I haven't find any posts regarding the mounting filesystems in android (excl. posts with int2ext mods).
Does anyone tried to mount filesystems inside the root tree of the system?
What I have in mind is to mount partitions, which are located on sdcard or mount disks shared with my NAS.
I don't want to do it with 3rd apps, but there is no fstab file in the /etc like in any other *unixes, so my first guess was not correct.

[MOD] Swap Internal & External SD [CM9, CM10, and probably more]
Hi folks!
Like many of you I'm sure, I had the problem of running out of space on the internal SD and all the existing tricks seemed to be too much work. So I took mattiadj's script and just made a few changes for the 7.7 on CM9, then CM10. Thanks mattiadj for this one!
I've tested this on the 7.7 but I suspect it will work on all other devices and other ROMs too.
WARNING: I'm just tinkering, I don't have any solid experience with ROMs, and I certainly take no responsibility for any damage or injuries caused by the following instructions! I'm just passing on helpful hints
What does it do?
From what I understand the script remaps the SD directories, swapping the internal with the external.
init.d approach
Androguide.fr has been kind enough to convert the scripts into init.d scripts, check out the scripts here to test them out and let us know how you go!
What do you need?
- The script, either use one that is attached (extsd2internalsd_7.7cm9.txt or extsd2internalsd_7.7cm10.txt), or create your own.
- SManager to run the script.
- A file manager with root access to check the vold folder, the mounting points for the SD cards and to copy the script over.
Any Issues?
Only issue I have seen is sometimes the script is run (via SManager) after apps like swiftkey and so I temporarily get an error notification (language pack not found), but if you wait just a little while, SManager eventually runs the script and everything is back to normal.
What you need to do:
1) Confirm that the storage locations are:
/mnt/sdcard (internel) & /mnt/emmc (external) for CM9,
/storage/sdcard0 (internal) & /storage/sdcard1 (external) for CM10/JB,
/mnt/sdcard/ (internal) & /mnt/sdcard/extStorages/SdCard (external) for XXLQ1.
2) Confirm that the two files in /dev/block/vold are:
179:24 & 179:25 in CM9,
179:8 & 179:9 in in CM10,
179:8 & 179:9 in XXLQ1.
NOTE: If steps 1 or 2 show a different setup, follow the steps described in What I did listed below
3) Download or create appropriate script and copy to /data
4) Open the script using SManager, ENABLE Su, click save then run the script.
NOTE: if there is no output when you run the script then it probably means it was successful.
4)After running the script once, you would have received one error message and if u dont its ok, if u recieve the message then the external SD is unlinked from /mnt/sdcard/extStorages/SdCard, and so the SdCard directory no longer exists.
Create a directory titled SdCard in /mnt/sdcard/extStorages and run the script again.[Only for those who got the message]
5) Check in Settings>Storage to see if the internal and external SDs have been swapped
NOTE: If the result is different for you, follow the steps described in What I did listed below
6) Go back to SManager and enable Su & Boot, then click Save
7) Reboot and check Settings>Storage again!
8) Feel smug about the fact you can install as many games as you want!!!
How it all works:
I picked up mattiadj's script for the S3 from his discussion thread [MOD] ExtSd2InternalSd v3|Increase your data storage|CMW zip|CM10|100% Working| and logically deduced the following format for the script:
mount -t vfat -o umask=0000 [EXTERNAL SD SOURCE LOCATION] [INTERNAL SD DESTINATION LOCATION]
mount -o bind [INTERNAL SD SOURCE LOCATION] [EXTERNAL SD DESTINATION LOCATION]
where:
[EXTERNAL SD SOURCE LOCATION] is the location where external sd can be referenced from. There are typically two files in /dev/block/vold/, one of those files is the external sd source location. For CM9 I set this to /dev/block/vold/179:25. For CM10 I set this to /dev/block/vold/179:9
[INTERNAL SD SOURCE LOCATION] is the location where internal sd can be referenced from. From what I understand, it is always /data/media.
[INTERNAL SD DESTINATION LOCATION] is the location where android will look for the internal sd. In CM9 I set this to /mnt/sdcard. In CM10 I set this to /storage/sdcard0.
[EXTERNAL SD DESTINATION LOCATION] is the location where android will look for the external sd. In CM9 I set this to /mnt/emmc. In CM10 I set this to /storage/sdcard1.
What I did:
1) I checked the storage locations to find that CM9 uses /mnt/sdcard (internel) & /mnt/emmc (external) for sd storage, and CM10/JB uses /storage/sdcard0 (internal) & /storage/sdcard1 (external).
2) Secondly I checked the /dev/block/vold to find two files, in CM9: 179:24 and 179:25, in CM10: 179:8 and 179:9.
3) To work out which vold file is correct I:
a) created a script using the information I found above
b) installed SManager
c) rebooted to ensure previous attempts didn't muck up the results
d) ran the script using SManager
e) checked Settings>Storage to confirm that script did in fact swap internal and external SDs.
After getting the correct vold file I:
4) Copied the script to /data/
5) Open the script in SManager and enabled Su and Boot (execute script on boot with SU permissions)
6) Rebooted and checked Settings>Storage once again.
Final scripts
FYI: The scripts attached contain the following:
===== 7.7 ExtSd2InternalSd for CM9 =======
mount -t vfat -o umask=0000 /dev/block/vold/179:25 /mnt/sdcard
mount -o bind /data/media /mnt/emmc
===== 7.7 ExtSd2InternalSd for CM10 =======
mount -t vfat -o umask=0000 /dev/block/vold/179:9 /storage/sdcard0
mount -o bind /data/media /storage/sdcard1
===== 7.7 ExtSd2InternalSd for rooted stock XXLQ1 version 2 =======
mount -t vfat -o umask=0000 /dev/block/vold/179:9 /mnt/sdcard
mount -o bind /data/media /mnt/sdcard/extStorages/SdCard
Like I said, I'm just a tinkerer, I'll be happy to help but keep in mind my expertise is limited. Let me know how you go!
Enjoy! And don't forget to swap the contents of the internal and external SD directories

