[MOD] data and dalvik to SD (ext partition)

OK, I'm going to stop polluting other threads with my stuff.
This should help make sure I can keep up on the discussions and provide support for people trying to use my ZIPs and/or scripts.
NOTE: This version requires JACs kernel and init.d mods. Flash his stuff, then flash mine. All this will be integrated at some point and any other dev is welcome to integrate my stuff with theirs.
In addition to the JAC kernel, you need an ext partition on the EXTERNAL SD card. DO NOT USE ROM MANAGER TO PARTITION. You will get into a boot loop and will have to Odin back to stock. For partitioning, you may use "adb shell" in clockwork recovery, an old G1/Mytouch with Amon-Ra/Clockwork, a computer with a card reader and GPartd, Paragon, etc.. If you do it with fdisk, don't forget to format the partitions, here are some sample commands.
This will format an ext2 partition.
Code:
/system/bin/mke2fs /dev/block/mmcblk1p2
Convert from ext2 to ext3
Code:
/system/bin/tune2fs -j /dev/block/mmcblk1p2
Convert ext3 to ext4
Code:
/system/bin/tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk1p2
fsck, any ext version. Do this when you are done converting between types.
Code:
/system/bin/e2fsck -fpDC0 /dev/block/mmcblk1p2
For all of the above, make sure the partition isn't mounted with "mount". You also have to have already flashed either this ZIP, or my e2fsprogs-ext4 ZIP for the files to be installed in /system/bin.
This version will clean up older versions that I know about. It will remove any use of the playlogos hack, and the older version of my script that JAC included in his kernel.
Quadrant - 1722. I have also not seen any lag from this change. I've tried some apps that make heavy use of the database, and so far it's performing quite well. If you do see problems, I suggest fsck on the ext partition, and perhaps formatting it, to ensure it's nice and clean.
Please note that benchmark results will vary based on a large number of factors beyond my control. Try with a clean phone, no background apps. A faster SD card will help as well. I am using an older Transcend 8GB Class 6 that I used to use on my G1. It doesn't help that the free Quadrant tests lots of stuff, not just activity on /data/data and such.
To see if it's working, open a shell and type "mount". You should see entries like this:
Code:
/dev/block/mmcblk1p2 on /sd-ext type ext4 (rw,noatime,nodiratime,barrier=1,data=ordered)
/dev/block/mmcblk1p2 on /data/dalvik-cache type ext4 (rw,noatime,nodiratime,barrier=1,data=ordered)
/dev/block/mmcblk1p2 on /data/data type ext4 (rw,noatime,nodiratime,barrier=1,data=ordered)
Added data-only ZIP and the disable/revert ZIP.
Added auto-partition ZIP to create 1GB ext3 partition automatically. Note that this will delete ALL SD contents.
Added old-style enable-dc2sd for users of the auto-partition script. Do not use for JAC kernels, use the current dc2sd instead.
Changelog:
8/9/2010: Added loopback style version, should find prior versions and remove them, copying your data from the /sd-ext partition.
v2.
Compatibility fix for JAC -6 kernel.
v1.
Added e2fsprogs w/ext4 support to the ZIP
Better integration with init.d layout
On boot fsck to ensure that the ext partition is kept clean
Automatically copy files if /data has larger directories than /sd-ext

Test versions that should fix busybox to work with the newer JAC kernels. -loop uses the loopback filesystem method (RyanZA style). The other one is for an ext partition on the external SD card.

Feel free to post direct links or links to the kernel thread.

For some reason, the convetr to ext4 command isnt working for me.
Just says "Tune2fs 1.41.6" then back at # prompt
GREAT RESOURCE - Deserves a sticky just for the conversion syntax
EDIT: Maybe not, it said mounted as an ext3 before, now it says ext4
EDIT2: SUCCESS!!!!! EXT4 gives a major boost to the Quadrant score - 1531. WAY better than the~1100 i was getting before. Stupid G1 didnt actually convert ext3 to ext4, even though it said it did. Thanks!

Not that I'm stressin over Quadrant scores, but I just dropped ~100 (previous was 1497) after flashing this. Ah well.

Hmmm, before applying this script, I was just using JAC's v5 kernel, which worked fine, but after applying the OP's script, I cant backup in Clockwork (again lol).
It doesnt seem to mount /data and /datadata, as it only backs up /system and errors out on the other two. Any idea why?
EDIT: The error is really random, Ive now had 2 successful backups, 2-3 that failed due to mount issues, and 2-3 that failed due to MD5 issues. I would like to narrow down the possibilities, and I attempted a restore to stock, rooted, and then used JAC's kernel, same issue occurs (did not use your newest script). That being said, I dont think its your script. (stumped)

When converting to ext4 it said "please run e2fsck on the filesystem"
EDIT: Ran "mount" and it shows same messages you do. So it worked

It's supposed to say that. Do it.
Glad it's working for some of you. As for nandroid, no idea. I'll install jac latest and check it out. Can't think of much I could have done to it though, I can't mod the ramdisk this way.

