[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.

Any idea how to do this?

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)
CM 7.2
swap partition is there but not used.
What could i do to enable the swap partition?
Regards,
Marc

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.

[Guide]Use swap as virtual ram without partitioning sdcard

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!!

Guide # LAVA IRIS 402 / 356 # Increase RAM and Internal Memory

1. Root Lava Iris 402 / 356 by Framaroot
Select the Framaroot 1.6.1.apk in the below link from your opera mini browser – select save – select open and select install.
http://forum.xda-developers.com/showthread.php?t=2130276
Thanks Alephzain
In Framaroot → select Boromir. After success message reboot your phone.
Now you have Root access.
2. Install Busybox
Go to Playstore and Install Busybox by Stephen (Stericson)
Open Busybox give root permission when prompted.
Wait for few minutes to complete smart install analysis, then select install then select smart install without making any changes.
Busybox is needed for executing modifying commands.
3. Increasing Internal Memory for installing more apps
Make 2 partitions in your SD Card as primary partitions using minitool partition wizard in windows / gparted in linux (be careful to change only sd card and not computer partition)
1st as FAT32 (primary) for storing DATA, Music, Videos etc.,. (say 6.5 GB in 8GB SD Card)
2nd as FAT32 or ext4 (as primary) for linking apps with link2sd – balance memory in sd card (note: kernel supports ext partitions)
You can also resize partition. See link below on how to partition
http://forum.xda-developers.com/showthread.php?t=2142844
Thanks bakpinar and sanny5
Install Link2SD from Play store → select Fat16/32
→ if it says mount script created. You can link your apps to 2nd partition through link2sd.
→ If it says mount: no such file or directory –
Install Mount /System (rw / ro) and ES File Explorer from Playstore.
Select Mount R/W in Mount /System app.
Copy the below script in notepad++ in windows (not notepad, google it)
or gedit in linux
or download the file posted by raveesh84 for fat32 partition in 7th post below
or if you want to type using your phone install droideditfree
and save as install-recovery.sh and copy the file to the folder /system/etc/ (after enabling Mount r/w as said above)
--------------------------------------------------------------------------------------------
#!/system/bin/sh
# mount vfat 2nd partition from sd card
sleep 2
mount -t vfat -o rw /dev/block/vold/179:2 /data/sdext2
mount -t vfat -o rw /dev/block/mmcblk0p2 /data/sdext2
---------------------------------------------------------------------------------------------
Note : Replace vfat with ext4 in the above script if you want to use ext4 partition.
Read the above script horizontally in phone.
Thanks to Kierrok
Note: Copying and permission setting will happen only after Mount R/w.
Permission setting for the above file -> Enable Root explorer to ON in es file explorer by going to menu --> tools --> root explorer ON. Then long press the copied file in ES file Explorer -> select more -> select properties -> select change under permissions -> tick all the read, write and execute except write by others.
Reboot phone. Link2sd will work now. Link apps, don't create mount scripts.
Note:
1. Install big apps first and link all 3 files in it, otherwise small apps take space in internal memory & will not allow installation / linking of big apps.
2. If you restart your phone you might get low space error, immediately open link2sd - sort apps by lib size - select top 5 or 6 six apps one by one and link the lib file (link vanished due to restart). Space error will go.
4. Increasing RAM (SWAP)
The phone already has 190Mb internal swap. It is too low.
Install Swapper for Root → put value 756 → select active at boot. Class 10 sd card will work better.
You can also further increase SD Card speed with installing SD Speed Increase → setting kbs based on class of sdcard to maximum
and set on every boot.
Now we have overcome the twin limitations of LAVA IRIS 402 to some extent.

Class 10 sdcard would perform better for swap, also increase sd card speed.

Useful apps for lava 402 / 356
-------------------------------
Android firewall - restricting which app to access internet in WiFi or mobile data. (Enable mediaserver and download manager for tube mate and play store to work respectively. Also enable android related things to WiFi and / or DATA, will be useful in case of lock due to wrong patterns)
Greenify - making apps that you are not working on to sleep
Tubemate (from opera app store) - to view or download YouTube videos in lesser data, 320x240 resolution would be good enough.

Thanks for the guide. Worked perfectly on my lava iris 356.

Dear sir,
I wish to start with my thanks about your internal memory upgrading blog.
I have purchased new Lava 402 Smart Phone. I am getting message as "the phone storage does not have enough space. please release some storage or change the default write disk in the settings" while using camera. But I checked in my mobile settings, there is no option to change the default memory settings to write in SD Card. Please help to come over from this issue.

I didn't had any problem with camera. It is storing images to SD card only. Has your SD card detected ? Re insert card properly after switch off. If this also not works try installing any other camera app from play store.

You can also further increase SD Card speed with installing SD Speed Increase → setting kbs based on class of sdcard to maximum
and set on every boot.
Now we have overcome the twin limitations of LAVA IRIS 402 to some extent.

