Ext3 as root filesystem? - Captivate Q&A, Help & Troubleshooting

Hi there,
I've seen all the posts about formatting the sd card with the ext3 filesystem, but i would like to know if there is a way to modify the root filesystem to be ext as well?
I know this is probably a daunting task, but im willing to learn and want to jump into android headfirst. Any suggestions would be appreciated. Thanks!

That's basically what Voodoo does, except it uses ext4 not 3. No such thing yet for Froyo unfortunately.

Well this may be OCD of me , but I like knowing the file system isn't some virtual filesystem. I'm still learning advantages and disadvantages of different file systems, but I know that FAT (or RFS) is horrible.
It sounds like I'd need to write my own ext4 driver, flash a kernel with that driver, make a partition on the main 1GB internal memory as ext4, and install the ROM over that. Am I missing anything, or does that sound right? And if that is right, are there resources on how to do that task?
Thanks so much, everyone!

first of all, you need to start out with source for 2.2, which is not available yet....so everything else is pretty much not going to happen until source is available. there are couple of 2.1 kernels that have already been built and they work pretty well.
**EDIT**
and source has been released for the i9000. we are close now

[Q] no ext3 in froyo 2.2?

Hi all,
I got my galaxy i9000 (froyo.bujp7 - v2.2 ?, kernel 2.6.32) since three weeks and as I'm exploring its abilities I came to wonder whether it's really missing an ext3 support?
The only reason why I need this file system is because I have a file which is greater than 4 GB in its size (it's a map file for navit). So as FAT32 won't be able to address such large files, I formatted my external SD as ext3 on my PC (Debian Squeece, kernel 2.6.34.1 - preemptive).
I was expecting it to work out of the box, since ext* is a native linux file system.
I browsed the net and all I got was some tutorials for app2sd and such. From what I think I've understood, I need a different ROM that supports ext3, is that correct?
I actually like to use the phone for a while before I start hacking its guts. But in case I really have to go through this, can anyone give me a hint where to start?
Thanks in advance.

Many of the custom kernels here have support for ext4 included as part of their lagfix schemes, e.g hardcores or voodoo kernels. Unfortunately, as far as i know the sd cards are always mounted with vfat instead of autodetect so you might have to manualy set that in the corresponding mount file.
Hope that helps.

[Q] [Webtop] Next steps: More space or newer Ubuntu? (Poll effectively closed)

----- Announcements -----
The poll is now being treated as closed. As such, since I would be unlikely to look back after moving to a newer Ubuntu, and since the two efforts are effectively incompatible (unless I wanted to try my hand at flashing a new /osh which... no), I'm concluding that there are enough users who are happy enough staying on Ubuntu 9.04 that I'll work on the union filesystem first before moving on to newer versions of Ubuntu.
----- Your regularly scheduled post below. -----
I believe I'm getting close to having a reasonable "first pass" of having a working Ubuntu on the Atrix. The interesting question becomes: what next? There are two steps I can see right now:
Get a FUSE kernel module working so that we can get a union mount for our modified Linux so that we can have more effective space. Note: this process is almost guaranteed not to work with the next option.
Now that source code is available for the Ubuntu files (I need to find out if we have everything we need, mind you), port newer releases of Ubuntu (starting with either 9.10 or 10.04).
Users, what would you like to see? The numbers at "closing" were 48/47/3.
i think it would be cool to see a 10.04 ubuntu - but what can be done with that without very much effective space? if you could find a way to expand the storage with an ubuntu port (even if it's after you port ubuntu, then find a way to increase storage) i think that makes more sense than trying to improve the inherently crippled current webtop setup
It would be great to see more storage! That is the biggest limitation at this point..
im all for 10.04 or 10.10
Wouldn't you require more space for this though?

Not really. Remember that the 1 GB filesystem file is a copy of the partition that Motorola ships. Upgrading would be swapping out Ubuntu 9.04 packages for Ubuntu x.yy packages, so it would be a matter of trading space, not strictly losing it.

