[REF]Streak 5 Partition layouts
there are new alternate partition layout, after reading, i wonder why /system and /cache is set from 256MB to 512MB why not higher exampe to 1GB or more, is there any information for this?
and another question is what are roles for each partition?
thank you all very much
There's no point, making /cache bigger simply means less room for /sdcard, it rarely ever needs that much space and is usually either empty or nearly empty.
Same goes for /system, very few devices naturally have above 512mb, the rest would simply go to waste.

usually for /system is where people would like to integrate applications by default .. that means for personal preferences ... but still.. you dont need it that much because you have more space for /data which is never full for your entire streak usage ... 300 applications? still there is space left at /data and even more space left if you use 16GB card...
Integrating into system is very counterproductive, unless you integrate updates to those apps every time they get updated. Otherwise you end up with a copy in /data and a copy in /system.
A larger /system definitely helps me at least, I'm working with a couple roms that are in the 380mb range, and MTD6 is only 260mb large.

yup.. using link2sd would mean i can reintegrate updates into the /system ... so .. its ok then ..
Ok, i understand now. Thank you all for those explaination

How do we actually apply or change these partition layouts? thanks
at my signature... see the thread i created there...

Ok so my question is... Should the cache file setup for a2sd be 0 or not? Some set it to 0 stating that the internal cache is faster and with apps on sd there is plenty of internal cache. Some set cache file when partitioning external. Should we not be setting a cache file up at all when partitioning for a2sd?
Thanks for any input. BTW I have 256mb cache, 1Gb ext3, on a 16Gb class 6 card.
I think you mean swap, not cache.
BTW, freeing up space in the system flash ( "/data" ) partition will not improve your phones' performance - unless you take other specific actions, that empty file space just sits there unused - it is not reclaimed to be "put to better uses". Not that it matters, anyway: it's flash memory, after all - not RAM (it's dog slow).
Your results using swap will vary. Some have reported that (most notably in the case of the browser or the "Home" provider), that using plenty of swap will prevent that app from being harvested, and so you don't have to wait for data operations to repeat (e.g. browser page reloading) when bringing the app back into the foreground.
OTOH, a good argument can also be made that adding swap merely defeats Android's built-in method for managing application harvesting, thereby making the device actually slower for a variety of operations - the automatic application harvesting kicks in "too late", and the phone gets slow for routine operations.
Having said all that, I'll tell you that I set mine to 0 (no swap at all); swap generally only helps improve your situation after you've already started to get into trouble; better to just stay out of trouble in the first place.
Good luck

LOL... I feel like an idiot. Yep swap would be the intended question. Thank you for the very educated response, it truly helped.

hi there i just got my sgs2 but when i looked at the internal memory it says ive only got 11.50GB space on my internal sd not 16GB has anyone got this or is my phone faulty ?
Thanks for the help =]
It is like that. Some useful taken for the system, apps, etc.
$1 gets you a reply
You never get the full 16gb from the start and then around 2gb is used for system apps u wish to install which leaves u with just over 11gb for storage.
Every1 is the same.

oh oright cheers mate
HI all
How can i see the over space ? I d't want too use it, just too verify that the total space is arround 16GB.
Thanks.
Take the system partition, add the sd card partition (not the external one, thats the sd card you put in, the sgs2 just calls extra internal storage the sd card)
Then take off a bit for the space taken up by file system formatting, hidden system bits, cache etc.
And you should have 16GB
go into settings > storage
The numbers you want are "USB storage" and "Device memory" device memory wont show total, but if you go to settings > applications > manage applications, and look at the bar at the bottom it will show the device memory used and free.
Or get a app from the market.

It is not as easy as it sounds with adding partitions as there are 12 partitions on a Galaxy SII, most of them not visible to the user.
If you have a file manager on the phone which can display files in /sys, then display /sys/block/mmcblk0/size (as a text file). This should display a number in 512 byte units. When you multiply this number by 512 you should get the total capacity (not including the space used by the primary bootloader maybe) On my phone I get 15,756,951,552 bytes, which is roughly 16 GB (not 16 GiB)
Well yes, but I don't think the average person will want to count down to the byte
Nice detective work though!
There is some smaller partitions (1 - 6) summing up to 46.5 MB
Then there is
- cache 100MB
- modem/radio 16MB
- system os partition 512MB
- user data partition (where, among other things, installed apps and their data are stored) 2GB
- some weird "hidden" partition I have no idea what's stored on it 512MB
That roughly summs up to 3.3G.
Addup the ~11.5GB you see as /sdcard and multiply a few times by 1024 and you get something close to 16000000000 Bytes -> there is your 16GB.
For marketing and advertisement reasons capacities are always given as "millions of bytes" with a factor of 1000, not like computers deal with it with a factor of 1024.
For that already a 16GB device shows only up as around 14.5GB on a computer.
That's also why your "1TB USB HDD" from the electronics market only shows up with something around 900GB.
Wanna see it for yourself, open up a terminal or adbshell on your SGS2 and type:
cat /proc/partitions
There you go

This partition has a (hidden) .ngmoco directory. As far as I remember I have seen this directory on a non-hidden partition too so this might be used to preinstall additional packages when the Android device is booted the first time.
Only about 20M of this is used on my device so thats somewhat a waste of space

Yes and no. It is not for marketing purposes only although they are happy to announce higher numbers. The official standard for units (gramm, meter, etc.) state that kilo is for 1000 units , mega for 1000000 units etc. The "standard" used for bytes / RAM conflicts with the standard of the SI units and is discouraged to use.
There is a "standard" which explicitly states that a factor of 1024 is used, but almost nobody uses this "standard" because it looks weird and unusual. Acoording to this standard, 1024*1024*1024 bytes are called 1 gibibyte (1 GiB). Most people (including me when I don't explicitly think about it) and appications still call this 1 gigabyte (1 GB) which leads to confusion.
Think all for these precisions. I'l take time to analyses and follow your answers.

