[Cuestion] Swap Partition on CyanogenMod 7.2

I tried every way, but I can not use the swap partition on my WFS.
I installed the latest version of the ROM and the Kernel, but I can't make it work.
Does anyone know what should I do to run the "Swap Partition" on my phone?

Go through this.
http://wiki.cyanogenmod.com/wiki/Swap_and_Compcache
The cyanogenmod team feels that swap doesn't serve it's purpose on an Android device. To quote them
"This question is hotly debated, but you almost definitely do not need swap or compcache. The only exception to this may be if the device is a first generation device (i.e. HTC Dream or HTC Magic). If you think swap or compcache may make the device faster, feel free to follow the directions below."

And the WFS is not a first generation device
If you still want to go ahead with it, that link provides a how-to.

But the problem is that with this ROM my phone does not recognize the swap partition. I would like to post on its own thread, but I can not because I am a new user.

You have to create a mount script and copy it to /system/etc/init.d and give it the same permissions all the other files in init.d
Attached is the code to use if you have swap as the third partition on your SD card. Remove the .txt extension and place it in /system/etc/init.d and give it the appropriate permissions then reboot
Use the command "free" in a terminal session to verify swap is active and working.
It should be pretty straightforward to modify it to be the second if you aren't using an SD Ext partition for programs.
The code is:
Code:
#!/system/bin/sh
#Checks for a swap partition on mount 3 of the SD card and use it for swap partition.
if [ -b /dev/block/mmcblk0p3 ];
then
#Uncomment the line below to adjust swappiness. Default is 60 I believe
# echo 20 > /proc/sys/vm/swappiness;
swapon /dev/block/mmcblk0p3;
fi;
Change the line:
if [ -b /dev/block/mmcblk0p3 ];
to
if [ -b /dev/block/mmcblk0p2 ];
If you only have your FAT32 Primary and your Swap partition and no SDExt

I will try it this evening. Some people told me that oboe is that I created the Swap Partition with the recovery and I have to create it with the PC.
If I get it working I'll post my results. If not you will see me here again.

When I try to move the script to the specific file I get: failed to copy, or failed to move. How could I copy or move the script in /system/etc/init.d and give all permissions? I am using ES File Explorer and ASTRO. Should I move the zipped file or only the script? I couldn't move none of them

You have to mount system partition as RW to be able to manipulate with files there, big white button "Mounr R/W" in the upper part of the Root explorer app while you are in /system/etc/init.d folder. Then you put there swap.txt file that d33ps1x provided up in the post, rename it just to swap and reboot phone.
I did that with almost every version of cm7 from the begining (in which kernel allowed that) and every time it worked, tnx to d33ps1x

Then the problem can be with kernel on ROM you are using, basic thing is that kernel needs to be abble to support swap for swap to even work... Can't help you much there since you are probably on marvelc version according to you'r country flag, i'm on diferent version. Some1 with same model as yours could help you tough

Is there any way to install another ROM that support swap? which ROM should I use? is there any tutorial?

The [2nd] above post is correct. Swap support is enabled in some custom kernels. If you're looking for another ROM, you're going to primarily ask about the kernel included with that ROM. Stock kernels do NOT support swap. You can enable swap [if you have a supporting kernel] via A2SDGUI or terminal... read up and familiarize yourself with linux swap.. since Android is a branch of Linux; same principles apply

This says it's possible to enable swap and compcache on CM7.2, but the howto wiki link is dead
To answer you question directly, by default the swap and Compcache schemes are disabled, but if you still feel the need to use them, above link provides you with a how-to.
So, yes, the CyanogenMod 7.2 supports swap and its usage needs to be activated.

For me the same question. I'm investigating since 1 week, tried scripts etc. no chance
Nexus One,
4EXT recovery (needed for correct sd-ext formatting)

swap partition is there but not used.
What could i do to enable the swap partition?

Hello,
I have the stable release cyanogenmod 7.2.0.
Swap is not working and gives following message:
swapon: /dev/block/mmcblk0p3: Function not implement
I found some notes saying that the problem is the kernel not supporting
swap. Which kernel can I use with cyanogenmod 7.2.0 with swap support?.
Thanks for your help.

[Q] Any way to change Thumbnail directory or decrease the size?

My thumbnail exploded to 707 MB and that's taking lost of spaces on internal SDcard
is there anything I can do to move the directory to External SDcard or resize it?

700 is a huge size, too huge for a thumbnail... At least for a normal one.
Thumbnail stores preview files such as those in your gallery or media player.
Its not recommended to modify the thumbnail anyhow.
But you can delete it if you want to.
I suspect its a mutated thumbnail. It means you got virus in it.
Try to scan it, if it doesn't go away, delete it. deleting thumbnails wont damage anything anyhow.
But just to be safe, you can always backup before doing it.

iv experienced this too when iv flashed the aokp JB long time ago( the very 1st aokp JB).n the size keep increasing.did delete the content but it keep coming back.did delete the whole folder but then the sd card still showed full memory.didnt know whats the prob.n same as OP i reverted back to my old ROM..mayb didnt do the pristine method when flashing(at that time i didnt know bout pristine)..

Use CM9 aka ICS based ROM. That was most likely one of the bugs remaining in CM10.
Though its true somehow instead of refreshing it accumulates.

will the result be the same?

But then I found another .thumbnail folder in root folder, and I think it is for movie coz I found "Oppa Gangnam Style" in it .
so is the command work for this thumbnail too by changing the directory to
cd /sdcard/.thumbnails?
Btw, what is the reverse command for this? coz i'm not really sure that it work as I wish, I remember the thumbnail folder exploded 1.35gb and my available memory is 2.++gb. after the command, the thumbnail get zero but my available memory is still 2.27gb. so i need the reverse command to compare.
sorry for my english, hope you can understand.