+1 on the nandroid, I went back and tried and couldnt. Also, tried to flash anamolous deodexed ROM and wouldnt. Gave errors e: cant mount /dev/block etc and failed. Could this be related?

I doubt it, my stuff doesn't run in recovery, at least I don't think it will. I've never seen it run. I'll look into it, but it sounds like the jac mod might have an issue with nandroid right now.
There was a similar issue on the g1 with cm6. I wonder if that fix will work here...

Could you also post the Just DATA, and revert scripts in this thread please
Also, what would be the proper flashing order for just data?
1. JAC init.d
2. reverse
3. Just data
Or do I have to flash init.d, apply kernel, then reboot and flash reverse then just data?

Added revert and data-only to the OP.
If you don't have any sd-ext hack installed right now:
1. JAC init.d
2. data-only ZIP
3. reboot to download mode and flash the JAC kernel
If you already have dc2sd installed:
1. Revert ZIP
2. JAC init.d ZIP
3. Data-only ZIP
4. reboot to download mode and flash the JAC kernel
If you already have the kernel and the JAC init.d:
1. Revert ZIP
2. Data-only ZIP

I am trying to revert this fix, so I can try the new hack involving a virtual EXT2 partition. I tried the revert, and I manually deleted the a2sd and dc2sd files in init.d, but it rebuilds data when I reboot. ANy ideas?

You likely have a script in /system/etc/init.d doing it, or you didn't clean the old playlogos stuff up.
FWIW, I'm working on a similar way of doing it, but with ext4 and a proper init script. I don't like using ext2 for this stuff, too easy to corrupt it.

Does your new loop script require an sdcard with ext 4 partition or does it use the internal sd card?

Thanks for your work! I found your dc2-loop-v1 script. Will play w/ that until you come out w/ something better. Is EXT2 really that fragile in terms of corruption when it is virtualized within a journaled file system (which I believe RFS is)

This loop version doesn't use an ext partition. Just the loopback mount. It will copy the files from an ext partition if you have applied that hack.

Most file system journals don't help with the data just the structure. Rfs rides on vfat, so I doubt it's worth much that way.

Gave the dc2-loop script a shot, to convert from the /SD-EXT method to this new ext4 container method. It creates the container correctly, but never seems to copy everything over. All my apps act as if i've never started them up, so Data isnt getting copied over correctly.
EDIT: Tried again, the dc2-loop script def doesnt work, and I have no idea why. It looks perfect (code-wise), but for whatever reason doesnt end up working properly

can't get your loop script working. every other one i have been able to run flawlessly. i just flashed the oc kernel by jac. any further instructions or pre reqs?

[Q] Bricked, and Odin doesn't fix it

I updated my phone to Cognition 2.1.2, and think i bricked it. I was on Cognition 2.1.1, i disabled the lag fix as per the instructions, and then installed cognition 2.1.2 with Rom manager. when my phone rebooted it seemed to work fine. Then i realized that there was no calculator app installed anymore. I went into the settings screen, but when i clicked on any of the options it would highlight, but not do anything. I rebooted, but i got stuck on an ATT boot loop.
I then pulled the battery, got into the download mode with the button combo, and did an odin oneclick back to stock. however, when it rebooted it went into the stock recovery console and gave an error message "cant mount \dev\block\ stl11"
After that i tried updating with odin 3 to JH2. Everything went ok, but when it reboots it still goes to recovery, but this time it gives me a differnet error
Code:
format_vfat_device -> argv[4] : android
format_vfat_device -> argv[5] : /dev/block/mmcblk0p1
run_program: child exited with status 1
E: Can't mount /dev/block/mmcblk0p1
(No such File or Directory)
E:copy_dbdata_media:Can't mount SDCARD:copy default media content failed.
I can boot into download and recovery with the button combos
I can use adb when in recovery , I'm not sure what to do though (I can't mount with shell, nor can i get to su
I can't get to ClockWork Mod Recovery as it was'nt the last update.zip, and when i try to reinstall packages it says
Code:
E:can't mount SDCARD:update.zip
Installation aborted.
I'm pretty sure this has to do with the lag fix. I think that odin can't wipe the ext4 partition even though i disabled the lag fix.
Please help, am i completely bricked? If so should i return to att even though its been rooted? I guess i could say it was from the OTA.

