I made this Tutorial for enable ext and swap partition.
I have based this guide on:
- sdparted script (thanks to 51dusty): i modified the script for works on our X8
- on http://forum.cyanogenmod.com (Enabling swap)
Requirements:
- AlfsKernel (i used v03 for this tutorial)
- GDX (i used V019 for this tutorial)
- ADB
- sdcard (i used SD 8GB class 4 -> recomended class 6)
Click to expand...
Click to collapse
My configuration: (with SD 8GB class 4)
- fat32 -> 7040 MB
- ext3 -> 1024 MB
- swap -> 128 MB (swappiness 100)
Click to expand...
Click to collapse
Instructions:
1) download sdparted.txt and userinit.txt below to root of sdcard
2) boot into CWM recovery
3) mount /sdcard, /sd-ext (if you have ext partition) and /system
4) backup sdcard: adb pull /sdcard/ sdbackup
5) If you have ext partition and you want backup this: adb pull /sd-ext/ sdextbackup
6) run: adb shell
7) move sdparted.txt to /sbin -> mv /sdcard/sdparted.txt /sbin/sdparted
8) then, chmod 755 /sbin/sdparted
9) run sdparted: for the differents options see the original thread
This is for my configuration -> sdparted -es 1024M -ss 128M -efs ext3
10) restore sdcard backup: adb push sdbackup /sdcard
11) restore sd-ext backup( if necessary): adb push sxtbackup /sd-ext
12) move userinit.sh to /sd-ext -> mv /sdcard/userinit.txt /sd-ext/userinit.sh
13) then, chmod 755 /sd-ext/userinit.sh
14) reboot

Click to collapse
Note:
For change swappiness, you must edit userinit.txt before of copy this to sdcard. You must modified line 12 with the value you want:
echo 100 > /proc/sys/vm/swappiness;

exactly what is this swapper for??
i've never used it before
here
make google as your friend..
i use swapper 2 with swap partition and is working perfectly.
i have a swap partition with 128mb,ext 3 with 512mb and the rest in fat32.
my sdcard is a kingston 4gb class 4.

With this, you don't need any app.
This is another option for use swap taking advantages of the kernel, and i think that some users don't know.

ok.i only say that because swapper 2 its noob friendly.
Hi dev,
Just ask questions, what is swapiness?
Whats wrong if swapiness set to higher value or lower value?

you can see this http://en.wikipedia.org/wiki/Swappiness
After some test, for me, the best performance is 100; but for some people is 80. You must test it in your phone with your configuration and apps.
For change it and test without reboot, you can type in console: sysctl -w vm.swappiness=0

anyone experienced any performance improvements after enabling swap?
i can notice in games that slowed down sometimes. On the rest i can't notice anything at least for now.
and i have swapiness set to 80.
Nice tutorial, I have question :
1. Can I install it with terminal emulator or script manager?
2. When I want to change kernel (alf's kernel to LDX), is it need re-setting (re-install) or not?

I googled a bit, and "they've" said that the newer CWM could be the problem, it's not fully compatible to all SDCARDs. (mine is a Class6 8Gigs)

I'm trying to make an auto install script within the initramfs. I've got everything working, including automatic fdisk, but I cannot get mkfs.ext4 to work on the Android kernel, and there is no version of Busybox with the ext4 applet. Does anyone have a mkfs.ext4 that runs successfully on Android? When I run it from a terminal the output is
Code:
mkfs.ext4: 1: Syntax error: word unexpected (expecting ")")
Here's my code if you want to see what I'm doing.
Code:
mount /dev/mmcblk1p1 /tmp/mnt
if [ -f /tmp/mnt/mysticfw.tar.gz ]; then
$FDISK /dev/mmcblk0 < /home/fdisk.input
$MKFS_EXT4 -O ^huge_file /dev/mmcblk0p2
mount /dev/mmcblk1p2 /tmp/tmproot
mkdir /tmp/tmproot/itworks
tar -xzvf /tmp/mnt/mysticfw.tar.gz -C /tmp/tmproot/
sync
#rm /tmp/mnt/mysticfw.tar.gz
umount /tmp/tmproot
fi
sync
umount /tmp/mnt
It automatically partitions the stock Android block and installs a tar.gz from the internal storage to simplify my unsquashed 2.1.4 filesystem install, and the only part I can't get working is mkfs.ext4.
Found one! It's 3 MBs though, so if anyone has a smaller one, it would be very nice.