Forgive my stupidity but... you are reffering to the 1gb file called Ubuntu.disk right?
Meaning, I can move that to SD to leave more space internally?

I'm pointing out that ubuntu.disk is 1 GB, but once it's created, it has no reliance on /osh. So as long as the Ubuntu x.yy installation is < 1 GB like the current 9.04 installation is, the space issue won't get any worse. No better, though.
And, no, moving ubuntu.disk to /mnt/sdcard won't work. If it did, I would have created a partition on the SD card to start with.
NUKE webtop and make it run ubuntu Pure ubuntu with the option to show it on the atrix screen too HEHE !
union mount! Also I bet this has non-ubuntu implications (internal and sd card as 1 mount point would be hot). Also why do we need a newer version other than to say "i have ubuntu x now which version number is greater than y was". What features are there in 10 over 9?

You're asking somebody who's typing this from IE9, so I can't help you there. But, interest seems high, and it is true that newer software isn't available as easily for older versions of the operating system.
Would it be possible to move it to SD card if there was an ext2 partition there? For example, on my 16gb SD card, have a 14gb fat32 partition, then a 2gb ext2 partition, with your mod mounting the latter instead of a file on /data.
I started playing with this idea yesterday, but ran out of time before I got it to mount properly in Android... Do you think it's feasible?

No, actually, since the initial idea didn't involve use FUSE to be able to do crazy filesystem tricks. I thought /cache was needed, though? If we can find space here and there, it might be possible to decrease the footprint in /data a bit so that people aren't squeezed so tightly on space.

/cache is only used for temp downloads (market apk installs, email attachment previews, etc) and OTA updates. The temp downloads don't take up much space - less than 50mb usually, but the OTA updates would probably be a a bit bigger. But who uses those right?
I'm one of those greedy people who have over 1gb of junk on their /data partition

[Q] Why isn't apps2ext supported on Cyanogenmod?

Hi, I have my phone usually a little bit too stuffed with apps, and even now with cyanogen, I'm starting to receive space warnings again. I know the easy answer is to make some room by erasing unneeded apps, but I'm not so eager to get rid of many of them. (Then I wonder why the heck the dolphin browser hoards 20MB of the internal memory even though the app has been clearly stated to store the cache on the SD).
Anyway, I was toying with the idea of the apps2ext, which I believe allows to move all the apps (or the system partition) to an ext3 partition on the SD, hence freeing a lot of space on the phone. I decided to read onto some documentation, just to find Cyanogenmod doesn't support it. And my question would be, why? Is there any problem with this kind of messing?
Thank you!
Depends what you mean by apps2ext, because that term gets used for generic processes, as well as specific implementation methods.
There are a number of methods than can be used with Cyanogen, such as Darktremors script, out even apps such as S2E, or Link2sd...

Apps2Ext is typically DarkTremor or a variation of it, but must admit I've never heard of the others.
I think the point here is to use an Ext partition rather than the daft FAT .android_secure Apps2SD in Froyo onwards.
Darktremors is more commonly known as a2sd.
When talking Cyanogen, apps2ext typically refers to the older system that was in place in CM5, but has since become unsupported. This is possibly where the confusion arises?
From what I can gather, the old apps2ext made some trick use of repartitioning to exploit the unused cache space that occurs on CM, as well as moving apps to the ext partition. Firerat has a working version, but it is no longer integrated in the ROM. I've used it, and you get way more space than with DT, but the maintenance is a nightmare... CM not longer support it because there are so many alternatives available (though none are as effective)...

IMO A2SD or Apps2SD is too vague, so I (and other folks) refer to it as Apps2Ext to differentiate it from Froyo's method.
And as for how CM5 did it, wasn't that just using DarkTremor? I could certainly be wrong, as I've only recently started using CM on my Nook Color.
I still assume the OP wants an Ext partition on his SD card used for Apps, aka: Dark Tremor.