I would suggest making sure that you disable the lagfix by
Code:
adb shell
touch /sdcard/voodoo/disable-lagfix
Reboot, and it will probably say "converting back to rsf blah blah blah" It takes like friggin 10 minutes to disable
Then I would try to replace the update.zip with the clockwork recovery update.zip. I uploaded it here: http://dl.dropbox.com/u/115587/update.zip To do this I would use
Code:
adb push [local path to update.zip] /sdcard/update.zip
In my case since I'm using a mac (I put it in my downloads folder) I did
Code:
adb push ~/Downloads/update.zip /sdcard/update.zip
Then try to go into recovery mode and reinstall packages, hopefully clockwork will come up and you can restore a good version of your phone
Hope it helps

Laundry? Do you have insurance on it?
Sent from my 42 node TI 89 cluster

i dont know a whole lot about adb or even know if this is possible, but is there a way to reformat the internal sd card in adb like there is in the stock settings menu? if you reformat that should get rid of all traces of anything including lagfixes correct?

I am unable to use the touch command because it can't mount the Internal SD. it gives me
Code:
touch not found
even when i touch files that i now were there.
I wonder if i could flash the voodoo kernal back on to it if it would take care of it. is there a .tar of it that can be flashed with odin 3?
Is there a way to see what partitions are on the internal sd, and like di11igaf said, is there a way to reformat with adb?
Also i don't think warranty covers putting it through the laundry and w/ insurance it costs like $125 to replace

Wow this one is a bit of a headscratcher.
Have you tried manually flashing in a voodoo compliant kernel just to see if it will boot? It's not mounting the internalSD, which is bizarre, but I do know that stock kernels can't read EXT4 data- now I don't know why your internalSD might get switched over, and I have very little expectation that this will work, but at this point what's the harm?

I thought of manually flashing in a voodoo kernal, but the only ones I can find are update.zip or with clockwork mod methods neither of which i can get to. Is there a voodoo kernal that can be flashed with odin3?
Edit: I just flashed unhelpfuls kernal and i am now getting a different error message
Code:
E:Can't mount /dev/block/stl11
(Invalid argument)

I have flashed a voodoo kernel but it just tries to create the ext4 partition, fails and reboots. The problem is that there is now no /dev/block/mmcblk0p1 or /dev/block/mmcblk0p2. There is still a /dev/block/mmcblk0 but since we both tried to flash stock with Odin we no longer have root to attempt recreating the partitions. We also can't flash anything from recovery since there is no /sdcard.
We need a rooted ROM that is flashable with Odin. The e3 recovery also has an option to reformat the internal sdcard but I've only found it with i9000 ROMS where the captivate power button doesn't work to select it.

This may sound crazy, but do you happen to have the update.zip from ROM Manager on the root of your sdcard? From the sounds of it, once you switch back to the voodoo kernel your phone is able to mount your SD again, now it's just encountering errors on your NAND. If you can get into clockwork recovery go in there and have it format your SDCard, once you've done that, try to flash back with Odin one click and see if everything starts working again.

that wont work, I have been messing with this all morning. The op has a corrupted internal SD card. Nothing will fix this because it wont mount. Its just like any other sd card that gets corrupted.
I even went as fas as flashing eugene's froyo that dont brick from the vibrant forums. thats the only 2.2 rom that will partition the internal sd. but a corrupted sd is a whole other ballgame. Just get another phone.

You did catch the part where after flashing the voodoo compliant kernel he's no longer getting the error where he can't mount the internalSD, and is instead getting a message about a partition on the NAND not initiating? The theory here is that perhaps SOMEHOW the internalSD has got some EXT4 data on it that the stock kernel can't understand, so it refuses to mount it, the voodoo enabled kernel DOES understand it, and as such will mount it. The objective is to get that internalSD formatted again so that he can switch back to a stock kernel and have it recognized
I'd also like to add that eugene's kernel also doesn't read ext4 =P Noticing a pattern here?

Another thing that might be worth trying... though doubtful. Do an Odin 1 click, yank the battery as soon as it completes before it gets a chance to boot again. Restart Odin and get your phone back into download mode, and flash in the Voodoo kernel, see what errors it spits out on first boot (if any)

No worries bro, was just trying to help. You probably have more exp when It comes to this, I was just letting the OP know what worked for me in the same situation. Seems like the captivate is a little different beast.
for the record I wasnt talking about flashing another kernal. I was talking about flashing a 2.2 rom ( which thru odin) repartitions the internal sd to stock, which will cut out the ext 4 lag fix issue. It did for me anyway.
With the cant mount issues, I think its currupted. ATT gave my friend another phone with next day shipping. they also said that phones are soft bricking like crazy because of the ota update. so I dont think the OP will have much of a issue saying it was the ota update and getting another phone.

