[Q] SD Card will not mount after ext4 part.

Attempting to partition sd card with ext4 -a process I completed multiple times successfully on a Nexus One, the process appeared to complete but now the phone will not mount the sd card. I've tried a wipe/reset, to no avail. I can still access and partition the sd card through adb, but the phone cannot mount it to format/partition, restore from recovery, partition sd-card from within ClockWork Recovery, nothing. I've re-partitioned the sd card through adb, which indicated a successful completion, but the phone still refuses to mount the sd card. If this weren't a Nexus S with it's cursed internal sd-card I would simply swap out the sd card with another or format it externally like all the google topics I pull up on the subject suggest.
Is this fixable or has the fused sd-card scenario become a liability?
Common Error messages:
Can't mount /sdcard
Can't mount /sdcard/.android_secure
Phone: Nexus S (US, T-Mobile, manufactured Dec. '10)
Recovery Img: ClockworkMod Recovery 3.0.2.4
Rom: CM 7.0.3 (now wiped, cannot put back on since sd card won't mount)
fstab:
/dev/block/mtdblock4 /cache yaffs2 rw
/dev/block/platform/s3c-sdhci.0/by-name/userdata /data ext4 rw

/dev/block/platform/s3c-sdhci.0/by-name/media /sdcard vfat rw
Can mount everything except the last one, /sdcard.
I've tried all the recommended procedures garnered from the first 10 or so pages in google, xda, cyanogem forum, etc:
Restore from nandroid: Not possible, can't mount the SD,
Wipe/Reset: can't wipe /media as sd card won't mount,
partition sd card from within Clockwork: indicates success but does nothing,
format from within clockwork: unable to mount,
repartition using adb: works, parted can see them, I can move files to from, but the phone will not mount,
clearing fstab: no effect,
Fastboot works, but I don't have the proper images. ADB works, as do the installed utilities. Have not tried ODIN as again, I don't have the proper images. Should I attempt to compile my own images from source?
Update: SOLVED, Microsoft Windows. To whom it may concern: I was able to mount the /dev/block/platform/s3c-sdhci.0/by-name/media from two different laptops running OSX and Fedora/Ubuntu then successfully been able to partition them with fat32 as the ClockworkMod (and maybe Cyanogen?) expect with 0 progress. Then I pulled out an old Windows machine, installed the JDK/ADK's +tools and performed the same procedure and that time it worked. I'm uncertain as to what particular quality a 'genuine' Windows formatting provides, but either this phone or the particular software combination I'm running require it. I was able to mount & re-partition the /sdcard in Clockwork, then manually remove rebuild them and upgrade to ext4 using tune2fs as usual. In the interim for work and such, I had to find a surrogate (for the SIM) and could only find and old k750i (which still had a full charge and worked flawlessly all day, btw). Wow phones used to be small.
I think I was missing something about the way ClockworkMod handles fstab, because everytime I would modify it specifically to the specs I passed to parted while creating the partitions with mkpartfs, it would either ignore or overwrite them. So be careful messing with the sd-card, the S's aren't like the One's in the sense that if you screw it (the sd-card) up or it goes bad you can't just take it out and format it in another machine/phone, you have to appeal to ClockworkMod. ODIN $ucks by the way, I found fastboot to be much more effective.

If you format the sd partition ext4, then you should change the fstab too.
from
Code:
/dev/block/platform/s3c-sdhci.0/by-name/media /sdcard vfat rw
to from
Code:
/dev/block/platform/s3c-sdhci.0/by-name/media /sdcard ext4 rw
or from
Code:
/dev/block/platform/s3c-sdhci.0/by-name/media /sdcard auto rw
The 2nd last entry there is the file system type.
Likely, this would have solved your problem.
Of course, I don't know, whether the recovery has the vfat type in fstab. You might have to change it there too. On my linux box auto works very well in fstab.
Of course, if you partition your sd partition ext4, you won't be able to use it as usb memory from windows. (At least I am pretty sure you can't, haven't tried)

Well of course I couldn't let it die, I went back and started tinkering again now that I have a way back. I can't change the fstab it seems, whatever I change it to gets over written everytime either Clockwork or the Rom starts. It's weird, I know I'm missing something and I don't know much about CWMod. (had Amon_Ra on the N1, which had the nifty fsupgrade script)

I'm quite familiar with unix style fs and fstab, it's the stubbornness I'm not used to. I'm also spoiled by vi and nano. CW has some nice scripts built in as well though.

