[Q] Cyanogenmod 7.1 & Link2sd: Oil & Water?

Today I finally updated my Nexus One to CM 7.1 RC1. Everything in the update went fine, phone booted up perfect.
But I'm having some serious issues getting Link2sd to work now. I first tried using a ext2 partition that was already on my sd card from before. Kept getting this error message from link2sd, no matter how many times I rebooted:
Mount script cannot be created.
mount: mounting /dev/block/vold/179:2 on /data/sdext2 failed: device or resource busy
Click to expand...
Click to collapse
I then wiped the ENTIRE SD card, which included destroying the ext2 partition. From my newly blank SD card, I created a 2nd partition using MiniTool Partition Wizard in an ext4 format. Uninstalled Link2SD, reinstalled, opened the app - and I have the exact same error message:
Mount script cannot be created.
mount: mounting /dev/block/vold/179:2 on /data/sdext2 failed: device or resource busy
Click to expand...
Click to collapse
What am I doing wrong here? I've also tried using a FAT32 partition, but using that I got a similar Mount Script cannot be created error except it was an I/O error - whatever that is.
Please, someone, anyone, tell me this can be fixed and it's not an issue with CM7.1RC1.

When you did the wipe did you do it full wipe (erase on)? If not then try that. Also try in an ext3 partition.

Thanks for the suggestions. Unfortunately I have tried both of those to no avail. I always do a full wipe when updating ROMs, so that's never really been the issue. Tried ext3 twice. Both times I got Mount-Script-Creation errors (device or resource busy).

Sorry my bad when I said full wipe I meant for the SD card because it's happened to me once I did a quick wipe and it still didn't work then I did a full wipe and it worked.

What did you do a full wipe with? I'm guessing Amon Ra from your signature?

Actually no I did it from my computer with this http://www.sdcard.org/consumers/formatter_3/ just go into option and put "FULL (Erase)".

Alrighty I'll give it a shot and let ya know. Thanks.
EDIT: Tried...epic fail. Still the same error.

In that casse I'm kind of running out of ideas maybe link2sd isn't compatible with cm7.1-rc1 yet?? If I were you I would try DT, s2e or some other app2ext solution and see if one of those work (DT is usually the one that works the best).

ISSUE RESOLVED.
Sort of.
Did clean wipe of everything (except boot, of course) using Amon Ra.
Downgraded back to CM 7.0.3 (using Amon Ra)
Flashed DTAPPS
a2sd cachesdreset
a2sd install
Installed Link2SD
mount -o /data/sdext2
Set partition type in Link2sd to ext2 (which is very odd considering I know I partitioned a ext3 filesystem in Amon Ra...but whatever)
Reboot
Link2Sd works perfect
Now I gotta figure out how to make DTAPPS go away. I've heard it's counterproductive to have them both on there. We'll see.

Ok that's cool I'm glad you got it resolved and AFAIK it might cause problems but if it works for now why mess with it... Oh right cause it's fun

Figured out a better workaround method. LINK

Will an ext4 partition do as well in this case?

Good question, didn't try it. I used ext3. The original a2ext mod method designed by icecreamisdrugs was meant to be used with an ext3 filesystem, and that's the method that I borrowed for my workaround. I imagine as long as you're using a CM ROM it should work fine. But don't quote me on that.

Can work with Motorola Milestone? Thx... I read the other post that u linked here.
P.D.: ops, I use HO!NO cm7 Gingerbread for Milestone

Cant upgrade cm7 on p990

Im trying to update to a newer nightly build ....
but want to preserve apps, contacts, sms, settings....everything
im using vorkKernel and ext4...
cant i do a strait update....
could i just update individual files?...
i tried titanium backup pro but came out with losts of bugs ....
please help

You can do a straight upgrade, however you will have to flash Vorkernel straight after (or other EXT4 kernel/converter) as CM7 is EXT3 and wont be able to read /data until you do.

how do i do that...
i use the kernel auto updater....

Flash from recovery.

use CWM recovery.. fully wipe cache/ user data/ and dalvik cache..

What? No need to wipe.

Your /system won't be, CM reformats its to EXT3 on install. Run mount in the terminal and see what it says.

It didn't restarted again means there is some problem in installing. Please read this for more info and make sure you get the exact result as mentioned there.
Few things to keep in mind...
1. [format, optional but recommended] and mount sd-ext at boot
run mount | grep sd-ext command in terminal for it.
Make sure you get this result
/dev/block/mmcblk0p2 on /sd-ext type ext3 (rw,noatime,nodiratime,barrier=1,nodelalloc,data=ordered)
If not format or repartition your sd-ext and try again.
2. mount /data and /system on CWM recovery

Well you might not get the same like yagya did : /dev/block/mmcblk0p2 on /sd-ext type ext3 (rw,noatime,nodiratime,barrier=1,nodelalloc,data=ordered) .
The ext3 for you could be a ext4 so don't be afraid or shocked if you get other filesystem

Ok..then I will format my extra partition and try it again..and the ext partition must be formatted in recovery right? Or any specific mthd i should follow to format it...?

But, doesn't CWM recovery creates ext3 partition by default and it doesn't even provides the flexibility to change it to ext4.... unless you manually do it in other partition manger

no need to mount sd-ext, only need to mount system and data when flashing dtapps2sd, and try a2sdgui to confirm the script is working or not.