Sorry I didn't mean to come off harsh My theory here is that SOMEHOW voodoo is writing EXT4 data to the internalSD outside of the NAND area and in some cases it's corrupting it in such a way that the internalSD cannot be read by the stock kernel (since it has no EXT4 support) so in theory if you can get the internalSD mounted again it can be reformatted to allow a stock kernel to return to use... if this is the case, or at least close enough to what's happening it would fully explain why the froyo kernel with repartition couldn't touch the internalSD (It couldnt mount or read it due to the limitations for file systems in a stock kernel)

Looks like the sdcard on mine has had it. I got root and ffdisk and parted still give I/O errors when trying to read or write to /dev/block/mmcblk0.

Is this after using a Voodoo kernel? And are you attempting to perform the ffdisk and parted commands while using a voodoo kernel, or stock? I'm just trying to gather as much information as possible on this problem, so forgive all the questions

I'm about to try parted with a voodoo compliant kernal (unhelpful's) But for some reason adb isn't finding my phone when its in recovery. Does this have something to do with the unhelpfuls kernal, or should i just uninstall and reinstall the drivers a few more times?

Nah, make sure you have the phone plugged in when you turn it on and go into recovery. For some reason plugging it in when it's already in recovery doesn't work. At least it doesn't for me...

Ok, i tried that, but its still not connecting. Tried multiple usb ports, and uninstalled/reinstalled drivers. If i put it in download mode it gets recognized instantly.

[Q] Muppet in need of Help

Hi,
I've been a right royal idiot and have spent 2 days trying to get my SGS back into working order.
Flashed Bionix v1.7 Rom (didnt realise it was Vibrant), worked great with the exception that the headset socket logic to be back to front. No audio from external speaker, if you plug in headset you could then external speaker started to work.
I therefore flashed back my origonal ROM with ODIN but on reboot the update failed with can't mount /dev/block/mmcblk0p2 on /data (Invalid argument). After then reading the notes (Yep noob mistake) I realised I should have removed the voodoo lagfix the Bionix ROM had before flashing a new rom.
Having done some investigation it looks like mmcblk0p2 is an j4fs filesystem but nothing I seem to do seems able to change that. Tried to mkfs and ext2 filesystem on it but it seems to be working then aborts saying it wasnt cleanly unmounted and to e2fsck the partition, which I try and it errors with unable to set superblocks on /dev/block/mmcblk0p2.
Any and all help greatly appreciated

JM8 will restore the things your missing

I have tried that, Odin runs through with no issues, but on device reboot it errors with the same. I can boot into clockwork recovery and adb shell. Its really weird, I've done a complete dd dev/zero over that partion. I've mounted it in windows and formatted via that and yet when I reboot and look at the partition via windows, all the data is there. There were a couple of other partions that were j4fs (/datadata) if i wipe that partion using fat.format, when i remount it it mounts as rfs instead of j4fs (great), but when I do the same with /data (mmcblk0p2) it says success on format but when I mount, it still mounts as j4fs...any other ideas?

Just tried this and error is back to origonal ie cant mount /dev/block/mmcblk0p2.

You didn't accidentally store those files on your Sim or SD card right?
(I know, beginners question but just to be sure )
So you can't use your phone at all atm? Just stuck at recovery screen?

I had this same problem last night in the end used odin 1.7. With older firmware and pit (512) files doing a full repartition and reflash with csc. And modem files this was a jp4 set i believe.
This would not then upgrade in kies so i flashed a jpy firmware over the top just the firmware file this time. Not sure but i think i could have skipped this stage and restored from the clockmod backup. Can anyone confirm?
Then i rooted the phone again then flashed a kernel with clockwork mod support and was able to go to recovery mode and restore with the back up i made before i started messing about, though i suspect a titanium backup or similar would have worked just as well.
Hope this helps you at one point last night all I had was an icon with the phone and a computer thought I had really bricked it this time but given what I've done over the last couple of weeks i am not sure that's even possible.

Just tried with Odin 1.7, the JP4 romset still the same error on mmcblk0p2.
Just for avoidance of doubt in case I'm not doing this correctly,
In Odin I have Re-Partition, Auto_reboot, and F.Reset Time checked, Dump, Phone EFS and Phone Bootuploader Update are not checked. I'm using s1_odin_20100512.pit, and have tried Various European Roms including all the ones mentioned so far.
Fundamentally is the problem not that the filesystem type of the internal SD partition is j4fs? It seems the kernels dont know how to mount this type of filesystem, and for some reason I seem unable to change this. I cant even delete/format the data in these partitions.
cronoz, I believe mmcblk0 is the internal SD memory, which has 2 partitions. The first is a 2Gb Fat partition and the second is a 5Gb ext4(j4fs) partition.

