Lately, I've been flashing a bunch of different ROMs, and in each one, they require you to have a certain amount of your memory partitioned. I'm not too experienced in this particular area and I've been wondering what is the point of all the partitioning?
Why can't we just have one partition and run things off of that like with a computer running on windows??
What are the differences between ext2 and ext3 and so on?
So far, I've only been able to find out that the swap partition is for memory extension when the phone is currently using all of its ram, it can convert some of the sd card's memory to use for programs. Can anyone provide more insight on this?
I've asked myself the same questions .... hope someone will explain...

It would be helpful if you mentioned what phone you're using.
Generally the reason you have a /data and /system partition separately are so that you can either upgrade or reinstall Android without losing your data. If you reflashed whatever ROM you're on right now again, without wiping anything, all of your apps and settings would still be there (although any mods you flashed to modify the ROM itself would need to be flashed again).
System - Holds Android itself and any apps that came with the ROM. Some ROMs (or rather updater scripts inside of ZIP files) will install some apps in the data partition to save space.
Data - Your settings and any applications you installed.
Sometimes you WILL have to wipe everything to go to a different ROM, but for the most part if you're on an official ROM that came with your phone, and your carrier pushes an update, you don't have to.
I'm guessing you have an older phone if you need to make a swap file. A swap file is like RAM in the form of a file; if your phone runs out of usable RAM, it can use the [slower, but useful] swap file, which is like memory you reserve from storage [your MicroSD card]. Windows and other OS's use swap files too, but given how much RAM we have in computers today, we hardly ever use it.
EXT 2 fs - A non-journaling file system. It's quicker than EXT 3 and takes up less space for itself in memory (not for files, just for itself), but it's more susceptible to corruption if you randomly turn off the phone while a file is being accessed.
EXT 3 fs - A journaling file system, which means that it keeps track of any file operations within itself. While it's slower than EXT 2 and takes up more space, it is more reliable and is safer in terms of file integrity.
There's also EXT 4, but only certain phones are compatible with that, mostly Samsung Galaxy S phones.
tl;dr: It keeps everything modular.
Thanks for the explanation. It helped

I would like to know a couple of things...
1. Internal phone storage & phone memory, what is the difference and is there any mods people are doing with them as far as combining or something?
2. SD partitioning... are people still doing this and if so what are you recommending?
3. Swap... probably a thing of the past, but just would like to know.

alright lets make this world a better place, i'll tell you what i know
internal storage, is basically yours to use, add your music pics or whatever, just like how u use an sd card, phone memory aka application memory is reserved for apps only, no way of combining them, dont need to anyways, sd partitioning i never tried but i think its says it all, dividing your sd card into two or more partitions..make seem like you have two or more, u can reserve one just for music or pics or roms
and what do u mean by swap??
ooh yah if i helped a little hit the thxs button, imma collect now too lol
I came from from the G1 where it was standard practice to partition into fat32/ext/swap. Since moving to the G2x I have not needed it. Phone is super fast without swap and more than enough space for apps.
As for combining internal and external SD cards, I don't think I've seen that yet...

I've never seen them combined but don't know if you can because if you remove the microsd, it would get all screwy.
I don't even use internal unless the rom does. I have a collection of apks/walls/music and my titanium files on my SD... everything else is expendable.

Internal phone storage is where your system files are stored. It is also where apps from the market are installed. Phone memory is utilized by the stock roms as the default "sdcard". By default this is where your photos, music, documents, etc are stored. There is also an external slot for a physical sdcard. This is actually mounted to /sdcard/_ExternalSD with a stock rom.
There is no need to partition the external sdcard. There is enough space on the phone by default and it probably wouldn't be worth the hassle to make it work.
I don't think you need swap with this phone.

Thank you for clearing this up, so in clockwork recovery why does it support EXT 4? Is that just the format it saves a back-up in?

No. Ext4 is a type of filesystem used commonly in Linux, just like FAT and NTFS are used with Windows setups. There are some roms that will mount your system as, or even fully format your system into a ext4 filesystem. Clockwork supports that filesystem, meaning it can be used to install ext4 roms.

No you simply flash like you would any other rom. If the rom actually formats your drives to ext4 i beleive you will have convert back to ext3 in order to flash an ext3 rom. There is a conversion utility somewhere on here if you search around. Someone else wanna chime in to verify about the need to convert back to ext3?