Why didn't I think of that? Thanks.
But regarding mmcblk0/1, I'm replacing the stock Android, so the fdisk.input file contains the commands to delete mmcblk0p2 and p3, and make a new partition in the unused space. I hate using space on my Internal Storage, so I'm using Archos' space.

If you are using the mmcblk0p2 as rootfs as you say (and you are expanded tar archive on mmcblk1p2), than you have to change the line:

I know, that's my current data partition, I'll change it once I'm done testing. The tar file just has a test file in it, so when I boot back into block1, I can see if the IF statement was executed by seeing if it was extracted to block1. I'll also have to change etc/mountpoints once testing is actually finished.
One more question since you're so quick. I think I have everything working, except it needs a reboot in between the fdisk and mke2fs commands to reload the partition table. I'm trying to use partprobe instead of rebooting, but it hasn't been cross compiled to work on Android, AFAIK. Have you seen a way to reload the MBR without rebooting?

I'v been looking at the recovery_lib.sh in the recovery boot image and can't find anything special to re-read the partition table. And yes they also use fdisk to repartition. So I suspect the driver for the block device does not cache the MBR and you can just mke2fs after the partition table is created.
I can't remember from what firmware that recovery boot image was but I think it's from the 2.1.04 and they do some repartitioning there for the swap space.
I'll check it again and get back to you.

I just checked the recovery image from 2.1.04 and after the fdisk commands there is nothing to re-read the MBR the next commands executed are mount commands to check if the fs is present I suggest you look at the /etc/scripts/recovery_lib.sh yourself it could give some clues on how to do things.

For me too, it have nothing to do with a reboot to load partitions table and access partition to format them with the choised filesystem.
You can delete any partition on linux (except rootfs one ), recreate them and directly format them as you like, reboot isn't necesary.
Thanks for all the replies, very helpful, but I'm stuck. Fdisk seems to use ioctl to reload the partition table, so you don't need a reboot if everything on the device is unmounted before writing the partition table, but I'm having very strange issues with mke2fs now. I've had the whole thing work twice now, but when I flash back to stock, then retry the script, it usually does everything except the formatting. Here's the code:
Code:
mount /dev/mmcblk1p1 /tmp/mnt
if [ -f /tmp/mnt/mysticfw.tar.gz ]; then
umount /dev/mmcblk0p1
umount /dev/mmcblk0p2
umount /dev/mmcblk0p3
umount /dev/mmcblk0p4
fdisk /dev/mmcblk0 < /home/fdisk.input
mv /tmp/mnt/mysticfw.tar.gz /tmp/mnt/mysticf.tar.gz
sync
umount /tmp/mnt
log_and_reboot
fi
if [ -f /tmp/mnt/mysticf.tar.gz ]; then
rm /etc/mtab
touch /etc/mtab
mke2fs -T ext4 -O ^huge_file /dev/mmcblk0p2
mount /dev/mmcblk0p2 /tmp/tmproot
tar -xzf /tmp/mnt/mysticf.tar.gz -C /tmp/tmproot/
sync
mv /tmp/mnt/mysticf.tar.gz /tmp/mnt/mysticdone.tar.gz
umount /tmp/tmproot
rm /etc/mtab
ln -s /proc/mounts /etc/mtab
fi
sync
umount /tmp/mnt
I have it reboot after the fdisk just in case, and the fdisk works perfectly, so the second IF/THEN is the issue. I had to retouch the mtab just to make sure it's empty, as mke2fs fails if mtab doesn't exist(at least in terminal), then I relink it to /proc/mounts as they do in the stock firmware. Here's my mke2fs.conf:
Code:
[defaults]
base_features = sparse_super,filetype,resize_inode,dir_index,ext_attr
blocksize = 4096
inode_size = 256

Simple append (">>") and "echo" doesn't work to a redirected logfile?
I've only learned what I've needed to learn over the years, usually with endless google searches and reading through man pages, so I've never tried to log outputs, because I could always see the output in a terminal or onscreen during boot. Android is the first time I haven't been able to actually see the boot process.
Once again, thanks for your help. I probably could've googled this, but I kind of asked as an afterthought. I didn't even think about redirecting. So if the mke2fs line is the one I want to log, I just add "2&>> /tmp/mnt/logfile" to the end of it, right?
Also, thanks for your original thread about booting from Internal Storage, I never got around to developing on Android until you posted that, and I realized just how similar Android is to L/unix(e.g. exactly the same).

