Hey all I'm running CMD 7.1 (RC) on a Nexus One and I've followed the instructions to partition my sd card from here as ext3, installed link2sd, and get this error:
Mount script error
Mount script cannot be created.
mount: mounting/dev/block/
vold/179:2 on /data/sdext2
failed: Device or resource busy
Anyone have a solution for this? I have searched XDA and Google for a solution, a few posts showed up with the same problem, but the person that starts the thread with the same problem ends up not following their own thread, or finds a solution without explaining how.
I am having the exact same problem, Nexus One with CM7 nightly 214. Tried S2E but it kept screwing up and trashing my EXT partition so I wanted to try Link2SD.
Finally got it to work but I can only get EXT3 partition, tried updating using Amon-Ra and MiniTool Partition but neither updated to EXT4.
In Terminal you can check the type of EXT partition by typing: mount | grep sd-ext
Everything I tried kept giving me only an EXT2 partition, I tried converting to EXT4 using MiniTool Partition Manager which reported a successful conversion but when I checked in terminal it reported EXT2. I then used Amon-Ra recovery to convert from EXT2 to EXT3 and now Link2SD works. Lexar 32GB Class 10 SD. Hope this helps.
Possible solution
I might have just found a solution.
Do you guys use any kind of bk2sdext? (automated backup of app/data to sdext partition, which comes with some ROMs built in)
To find out, go to your build.prop file in /system and check, it's one of the last lines, if it says something like bkup2sdext.enable=1, then disable it (switch 1 to 0), save and restart.
After that either go to ClockworkMod Recovery or just unmount your SD card, in order to FORMAT the sd-ext partition again so that it doesn't contain any data (and doesn't get automatically filled back, because bkup2sdext is off now).
This way I was able to mount it finally.
I think it has something to do with the build.prop AND the sd-ext partition having some other data on it before first mounting with link2sd.
Cheers.
download titanium backup press menu select batch operation scroll down till u see move all user apps to sd(if supported) and also make sure that you have checked allow application moving(settings->applications)
I have segmentation fault all the time,donnu why
edit: take note, I am not asking on how to backup.
Having 17 thousand messages, don't want to delete any, of them.
I want messages on my inbox but memory consumed is on sdcard.
On The End 4.0 rom
tried
su
mount -o bind /data/data/com.android.providers.telephony /sdcard/data/sms
I think it's not working.
Any help there experts?
If you want to have a backup then use some SMS backup apps. Else, Titanium FTW.
Btw, what you're trying to do is just mounting. You can mount only images or partition storage in linux. Not a DIRECTORY.
Android uses SQLite database to store anything. If you want to have just a backup and you're sure about location of directory. Just pull with ADB, next time when you flash a ROM, you can use `adb remount` and push those database in same location to restore.

Hello, thank you for replying.
I am very well aware on how to backup. What Im asking is to link, having them on my inbox but memory consumed is sdcard instead of internal memory.
On sgs2, I was able to directory bind (by mounting) on gameloft games by mounting from internal memory to external memory.. I just forgot which commands I used.
Oh well, In that case I understood totally different what you were seeking for. Pardon me.
What you're seeking is "Attaching the filesystems" between directories through mount bind. (But there is not -o in modifiers there for creating such).
First backup your /data/data/com.android.providers.telephony safe place, which you won't be touching until Mount Bind process is successfully achieved.
Please consider I'm not responsible if you loose your 17k sms. Install SMS backup etc. But If you carefully follow these steps, I'm pretty sure nothing is serious.
Now,
1) Make directory in your SDCard, say
/sdcard/data/drigz08.telephony.original.source
2) Use app like root explorer to mount or just fire `adb remount` command if you've set up adb in your PC.
3) Move contents of /data/data/com.android.providers.telephony to /sdcard/data/drigz08.telephony.original.source
So now, all of your telephony directories data are moved. Now here comes the best part...
4) Bind those directories...
mount --bind /sdcard/data/drigz08.telephony.original.source /data/data/com.android.providers.telephony
Click to expand...
Click to collapse
step 4 will bind those directories in a way that from any path same contents are accessible, but new data will be store in sdcard only.
5) In case you want to change the path of source, or unbind directory..
mount -o remount,ro /data/data/com.android.providers.telephony

Let me know how it goes.
PS: I tested all of above under standard linux environment. Working fine.