Yeah I read about the EXT 3 to EXT 4 dilemma on here via CM7 when it was upgraded from an overnight build or something... I think it had to do with restoring apps or data? Really appreciate your information, this finally clears up the confusion
p.s. thanks'ed all your replies
Hi all,
So last night I decided to give Cyanogenmod7 a try. I came from MIUI.us 2.1.20 - I just love MIUI, but it's a bit too demanding for the Milestone. So I have CM7 up and running, and it is a lot more snappy. But now, I'm having trouble installing some apps.
I tried installing my bank's banking app, but it didn't install - checked the market and it doesn't appear. Same thing with WhatsApp!! If it were working, I might just become a CM7 user..but it's not working.
Am I missing something? I installed after doing a full wipe, after which I installed DT A2SD scripts and then gapps-20111216 (although didn't see gmail or market etc after gapps, so installed those via apk).
What's the deal here?
Thanks.

Ok, just wiped again, and reinstalled all. CM7 then gapps then dt a2sd. So far it's working.

googleservicesframework.apk and vending.apk are all you need for using market. Try to reinstall them. May you success.
Ok, so now my problem is A2SD. It's not working! A2SDGUI refuses to go in, and when I do a check, I get a segmentation fault...I've never had this issue before. I've tried reinstalling DT A2SD from withing recovery and still, nothing. Please assist, I just need to get set up properly now.

DT scripts dont work ...use an external partition (app2ext)
d.casper.b: CM7 for Milestone already comes with its own ap2ext scripts that are automatically used if there is ext partition present on your sdcard.
You should not install any 3rd party app2ext scripts as they are very likely to be conflicting with the scripts that are already there.
Thanks kabaldan.
I'll check it out.
I was even going so far as trying to use Link2SD from the market..
How'd I know if it's working? By monitoring the available internal storage?

when you will enable app2ext you will see the total space in your storage rise to 197 mb
I am not winning. I did a factory reset and flashed cm7 and gapps (not dt a2sd).
I did a test, internal storage was at 191mb, then I installed opera mobile and it went down to 182mb. Then uninstalled it again. Went into cyanogenmod settings and set install location to external. Installed opera again, but it was no different. Moving it to sd under 'manage applications' increased the internal memory again, but that's just moving the app to the FAT32 partition of the sd card.
So it's not seeming to work for me for some reason.
Sent from my Milestone using Tapatalk
EDIT: I really don't want to be a nuisance, but now, looking at the available storage using "Quick System Info", I noticed after uninstalling "Opera Mobile", 9mb was freed on internal storage & 13mb on the ext partition.
So, perhaps it is working, and since the dalvik cache is (I assume) on internal storage, the storage is still decreasing. Am I correct? If so, is there a way to also move dalvik cache to the ext partition - I had it like this on MIUI & never looked at available memory ever again.
First of all, have you really partitioned your SD card? Make sure you followed the 3rd step on this guide: http://www.mrmuh.com/2012/01/update-a-motorola-milestone-from-motorola-firmware-to-cyanogenmod-7/ . You should have your SD Card partitioned with two partitions, the first should be FAT32 that's used normally on Android, and the second EXT3 or EXT4. Obviously, make sure you have a backup of your FAT32 partition before partitioning.
Second, you should understand how the apps2ext scripts on CM7 work. Application installs that would be stored on internal memory are rerouted to the EXT3/4 partition on the SDCard. This happens at the underlying system (linux) level, Android (that runs on top of linux) is not aware of this rerouting, so, as far as Android "knows", apps that are rerouted to the EXT partition are on the phone's internal memory. That means that you should make sure that apps you need installed on the EXT partition of the SD card are shown in "Applications > Manage applications" list to be installed on the internal memory. Yep, it's confusing, but once you understand how it works and why it works that way, it makes sense.
Third, the fact that apps are rerouted to the EXT partition doesn't mean that everything about the app will live on the ext partition: it means only the main application package will live on the ext partition, application data is still stored on the internal memory. For most apps, the amount of data used for application data are much smaller than the application package, but in some apps the amount of application data from the app may often surpass the size of the app itself - for example, in my phone, Tweekdeck stores about 9Mb of data, which is about 10 times the size of the application itself (820kb) - presumably this amount of data is cached tweets, pictures, etc. But that case is usually the exception, not the rule, I've just mentioned it so you understand that using apps2ext doesn't mean your internal memory will always stay unused, it just means it will be used (way) less.
Finally, regarding the CyanogenMod Settings location setting, if you understood what I said above, you should now understand that it should actually be set to always install to "Internal", rather than external. However, there's a bug in this that you should be advised, that not all apps will respect this setting: some apps will install to external regardless of how you've configured that setting (meaning the app will use Froyo/Gingerbread native Apps2SD, hence being installed to the FAT partition of the SDCard). So, when you install a new app, check on app management if it didn't get installed to the SDCard, and move it to the internal memory if that's the case. For these kind of apps, you'll have to do it every time you update the app too.
Thanks, I edited my previos post..
I actually have 3 partitions, a FAT32, an ext2 (maybe it's ext3, but doubt it - partitioned some months ago, so my memory's hazy), and a SWAP - which I should get rid of, but am too lazy.
I understand entirely what you've said, I know that internal is really ext if working, and sd is FAT32 partition.
You see, I'm just new to this rom and have to trial and error until I understand, with miui you just flashed the rom and the a2sd scripts and didn't bother again (maybe only to move an app that installed to FAT partition). But it seems CM7 is simply just to flash the rom and you're good to go. But as I was pondering in my previous post...is there any way to move dalvik cache to ext?
Thanks for putting up with me..I'm almost there.

