Just installed link2sd earlier (formatted partition as ext3). Wanted to flash a different rom. Trying to backup my phone, and clockworkmod tells me it can't mount sd-ext. Anyone know a reason and/or work around?
I think CWM works only with ext4 partition AFAIK. So, you can re-partition your sd card to a ext4 partition using CWM, or you can format the ext partition only to ext4 using a computer.

which version of CWM have you got?
3.0.2.4, which I've used for a while now, always tries to back up my 6GB ext2 debian partition unless I remember to change cards first. no way I leave room in the vfat partition to back up that much data.
I'll put it up on 4shared if you want it.

Guess when I get home I'll copy the contents to computer, reformat, and copy back. Hopefully link2sd will notice the formatting has changed and reset itself

Doesn't work with extra either. Version 3.2.0.1 I believe it was.
Guess it doesn't really matter, can just use titanium since its all app stuff on there anyways...

i use CWM to back up my 512MB ext2 partition for my data2ext all the time (with the rest of the backup) and it seems to have no problem, and just to check i just mounted the partition in mounts and storage and it mounts fine. I know some recoveries ive used in the past on other phones would have problems with partitions that were not in 64-128-256-512-1024 MB, etc. format because of block size issue errors that i would get (when mounting or trying to set block size to 4096). I also found that when partitoning/formatting to ext2/3/4 some programs do not properly write the drive formatting and certain systems/recoveries/apps could not properly read them on the android. the best most consistent (android friendly) formats that i have gotten to date were in ubuntu (or any other) linux using "gparted". It seemed to always be the best and usually better than the format done by the phone recovery. Hope this helps. Sorry to drone on and on.
Partitioned originally with gparted. Have since resized to be 2048, and set its label to 'sd-ext'. Now instead of getting an error saying sd-ext might not be supported on my device, it just gives me a generic 'error mounting sd-ext'
I've had ext partition mounting problems before, I'm not sure if the cause is something to do with vold or what, but
after unmounting a sd card to exchange it with another one, it changes the device partitions in /dev/block like
/dev/block/mmcblk1p2
for the sd-ext partition instead of the normal
/dev/block/mmcblk0p2
you can see if this has happened by
Code:
ls /dev/block
in adb shell.
to mount it manually, if the numbering is off,
Code:
mount /dev/block/mmcblk1p2 /sd-ext
I've only had this happen with android running, but it might work in recovery too
Switched over to using data2ext. Mounts the 2nd partition as the /data partition instead of /sd-ext. Can manually mount 2nd as /sd-ext from within rom, but it doesn't carry over to recovery.
A possible solution... Create a symbolic link pointing /sd-ext to the 2nd partition? But then again, since /data now points to 2nd partition, is recovery picking up on that unknowingly and backing up the 2nd's contents when it thinks its backing up the normal /data?
I suppose I should investigate.
Edit: Yep it does backup the 2nd partition, thankfully. Just tried to install a theme made in UOT Kitchen, it borked some stuff, and the restore worked.

Hi.
I've rooted my A70s with chulri's kernel and it seems to work ok.
My next goal is to get more app room ... so I guess I need to resize the app/data partition.
I've thought that having my internal storage formatted on ext4, it would be possible to ln the /data folder to /storage/data without problems, but then I should create a boot script for that. The question is... can I do this with my current root status? What would be the way to do it? I'm don't know enough of linux os to make it on my own.
If the system can't be fooled with a ln, then is there any way to resize the data partition, even if I have to backup/restore my current data?
I don't want to use Urukdroid, since all the versions I tried were very unstable on my machine.
Cheers!!

Follow chulri's method, or repartition your internal storage in Linux, mount it on the archos, and copy the data there. Then edit init.rc and change the data mount line. If it gets mounted in the kernel, you'll have to umount it first to remount it to the other partition.
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)

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!
I really thought this would be stupid simple to do, I needed an ext2 partition for link2sd as well as for a very large file (12GB) as fat32 would not support it. This is fine the file is present and the card partition and formatted in Linux. The primary fat32 partition works great, the problem is I'm looking for a simple way to mount the secondary ext2 partition as read/write somewhere that I can access it when I need, link2sd can mount it but it is not access able to browse it (when I can find it which is not often). I really thought no problem just mount it using mount (worst case), but I ca not even locate the block device to mount, it exists I know that from using a card reader, but I can not get Android (even as root) to list the partition tables (fdisk -l shows nothing). mount shows what is mounted, but not the partition that I want.
All I want to do is auto mount a second partition as /storage/XYZ, I figured 5 minutes or that there would be an app to do this, I have not found any and after wasting to much time trying to get it to work, I'm asking here as I'm lost and tired of fighting for something so simple.
Thanks,
ERIC

Hi there!
I have been using the latest CM11 nightly for a while and decided to go for Link2SD, but I simply cannot mount my sd-ext partition from recovery. I have partitioned my SD-card of size 16GB with MiniTool Partition Wizard, and created an EXT3 partition of size 2GB. The partitions appear perfectly on the software, but whenever I try to mount /sd-ext from recovery, I get an error of "Error mounting /sd-ext!". Could anyone please help me out here? Quite a n00b here about sd-ext really.
I never tried mounting the sd-ext from recovery, but it works just fine after boot. What would you do with mounted sd-ext in recovery?
Well, I want to use Link2SD and have been always receiving an error message while creating the mount script, which goes something like:
"Mount script error
Mount script cannot be created.
mount: Invalid argument"
Also, upon looking into the Storage info, I find that SD Card 2nd Part. is not mounted. This is why I'm trying to mount my sd-ext from the CWM recovery, so that I can eradicate the error. Am I going in the wrong track?
I don't know, ext partition should work out of the box. What I did was partition sd card, boot, install link2sd, create mount script, reboot once again, done.
The only time link2sd won't create mount script for me is when the internal memory is full. Maybe your internal memory is full?
Not really, my internal memory is at least 50% free. Either way, I'll try reflashing the kernel and make a fresh install, and see if the problem persists. Thanks for responding and helping regardless!

u say u created an ext3 partition?? so u must hav selected the same when creating mount scripts in link2sd right?? then it shud work...
it if did not work try with ext4 partition as i am using the same with ext4 partition for a year now...

Reboot then, dude. recreate mount script again, reboot, let see what happen next
Alright, I finally got Link2SD working and apparently, as it turned out, it's more comfortable with ext4 than ext3. Creating a mount script always failed when I tried with ext3, but with ext4, it worked like a charm. Anyway, thanks for all the advice, guys. Gonna tag this as solved right away.