PS : Sorry for my poor English
Some more exercise for the analytic minds here, why do Galaxy S with same 16GB Internal SD has 13.5GB after taking 2GB (RFS or EXT4, etc.) for data partition and possibly around 500MB for system?
I understand that instead of 1.8xGB as used in SGS1 is lesser than 2.1xGB in SGS2 for data partition which should include dbdata, cache, etc like in SGS1. Also accounting for those hidden partitions, we still don't know an additional 1GB lost (swap partition?)?
I would appreciate inputs from someone who knows how SGS2 utilizes internal SD and if we could repartition to reclaim some space.

exactely 16G, nothing lost or unencounted for.
Not a file explorer type app, but something more along the lines of Windows Disk Management utility, that can show the physical partitions and sizes of all connected storage devices. If it can do more, like show the amount of used and free space, and even what files are in each partition, all the better.
Something like this?

Storage Analizer, Disk View, DiskUsage. The last one shows also grafically the storage use.
Byte Map shows disk usage as pie chart.
It looks like Storage Analyzer only works on external storage, and DiskUsage only on external storage and internal app folder. I'm looking for something that will display the entire internal device, including areas only visible to root (my NT is rooted), plus external. It looks like Disk Space and DiskView will do that. I'll have to check further.

Disk Space doesn't appear to work too well on my rooted NT. DiskView is better, but it doesn't quite work the way I'd like. It's still a folder view paradigm, and it only shows space used. I'm hoping to find something that allows examining the storage devices as disks - partitions, total space per partition, space used, directories in each partition, etc. Byte View might do it, but the free version only seems to work on external storage. There's not enough info on the paid version to know if it will do what I'm looking for. Although it is cheap enough.
Try SanDisk... (Oh, God, I forgot the rest of the name). Just search SanDisk on Market and you will find it.

Paul, so close! It has the right look, but will not show the full set of partitions for the onboard storage. It only shows the "content accessible" 1GB partition. If they made this root accessible it would be perfect. It looks like they designed it for people who just want to manage their loaded content.

Sorry orb3000. I thought I was in the right place because I was asking for a recommendation on an app. Thanks for the move.
OK I came across this problem last month & tried to find a solution. I discovered many posts to the same problem however I was only able to fix it by doing a factory reset. The problem has come up again & I'd rather not reset it again. It only comes up after numerous picture uploads to Facebook. Until I do that my phone runs fine. I'm running Open Kang if that makes a difference. Given this information does anyone have a suggestion as to how to fix it? It was suggested that I flash a new ROM as maybe the one I have is too big? Starting to get extremely frustrated with a phone I've only had since April & really know nothing about

This is (as others suggested) a problem with the ROM you have installed. There really is no way of getting around a wipe, but you can download an app called "Titainum Backup" and backup your apps from there. Once you get into your new ROM, simply download Titainium Backup again and restore your apps.
As far as fixing the problem goes, I would reccomend using ODIN to flash back to stock, then flash CM9. (However, I am sure that flashing from your current rom directly to CM9 would work just as well)
The real reason this is occurring is the mounting of the /datadata simlink to the /data/data partition, this is actually in the kernel and sets it when flashing, not the rom. That partition stores the data for applications, and continues to grow as apps run. Often times when you sync alot of emails it will also fill the partition when its mounted as /datadata, so that makes sense with your pic uploads to facebook, now I'll tell you why.
Early on in ICS builds, we had two schools of thought. If you mount with the /data/data partition, you have essentially 2GB of space for that app data, however, this comes at the cost of decreased performance and much slower application response times. If its mounted with /data/data symlinked to /datadata, it clips that partition at about 180MB, a lot smaller, but the increase in performance is phenomenal.
So it was damned if you do (slow response times) or damned if you don't (less space) for those of us in the rom game. I think most (myself and DD included) made a conscious decision after lots of testing, to use /datadata with less space, for faster performance.
You may be easily able to resolve it by performing some simple app maintenance. On apps like email and gmail, set your sync interval down to a few days, uninstall unnecessary applications, and with facebook, I don't use it myself, but try clearing its cache if there is a setting for that, or go into apps in settings, and clear the data for the application. You may have to sign in again, but it should not effect your uploaded content, merely clear the local cache on the phone freeing up that /datadata space.
Hope this sheds some light on the issue for you, and how you can avoid it or remedy it going down the road.

Hi there! I have an Android based set top box and I'm looking for buying a sdcard so I could bring more space to it. The thing is I don't know which method should I use between apps2sd or external2internal so I have more space to install big games. Actually it has a little more than 5gb of internal memory, which is very poor if I want to install few games, emulators with its rooms etc.
Nobody? Up!
If your android version is grater than 2.1.x you could just go to settings->aplications and move the apps to the sd, if not you can use the apps2sd
It's apples and oranges. a2sd is very limited and only moves a part of the apk but not the other data of the app which takes up more space than the apk typically. External2internal does the whole SD card so you'll have as much storage as your card has space on it.

I was asking this because although I'm on 4.2 there's no a2sd support. Anyway, with apps2sd I was referring to Darktremor's script, which moves data to an external ext3/4 partition in sdcard, versus external2internal thing.
I've installed ext2int but I don't know how to configure it because I can't figure out internal mount point. I think it's using fuse.