Both are working, tested. Revived phone from Bootloop (tried to install cwm recovery through mtk droid tools 2.4.8 version not supporting mt6572)
Above information have been searched / collected by me from various threads / sites for the benefit of lava iris 402 / 356 users.
Note : Though above have been tweaked by me in my Lava Iris 402 and it is working well, I am not responsible if anything goes wrong.

The above mentioned script didn't work in my case. Did exactly as explained in my IRIS 356 Phone. After the restart phone got stuck at the logo. Must be something must have gone wrong. Had to remove SD card to boot phone properly. Any suggestions???

I have a Lava Iris 402.. Link2SD fails to detect the second partition in both cases (FAT32/ext4). Any solution??
Copy pasted the script in /system/etc. Link2SD still doesnt detect 2nd partition.

Have you set the permission for the copied file as explained ? It should work if it is done.

If you had done as explained it should work. It takes initially a minute to boot after the script copying, can you wait & check if it is OK.

Set the permissions as mentioned in the OP. Ticked all Read, Write & Execute, except Write (Other). Is that correct?

[Q] rooted - root explorer not copying some dirs

SM-T705, cf-autoroot (incl. SuperSU) checked with root-checker, platform.xml adapted
e.g. if I want to copy /dev to my sdcard ... there comes a message similar to "copying went wrong ... 4.4+ .... in non-root mode some limitations ..."

I won't search for you, please have a read through Q&A and General for a number of other similar questions and corresponding answer I would suggest you please contact a Mod to delete this unneeded thread

Sorry I searched and read a lot of older suggestions but did not get a clue ... and I know about the kitkat probs regarding SD (platform.xml). But still dont understand, why there are just few folders affected ...
So sorry but it seem I need a Little push into the right direction

+1 solid explorer has struggled for me, but root explorer hasn't. Seems to be only certain directories. ...idk

just to make shure - we are talking about Root Explorer (File Manager) non free app. Did you try to copy System dirs like /dev ??
if yes, where to did you copy them. I just figured out that my ext3 partition (1st=exFat, 2nd=ext3) on the SD is mounted to /data/sdext2.
but copying /dev to /data/sdext2 doesnt work either

Could someone please tell me how to Mount /mnt RW

some folder cant be copy. the only way for you to have those are extracting it from the original firmware.

THX - 2 Pprobs now
1
mount -o remount rw /System worked, but still
[email protected]:/ # mkdir /mnt/extSD2
mkdir failed for /mnt/extSD2, Read-only file System
a) with Root Explorer it seemed to work, but was gone after restart ?
b) where to mount my ext3 SDcard partition (1st exfat, 2nd ext3)
c) can I do it by modifying init.rc, universal5420.rc or fstab.goldfish ...
2 how to extract Folders from Firmware files like T705XXU1ANF7_T705DBT1ANF1_T705XXU1ANF7_HOME.tar
I extracted the files within. But how can I Mount those Image files on W8 (ext2fs does not work with my sdcard) ?
2nd best would be to go to my Linux PC (but I'm a Linux DAU) ...

try learn about kitchen or use this software on windows... ^_^ http://sourceforge.net/projects/ext2read/

sorry my english is not good enough ... kitchen seems to be a Linux tool ... this seems to be a good start http://www.modaco.com/topic/366230-tools-useful-tools-for-tinkerers/ or this http://www.diskinternals.com/linux-reader/
Best use OSFMount to Mount the *.img and "Paragon ExtFS for Windows" to view the files

mount -o remount rw /System worked, but still
[email protected]:/ # mkdir /mnt/extSD2
mkdir failed for /mnt/extSD2, Read-only file System
a) with Root Explorer it seemed to work, but was gone after restart ?
b) where to mount my ext3 SDcard partition (1st exfat, 2nd ext3)
c) can I do it by modifying init.rc, universal5420.rc or fstab.goldfish ...

mounting system.img does not work

How to swap internal storage with the SD card in Nokia x
Step 1: We need a rooted phone for this process, if your phone is not rooted then first of all root your phone.
After root your phone, install root file manager. You have two options: 1. Root file explorer app, 2. Es file explorer file manager
Step 2: Open the Root explorer app >>> then go to root folder >>> then find and tap on the system folder >>> Now you can see the ETC folder, open this folder >>> after then you will see a list of files and folder, Now find vold.fstab >>> tap on this file, you will get lot’s of option, now tap on text editor option.
Step 3: After tap on the text editor, you will get a popup tab from Su app for giving root permission to root explorer app >>> tap on the grant option >>> then you will get a warning message for remount as read-write then tap on yes.
Step 4: Now vold.fstab file open for you, find these two line in this file:
dev_mount sdcard /storage/sdcard0 [email protected] /…………
dev_mount sdcard2 /storage/sdcard1 auto /…………….
You can see these lines in this image. Not much to do here, just change sdcard0 with sdcard1 in the first line and sdcard1 with sdcard0 in the second line >>> Now tap on the menu button in the phone >>> and tap on save and exit >>> close root file explorer app and reboot your phone or device. that’s all.