My situation: Galaxy S3 with latest (26 Oct. 2012) update to 4.1.1 via Kies. Then rooted. Works smoothly. External Sd-card visible, no problem.
Then:
repartitioned SD-card with gparted in Fedora machine: mmcblk1p1 with old contents, mmcblk1p2 for new contents, both vfat. Filled mmcblk1p2 with contents from linux machine.
In the phone the first partition (the one with the old data) is recognised as before. The second partition is not seen.
By using the terminal emulator as super user I can mount the second partition by the command:
mount -rw -t vfat /dev/block/mmcblk1p2 <mountpoint>
<mountpoint> is a directory VISIBLE to File Explorer.
After mounting, however, the directory contents are NOT visible in File explorer (even after stopping and restarting File explorer) but can be listed perfectly in the terminal emulator. Giving the cp-command for copying of an individual (MP3) file from the <mountpoint> to the folder Music shows the copied file in that folder and the music can be played in the usual way through the GUI.
Question:
Does anybody have an idea how to make the mounted 2nd partition visible to the apps so that the files can be accessed though the GUI?
Thanks for thinking about this problem.

Found the solution by some more thinking after all:
mount -rw -t vfat -o umask=0000 /dev/block/mmcblk1p2 <mountpoint>
The -o umask=0000 is essential, otherwise the permissions are rwx------; with the umask option they are rwxrwxrwx and thus can be reached.
For safety sake, mount when needed and umount promptly afterwards.

Dear Bananiel,
your post was closest to the solution of my problem, maybe you could suggest something that will finally help me.
I've partitioned external SDcard with CWM to be used for Link2SD. Link2SD's script works fine and the EXT2 partition mounts well. The problem is with the FAT32 partition which can't be mounted by android (I get "SD card empty of file system damaged" in the notification area). When I go in CWM recovery mode I can mount that partition by choosing "mount USB storage" option and then I can see it on my PC. Partition is healthy and PC has no problems with it.
I've tried issuing commands you've suggested in your post through ADB SHELL, after that when I go to folder that I've designated as mount point I can see files from non-working partitio, but the message in notification area still persist. Also the change is not permanent, after reboot I have to do that again.
Thanks in advance for any help given.

In my situation (SD-card with two partitions, both vfat) the first partition automatically was mounted at start-up, the second needed to be mounted manually whenever I wanted to access it. This was also my intention as that second partition contains sensitive information.
Android has a file fstab.<system-id> in the root directory, in which some mounts are mentioned (but not all).
You could try to edit this file with the permanent mounts you are looking for. I'm not sure if that works, however, as I do not want a permanent mount.
Can you publish your results, please?

Finally!
I managed to get my external partitions visible with the help of this post.
Device: Samsung Galaxy Tab2 10.1
ROM: Candy5_p5110 Android 5.1.1
SDExternal: 2 Partitions; 1st VFAT, 2nd Ext3
Using Mount2Sd from Google Playstore.
I had the same mounting issues. SD external would only mount Partition 1 automatically and manually mounting Partition 2 would only be visible via Terminal.
The solution that finally fixed the invisible 2nd Partition was to reformat the 2nd Partition with Ext3 and allowing Mount2Sd to find it and mount to /sd-ext. Formatting to vfat or ext4 did not work. Only Ext3 did the trick.
I hope this helps others and big thanks to the OP for bringing this issue up.
Hey guys, wondering if you could help me. I'm running Jelly Blast V-3.5, with Rafaels Kernel 2.6.35-7 on my S5380i. I've been trying to increase the internal storage on my device by partitioning my 32gb card in CWM with a 1gb ext. I've tried every solution I've found on this forum but I simply cannot get it to mount. Link2sd yields 'invalid argument' no matter where I point it, and when trying to format/mount the ext. in CWM it just says 'apps 2 sd partition not found'.
Here's a list of the things I've tried which have failed to solve this:
Partitioning in minitool, with various sizes and exts, and setting the partition as active.
Flashing conrod script, doesnt seem to be effective.
Script to mount sd-ext at boot, followed iamareebjamal's guide found here http://forum.xda-developers.com/showthread.php?t=1971689
S2E
Mount2SD
I'm completely at a loss, and with the internal storage of the S5380i being what it is, it would be great if anyone could offer me any advice.
Thanks!
do one thing , I'm recovery check if sd-ext is mounted
it used to happen to me that when I flashed new roms I had to mount sd-ext from mounts and storage
so mount it then reboot your phone
go to link2sd and create mount script as ext4
if problem persists , go in storage info of link2sd so see if the partition is mounted
if not you will have to enable auto mount at boot ( if option present in rom ) or mount using terminal emulator