What si the difference with link2sd and App2sd and others
Is this script erases all your data in the SD card while doing the process? Or just extend the capacity of the internal memory like a partition to sd card?

no it does not remove your data from sd
Hello,
Sorry, not working like on sgs 3 and galaxy note 10.1. Dont apply now. I m working on a fix with vold.fstab, but format changes with jellybean.
Ported from scripts created originally for Galaxy S 3.
This script swaps internal and external sd storage from init.d.
- You must have a JellyBean Stock or Stock Based ROM
- Must be rooted to flash.
Attached to this post, you will find the CWM flashable zip.
This have zero chance to brick your device, but I cannot say if your SD card doesn't have any issues etc... so don't blame me for data loss or anything.
This script will NOT COPY DATA from your sd, so you will have missing data after you restart the phone.
The data is still on the original internal SD, so you'll have to copy it back to your bigger sdcard's root.
Code:
#!/system/bin/sh
#extsd2internalsd is a modification that allows to switch internal sd to external sd and viceversa. With this you can use default internal sd only for app storage #and the external sd to store all apps resource and all others stuff. The resut is a very big increase of installable apps on gs3
#All credits to Mattiadj of xda forum for the idea and script and to mike1986 for the cmw zip.
#Script Modified for SgNote N7000 by aureusz
sleep 5
busybox mount -o remount,rw /
#Tries to mount as vfat
busybox mount -t vfat -o umask=0000 /dev/block/vold/179:9 /mnt/sdcard
#Tries to mount as exfat
busybox mount -t exfat -o umask=0000 /dev/block/vold/179:9 /mnt/sdcard
#If Sd has been mounted, mount internal SD as extSdCard, if not, do nothing, Android should mount it back as internal.
if busybox mount | busybox grep vold/179:9; then
busybox mount -t vfat -o umask=0000 /dev/block/mmcblk0p11 /mnt/extSdCard
fi
Only problem is, if you use usb mass storage connexion, instead of mtp, it will swap back sd cards.
If you want to remove the script, simply delete the file 11extsd2internalsd from /etc/init.d/ with root explorer or a similar app.
Restart the phone and the problem should disappear.
I'll look into a fix for this.
Strange stuff happenning after first reboot (app2sd make apps disappear). Removing file and placing warning back

Or you can simply switch mount points in vold.fstab

The problem with this method is that, if you remove SDCARD, the phone will not mount internal SD back to it's place.
With this script, the internal SD will remount back to internal sd path.
I'm not sure, but that's how I understood it when I read the thread where they talked about this method.
Correct me if I'm wrong, I pretty much a noob at this.

The solution to that can be decompiling framework-res.apk and editing file storage.xml
Make removable flag true for both storage.
This may or may not work but worth a try.

I'm definitely interested in all options regarding this issue, this has been a big hurdle for me on android with sd card slots, so I took to myself to fix it. I know it's easy to do in ASOP roms but, I missed some S-pen features.
Until now, people used bindings for some directories, for large games data, but this proved not to work for some apps, while this solution works for every app.
Spotify for example lost its synced library, because I think the service would check the synchro of the playlist at device startup, and the folders were not yet mounted... etc.. now, it's flawless.
EDIT : not so flawless, looking into modding fstab as suggested by neobuddy89