[DEV]Dualboot 2013-05-12 - concept for all 2nd-boot roms and new CM10.1 SDCARD rom

After a lot of testing it is time to present "new" way to use dualboot on defy.
How it works.
Stock and custom roms can support different ways to boot a rom. 2nd-init, 2nd-boot and stock.
For dualboot we need 2nd-boot. First we use 2nd-boot to run TWRP recovery from quarx. With TWRP we can mount sdcard as /system.
With a "modded" update script we can install system files to a sdcard partition.
For this you will need 3 primary partitions on your sdcard. First partition fat32, secound partition min. 512 Mb ext3 and 3rd partition min 512 max 2048 Mb. (You can use MiniTool Paritition wizard Home edition http://www.partitionwizard.com/ to create this partitions)
You need to change the /meta-inf/com/google/android/updater-scipt:
NAND
Code:
mount("ext3", "EMMC", "/dev/block/mmcblk1p21", "/system");
ext3 partition, it is the 2nd partition
Code:
mount("ext3", "EMMC", "/dev/block/mmcblk0p2", "/system");
To install the modded zip you have to run the TWRP.
After TWRP boots you can install the "modded" rom zip.
Now we need to install files to boot sdcard rom from your NAND bootmenu.
For this we have to edit the ramdisk from /system/bootmenu/2nd-boot/ramdisk and create a update.zip that install new files to NAND /system.
You have to edit all /system and /data mount points. They have to match with sdcard.
On NAND /system use /dev/block/mmcblk1p21 and /data /dev/block/mmcblk1p25
For SDCARD /system use /dev/block/mmcblk0p2 and /data /dev/block/mmcblk0p3
I use Cygwin (http://www.cygwin.com/) and boottools to edit ramdisk. (sorry can`t remember where i download it)
Now you can boot your rom from sdcard. It is like 2nd-boot.
ROM DEVS can use Aroma Installer to support nand and sdcard install with one zip.
For CM10.1 i edited all files and you can try it.
Check my skydrive folder. /Mobile Phone/CM10.1-2nd-system-for-MS2Ginger
How to install CM10.1 SDCARD if you are running MS2Ginger 5.0
1. install TWRP View attachment 2nd-system-TWRP-NAND.zip
2. set default boot (bootmenu) to 2nd-system
3. reboot --> TWRP should boot now
4. install cm-10.1-20130511-NIGHTLY-mb526-sdcard-gapps.zip
5. reboot to bootmenu and run custom recovery
6. install 2nd-system-boot-cm10.1-2013-05-11.zip
7. reboot and cm10.1 should boot now.
To switch between NAND and SDCARD boot change only default boot in bootmenu.

What sd card are you running this second rom from? class 4 or class 10?

Minimum class 4.

second 10.1 rom from system on sd card running fun!

Any idea how we have to change ramdisk to boot a traditional linux distro from sdcard that works with boot folder instead of the android bootmenu folder?
Just changing hbooot config file to the appropriate kernel and init files?

extracting the ramdisks works fine..., putting them back together seems to go wrong
what command do you use to get them fine again?

use packrmadisk

fstab.qcom modification

I just got my first Android Device (Moto E) and tried to get around the small internal memory by using the sdcard instead of the internal memory for /data. As the KitKat mounting procedure does not seem to be based on vold.fstab anymore, the usual guides to doing that don't apply.
So my idea was to format the sdcard with ext4 and modify the /fstab.qcom file to mount the sdcard as /data instead of the internal data partition. But here's where I don't know how to proceed, as adb shell don't seem to have access to the proper partition during flashboot (though having mounted the rootfs parition which should contain those files?) and is unable to write to the file once the system is running.
I'd appreciate if anyone can point me in the right direction on how to do that.

A little late in the game (I am trying to do the same), but I come across this:
http://forum.xda-developers.com/showthread.php?t=443994
boot partition populates the rootfs. So hack the boot.img (unpack to analyze), and you may find your answer. Hope this helps.
I will give it a shot in the next week.

[Q] Move /data to SD card

I have a Galaxy GIO, which is a fairly old low-end phone. On factory reset, I have about 100MB memory free for apps, and the phone seems to start complaining as soon as I hit the 50MB mark; that's about one or 2 installed applications.
Because I would like to actually be able to, well, use my phone for anything else than calling, I want to move the /data partition to my SD card. I know this'll be slow, but slow still is better than not working at all.
I have done a bit of research, and came around plenty of scripts which claim to mount the second partition of the sd card as /data; none of these scripts work. I have tried 'INT2EXT', 'D2EXT', and I've heard about something called 'A2SD' but I have yet to find a copy of it . To install these scripts I've extracted them, and copied the scripts to '/system/etc/init.d/', after mounting '/system', using ADB.
I for an instant thought maybe my second partition isn't formatted properly, but using adb I am able to successfully mount the ext2 partition as /sd-ext, so I don't see why mounting them as /data should be a problem.
I have also tried to symbollicly link /data to /sd-ext/data and automatically mount my /sd-ext on boot. Obviously this didn't work, because the symbolic link isn't actually saved to disk.
How would I go about moving my data partition to my sd card? I am not affraid of doing some dirty work manually. I am running Cyanogenmod 11.

I will introduce how to COPY(NOT MOVING) /data partition to /sdcard.
1. You should ROOT First.
2. Use Rootexplorer to Copy /data to /sdcard (WARNING:If your sdcard emulated with /data, Data WON'T copy to SDCARD --You need external Sdcard!)
2-1. if you don't want to use RootExplorer, you can use Android Debugging Bridge(adb)
(Youshould download Android sdks from developer.android.com)
--Command : adb shell su -C cp /data /sdcard/data
3. That's all.