Thanks for responding.
Attempted to mount in CWM but just receive an error. It's as if the partition isn't there at all. Re-partioned the card but still, no luck.
My rom doesn't have the auto mount at boot option, so it looks I'll have to mount with terminal emulator. Could you run me through the process, or point me towards a guide? Cheers
what error did you get in cwm while mounting ?
yry this line in terminal
mount -o rw /dev/block/
mmcblk0p2 /sd-ext
also is mount2sd file present in your /etc /init.d folder ?
Sent from my GT-S5670 using xda premium
The error in CWM when attempting to mount is: 'Error mounting /sd-ext!'
'mount -o rw /dev/block/mmcblk0p2 /sd-ext' in Terminal Emulator yields the following line: 'Usage: mount [-r] [-w] [-o options] [-t type] device directory'
The mount2sd file is not currently present in my init.d folder as I restored my phone from a backup, though when it has been there, the error in CWM is still the same.
The only difference I have noticed is that when partitioning with MiniTool, Link2SD will say that the partition is not mounted, but when partitioning with CWM it will say that the partition is not found.

Did you format ext2 in the secind partition? Normally when you format with cwm, first partition is fat32 and the second partition is ext2. Try to format all available space to 1 partition and using cwm format the card to two part. May be partitioning before makes cwm recognize the wrong part and gives error.

Ensured all the space on card was unallocated and partitioned in CWM recovery.
Attempted to mount /sd-ext again and still receive the following error: 'Error mounting sd-ext!'
Attempted to format /sd-ext and receive the following error: 'No apps2sd partition found. Skipping format of /sd-ext'
Tried so many different ways/combinations of partitions now. Do you think it could be a kernel or rom issue?

Make sure you have backed up all your files in your sdcard they will all be deleted and recreated with two partition.
In CWM enter Advanced --> use Partition SD Card
Set your second (ext2/3/4) partition size then set swap to zero (0).

That unallocated space is your problem. Try to create an ext2/3 partion with mini tool. And if minitool gives error than you probably have a defected sd.
And one more suggestion try the cwm in rafaels kernel thread.

Thanks for taking the time to talk me through this.
Turns out my SD card is defective, swapped for another card and I've now increased my internal storage!
I'll be sending the other one back.
Thank you again for your time :good:

Thanks for the link! seems like my CWM wasn't detecting sd-ext.. this fixed!! feared my sd card was ruined.. really thanks a lot!
Hi,
I have a Samsung Galaxy S3 verizon model. Its rooted and running CleanROM 6.0R2 ROM android 4.1.2.
I am trying to accomplish below
1. Mount external sdcard in read-only mode. This is to avoid files on the extsdcard being accidentally deleted.
I have music and some old photos in there. Sometimes my son plays with the phone. I don't want him
to delete all the photos/music on the external sdcard.
I have tried following, but none of then resolved the issue
1. Partition external sd card as ext3 and set all files/dir to read-only permission from ubuntu box.
This didn't work because, phone doesn't recognize the sdcard and partitions on it.
2. Partition extsdcard as vfat and set permission for the files/dir to read-only using root-explorer.
I cannot set permissions for vfat partition.
3. Partition extsdcard as vfat and Mount extsdcard as read-only using "root-explorer".
Doesn't work. Files can be deleted from other apps like Gallery.
4. Partition extsdcard as vfat and mount extsdcard as read-only using terminal and busybox.
This works. But files are owned by root. For group and other, permission is None. Hence
other apps are not able to view the files. I also cannot chmod and change permissions of the files.
It gives "File system is read-only" error.
From reading many posts, I conclude, partition has to be vfat for apps like Gallery/video player etc to view it.
Only option to achieve read-only on a vfat partition is to mount it read-only. Based on this, any idea how I can achieve my objective?
Also, once set, what happens is the phone is rebooted? Anyway to repeat the sets at boot time?
Thanks