Yes. DT was integrated into CyanogenMod ROM 5.0x. Then there was great wailing and gnashing from many when CM6.x releases lacked DT. TeamDouche stated that they planned to put it back in for CM7, but they never did.
OP: Please visit DarkTremor's XDA thread to learn how easy it is to implement on CM6/CM7.
No, CM5 (and 6) was NOT just DT integrated. Read this:

Thanks for the link... not applicable to my assertion AT ALL. Read the page twice, nada.
Please visit this one:
http://wiki.cyanogenmod.com/index.php?title=Apps2SD#Apps2EXT
The CM5 releases implemented a extX partition scheme that later came to be known as DarkTremors Apps2EXT. CM6 did not.
Another link, posted by none other than Firerat (possibly Danger-rat in a former life?). I guess the scripting/symlinking came along in the later, excised incarnations dubbed DarkTremor's Apps2SD, then Apps2EXT:
http://forum.xda-developers.com/showpost.php?p=6385186&postcount=2581
Your link to the CM wiki states that the apps2ext solution was integrated into the framework, not a script that tricks the phone into thinking the ext is internal memory...
Here you have Firerat (no relation) providing a solution to the apps2ext problem, where "the base is from CM5":
http://forum.cyanogenmod.com/topic/...p2sd-built-in/page__view__findpost__p__166163
Note that Firerat states that it is not perfect, but "better than scripted a2sd solutions" (read Darktremors)
Here is the xda Darktremors thread, with the title containing "Script" and "a2sd":

Hi guys, thank you very much for all the useful information! So, as you say, it's a maintenance nightmare...does it means trouble when updating the rom? What are the risks? I'm gibbs search a little bit regarding this dark tremor...thank you!
Darktremor isn't the nightmare, the repartitioning trick is. I would recommend using Darktremor, and staying away from the fancy stuff, unless you are really confident about what you are doing...
Ahh ok, from what I saw it involves a bunch of options in the boot menu. I was doing the goddamn backup of the SD card, it took ages. Now I'm ready to start. It's a pity there isn't yet a partitioner that makes the partitions without erasing your data (kind of partition magic of sorts).

Isn't GParted able to do this?
Btw, if you don't want to play through recovery menu, go get S2E from Market, it is free and it works great IMO
Sooo here I am again!
I'm not sure at all if this is working. After booting the first time (it took a looong time), I was greeted with a "welcome to Nexus One" home screen. I have lost all my data, apparently. Not very sure regarding that.
I'm also not very sure if this is working at all?
Let's see, I made a 1024MB Ext4 partition, inside the 16GB SD card. Now when I see Manage Applications, it shows me 136MB free...But I don't get it, wasn't I supposed to have more space?
The other possibility I'm thinking, it's just listing the internal memory space, while all the applications are in the SD Ext4 partition.
If that's the case, then if I install stuff, it won't be listed, and I won't be able to know how much space I have left, right?
I don't know, can anybody clarify this? Thank you!
If you're using the DT script, you need to activate it by typing either "a2sd install" (apps only), or "a2sd cachesdreset" (apps and dalvik) into a terminal emulator (need to type "su" first, to get superuser rights).
To see better idea of the space allocations, use Titanium. It has a nice breakdown on the first page...
Yup, I typed the commands from the adb shell, which I reckon is the same. But now everything seems like a big loss in contacts and stuff.
I have a question: If I install a new rom (cyanogen nighties, I'm running), will I lose the DarkTremor script? And if I restore a full backup made with Clockworkmod?
I'll try to fight with Titanium backup, but for each app to restore I have to manually accept the installation...Seems a lil bit pain in the ass
Are you sure your contacts are set to sync? You can lose that setting from nightly to nightly...
When updating between nightlies, I believe you can flash the nightly then the DT script and all should be good (I always wipe).
The DT settings etc will be backed up with CWM backup, so you can restore that and it will include the ext also.
If you buy Titanium Pro, you won't have that problem... xD

[Q] Convert SDCard to MainMem so External_SD becomes SDCard?

