[9001]Mounting external SD Card as ext3

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!

YOU WILL LOSE ALL DATA ON YOUR SDCARD IF YOUR FDISK
BACKUP WHATEVER IS ON THERE FIRST!!!
YOU'VE BEEN WARNED
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

success mounting ext formatted SD Card on Android
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)
<6>[20230.728352] mmcblk1: p1
bash-4.1# busybox mount /dev/block/mmcblk1p1 /data/mnt/sdcard2

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.

Linking from /mnt/sdcard to /mnt/sdcard-ext - automatization

Found the solution, it's in the fifth post
Hey, first of all I'm Linux and Android newbie, so sorry if my question reveals it a bit
As my Internal Storage a.k.a. /mnt/sdcard is getting full and I hate to be reminded of it by notification I can't get rid of, I decided to put some effort into moving the largest files to the SD card. I have a 64GB SD an there still are several free gigs So after some googling I found out a way to link it. It works like this:
Code:
mount -o bind /origdir /newdir
where both /origdir and /newdir must exist, in my case as an example:
Code:
mount -o bind /mnt/sdcard-ext/sd/DictionariesNGHS /mnt/sdcard/DictionariesNGHS
where /mnt/sdcard-ext/sd/DictionariesNGHS is the data containing folder and /mnt/sdcard/sd/DictionariesNGHS is an empty folder for linking. It works like a charm, tried with several applications including some off-line navigations. The downside is that such links are forgotten after a reboot.
I didn't find out how to automatize that. I tried putting the line from second code to the end of /system/etc/init.goldfish.sh (I run Eclipse ICS 1.2) and it didn't get linked after a reboot (but works OK after mounting manually in terminal) - I suspect it runs before sdcard-ext is mounted. Any thoughts on how to make it run after reboot? Or maybe of an app that does this for me?
EDIT:
Put my links into /data/data/init.sh
Tried several not working apps:
ScriptMe by gilsken says Script run mount: No such file or directory
Script Manager - SManager by devworm says
Code:
exec sh '/data/data/init.sh'
[email protected]_maserati:/ # exec sh '/data/data/init.sh'
mount: No such file or directory
while interestingly when I write it by myself in its built-in console it works...
App that works: Tasker by Crafty Apps
I can have scripts run on boot and it works, but I can add only one line at time (or at least it's the only option I found) which is still kinda inconvenient plus it runs all the time consuming system resources. I'd like some less robust solution, preferably executed after boot and exiting after mounts proceed. Any ideas?
EDIT 2:
My "workaround" in Tasker: Profiles -> New -> Event -> System -> Device Boot -> OK -> New Task -> OK -> + -> Script -> Run Shell -> Command: /data/data/init.sh -> OK
Surprisingly enough it doesn't even need root permission...
In init.sh I have several lines with different mounts, it all works well. I'm still looking for less robust solution than Tasker is, or maybe a way to kill it after the init.sh is processed?

hey
can you please post the content of youre
Code:
/data/data/init.sh
---------- Post added at 04:35 PM ---------- Previous post was at 03:50 PM ----------
youre problem is, at the runtime form the mount command, the mount is not in youre path.
can you add to you script the command
Code:
env
and post the output?

I tried it with a file containing only this line:
Code:
mount -o bind /mnt/sdcard-ext/sd/DictionariesNGHS /mnt/sdcard/DictionariesNGHS
OK, after running it by SManager it looks like giving errors, but the folder gets mounted.
Also it seems apps get access to /mnt/sdcard faster after reboot then to /data/data (I wonder why...?) so I moved the script there.
Here you have the output with env at the end of init.sh, run by SManager as root (mounted OK):
Code:
exec sh '/mnt/sdcard/init.sh'

So it works after all with the SManager as I intended, I just don't understand why it gives that error when everything actually is OK...
Any ideas on how to make it run automatically after every mount of sdcard-ext instead of on reboot? Because when I connect it to the computer as Mass Storage, the directory mounts disappear and I have to run the script manually...