in the market you will find an app called s2e which moves app data, davlik cache to sd
also link2sd also free's up more space and makes cm7 snappier
please don't install such things to CM7 for Milestone unless you know what you are doing and you are able to resolve conflicts with the existing scripts
dalvik-cache is already moved automatically
if you want to free more space in /data, enable lib2ext to move native libraries to ext - it's mentioned in the changelog for 7.1.2 release
app data itself should not be moved as it can cause instability

Yeah, get rid of swap, there won't be any use for it (for now anyway) and it's best for you at this point to have a known working structure (two partitions, 1st FAT, 2nd ext3/4) for your SD as you're troubleshooting your problems/questions, it'll make it easier for us too as this will eliminate potential points of failure or inconsistencies. And you should really consider upgrading to a journaled filesystem, either ext3 or ext4. Using ext2 is unreliable because Android doesn't umount the ext partition cleanly on reboot or shutdown, so you may have problems with apps disappearing or misbehaving every other reboot. Using ext3/4 with journal elimitates this problem since the journal is just replayed for the uncleanly umounted partition and the filesystems behaves more consistently.

The apps2ext script built on CM7 should do this by default - you probably already have your dalvik-cache on the ext partition. To check this, go into OR, enter the console and type: "ls /sddata/dalvik-cache" . If it returns a list of files, you've already got the dalvik-cache on your ext partition. Another option is setting the option dalvik.vm.dexopt-cache-only to 1 in the file /system/build.prop . This will put all dalvik-caches (both from user apps and system apps) on the phone's internal cache partition, thus still freeing space on the internal memory but without using the ext partition, but that's not recommended if you install too many apps because the cache partition may run out space and that will spawn all kinds of weird behavior on Android. The safer route is just using the default configuration anyway (user apps dalvik-cache on sd-ext).
Another option to further reduce internal memory use is using lib2ext, that will move user apps native libraries to the ext partition, but the memory gain in this case is dependent on which apps you use and how big their native libraries (if they even have one) are. To activate it, just go into the Terminal app (with Android booted) and type:
$ su
# lib2ext
And reboot. The libraries will be moved to the ext partition during boot. Make sure you have a big enough ext partition to hold everything (apps, dalvik-cache and apps libs) - the size to recommend is very dependent on how many apps you use and how big they are, but I'd say 512Mb would be the bare minimum.
in the market you will find an app called s2e which moves app data, davlik cache to sd
also link2sd also free's up more space and makes cm7 snappier

DON'T! JUST DON'T! These third-party apps will cause all kinds of problems with CM7 builtin apps2ext.
EDIT: Oh well, Kabaldan already put all my rambling much more succintly than I could... I'm way too talky
well i was jus trying to help.. .anyway guys thanks i guess i won't be needing those apps anymore ...sorry for my noobness
Thank you so much guys!
It seems like it's working. I will check out lib2ext & the other suggestions tonight or over the weekend (on my way to work now).
I must say, I thought the move to CM7 would be a temporary one, but the speed gain is just what I needed, & the tweaks I thought I'd miss I am finding hidden in the settings .
Just wondering on the battery now - but I've been fiddling non-stop.
So let me play a bit more the weekend & I'll merge my ext2 and SWAP partition into one ext3 partition.
Thanks all, and kabaldan for your hard work on this rom.

Just as I was on my way...
Everything's running fine, A2SD works. But now, I partitioned my SD card with a 2nd partition (ext3, it was ext2), but now widgets are not loading. Checked the apps install location, and it's 'internal', ie. ext3. I never had this before. I think maybe it's due to the filesystem now?
EDIT: Ok, ext2 is doing the same. I can't keep starting from scratch the whole time guys.
EDIT2: It's now suddenly working! Just have a Fat32 and an Ext3 partition. But I don't understand because it's been setup like this twice before with no success. I'll hold thumbs!
PS, CyanogenMod is quite up my alley now, speed is awesome and I'm happy.