Hi there,
Is there a way to make the add the internal SD card to the main memmory? So that there would not be an internal SD card anymore?
I do not mean swapping the moutpoints around so my External_SD becomes my primary and my internal my second....
I want to get rid of the internal one alltogether (adding it to main memory).
I figure that I'll have to format the storage in a certain way... would that do it?
Can someone tell me step by step what to do?
I do have CW-mod installed.
I did search the forum, but couldnt find anything conclusive. Just hints that it should be possible...
If there already is a thread where all this is explained, please point me to it, because I couldn't find it.
Thanks,
Pfeffa-rah
I don't think this is possible , never heard of someone who did it
I have no idea how to do that. My question is... why would you want to do that?
Having an internal_sd partition adds the benefit of having big app data (such as those in Gameloft games) sit in a very fast partition and still be called "sddata".
Also, it's mountable via PC so everything in there can still be backed up. So it's best of both worlds really.
This was discussed some time ago in this thread: http://forum.xda-developers.com/showthread.php?t=1013575
There were ideas on how to remount the cards at boot. I myself come to the conclusion that since more phones start to behave in this way, app developers will have to start dealing with it. It just sucks they are mostly slow on the uptake. My main problem was the Spotify cache location being hard coded so I resorted to hack the Spotify apk.
PS. salisbury_steak: What is it with people like you that every time someone has a question on how to do something, your immediate response is "But why would you want to do that?!".

That was actually an honest question.
I wanted to understand why he wanted to do it. (i.e. What would be the advantages of it.) There was no supposed sarcasm in there.
how about the ability to install 5x more applications?
Having that stupid 5gb partition as sd card and the real sd card as a sub folder is retarded...
My 32GB class 10 cars is a lot faster than the internal one.
The internal 5gb memory is MUCH TOO SMALL!!! Most apps don't allow you to store data on the external card. If you like me and many others install some games that download aditional data + a nav app that downloads maps for europe + some streaming music app like wimp that can cache music for offline play then you are ****ed with LG's setup.
The setup CM7 uses solves the main problem but effectively wastes the 5gb by mounting it at emmc where like 0,0001% of apps are able to access it.
So adding those otherwise wasted 5gb to the main memory would be great. But i have not seen any solution to that yet :-(
Thank you Gensplejs for explaining that to them. I had no idea how to reply to that since it seemed so obvious to me.
This thread was ment to be a question about how to do it and not to discuss the usefullness of it. That is where I lost the way in other threads...
So, thanks for your replys all (realy).
But now, back On-Topic:
How would I do it?
Sent from my LG-P990 using XDA Premium App
Please don't blame me if you tried it and you screwed up your phone.. It's your choice...
Well, I don't know if this would work, but this is how I would do it (accepting the fact that I'd loose almost 2GB of /data's free space):
1. Format your internal sd card to the same file system as your /data partition is (ext3 or ext4)
2. Copy every file from /data 1:1 to your sdcard (cp -R /data/* /sdcard)
3. I don't know when and where the partitions are mounted (maybe init.rc??)...anyways change the target there and let /data point to the internal sd card partition (so it is ensured that it is mounted automatically to the new location)
4. Reboot and keep your fingers crossed
I think i figured how to do it in theory. First we need some free space at our microsd to cp /data. Then we should repartition with fdisk /dev/block/mmcblk0p8 and p9 into one partition and change vold.fstab to mount only externalsd at /sdcard as we do when we swap partitions. In theory it should work but i cant test it right now or make a script since ve gone vacations and i dont have a pc to restore in case of error
I agree.. certain apps wont store to sdcard.. its better to use the whole 8gb as phone storage, and use external sdcard as default sdcard.
Sent from my LG-P990 using XDA App
What ive found till now is that sd swapping is easy. You can do it by tweaking only vold.fstab. But repatriationing is a pain in the ass. Looks like lg has "faulty" partitions or something and to do it you must mesh up with with almost half partitions.
I had to rebuilt boot lgdrm recovery data and sdcard to make em half work. So it probably isnt worth the trouble. Also I think init.rc is built on the boot. So just remounting internal sd to /data wont work either.
sectors is not space
it says 7996, so thats 8GB
i saw it in hurry. the brain sometimes belives whats he want to belive
sorry
New to XDA
Hello everybody,
I'm new to android and i'm trying to find out how to solve the problem posted in this thread.
I see you've got the awnser but i don't know how to do this.
I've been searching google and XDA for ever but i just can't find the awnser.
Could you make a step by step howto or point out to a post how to do this.
I mean converting your external sd to ext4 and change the mounting points.
I'm a complete nood, i didn't get adb to work on my pc, ext4 recovery is not for the p990 2x.
I've read something abbout changing fstap for swapping te mounting points for sdcard and emmc, witch is also ok for me, but formating to ext4... wel i frankly don't know how to do this.
I'm quite stuk on this.
The only partitioning experience i've got is Gparted in Ubuntu or repartitioning in Windows 7.
Thans in andvance!