Is it possible that you post the vold.fstab where the mount point is switched for internal and external SDcard? Thanks.
Re: [CMW, Init.d Script] Swap IntenalSD<->ExternalSD
any updates here?
Sent from my GT-N7000 using xda premium
I'm attempting to format my external sdcard to ext2, just one single partition (no apps2sd magic).
The reasons are to have the ability to store >4GB files on the card, faster read times, and not needing compatibility with any M$ systems/PCs/Junk, journaling (>ext2) is not needed.
At the moment, I'm running a CM based ROM (cyanfox) and will likely try this out on a moto/stock based ROM after.
Here is my progress so far :
I'm able to mount the SD manually, though with some hoops being involved. The bionic will not mount it automatically, and is constantly telling me that it is unsupported/empty/needs to be formatted in the storage menu, and a permanent notification.
In a terminal shell, I can mount the device (/dev/block/vold/179:97) by specifying the type only as ext4. This is definitely not ideal, but I get errors when the type is specified as ext2 or ext3. (error : mount: Operation not supported on transport endpoint ).
At the moment, I've made an init script to mount the sd at /storage/sdcard1 but this doesn't cause android to think that the actual sd is mounted properly (empty sd notification still exists). Though it is at least mounted.
And I have edited the fstab file at root to change the sd type from vfat to ext2, but this file rewrites itself at boot. Unfortunately I'm not able to set an immutable bit on the file.. (android is not a type writer).
The ext2 filesystem has been checked for errors, does have files written to it, and is able to be read/written to in android after manually mounting it. Android just insists on a fat partition though.
Any help/tips would be appreciated. I'll update this thread in case anyone else would like to apply this as well.
Also, if I'm missing something blatantly obvious, please let me know
Hello folks!
Can someone tell me how to format the Internal SD of this phone?
And, while we're at it, is it possible to format it as ext2 or f2fs?
TIA!
Ookay. I did a lot of research, and to answer my own question:
The Internal SD can NOT be formatted, because it's not a separate device, but merely a directory under /data. /data/media, to be precise. But it can be ERASED/wiped.
Wiping /data now no longer format the /data partition; rather, it simply deletes everything under /data except /data/media.
CWM (or other recovery) should have a separate command to erase/wipe the /data/media directory.
And to find out what filesystems are supported, one should do cat /proc/filesystems
Thanks for reading! I hope this information can be useful to you, too.
forever alone
Link2SD GUIDE
ROOTED DEVICES ONLY
Link2SD is a good solution to save the contents of your internal memory, I know we have a lot but its a good idea in the case of saving more space on your internal memory.
Back up your external sd contents before proceeding!
STEP 1
Install these:
https://play.google.com/store/apps/details?id=stericson.busybox
https://play.google.com/store/apps/details?id=com.sylkat.AParted
https://play.google.com/store/apps/details?id=com.broodplank.initdtoggler
https://play.google.com/store/apps/details?id=jackpal.androidterm
STEP 2
If you've already installed busybox, skip this step.
Install busybox using the busybox installer into /system/xbin
STEP 3
After install, unmount your external sd card from System/Storage/Unmount SD Card
THEN, unmount your external sdcard and sdext2 partition if you have one, from terminal emulator.
Thsi varies from ROM to ROM, I'm on CM11, so I run these commands
Code:
mount -o remount,ro /storage/sdcard1
umount /storage/sdcard1
mount -o remount,ro /data/sdext2
umount /data/sdext2
If you're stock, do this...
Code:
mount -o remount,ro /storage/external_SD
umount /storage/external_SD
mount -o remount,ro /data/sdext2
umount /data/sdext2
Again, rom specific. If you don't have an sdext2 partition, no need for the BOTTOM TWO commands.
STEP 4
Open AParted and resize your external sd card's partition, then make yourself an ext4 formatted sdext partition. Mine is 8 GB in size, since I have a 16 GB card. The journal write takes a long time...usually about a minute and a half. Don't cancel it or you'll end up with a corrupt sd card.
STEP 5
Remount your sd card by your system menu, this is the easy way.
STEP 6
Toogle init.d in Init.d Toggler. Only for stock ROMs without init.d support. Skip this if you've already done init.d or have a ROM that has it baked/enabled.
STEP 7
Install Link2SD and the pro key. The pro key costs money, so if you're poor than I'm sorry. I'm really poor, it's only a few bucks. XD
https://play.google.com/store/apps/details?id=com.buak.Link2SD
https://play.google.com/store/apps/details?id=com.buak.link2sdplus
Run Link2SD after both are installed. If done correctly you'll get a prompt asking you to create your mount scripts, so select ext4 format and confirm, then CANCEL reboot. Go to Link2SD settings and enable Relink Lib files and Relink .dex files at boot. I also make my cache auto-clear every 6 hours or so. Auto link is a really bad idea. Since some system apps break when you link them. Clear the app and dalvik cache. Some of your apps may crash. Recreate your mount scripts again, then REBOOT.
STEP 8
Go into Link2SD and link all your user apps, you can use the filter at the top and serlect "User" to see which ones you installed. DO NOT link anything that modifies your system, since those apps are known to break. For example, voltage control or ROM Manager / ROM Toolbox break when you link them. Since you have the pro version you can link the internal data too!
DO NOT link any system apps. This is a likely known cause for a brick.
DO NOT link CM themes.
DO NOT link launchers.
STEP 9
You have successfully installed Link2SD and have it working! I suggest installing SD booster or making yourself an init.d script to boost your read ahead speed at boot. This helps A LOT with app execution on older sd cards.
I hope this guide helped! Remember, if you fark up you did it to yourself! I'm not responsible.
The L90 D415 is awesome!!!

Partitions with cwm can work too?
I don't use cwm, but TWRP, so wouldn't know.