ehm, no.
In your case must be like the following:
Code:
"your command" >> /tmp/mnt/logfile 2>&1
That means redirect all messages from STDERR (2 - standard error) to STDOUT (1 - standard output) and all messaged collected on STDOUT to the redirected log file /tmp/mnt/logfile, or more comprensible redirect all mesage including error ones to the log file.
I'm working in Unix environments and use them often
And a good practice in developing is to use "echo" to the same log file, so you know the exact place the script is running, like:
Code:
echo "I'm just before the formatting step of the ..." >> /tmp/mnt/logfile

Strange. The google searching lead me to believe the "2>&1" was before the location, and replaced ">>". Once again, thanks for the help.

I could probably finish it, but I'm waiting for a new version of Uruk first, as his install script already gets rid of the linux steps, it just doesn't give you the choice to install to the internal memory yet. Once he does that, I'll add my changes to make it install to the Archos partition. The latest Uruk is also a bit too big for the archos partition. I had to cut my data partition down to ~150 megs.

Specifically, what do I need to install on my gtab so that it can read an sdcard formatted to ext2?
I've already installed Clockworkmod and Vegan-Tab Ginger. Maybe I need a different kernel too? I know very little about kernels - Are they device specific? Are they interchangeable? Can I change the kernel without wiping my files?
Has anyone ever had success with ext2 on the gtab?

ext2/3/4 are all natively supported by the linux kernel, and issuing a mount command will work if you do it on the command line. However, the automounter program, called vold, likes to have ext4 or VFAT (aka FAT32) filesystems on the SD card. If your ext2 formatted SD card is not automatically mounted, format it again as ext4.
Formatted the sdcard to ext4, but still cannot read anything off it.
As for mounting through the terminal, if I use
fdisk -l
it shows nothing, not even an error. Is there another way to list disks so I know what to mount?
What I'm trying to do is use the Debian installer for Android, but the only version I could find is 2 years old. It's probably based on Lenny or earlier which does not have native ext4 support.

Edit:
If I insert a ext2 formatted sdcard, I get a notice that it is being scanned for errors. It goes away after a minute or so.
If I go to /sdcard2 in Root Explorer, the folder is empty but the stats show a correct 2 gb of used space and the correct amount of free space.
(Also in Root Explorer, if I try to create a test file, it says 'successful' but no file is created.)
If someone here owns a gtab and can access a ext2/4 sdcard, please let me know what setup/Rom you are using. Or if you own an extra sdcard you can format to ext2, and use some other aftermarket ROM/different kernel on your gtab, please test and post your results.
The commands I gave were just examples, you'll have to adjust them to suit your system.

That looks like the correct behaviour. The external SD card is being fsck'd and then automounted.

This, again, is correct, except that on a newly created filesystem, Root Explorer should've shown a lost+found directory.
(Also in Root Explorer, if I try to create a test file, it says 'successful' but no file is created.)

Reformat the filesystem again and try creating a file using the command line:
Code:
$ su
# echo test > /mnt/sdcard2/test.txt
# cat /mnt/sdcard2/test.txt
test