for the first, replace the mount with this:
Code:
/system/bin/mount -o bind /mnt/sdcard-ext/sd/DictionariesNGHS /mnt/sdcard/DictionariesNGHS

Found out that the "mount: No such file or directory" error was due to typo in folder path
So to wrap it up:
You need to be rooted first.
Create your init.sh script file, works fine when put to /mnt/sdcard/
Example file (also attached so you have a sample in UNIX formatting - don't open with Notepad under Windows, better edit it in your phone):
Code:
# mount -o bind /sourcedir /fakedir - both sourcedir and fakedir MUST exist!
mount -o bind /mnt/sdcard-ext/sd/DictionariesNGHS /mnt/sdcard/DictionariesNGHS
mount -o bind /mnt/sdcard-ext/sd/Android/obb /mnt/sdcard/Android/obb
Note: you should use a UNIX formatting of the file, not Windows (I'm not sure if it's necessary though).
As hinted in the beginning note, sourcedir and fakedir must exist and after successful mount the fakedir folder will appear to have the contents of the sourcedir folder. Any fakedir's contents are ignored ("disappear") after mount and reappear only after it gets unmounted.
It gets automatically unmounted after unmounting of either fakedir's or sourcedir's media (typically when connecting phone to a computer as mass storage) and I haven't found any workaround for running the script after remounting of media... Any suggestions?
Install SManager (free version here).
In SManager navigate to your script file, tap it and select Script/Executable and tap Su and Boot icons (see attached screenshot).
Done, your folders get mounted on reboot

Samba and other linux aspects related to linux servers can sometimes handle the NTFS file system in a weird way, I would suggest taking a look at these two guides for a couple of potential ways to fix your problem:
http://forums.whirlpool.net.au/archive/971582
http://ubuntuforums.org/showpost.php?p=9562968&postcount=3

Make sure you have the package for ntfs installed. I think it should be something like
Code:
sudo apt-get install ntfs-3g
Then try mounting it again using the command "mount" command. If you want it to mount automatically you will have to add it to /etc/fstab
Why are you using ntfs to being with? You should really use ext if possible, stick with Linux file systems and save yourself a headache if you aren't using this HDD with a computer that does support Linux file systems (i.e. Windows).

First of all Thanks both of you and the Reason i Use ntfs is becouse i have a 1TB Usb HDD full whit Data and i dont wanna Delete all that and make it into another Filesystem and i have another Problem you know the linux USB henarki whit sda1/sda2 Etc When i plug in my ntfs drive and my keybord only it says that i have Sda1/sda2/sda3 Bootet but when i drive the same tail command whit a Fat32 Usb stick i only get sda1 any tips on this ? whill try you thing First Thanks a lot :laugh: (edit: i also updated my USBmount i have no idea if this makes any diffrence but i got Dir in /media/ usb/usb1/usb2 Etc... to usb7)

I just ran a similar command to "sudo mount -t ntfs-3g -o uid=pi,gid=pi /dev/sda1 /media/usbhdd/" on my linux desktop without issue. Can you provide the error message you are getting when running this command? Also are you able to run this command without issue?
Code:
sudo mount -t ntfs-3g /dev/sda1 /media/usbhdd/
Perhaps you should verify that /dev/sda1 is in fact the correct hard drive by running:
Code:
sudo fdisk -l | grep NTFS

The ting is that i run a Tail command to se which sda number that Usb Hdd has and i says that is Has 3 sda number (sda1,sda2,sda3) and this makes me Really confused because when i run the same Tail command whit an flash usb stick (fat32) it only says one number (sda1)
gonna try running Arch linux insteed as soon as my new SD card Arrives :good: btw i have mounted an fat32 usb memory stick
and i have downloaded ntfs-3g package and utdated usbmount package