Thanks, but that's not entirely what I meant. I can manage to move my data to the SD card no problem, but I want my phone to actually use my second partition on my sd card, as the /data partition.

Oops.. Sorry about that!
First, I am not sure that will work or not, maybe you should try to edit init.*.rc. Which is from boot.mg. I think, maybe mounting sdcard as data is impossible, but you may try editing init.rc(or init.*.rc, * is manufacture). You could unpack your boot img, and you could edit mounting point which is from init.rc!
I hope this thing will help you..

I have looked into init.rc, but that only seemed to create the /data mountpoint, but not actually mount to it. I've no idea how to edit the boot image, or what that even is. Is that the filesystem that is built into the kernel?

Umm.. You should download unpackbootimg or dsixda's Android Kitchen to edit boot.mg. You cannot edit init.rc on Root explore. Use unpack boot.img menu which is from Android Kitchen!

I'll try that out. Still not sure where to look though. As I said, init.rc does not contain any commands mounting /data.

send apps to sd card - avoid low storage advise warning

Hi!
This is a light version from the tutorial described below.
It create a full root WITH option to send your apps to sd card automatically!
How?
Because it create a funtional init.d folder in system/etc where you can put your own scripts to start on boot, giving you full control from your ROM/phone and if you have a ext4 partition in sd card ( 3 GB that's enough ), it will send your apps to sd card releasing storage.
LTE device have a default 2GB /data storage for apps and user definitions, phone call, etc. 3G device is worse!!!
So for a LTE device, 3GB from sd partition + 2GB from data partition = 5GB!
To show you why don´t need more, i have at this momente 61 app in /data/app ( in sd ext4 partition ) that fill 750MB - > 61 apps!!!
If you have a LTE device and your /data partiton is resized you can push a litle the size from external partition to 4GB ( that's enough ), im still trying to find a good size for external partition.
Why don´t need a bigger size?
Because there are file that still inside data partition, in /data/data and dalvik-cache, that still filling up data partition... you can´t take them all ...
3G devices need to be rooted with SuperSu zip first ( i don´t know way ) ... im a LTE user.

Use it only if you need it. Is your option.
I hope this helps you.
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
<<<<<<<The END of low storage>>>>>
I test it in L11 with B370 kit kat factory ROM. From 0.
!!!!Attencion!!!! 3G device users, read pinned post, you need to install SuperSU.zip first than this KingUser.zip to root OR WILL FAIL!!!!
In the step when you will install kinguser.zip change for this one, see the default tutorial here: https://www.facebook.com/groups/huawei.g6.development/permalink/578005512358705/
You need a primary external ext4 partition in sd card with the size you think you need for apps.
To create a primary ext4 partition in sd card with the size you want, you can use mini partition tool (for windows OS ).

Need bootloader Unlocked:

Must have Windows OS to use G6SKnife:
https://www.facebook.com/groups/huawei.g6.development/permalink/577809609044962/
Than i modded this Kinguser flash zip that:
-Roots
-create a working init.d folder where you can store your scripts that will be executed on boot
-it will install busybox apk ( it need it to install some system tools )
- Rashr to change recoverys with the phone ( only need to have the images in sd card )
- It will automatically send all apps to your external ext4 partiton in sd card IF you have one!!!!
How to do it!!!!??????
READ IT CARFULL:
If you already have apps in phone do backup, use the phone default app for that.
Copy this zip to sd card:

Turn off and go to recovery ( TWRP or CWM ) by pressing at same time vol + and power.
Do a factory reset.
Go to install and search the UPDATE-Kinguser-3.4.0-Modded.zip and install it. The phone will reboot.
( A) After settings go to KingUser and open it to check if is ok than go back, open busybox, give root permissions, it will take some time seraching for old files than install it!!!!
( you will need this tools )
Reboot, and is done.
If you start from flash is the same process.
Now your apps go all to sd card.

How is it possible to make the same source folder diferent and multiple target folder mount script?!! I think ther must be an error on this...
The first mount lines are pointing to /data/app and in the other lines pointing again to /data/app-lib?

its possible!

It's possible because works like a symlink. Imagine a room with several doors.
The mmcblk1p2 is the room, the /data/app , /data/app-lib are the doors.

I've instaled the B370 and use Link2SD that have already bought. And it works perfectly and smooth!
With the original ROM / Android it displays a warning that mount must be done after a quick reboot but now everything is working on a normal reboot.
Used KingRoot 3.4.o modified to include /etc/init.d folder creation to Link2SD be able to write mount scripts and with the Huawei B370 cleans everything from Vodafone P that came hacked and pre-installed
Now is better than ever!

Yeah you are maybe right. But when I make it with Link2SD I doesn't find yout tutorial (and even doesn't exists on xda forum) so right now is everything working there no reason to move away from Link2SD

This is how have my phone using a 64 GB SDCARD

Hi!
I buy a 64 GB sd card, create 3 ext4 partitions and mounted like this:
So, now I have 24GB ext4 for data, 10GB ext4 storage and 27GB fat32 for external storage... For mt G6-L11. I had before resized data storage to 4GB.
By default is 2/3 , I can't remember.