Have you rebooted? Due to the way Linux works, you can delete -- or zero, in this case -- a file, but the space used won't be released until anything holding that file open have closed. A reboot closes all processes holding a file, thus releasing back the used space.
To reverse the command, run the command again, but change 055 to 075 (the original flags for the file).
I'm not sure about /sdcard/.thumbnails ; I don't see one in my SD Card... what video player are you using? Maybe it belongs to that app...

After i rebooted, the .thumbnails files went down to zero. But after i took a video n pic with d stock camera app, it created another .thumbnails file! So now there's one file with 0kb and another a huge size. What should i do now? M on cm10 alpha6.

[Q] byte 4byte forensic image of Galaxy w

Hi
I have a rooted Galaxy w and I am looking for a non commercial app that can make a byte for byte forensic dd image of the phone.
I want to do this so I can look for detailed SMS messages using winhex.
I wonder if anyone can suggest such an app but I'd prefer one that does not need complicated command line input as this just confuses the heck out of me.
Also, I have seen on various forensic sites reference is made to files named mtd0 through to mtd5 but when if have searched through
My galaxy w, these files are not on it anywhere?
I apologise if you are sick of this kind of question but any guidance or advice would be much appreciated.
Thanks in advance.

It will take only 5 lines of commands actually, and if you use adb shell instead of Terminal, a very easy copy-and-paste.
Code:
su
targ=/mnt/external_sd
bsiz=$((1024*1024))
blkp=/dev/block/mmcblk0p
dd if=${blkp}17 of=$targ/data.img bs=$bsiz
dd if=${blkp}28 of=$targ/internalsd.img bs=$bsiz
Just modify the "targ=" line to point to your location of external SD (will be 'sdcard' instead of 'external_sd' if you have swapped the SD Cards).

Yes, because it reads from the 'raw device', so each and every single byte, be them living in a used sector or a 'free' sector, will be copied. Up to and including the very last byte in the source partition.

[Q] Symlink from /sdcard to /storage/extSdCard

Hi
I'm trying to use a symlink from the internal SD card to the external one so I can use WikiDroyd on a larger disk. I have done this before to map google music to my extSDcard and it works great, using this command
ln -s /storage/extSdCard/googleMusic/ /data/data/com.google.android.music/files/music
but when I try
ln -s /storage/extSdCard/WikiDroyd/ /storage/emulated/0/WikiDroyd
I get Function not implemented. I'm guessing it's because /storage/emulated/0 doesn't support symlinks, is this because of it's disk format? Does anyone know how to find out it's format? Can I reformat it?
Note: I am using omega rom

Is /storage/emulated/0 the default directory for the app? If so, it may be failing due to trying to replace an existing directory with a symlink (particularly if that pre-existing directory is in use at the time).
If the app's directory setting can be altered, why not try putting the symlink elsewhere? Even if the app doesn't let you set a custom directory, creating your symlink elsewhere would, if successful, narrow down the likely causes of the error (unfortunately, if the app's directory setting is hard coded out otherwise unchangeable, then it would also prove that what you want to do is not possible, at least not through this approach)

Are you sure that ln -s will work on non ext partitions? I don't think this won't work on FAT32/NTFS partitions.

That's a good point, I thought that certain configurations might work (like placing the link on an ext partition that points to a file on a fat 32 partition, since Linux can read both and Windows would never see the Linux-style link, for example) but I'll double check...

[GUIDE][HOW-TO]Use SWAP As Virtual RAM Without Partitioning SD Card

Firstly what is swap, you should know about it before
you go further
What is Swap:-
Swap space in Linux is used when the amount of
physical memory (RAM) is full. If the system needs
more memory resources and the RAM is full, inactive
pages in memory are moved to the swap space. While
swap space can help machines with a small amount of
RAM, it should not be considered a replacement for
more RAM. Swap space is located on hard drives, which
have a slower access time than physical memory.
Swap space can be a dedicated swap partition, a swap
file, or a combination of swap partitions and swap files.
Normally the swap space should be equal to the Actual
physical Ram

Requirements for this process:-
* Kernel which supports swap(Deviant,Hells,GNU,Merruk)etc
* Rooted galaxy y
* Busybox (atleast v1.18)
* Terminal Emulator
Click to expand...
Click to collapse
Steps to enable swap:-
1. Open any file explorer(I prefer root explorer) and create a folder and name
it swap
2. Browse to that folder and create a file named swap
3. Open terminal Emulator and type the code busybox
mkswap /sdcard/swap/swap xxxxxx
(xxxxxx is the amount in KB, eg:- 383456 = 378MB),
and this process will take time.)
4. Now we will activate the swap and to activate it type
in terminal busybox swapon /sdcard/swap/swap
5. The last step is to turn on swappiness and to do it
we write echo 100 > /proc/sys/vm/swappiness in
terminal
And now you are done to check the working of swap
type busybox free in terminal emulator.
NOTE-Last two steps are needed to be done after every boot
so it is better to make a script which can be started
from script manager......... and here is a script ready for this Swap.sh

Tick "Safe Unmount" and "Safe Remount", u dont need
to turn off or turn on again before and after sharing sd
IMPORTANT!! :
go to Advanced preferences -> untick "Recreate
swap file" and "Reformat swap" MUST!!

yes I know friend but partition or not you have to create a swap folder in sd card which serves as a virtual partition

bro apps are not the same like ram,google for more infos.

Or do a xda search

yes I know sir but iam not saying about the apps ok lets make it clear by using your method we create a folder named swap in the sdcard and it serves as a virtual rom right??
and I was only saying that as caliban666 said continuos read and write in sdcard will decrease its life whether it is a partion or a folder