i have fixed it now my Raspberry pi are running Samba Whit my 1TB NTFS Drive
You need to Run Rasbian newest version
now how to
First
Code:
sudo apt-get install usbmount
to get the newest usb mount package
Code:
sudo apt-get install ntfs-3g
to get the ntfs-3g package to mount the disk
to mount
Code:
sudo mount -t ntfs-3g -o uid=pi,gid=pi /dev/path /media/path1/
were path is you fill in were the Disk is often sda1 but can also be sda2.sda3 my Drive was on sda3 becuse of some wierd ****
path1 do you fill in were you wanna mount your drive because of the usbmount package you now got usb,usb1,usb2 up to usb7
so choose any of them than if all works out you have mounted you NTFS drive
to test if it is munted or not
Write
Code:
cd /media/path1
and then type
Code:
dir
and you shoud se some maps if you got any on you Drive before
sorry for my English (i am from sweden and my spelling is genneraly bad in every language)

Happy to hear you figured it out. It is a bit surprising that it is mounting to sda3. In my experience Linux will give each hard drive it's own sdX number (i.e. sda, sdb, sdc, etc) and each partition on a hard drive will have a number associated with it (i.e. sda1, sda2, sda3, etc). Oh well

Yea i was Kind of Confused to about that but now have i made guide how to fix this problem if anybody other than me experience this :laugh:
Also was First Time in Linux
Thanks to My Friends,Teachers And the people of XDA did i fix This Problem

If you've got various sdaX, that means one of two things:
1 - You've got multiple partitions; or
2 - Your partition table is broken.
If your partition table is broken but you can access your data, leave it as it is, and wait for a chance when you can back up that data to another disk to re-write MBR (or GPT, whatever floats your disk).

[Q] [HELP] Swap sdcard with sdcard-ext

I've edited vold.fstab so that sdcard and sdcard-ext are swapped. But this doesn't work on my XT894. Nothing happens in my case.
Then I found this topic.
In short, you run a script containing:
Code:
busybox mount -o remount,rw /
busybox mount -t vfat -o umask=0000 /dev/block/vold/179:97 /mnt/sdcard
busybox mount -t exfat -o umask=0000 /dev/block/vold/179:97 /mnt/sdcard
if busybox mount | busybox grep vold/179:97; then
busybox mount -o bind /data/media /mnt/extSdCard
fi
After running this script the result is that both sdcard and scard-ext are in fact pointing to my external 32GB card. So in a way I'm happy. Now I can install games and all navigational maps without any hassle. But, I would like my internal 8GB of storage back. To do so I take it "something" has to be mounted to /mnt/sdcard-ext.
My Linux/Unix is of n00b quality so here I am asking for help :cyclops:
I've tried adding these two lines:
busybox mount -t vfat -o umask=0000 /dev/block/vold/179:1 /mnt/sdcard-ext
busybox mount -t exfat -o umask=0000 /dev/block/vold/179:1 /mnt/sdcard-ext
Hoping 179:1 pounted to the internal sdcard and /mnt/sdcard-ext would mount it at exactly that. But it didn't work.
Can anyone explain to me what these commands do? Why vfat and exfat? Is this done so that you always mount the correct filesystem? And what about the vold/179:xx? Does anyone know which one points to the internal sdcard on an XT894 running ICS?
Trust me, I've Googled all I can. I have tried several options, multiple scripts, but my lack of Linux/Unix knowledge is killing me.
Edit:
When I connect as USB Mass storage I get my internal 8GB back. It is accessible on the laptop. When I switch back to MTP it shows a different directory (maybe due to vold/179:1 !?). After I re-run the script sdcard is back to my external 32GB. For now this will do.
I will update later. Sygic is downloading 2GB of data. After that I will switch back and forth between USB M / MTP with and without running the script.
Edit 2
After I connect as MTP, Internal Storage seems to be pointing to an unknown space. There is an .android directory which I am unable to find on the phone.
When I switch to USBMS (from MTP) it seems to switch back to the original setup, sdcard 8GB and sdcard-ext 32GB.
When I disconnect the USB cable everything is back to normal. But, all I need to do is re-run the script and sdcard points back to my external SD.

mount second sd card as a directory so car detects music over USB

Hi,
I use my telephone with a second sd card in the car through usb.
Appearently the car only finds and indexes the first sd card.
Is there a way to mount the sceond card as a directory on the first card?
Kind Regards

I found a file vold.fstab in my /etc/system but there's no info regarding the second sd card?
Can I safely edit and how?

