Hello!
My problem basically is that i can't use Link2sd - i'm currently running the latest CronosX mod - because it can't create the mount scripts. I keep getting the following error:
mount: mounting /dev/block/vold/179:2 on /data/sdext2 failed: device or resource busy
i have a trascend class 10 8gb SD, i have a 6,5 gb Fat partition and the rest is EXT2 (now). I formatted it with minitool partition magic.
I have googled the problem for days now, seems i found nothing useful..
so far i tried:
ext3, ext4 -- then still couldn't create mount scripts, but i also had the following error msg in OR:
"can't mount /dev/block/mmcblk0p2 (invalid argument)"
although in SD utilities when checking the ext partition it recognised as EXT4 or EXT3..
with ext2 it seems working as of i don't see that msg..
still no link2sd. I read in the mod's forum that the app is supported, so it can't be the problem.. or is it?
Same issue, resoved by using FAT32
I had the exact same issue you're having. I tried using EXT2,EXT3, and EXT4 but couldn't get it to work. I finally got it working by using a FAT32 partition.
I know this may sound a bit dumb (like myself in android technicals) but
1. Do you have the specific kernel modules loaded to recognize these filesystems?
2. Are the devices attached to the PC with memory card access? [should not be].
3. Maybe you should try partitioning with a linux distro or some specific tool (might want to check out some instructions.
I am operating Link2SD with a fat16/32 partition (I don't know which )
I have same problem does someone solved it ?
i had no solutions whatsoever.. currently i'm using the mod's built in app2ext
i made an ext2 partition which i transformed into ext3 with openrecovery.. now i have an app folder which is automatically used to store my apps.
no link2sd for me anymore :\
although i have some other issues for i'm about to open a new thread
I found the solution : http://forum.xda-developers.com/showthread.php?t=1713478

Mount as ext4 is not a problem. It should work.
Sent from my XT720 using xda app-developers app
how you can solve this problem, is to make the second partition a active partitons with MiniTool Partition.
When de second disk is a active partition it wil boot before the boot of the system.

you must re-partition your sd card, BUT, just do it for your sd-ext only:
with Partition magic
1. delete your sd-ext partition (JUST YOUR SD-EXT PARTITION)
2. create partition
3. set as Primary
4. and CHOOSE ext4!!,
5. ok and then,
6. Apply
I hope this will help you..:good:

I had the seem problem and I solved creating 3 partitions. The first is not utilized but it must be create because as the Link2Sd as the AndroidOS search the data partition in the second (or last for AndroidOS) partition. I have created the first more small as Linux Swap, the second in ext2 fot Link2SD and the third in Fat32 for SD-Ext Data.
So the App works fine.
Sorry for my English.
Much Appreciated

No apologies necessary, i believe you were clear enough, well what do you know i must say inverting the order does seem to work
1. swap 2. Ext and 3. Fat/ Fat32

if i do that then i cant connect my usb storage to my PC, cuz if you create partitions with minitool, only the first partition is read as usb storage, so if you make the first part e.g. a swap file, then PC wont see your usb storage when plugged in via usb... and in minitool i see all partitions without drive letters, just .* sign after i format and create partitions.... and nothing helped me with mount script error either...

sir tnx for this info... error already resolved... thanks again so much...
Connect Phone to PC in Mass Storage Mode
Open MiniPartition Tool
Format the 2nd Parition as EXT4
Disconnect the Phone
Open Link2SD and you will see acript created and mounted already (for apps in SD card)
easy solution work for me ;D
after create partition ext 3 , just go to root file manager and change system file from read only RO to read write RW and recreate mount script on link2sd . hope it works happy new year!

I had the same problem and had been looking for a solution until I found your help. Just want to thank you for this. It helped a lot! Fixed my problem :good:
Hi, I have a same problem.
But before I repartition the ext2 how can I save the content? My previlus installed apps will not work, I think in this case.
final solution
backup your sdcard and format it
recreat 2nd partition ex4
congratulation :good:
Solved!

Zachary had the solution for me! Just convert link2sd to system app (function of link2sd, after that my phone crashed and restarted) and clear the ext3 or ext4 partition (or reformat). I used Minitool Partition Wizard under windows. Don't forget to select primary partition!
I tried using MiniTool Partition Wizard to format my android sd card, I split the first half to be fat32 and the second half to be ext4, when I do that though the ext4 partition doesn't stay... I even tried twrp to partition it, to no avail it said it wasn't able to create the ext4 partition but the fat32 partition was made successfully.
**NOTE**
Apparently, you need a swap partition to be able to have ext4? Well, I created one and now everything works fine and dandy, before I didn't have one and it worked great...
You dont need swap for ext partitions.. there is no connection between them.
I dont know much about those tools but if you create partition through recovery.. first it makes ext2 partition later you need to upgrade it to ext4.

If I could post link I would, but since I cannot mostly because to the site I'm not a developer (stupid rules) and claims I cannot post anything truly helpful, so as an effect cannot post links to my recovery.
My recovery (ZenGarden 2.0.2.7-T) can create an ext2, ext3 and ext4 partition; the use chooses which format and because of Windows limitations you cannot have more then two partitions on an external drive.
What is the difference between ext2, ext3 , ext4 ?? and what are they actually??
I have 8gb class 4 memory card. If i need to make 3 partitions (sd-ext, sd-data, sd-cache) for installing a rom and a kernel in my pico, how much space should i allot for each partition?

but in recovery mode it is not detecting the sd ext partition if i keep ext4. it is detecting only ext2.. why is it happening like this?

well, make both partitions as ext3 if you want to mount external partition in recovery.
I'm using sd-data as ext3 & sd-cache as ext4 & I can mount it in recovery, nandroid backup also works.

Card doesnt have any problem ext4/ext3 are just partiton type just like fat32/ntfs
Try any other recovery as i have twrp has some issues regarding partitons.

Did you use minitool partition wizard? if that so, you must've made ext partition logical..it should be primary..Or try partitioning using recovery.

which one is better? ext2, ext3, ext4 or FAT32? and using what tools I should partition the sdcard?
I am using cm9.2.2
before that, I partition sdcard with Amonra Recovery with ext2 and use link2sd and have a problem, some times sdcard removed unexpected, when I reboot sdcard is not read, I pull out the sdcard and insert, and sdcard read normally. I reboot and sdcard not read again, I do this many time and finally can read sdcard. but it happens over and over again. I try to format the phone and install app, move app like unrooted phone, the sdcard work fine..when I try use ext2 with link2sd some times its happend again.,
help me..sorry for my bad english, I am Indonesian.
thank you before..
If you want to know what other people use to do this here I come:
How I make the ext partition:
Minitool partition wizard (windows)
Gparted (Linux)
Clockwork 6.0 (only for CM10+)
I didn't have any trouble with that programs, but be careful with the Clockwork because formats ALL the SD card, the ext and the fat partition, so make sure you do a backup of the SD.
Format of the second partition:
Always ext4
Link App
Link2sd is the best, other caused troubles over the time (reboots, not reading the sd, not reading the ext partition, etc)

I used ext4 in all CM from 7 to 11 and no trouble, but always formatting after every wipe with gparted or minitool, because Clockwork 5.0 seem to not format well the ext partition, so after every wipe you should reformat with those programs.
From my experience use ext3, it is good and compatible with everything, allmost

EXT4 has a tendency to corrupt
(At least for me )

Ext4 works great.
(Partition it with AmonRa recovery for a 100% guarantee of success, buggs with clockwork)
