Swap partition?

Should I partition my SD card with a Swap partition? Do I have any gain from this?
If yes, what size should the Swap be? I have a 16GB class 6 SD card.
I usually partition my sd card with 0 swap and 1gb sd-ext size.

I've tried to use this for link2sd work but no success
Tried using swap,two fat32,ext2-ext3-ext4,well...
Always fail.

Link2SD has nothing to do with the swap partition.

In this case,no. (p970)
Galaxy 5 yes,to "bypass" the system restriction.

Did I post this thread in the Galaxy 5 forum? No.

It's just an example,Mr Bad Mood...

[Q] Swap Area / EXT2 partitions - Help needed.

Hello, I'm hoping someone can answer a few questions I have regarding the format of the SD Card for the Android system. - Apologies if this has already been explained on this forum, I did a search but didn't find anything too useful that answered my questions.
(I have knowledge of the linux file-system and swap drives, just unsure of the benifits of this for android).
Currently using a 16GB SanDisk Class4 SD Card.
I'm aware that you can format the SD Card to use as a swap-drive and for use of ext2 file-system.
While searching for info on this I found the following xda link which simply explains how to do this:
http://forum.xda-developers.com/wiki/SD_card_partitioning
My questions are:
1. What are the benifits of having the ext2 file-system? (Would apps stored on SD Card run faster etc?)
2. Do I need to keep a FAT32 partition (as opposed to just having a swap and ext2 partitions without any FAT partition).
3. Does the swap drive greatly improve performance. And is this worth doing on a Class4 SD Card?
Thanks in advance!

Hi.
at the first I must say swat will decrease SD card life.
i recommond you to create EXT3 or EXT4 partition.
1)one of the benefit of EXT partition is your phone storage will not full and its help your phone performance.
2)yes.of course you should have fat32 partition for eg:music-movies...and other files.
3)yes.swap is a very good.and it helps your phone ram.eg:when you play plants vs zombie at the first screen game will exit because of ram and swap will use like ram and its good for gaming.

Thanks for the reply, much apprecaited.
Are you sure I need a FAT32 partition though? Videos, music etc etc can all be saved to ext2/3/4 on a linux OS so I just assumed I could just do away with FAT32 all together?
Is the following just not the same as using an App2SD app?
"1)one of the benefit of EXT partition is your phone storage will not full and its help your phone performance."
Sorry for being a bit fussy but I'd like to fully understand what the Ext/2/3/4 partition is actually used for. Is it just used purely for storage?
Thanks again!

In a short summary (and assuming you are using a Kernel and ROM supporting the features) ...
- "Swap" on a swap partition has its own own "filesystem". The data structures are actually created by "mkswap" and the partition is not directly accessible by the user. If your phone runs low on physical memory unused parts of the memory will be swapped out into the virtual memory to make room for other apps.
Note that this is no "magically increase your RAM" solution. Once swapping occurs it actually slows down the system as the swapped out memory regions need to be copied back into physical memory, sooner or later. It may only help to run "RAM hungry" applications.
- "SD-Ext" is a, most likely, ext2 formatted partition to where Apps you move to the SD (either by Android or App2SD) will go. This increases the amount of apps you can possibly install, but doesn't resolve the problem that apps having widgets or apps that are started during Android boot-up need to reside in the internal phone memory.
- The /sdcard partition where all your user data is being stored should be kept FAT32 (for the simple reason of making a backup of your data by slapping the card into card reader easier - Windows can't read Linux filesystems by default). Some ROMs will allow you to format /sdcard ext3 or ext4 ... the advantage is that ext3/4 (if the mount options are correctly set) may perform a lot better than FAT32, though your mileage may vary.
Roger? ...or do is something still unclear?

Many thanks B.Jay - I'll hit the thanks button after I post this reply! You cleared up all my questions, but just going back to the FAT32 partition;
I use linux as my main OS, so accessing the EXT format partition wouldn't be a problem; Do you know if all ROMs would work without a FAT32 partition and replace it with EXT2/3/4 partition? If you're unsure I can always find out by formatting and loading a rom.
Thanks again, you've been most helpful!

Linux would, of course, be able to mount a ext partition (even on a SD card put into a card reader).
As for the ROM ... it depends.
The Stock Kernel Modules AddOn of GingerDX introduces ext3 and ext4 modules for the SEMC Stock Kernel, so in theory (I didn't test it!) you should be able to access /sdcard when being formatted ext3/4 - though it could be that you might need to adjust the vold script to properly mount the partition. The modules are mainly for supporting the sd-ext partition for "Apps-to-ext3/4-partition-on-mSD".
There's also alfsamsung's Alfs Kernel which is compatible with GingerDX and some other ROMs. That would be something you could try as well.
Simply look through the ROM threads ... I think MiniCM7 (+nAa's Kernel) should be able to support it, though this could involve some tinkering.
Personally speaking, I only have a ~2GB sd-ext on the SD in my X8 and the rest is a normal FAT32 partition (/sdcard).

yes you need a FAT32 partition.
when you partition your SD card you can move moveable app and games to ext partition.
please dont move app wich they cant move to ext partition.
cause after restart app that you moved to ext will corrupted.
good luck.