My external SD card is formatted as ext3 and I have no problem using Root Explorer. With other file managers, you'll have to be careful because of the standard Unix permissions that come into effect on all extn filesystems. If you want to use file managers other than Root Explorer, just create a new directory on your ext2 filesystem and give that directory a user of "system" and a group of "sdcard_rw", and give (at least) the group "rwx" permissions. Use the user, group and permissions of the /mnt/sdcard directory as a guide:
Code:
$ ls -ld /mnt/sdcard
d---rwxr-x 22 system sdcard_rw 8192 Jan 1 1970 /mnt/sdcard
$ su
# mkdir /mnt/sdcard2/user-dir
# chmod 0775 /mnt/sdcard2/user-dir [I]#or 0075 to exactly match /mnt/sdcard[/I]
# chown system.sdcard_rw /mnt/sdcard2/user-dir
If you don't want to bother with all this, just format the SD card as VFAT, and Android will automatically mount the VFAT filesystem with an owner of "system" and a group of "sdcard_rw". And since (all?) file managers belong to the "sdcard_rw" group, they get automatic read-write permissions to that filesystem. BTW, the Terminal Emulator app also belongs to the "sdcard_rw" group, so you can freely write onto VFAT formatted SD cards on the command line without resorting to the 'su' command (the example above).
Granted, it's been a while since I researched this - but I learned many months ago that the version of VOLD in Froyo does not support anything else but vFAT - so it just won't mount EXT2, or NTFS for that matter.
the mount command would bypass VOLD and we know that NTFS should work, if it's a custom kernel. Conceivably EXT2 should also work, but since it was all manual scripting I just stopped researching it - mainly because I'd still have issues using the card with other devices so it wouldn't really be a portable solution anymore.
As much as I detest FAT32 for its file size limitations, it's still the "standard" between portable devices. The various vendors have yet to figure out a replacement, since they can't seem to agree on anything.

Figures. Never tried ext3, mainly because it's not a readily available option in Ubuntu. Tried to format to ext3 via the terminal but got a weird error, even after unmounting the drive:
"/dev/sdb is apparently in use by the system; will not make a filesystem here!"
So I booted in to Parted Magic with my netbook, wiped the sdcard, and created a new ext3 partition.
Success!!
The sdcard auto-mounts, and is accessible by Root Explorer, ES File Explorer and File Manager.
Ext3 will suit my purposes just fine. Sorry to make you write all the rest of your post, but it will be a handy reference.
Thank you a million times over!

I'm humbled this post got your attention. Thanks for the great work!

The ext3 format was the default filesystem of Ubuntu, until just recently. It is generally considered better to use ext2 on a SD card. Since a SD card has a limited number of read/writes, a journaling filesystem like ext3/ext4 would use up the limited number of read/writes faster than using ext2. Also, never create a swap partition on a flash drive or SD card.
To format a SD card in Ubuntu, first determine the device name:
Code:

My EEEPC has a 64 GB hard drive, and a 16 GB SDHC card. So the card I want to format is /dev/sdb1. Use fdisk again for the formatting, here are the steps copied directly from my terminal:
Run commands with root privileges (sudo).
Find the disk:
# sudo fdisk -l
Format the disk (sdb1):
# sudo fdisk /dev/sdb1
Command (m for help):d (delete any existing partitions)
Command (m for help):n (create a new partition)
Command action
e extended
p primary partition (1-4)
p
Partition number (1-4):1
Command (m for help):w (to write the changes to the disk)
Format the card. You may need to unmount it first:
# sudo umount /dev/sdb1
# sudo mkfs -t ext3 /dev/sdb1
This is a merged thread, from the two previous posts I created, both questions I awnserd myself. here is the awnser you really want multiple partitions for your phone
First you must run gparted from command promp on your computer, so connect your phone to your computer and run in the terminal:
Code:
adb shell
parted /dev/block/mmcblk0
print
remove any partitions
Code:
rm1
rm2
rm3
rm4
rm5
now create new partitions these partitions should be as so, for sense or 2.1, or gingerbread roms fat32 ext2 swap file is the order, for froyo I believe it is swap ext2 fat32, but I have not tried a froyo rom yet.
Code:
mkpartfs primary fat32 0 14500MB
mkpartfs primary ext2 14500MB 15500MB
mkpartfs primary linux-swap 15500MB 15900MB
now push swap.zip file from below to your phone, and flash swap.zip
now reboot
now open terminal emulator and type:
Code:
ls /dev/block/
this should print something like this:
mmcblk0p1
mmcblk0p2
mmcblk0p3
mntblock1
mntblock2
loop1
loop2
the mmcblk0p'# are the sdcard partitions
to mount the fat32 partition type:
Code:
mount -o rw -t vfat /dev/block/mmcblk0p1 /mnt/sdcard/
now use one of SwapScriptv2.1.1 thanks to cyanogen
type in terminal:
Code:
[B]swapscriptv2[/B]
Follow the prompts and you should see your new swap partition in use, by typing:
Code:
[B]free[/B]
in your terminal now if you woud like to have the swap started at boot time type
Code:
[B]bootswapv2[/B]
rd
and follow the prompts after this you should have a new 3 partitioned sdcard fat32 ext2 and swap and using and mounted on fat32 on sdcard and swap running
using the ext2 will be for either cach2cach appsor maybe linux, I have not decied yet

