here. What am I doing wrong? Thanks
there
Code:
mount -o remount,rw /dev/mmcblk0p12 /system
back
Code:
mount -o remount,ro /dev/mmcblk0p12 /system
Hmm, well at least I didn't get any errors this time.
I didn't get a confirmation or that it did anything at all. Is that normal?
Run mount with no parameters and look for the line with that device name, should see rw in that line instead of ro.

Thanks guys, but I resorted to busybox chmod command instead lol
I tried this and got no errors, and using cat /proc/mounts/ I see the path as rw. But when I try to copy I still get the read only file system error.
**Lol, I had the phone in usb storage mode and had to switch it to Windows Media Sync**