Thanks again! I think I'll follow your trend and try the 2GB SD-ext and the rest FAT32.

sd-ext missing!!
hey guys!! I've a small prob, would appreciate some tips. I normally move apps to sd card, if the app is movable by default. if the app is not movable by default, i use this app2sd by droidsail (available in the market) which force moves parts of the app 2 sd card. When I make back ups using xrecovery, i have no problem.
but when I use cwm for back ups, it gives an error saying sd-ext not found and it skips that part of the back up!! so any app I've moved by default or forced moved to sd card doesn't get backed up!! So I presume I have to create a sd-ext partition manually? How do I do it? I do have an sd-ext folder. but its not in sd card. it's in the root. (never had this prob with xrecovery though)
thanks in advance!!

[Q]Swap and app2sd

Hi!
Could You give me tutorial how to make swap and app2sd on SDE?
I think I have to make partitions. First with swap. And now one partition ext4 and there will be app2sd and my files or two partitions-first with app2sd and second with my files?
My card is 10class and 8gb
Thanks

Please, tell me what is your sd class and how much gb have it?

8gb and 10class
Thanks

1. FAT32 (for you own files - music, pictures etc.)
2. ext4
3. swap
create them in this order.

cwm can do that.
format sd
create partition
swap....
wait...reboot
in terminal emulator.
type
su
a2sd xdata
y
y
enjoy.

To make partitions on your SD follow these steps.
1.Make a backup of your SD.
2.Enter CWM recovery.
3.Go to advanced->Partition SD card.
Now it will ask you for sizes of A2SD and SWAP.
Set them as you want.
Its Done...
NOTEartitioning the SD will erase all the data on your SD card..

Difference between Link2SD and Apps2SD
Hi Guys,
I just wanted know the difference between Link2SD and Apps2SD.
When I used Apps2SD all my user application are moved automatically to SD Card. I don't have a choice to select the app to be moved to SD.
where in in Link 2Sd I have an option to move selectively.
more over when tried apps2sd on ICS ROM ( MiniCM9.0.4 ) it wont work. many forums says the apps2sd scripts are not supported in ICS due to changes of implementation of OS.
so which one is better ? why ?
Secondly which iotion is beeter for swap ?
Swap partition or Swap File
1. I know Swap partition allows to use even if phone is connected to PC where as swapfile will dismounted if you connect ot PC.
but if I use ReadaheadKB setting of SD card in devices section swap file will perform more faster ( as it was cached partially) vs. swap partion
( ReadAheadKB helps to perform sequential reads more faster )
even if SD card wear & tear is more with SD card. th cost for SD cards are down so drastically that one can afford the loss of SD card ( laugh: data on SD should be backed up frequently :laugh:
Cheers!

[Q] My 32GB SD will not partion

I am currently using the cyanogenMod 10.1 (4.2.1) kernel version 2.6.37.6-jellybean+ [email protected] #2.
I tired to partition my 32gb sd card by 4gb. After i partitoned it and went to settings and storage a seen that a 25gb in external memory but will only 178mb in internal memory why is my partition not working and could anyone tell me how to get it to work please. Partitioned it by using clock mod recovery v5

Hi you must install link2sd app
Only partition sdcard doesn`t work the app creat a script to init.d folder and cwm 5 partitioned sdcard only to ext3, if you want ext4 use px recovery or on windows magic partition manager with sdcard reader on other side there are scripts like to amarullz script or cronmod which "increase"internal memory but they doesn't work at now

[Q] Using sd card for internal and external storage

As we all know the android one comes with limited internal storage storage and media (pics,documents,videos) can only be stored on the external sdcard. On the forum there are various methods to swap storage size , however on doing so storage space for media will be limited to fixed 2 gb space currently available for internal storage. I was wondering if it is possible to partition a 32gb class 10 sd card and use 16 gb each for external and internal storage. I wouldn't mind if the internal phone storage would have to be abandoned in doing so.
Has any one successfully done this..
'

Yes you can do that using link2sd.

Check this out.
I have made a 4GB ext4 partition on my 16GB sd card and I keep all my apps stored in the 4GB partition. And 10GB is kept as media storage.

Could u please specify how to do it properly for lollipop devices.. there are many in the forum and some run into performance issue if not done properly.

Here it goes.

So download the zip file from the attachment. You will find link2sd app and a patcher that makes the app link2sd plus and is totally functional... And other things about link2sd is nicely explained in this site, https://awanstuff.wordpress.com/201...ink2sd-in-any-android-phone-with-screenshots/ Just keep in mind to create a ext4 partition instead of ext2 and you are good to go. And I would suggest you to use high speed sd cards preferably class 10 and higher if you want a smooth experience on your lollipop rom. I use class 10 ultra from sandisk. And my apps run buttery smooth...

Has anyone tried link2sd on lollipop .some saying it doesn't play well because of some changes in how lollipop stores app.

Works perfectly.

I'm using it on my lollipop 5.1 and it works flawlessly...no hiccups at all... Why don't you try it for your self and find out...

I tried partitioning and also installed link2sd plus but it does not recognise the partition, it still says unable to create the mount, it resets the link on every boot.
I have Class 4 SD card. Will it be okay if I used it?

I am also using class 4 sd card, it is working fine. Have you formated one partition in FAT32 and another in EXT4