A *512.pit mine came with odin the main firmware in the pda box the modem file in the phone box and the csc file in the csc box once i had that mine refreshed just fine. If you have the right combination of those then I'm not sure what else you can do tbh

Thread hardcore speedmod kernel.
Choose first download speedmod....
500.zip
Unzip and flash with odin.
You do have 3 button combo right!

Well this thas put me a lot further forward thats for sure. So i Flashed speedmod-kernel-k13a-500hz.tar. This now bootsl the SGS. It complains bitterly, force closing just about everything, but it does boot. Just about all apps force close, but I can set debugging mode and get in via adb (although the roms not rooted (JP4) :-S).
I can boot into recovery and choose the speedmod Lagfix option. It correctly identifies that /data is ext4. I disable lagfix and the new config is set to convert data to rfs on next reboot. I reboot and it goes through the conversion, backup of /data /datadb and /cache, it then generates md5 checksum and the aborts saying there is not enough space on internal SD. Not sure how to fix this part. When I enable debug mode I can see 2 partitions in windows a 1.8Gb and 5.3Gb, Both are empty apart from my update.zip in the 5.3Gb partition.
EDIT: Also tried the Yes, with factory reset without backup option, this seems to work but on reboot /data is still ext4 :-S
Any other ideas how to proceed now?
Any Full Roms with the speedmod kernel you could recommend?

you can try darky's resurrection rom which is a complete rom with pit file 502
http://forum.xda-developers.com/showthread.php?t=940671
If that fails you can also try to flash jpy or js3 with the 802 pitfile
hmm i think the 2 partitions are the main problem....... It's kind off strange that you only can see the update.zip. How did you create the 2 partition???

Ive been trying darkys res rom, the only problem I think though is that it does say that lagfix has to be removed (ie not ext4 partitions) before installing, and that I suppose is the underlying problem of why I cant get it to work.
I just realised it wasnt 2 partitions, its the Internal and external SD cards, the 1.8Gb seemed to be corrupt, I managed to format it via the SGS menu and it shows the correct 8Gb now.s
EDIT: Hmmm just noticed something, its seems that although it appears I can delete and add files to my internal SD card via windows, it doesnt actually do anything on the card. This very strange :-S

[Q] What folders does Voodoo lagfix actually convert to EXT4?

I was just wondering about the folders that the voodoo lagfix actually changes to EXT4? As in my other thread(s), I bricked my phone by installing 2.2.1 over 2.2.1 + lag fix (without uninstalling voodoo), and fixed it by going to JM8 + 512 PIT repartition then back to JPY without repartition.
Basically I know the repartition option in ODIN converts SPECIFIC folders back to RFS within the system partition (the ~2gb section in the internal SD). In this way I'm assuming that Voodoo applies the ext4 file system to these same folders, does it not?
While the phone is working now, I want to positively make sure that there isn't some random unused EXT4 portion in my phone waiting to rear its ugly head with random bricks and bugs. In my mind this could occur because voodoo and ODIN don't format the same folders, and there could be some sort of overlap happening. Is there a valid method to my madness?
I might get on the voodoo IRC later and ask for help there, or if someone could get hold of curio/know the answer themselves it would be even better!
Thanks for any replies!

data
cache
dbdata

Thanks
I'm assuming odin repartitions these sections then (obviously because my phone is working now) + another section , right?
I saw a thread with the folders that ODIN repartitions but can't find it now!

Nevermind, found the thread and ODIN repartitions the /data, /dbdata, /system and /cache files. Same as voodoo except with /system included. Back to stock RFS yay!

Correct Odin repartitions everything or else there wouldn't be much point to it

Steps to move from RFS to EXT4

Hi,
need steps to change rfs to ext4? And does it require data wipe?
I am on SGS I9000 + 2.3.5 stock jvt
Regards.

No data wipe required, flash a kernel with ext4 included, boot into recovery and apply lagfix. Be sure to remove lagfix before flashing another rom in cwm.
Some kernels will require chainfires ext4 tools application.
Go to develop section and have a read up.

no data wipe but for security just make a backup coz sometime it hangs but not everytime.....just convert ur partition.

Now you are on stock ROM. To convert rfs to ext4 either you have to install a kernel that support ext4 and then go to recovery and then enable lagfix. Or you can go for a custom rom. My advice is to go for custom ROM like Darky...