The reason this mod came about was because the older phones like the hero and whatnot had very little system memory, but after running firerats script it would give the hero like 300mb of system memory on Sense, so its a major memory increase and it would most likely eliminate the need for a2sd

Might be a better idea to do use a sd-ext rom with a partition on your sdcard. The shift has so little internal space in general, it might be a better idea to do that if your looking to get space.
Also, the OG Evo has a MTD memory, and the Shift has EMMc, which I believe is a lot less flexable to being changed than MTD is. Tell me if I'm wrong though.
Thanks for the quick response guys, I was really hoping to increase my data partition. There's so much room left untouched in the system folder. So no hope in doing this I assume your saying?

You really wouldn't get much more outta system for data as you would a ext partition. Sd-ext is virtually unlimited depending on the size of your sdcard.
Not to mention you would have to revert back to the stock settings in order to install a sense rom for updating prl and such things. This could be very tedious.
Firerat's initial custom mtd was for the G1, which is a aosp phone stock and does not need tons of system/rom space.

I'm currently running bhundven's herring CM9 with no kernel modifications and CWM 6. I find that the internal storage for this phone is very low and only holds a small amount of applications, especially since many apps seem to not want to install at all (about 3/4 of the time I try to install things, I get either "Package invalid" or "Insufficient space available", which is extremely annoying and might be a separate problem).
Is there any way that I can get sd-ext to work on this phone with this setup? I'd rather not switch kernels (I'd love to get TWRP recovery but the flashable doesn't work for me and I don't want to switch kernels).

That seems like it just switches the internal and external storage, not making an ext partition on the SD card. But can things like this really be done through an app? I thought these things had to be done through init.d or build.prop scripts.

The app creates an init file. Or so it appears. Like I said I don't use it. It seems that raze does and I'd defer to him here. Either his app or the one I linked should work fine.
Thanks (given) to both of you. And any ideas on what else might be causing the invalid packages when downloading from the play store? It happens even though I have much more free app space than I would need (eg. I had 119 MB of free space and a 30 MB app download failed).

Another way is to create ext4 partition (about 1G is usually enough) on you SD card with free MiniTool Partition Wizard and then use Link2SD to link apps/dalvik to this partition. I've been using it like this for a long time and it works fine. There are plenty of guides on the Web how to do that.
I used CWM or TWRP to create the sd-ext partition. You need to create that first somehow... if MiniTool Partition Wizard will do it without wiping the sdcard, that's better than recovery though.
My method was boot to recovery, mount sdcard, copy everything to computer HD, unmount sdcard, partition sdcard with 2 GB sd-ext (because I wanted lots of space, but I'd probably cut it down to 1 GB next time), mount sdcard, copy everything back from computer HD, unmount sdcard, reboot to system. Then launch Mounts2SD, pick what format you want the sd-ext in (FAT or ext2 are the fastest, but you can take ext3 or ext4 if you're not going to just disable the safety features) and what stuff you want moved over.
Edit: Just found this link, which I haven't used but which explains how to do the sd-ext with MiniTool... apparently MiniTool DOES still wipe the partitions though, so you may as well just use CWM/TWRP and make your life easier.

Yes, but our herring kernel does not support EXT4 partition, I tried it myself
and it didn't work. I had to create EXT3 which is supported by almost all kernels.
Eh, my results varied. Worked fine for me with ext4. And worked fine for my wife as well.

The OP says he's running CM9. That's what I'm running but I use Proton kernel as CM9 kernel has a video bug, and ext4 partition works just fine for me. Strange if Bryan really removed ext4 support, it's just a line in the config file.
Successfully made the partitions last night but my phone won't mount the SD card anymore. Was trying ext3, I'll try ext2 and ext4.
EDIT: Fixed the problem, changed my partition to ext2 and set both partitions to "Primary" (not sure which one did the trick).

Successfully made the partitions last night but my phone won't mount the SD card anymore. Was trying ext3, I'll try ext2 and ext4.

Make sure that you make the first partition Primary/FAT32. This will be your normal SD card. Just take about 1GB of space from it at the end. Then make second partition Primary/ext4 with size to the end of the card. You can try ext2/3 but I don't think it is really necessary.
MiniTool will NOT wipe your partition if you do it right.
dsexton had a guide posted on how to do it.
Is it worth making a swap partition? If I remember correctly it significantly degrades the life of the SD card (and microSD's are delicate as it is), and I don't know if it would significantly increase performance.

I also created 128MB swap partition, not supported too and not mounted.
I tried to used swapper2 app from the market, but it says not supported by
kernel. Now I lost that space till I feel motivated to format or repartition the SD
card again.
I am using hefe kernel btw on AOKP milestone 6-5.
No swap.