Flash from Recovery
Compatible with 2 and 3 partition layouts (ext(fat+ext+swap) and no ext(fat+swap))
http://www.mediafire...qdvxh7sos5svcvc
or
http://www.sendspace.com/file/h66oap
This script adds commands to terminal:
Code:
swapscriptv2
bootswapv2
swap-off
bootswap-off
vmtweaks
vmtweaks-boot
swapscriptv2 - you will be asked what partition layout you are using as well as swappiness, optional vm settings prompted
bootswapv2 - you will be asked what partition layout you are using as well as swappiness, and an init script will be placed for swap at boot time, optional boot time vm settings prompted
swap-off turns off active swap partition (error for parition not in use is normal)
bootswap-off removes bootswap init file.
vmtweaks allows changing settings for vfs_cache_pressure and page-cluster, some people have reported success in reducing these values.
vmtweaks-boot allows changing settings for vfs_cache_pressure and page-cluster and applying them at boot.
Let me know if there are any problems with the new script.
the following commands in the terminal
SwapScript: (v1)
Flash from Recovery
fat32+ext+swap or swap on /dev/block/mmcblk0p3
http://www.mediafire...bnc79k6pkespzbj
fat32+swap no ext or swap on /dev/block/mmcblk0p2
http://www.mediafire...b3ykdk3r21js96q
This script adds several commands to terminal:
swapon10
swapon20
swapon30
swapon40
swapon50
swapon60
swapon70
swapon80
swapon90
bootswap10
bootswap20
bootswap30
bootswap40
bootswap50
bootswap60
bootswap70
bootswap80
bootswap90
swap-off
bootswap-off
Instructions
swaponXX (20,30,40,50,60) - will result in swap being turned on with a swappiness of XX
bootswapXX (20,30,40,50,60) - will enable swap at boot time with a swappiness of XX (no usuerinit.sh needed)
swap-off - Turns running swap off.
bootswap-off - removes init swap script from boot. (see above notes for removal if you used the newer script)
SWAPFILE CREATOR:
http://www.mediafire...yr7w2yd5sfobyte
For anyone interested in testing different swap sizes and swappiness or those with no partition other than the standard fat, I threw together a swapfile script allowing for several common configurations. Similar to my swapscript after flashing from recovery a number of new commands will become available in terminal:
Instructions
First create a swap file on your sdcard or sd-ext partition:
swapfileXX (size 12,24,36,64,96,128 on sdcard fat partition)
extswapXX (size 12,24,36,64,96,128 on sdcard ext partition)
Then set swappiness:
swpXX (XX is swappiness in increments of 10 up to 90)
errors in script are normal, script references both fat and ext locations, will fix this next update
swapfile-off (stop swap file in use)
errors in script are normal, script references both fat and ext locations, will fix this next update
clearswapfile (stops swap file and removes all swap files created)
errors in script are normal, script references both fat and ext locations, will fix this next update
Swapfile at boot ONLY SUPPORTED FOR SWAPFILE ON EXT:
bootswapfileXX (XX is swappiness in increments of 10 up to 90)
bootswapfil-off - removes bootswap
SwapFileScript:
http://www.mediafire...yr7w2yd5sfobyte
How to tell if swap is currently in use:
in terminal emulator or adb shell type 'free' with no 's and press enter
if there is a number in the space that says swap you have swap enabled
Hi, here is a good mod specially for gaming and ICS roms which consumes big memory amount!!!
It is basically an .sh script that enables swapping. This makes device use part of sdcard to use it as RAM memory, so it can be increased a lot...
The only requirement is have root, use relatively fast sdcard and have enabled init.d scripts..
WI always have used this mod on my phone so i think it no needs testing
To it follow these steps:
1.- Root your device
2.- Make a swap partition in your sdcard (this step will format your sdcard!)
http://forum.xda-developers.com/wiki/SD_card_partitioning
2.1-In step 3 select "swap partition"
2.2-I recommend to make ~512MB partition because the SO will be going to fill it during you use the phone, but i always had 1GB partition, and no problems You can select 100MB or 50MB, but this is too little
3.- Check if there is a folder called init.d inside /system/etc/
3.1-If its there, follow next steps
3.2-If it is not there, you must activate init.d support, follow this tutorial: http://forum.xda-developers.com/showthread.php?t=1422061
3.- Copy 00userinit file to your device (must remove the .txt extension of the file, because i needed to put it to attatch the file)
4.- With root explorer, xplore, or similar copy it to /system/etc/init.d
5.- Set all permissions: rwxr-xr-x
6.- Reboot device
7.- For checking if it works, download Terminal emulator and type "free". See attatchment.
8.- If "swap" line has no "0" value, it works, congratulations