Ya its working perfectly..don't no why it didn't restart....but when tried a2sd gui and moved the apps worked perfectly...thank you all for responding...

android see its intalled in the phone memory, but technically it resides in your sd-ext.

Ya it can install the apps to sd ext automatically once you install the scripts...download dt a2sd gui from market and select dalvik cache on sd ext..that's it all your apps will be installed on the partition that you have created...

hey guys if you get following error..
"it was necessary to remove it when upgrading to cwm 3.0 gb based recovery,please switch to edify scripting (updater-script and update binary) to create working update zip package.
Installation aborted"...
i think the above error will appear if you are not using right version...
then try to download it from the following link..
http://api.viglink.com/api/click?fo...m/CJJ606UMY2&jsonp=vglnk_jsonp_13183165556861
it will work perfectly(for me it did)..

the new version cannot install in our mini
i got the same error like above
installed the beta04 version only FYI

If you are still having problem with Darktremor A2SD Script and are fed up use this alternative method to move app to sd-ext....

CM7/Zeus v7 alongside any rom with GB bootloader and CM7 alongside v28a

CM7/Zeus v7alongside any rom with GB bootloader and CM7 alongside v28a
Hi!This is my"how to" for installing two roms on one OB.
1.We need to partition sdcard
partition #1 : format it to fat(will be used as sdcard)
partition #2 : format it to ext4(will be used as system of zeus and must be at least 320 MB)
partition #3 : format it to ext4(will be used as data of zeus and must be at least 400 MB)
2.Now if u want:
1.Zeus flash this
2.cm7 flash this
(DO NOT FORGET TO PUT YOUR INTERNAL ROM`S KERNEL TO /sdcard/boot/ and name it nandboot.img!)
3.cm7 alongside v28a flash first this, then flash v28a with SFT, then root your v28a and after that put files from this bin.zip to the /system/bin
3.Now if u want to boot:
1.Zeus type in the terminal
Code:
su
bootzeus
2.cm7 type in the terminal
Code:
su
bootcm7
3.v28c ICS
Code:
su
bootsd
4.your nand rom
Code:
su
bootnand
NOTE:If u change your nand rom first install your new rom and after that copy your new rom's boot.img and put it to /sdcard/boot.img and after that rename it to nandboot.img and after all this install this if your sdrom is cm7 and if Zeus this
Now partition table is:
Code:
Zeus/CM7/v28c ICS
system /dev/block/mmcblk1p2
data /dev/block/mmcblk1p3
CM10
system /dev/block/mmcblk0p8
data /dev/block/mmcblk0p9

Even if it works you'll still be using the same kernel and ramdisk which will only work on ROM very similar to your base.

I had a look. It looks promising. Its quite a cheap trick and should work on our phone.
I am on my phone now so I can't study what he did in detail and I'm not entirely sure how he handles kernel switching (yet).
It's a good find.
EDIT: Nothing to do with kernel root or command line though.

I have repacked zeus rom`s kernel with sd mounts and put the system partition to mmcblk1p1 but it looks like smthing goes wrong(if sdcard is inserted it reboots to recovery in a few seconds but if I remove sd card it stucks at lg logo) and it have created app, data, etc. folders on data (sd) partition

Make so that it only mount the sd partitions if the sd card is present and is made to be bootable.
Reflashing the boot.img isn't a nice way of doing it since bad flash would result in a bootloop. Linux has the ability to reload a kernel without shutting down. I don't know if the kernel that we use can do that maybe it's worth looking into.

What if i will move /system #2 to /data partition and both of the systems will have data partition on sdcard?

Just everyone thats reading this know that it still booting from phone and then reading data from sd. (Not true dualboot yet )
@ sulley
Why not use recovery as the phone boot.img and then normal boot then goes of two sd. CWM sources are available and can be modified so that it works as a boot manager. It will then be actual dual boot because from there you can load kernel from either sd or phone (and unload the recovery kernel and with its dying breath start the new kernel ).A project like this will take A LOT of time and will definitely be more than 6 months. Since it would be based on recovery it should be able to make it work for all phones that can use CWM and have similar boot structure. I will help out on a project like this but I can't be that involved with it since my studies will take up most of my time.

As much I understand, bootloader is needed for dualboot and it applies same on Android. So you got access to our bootloader or just directing the boot.img from 1st ROM to 2nd one? Like handshaking?

Anyway i still want to make one rom at nand and anouther on sdcard, but if i set in kernel system directory to mmcblk1p1(sdcard) it starts to boot but smthing goes wrong but it starts to boot and i know it because it creates app, data, app-private etc. folders on data partition of sdcard(mmcblk1p2), i think this is because it remounts sdcard or smthing like this.Any ideas about soving this problem?

Does anynoe know how to root the P7320 4.04

I use the 3.2 HC method to root my P7320 with ICS4.04 (Hong Kong version), after flash the CWM recovery into the tab I boot into the recovery mode and choose to install the zip file from SDcard, but it said( E: Can't mount /sdcard/ ). I have already copy the superuser.zip into the sdcard's root directory but cannot find it to install, any idea if I have done something wrong?
Many thanks!

Wrong section, anyways try reflashing the recovery, or remount sdcard.