Thanks davjan,
As far i can see it's indeed not worth it.
I wil have to go on and try to find out how to change the filesystem to ext4 and swap the internal and external sd.
That way i get more usable space instead of a big datastorage witch cannot contain program data.

what rom are you using? is your phone rooted?
swapping internal with internal sd is very easy
and most of the roms here on xda are ext4 , if you instal one of them they autoconvert to ext4

I you read the link provided you'll see that it makes what you want: grow internal filesystem = lower SDcard usable space. The only thing is that it doesn't seem possible is to use the whole space: system limitation. 75Markus tried high /system and /data values and phone didn't work.
See in his Mediafire Folder, 'Nvflash + guide for changing Partitions:
http://www.mediafire.com/75markus
Ext4 is now common with custom ROMs (in fact all of them).
You should search in sd-ext partition system, which was designed to artificially expand filesystem on older phones using an 'ext' partition. I didn't heard anybody using this on O2X.
If you use CyanogenMod based ROMs, your external card will be mounted ad /sdcard by default.
Switching internal and external SD
Thanks guy's,
I'll check it out.
I've been using cyanogenmod 7.1 stable with vorkkernel 20110208.
But that gave me batterydrains while using maps and nextvid ate the same time (while i'm driving).
Now i'm trying MIUI 1.11.11 with latest swift extreme.
But MIUI is very buggy so i'm thinking of going back to CM.
The only thing is that my phone won't boot with the latest vorkkernel.

Ext partition

Ok this might be a noob question but im going to ask it anyway..
Whats the point of creating one on the sd card?
Is the only benefit that i can move my apps to the sdcard with tools like link2sd?
Or can i also let the phone think i have more internal memory?
Im running the jellybam rom but i cant find any info about ext partitions, anyone who can explain it to me?
Thanks and enjoy your weekend guys

I don't know that there is an advantage for ext3 with a flash drive or SD card. See:
http://www.phoronix.com/scan.php?page=article&item=linux_f2fs_exfat&num=1
The article is mostly about f2fs vs exFAT, but some comments included.
"Earlier Phoronix tests have shown that F2FS from flash storage is already generally competitive with the popular Btrfs and EXT4 Linux file-systems."
"Seeing a user-space implementation of the Microsoft file-system outperforming the in-kernel "Flash-Friendly File-System" came as a shock."
With already slow SD transfer rates due to the media itself, I doubt you'll see an improvement in system performance. Maybe someone here has a better idea. I don't. But the worst you can do is nothing.
My only concern would be hooking up the 970 to a Windows machine; "stock", Windows may not see the extra ext2/3 partition. You'd need Linux to do that.
Hmm i've readed the article but cant find any info about what im looking for..
Anyone else who can help me?