With this, you will:
Have swapping activated in your phone permanently, or until you remove that script or change of ROM.
Have bigger RAM memory amount, depending on your swap partition size
If you use supercharger or any RAM manager program, i should recomend you to activate hard gaming option, because:
-As you have bigger RAM memory, the useless aplications, instead of be closed, they will be stored in your sdcard partition so, you re able to have multitasking and hard gaming option at the same time

But this is not all!! You can open and edit this file to adapt it to your requirements:
You can edit this line to set swapiness cuantity, this defines the OS tendency to use swap partition, I not recommend to set it to 100, but 60 is good. Also, if you have slower sdcard, you should set it to 30~40:
-Change 60 value by something you want from 1 to 100 "then echo 60 > /proc/sys/vm/swappiness;"
If you have another sdcard partition like EXT4 or something to APP2SD, you should change the last number of "mmcblk0p2" by the number of the partition, i mean:
-If you have 3 partitions with this order: Fat32(that you use everyday), EXT4, and SWAP you should change it by mmcblk0p3
-If 3 partitions with this order: Fat32, SWAP,and EXT4, you should set it mmcblk0p2

Does it works on locked bootloaders, obviously on gingerbread??????
i already have linux swap partition and use "swapper 2 " with doom kernel
after using swap we should disable ( turn off ) the swapper2 and then mount the SD card to computer ... so , my question is , is your script the same ? or it can disable - enable itself automatically ?

That is what says some people, but i always have used it and no problems...
In addition, sdcard life is sure longer than 10 years, if you use swap constantly it could be reduced to7 or 8...
Then, it makes no sense to say that, because you probably will buy another sdcard in less than 5 years
I tried this without success. I had to change the script that you provided. First I added #!/system/bin/sh to line 1 so it would run as a shell script and then the partition on my device was /dev/block/mmcblk0p3.

Once I edited the script with the addition to line 1 and the correct partition everything worked as expected.

i think its different, i dont know how does it work, but reading its description I think that this app creates a swap file, instead of using swap partition.. I think this is worse method than i have posted, because system compresses all swapped memory into a file,so it could be slower... In addition, you must install an app to make it work, which means a service running in background, less space for other apps, etc,etc...
I dont know, but i think my method is better

Yes. I never partition from my phone. Insert ur card into ur laptop and partition with paragon partition manager (or your choice). If you have some free space on it you could easily resize ur fat32 partition to make it smaller and then use the unpartitioned space to make a linux swap partition or en ext2/3 for link2sd, if u want (I have both).. Did it lots of times. No problem

you said replace mmcblk1p2. what does that mean? how to?
check cat /proc/partitions from terminal which is the 2nd partition of your MicroSD card. if you did not create 2nd partition yet, will tell you.

ext4? im not sure if you meant that
get a terminal emulator app (or connect phone to PC adb shell) and check the output of following command:
Code:
cat /proc/partitions

if your 2nd partition is mmcblk1p2 then just mount /dev/block/mmcblk1p2 as in post #6 (nothing to replace)

How can I check that? I dont understand the output of the command
you can double check first partition with grep /dev/block/vold /proc/mounts
Code:
:/ $ grep /dev/block/vold /proc/mounts
/dev/block/vold/public:179,129 /mnt/media_rw/8075-15FD vfat rw,dirsync,nosuid,nodev,noexec,noatime,uid=1023,gid=1023,fmask=0007,dmask=0007,allow_utime=0020,codepage=437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0
in my case 1st partition is
179 129 1935608 mmcblk1p1
therefore next minor is 2nd partition
179 130 1935607 mmcblk1p2