In brief
install a app like SSHDroid
on your desktop connect with putty to your phone so hook up your phone with the usb cable
login is or was "root" and password is "admin"
ls /dev/block/vold will give you some figures 179.0 179.2 179.2 179.8 179.9
ls /dev/block/platform will give some folders s3c-sdchi.0 s3c-sdchi.2 s5pc110-onenand
One can chose between several ways how the folders appear on a windows explorer folder
like a USB stick or a mediaplayer
setprop persist.sys.usb.config mtp,adb results in the little walkman icon on your explorer
setprop persist.sys.usb.config mass_storage,adb results in the appearing of a usb stick
mount is also a commando when given alone which will show you everything that is mounted
In the putty window i did a feel free to experiment
setprop persist.sys.usb.config mass_storage,adb
echo /dev/block/vold/179:9 > /sys/devices/platform/s3c-usbgadget/gadget/lun1/file"
This would result in the appearing of a USB stick with name sdcard on your file explorer in windows.
To make this flash persistent
Look if your rom has support for userinit.d or bootcompletehook.sh somewhere in /data
cm 10.1 has support for userinit.d
in /system/etc/init.d I found 2 files 00banner and 90userinit
vi /system/etc/init.d/90userinit is this
#!/system/bin/sh
# call userinit.sh and/or userinit.d/* scripts if present in /data/local
if [ -e /data/local/userinit.sh ];
then
log -p i -t userinit "Executing /data/local/userinit.sh";
logwrapper /system/bin/sh /data/local/userinit.sh;
setprop cm.userinit.active 1;
fi;
if [ -d /data/local/userinit.d ];
then
logwrapper busybox run-parts /data/local/userinit.d;
setprop cm.userinit.active 1;
fi;
now the folder wasn't there so
mkdir /data/local/userinit.d
in this folder make a file.The name isn't important
cd /data/local/userinit.d
vi mountsdcard

make sure you give rights to this file and the folder one can do that with es file explorer or probable
chmod 751 mountsdcard
I think that's it
This will mount your second sdcard (if you have one ) on your windows like a usb stick. It will do this even if your phone isn't completely started up.
You will not have to do a "mount usb" on your phone. If you do this anyway your first card is also mounted.
This is a neat trick to make your CAR find your music on your phone. If your car has a usb port and the functionality to play music from usb sticks.

I tried doing the same by bind-mounting the external_sd on a folder on the internal_sd:
Code:
mount -o bind /storage/sdcard1 /storage/sdcard0/external_sd/
In the terminal it worked like a charm, but i couldn't get it to work at boot. Have you any other ideas?

Wouldn't it be easier to just mount the ext SD to a folder on the internal SD? This seems like 100 times the work really needed.
I can't recall atm how mounting of SD cards works, but if I had this problem I'd probably just put the songs in a .img file and mount that with
mount -o loop -t auto /storage/sdcard1/music.img /storage/sdcard2/music/

Yeah thats kinda what i thought of. But my init script is not getting executed or at least there is no effect of it.

I assume you've tested it with terminal output, what doesn't work about it? :/

I don't know what you mean, to be honest. I know that init.d should write the logs somewhere but couldn't find out where they are written to.
Edit: when i try to execute the command above it works, but it doesn't work with init.d

Well, for what it's worth you can use CM File Manager to add a shortcut on your home screen if you're on a ROM with Trebuchet Launcher, do that with the executable file and you can at least launch it easily when needed...
With pretty much any other launcher custom shortcuts are supported as is, Trebuchet for some reason lacks it.
(I loathe init.d)

I have now made a script in rom toolbox which does the job, but i'm not very happy with this. I'd prefer doing this simple bind-mount with init.d
@Forssound: Your solution seems to me a bit complicated, just for this simple task.
