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 :p)

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::eek:

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.

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...

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)

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.
