[Q] Move /cache to /sd-ext/cache

On Desire I have rooted stock Gingerbread with a2sd. Only app data are on /data partition, but it's still not enough. So I want to move /cache to /sd-ext/cache and /system/app to /sd-ext/app-s. Then I want to flash CM7r2 hboot.
So my question is how can I do this (moving to sd-ext)?
Thank you

To clarify, you mean Dalvik-cache, not /cache?!

no I mean /cache (the one which is on 40MB partition). Dalvik-cache I have currently moved to sd (was by default on pre-rooted stock).
I want to flash hboot with only 5MB /cache and it will not be enough for downloading some apps from market, I think...

Right I see.
You can either use the 06mountdl script found in many AOSP roms to bind /cache/download to /data/local/download (but that then means you have to save a portion of /data for download space) or better yet:
Fixing market downloads
If you wish to bypass the problem of the small cache partition limiting market downloads, then do the following steps:
1. Use the wonderful dsixda kitchen to unpack your boot.img
2. Edit the init.rc. In the exports section add the following:
Code:
export DOWNLOAD_CACHE /mnt/asec/download
and add the following right under the section titled "# Secure container public mount points":
Code:
# Market downloads
mkdir /mnt/asec/download 0777 root system
mount tmpfs tmpfs /mnt/asec/download mode=0777,gid=1000
This will place all market downloads into a temporary ram disk, which will be deleted upon the completion of the installation.
3. Repack your boot.img and place it in the rom.
You can see an example of an edited init.rc here:

and following editing 06mountdl and putting in init.d could work also?
Code:
mount -o bind /sd-ext/cache/download /cache/download

You can try but you are already mounting sd-ext for apps2sd so it will likely make a mess of things. Adding to ram disk is by far the neatest solution.

thank you rootSU very much

No probs. Let me know how you get on.

I just run a small script which binds cache to /data/market temporarily for that boot.. Same thing, but cleaner than either init.rc or init.d, and reversible instantly.

This is actually good if you're running data2sd. or mount it to whatever is the mount point of sd-ext/elsewhere
Click to expand...

The problem with bind if you're not using data2sd is that you are not only -15MB for usage but also -download+install. So you have 200MB /data but can only use .170. Waste. Anyone not using data2sd, RAM disk is by far the best

I agree it doesn't make sense if your /data is an mtd. but I thought OP wants to use sd-ext. he can bind a sub folder of whatever mount is used for sd-ext. in that case, cache inherits the free disk space of sd-ext

Droidzone, can you please post here your script and how to use it?
thank you

Here you go
https://www.box.net/shared/zt6si0qjaz6c63z8hhz2
To run it,
From a terminal:
su
bash /sdcard/cachebooster.sh
Or run it as root in Script Manager app. (easier). Dont forget to add correct location.
If you want to make it run every time phone boots, copy it to /system/etc/init.d

So I used this part of your cachebooster.sh and I have placed it into init.d:
http://pastebin.com/tiGX7A1E
after boot, cache is on sd-ext, but market gives error 492 at download of any app.
Secondly I tried to symlink all system apps from /sd-ext/app-s to /system/app with following script:
(before executing I copied all apps to /sd-ext/app-s)
Code:
#!/system/bin/bash
rm /system/app/*.*
cd /sd-ext/app-s
filelist=`find . -type f`
for i in $filelist
do
if [ ! -e /system/app/$i ];
then
chmod 644 /sd-ext/app-s/$i
ln -s /system/sd/app-s/$i /system/app/$i
fi
done
exit 0
But it gave me a bootloop....
I think it's too much linux for me
I wanted to use Supernova 2.4 ROM at first, but with my class 6 ADATA I had terrible lags, which lead to unusable system and phone overheating. So I wanted to customize stock pre-rooted Gingerbread for CM7r2 hboot.

Hmm.. Sorry I don't know why you're getting that error. It's working fine for me. It's the only way I can download apps more than 50 MB in size. Before adding it at boot, just run it from a terminal and see what happens. Maybe it interferes with some other script on your ROM.

thanks anyway Droidzone!

Like I said, it doesnt like mounting sd-ext for cache AND apps2sd. It gets messy and doesnt work properly. I tried to get it to work properly for weeks. Init.rc or 06mountdl.

Hmm ..
Can someone get me the output of this command under a2sd+?

[GUIDE] Mass Storage

If you aren't satisfied with transferring files over MTP for whatever reason, I have done some digging and managed to get mass storage working for the external sdcard.
I developed some scripts for switching to and from mass storage, using posts for the GT-I9300 and for the Xperia S. You can unzip them (attached) to the root of your internal sdcard. You can then easily import them into GScript Lite, available for free through the Play store.
For reference, the commands are as follows:
Mass Storage:
Just plug in your phone and run:
Code:
echo 0 > /sys/devices/virtual/android_usb/android0/enable
umount /mnt/extSdCard/
echo "mass_storage,adb" > /sys/class/android_usb/android0/functions
echo "/dev/block/vold/179:97" > /sys/devices/virtual/android_usb/android0/f_mass_storage/lun_ex/file
echo 1 > /sys/devices/virtual/android_usb/android0/enable
If Windows fails to find the correct driver, go to the Device Manager and manually set it to use the driver, "USB Mass Storage Device". It seemed to try to stick with the MTP driver in my case.
MTP:
Unmount/Eject in your operating system first, to be sure. Then:
Code:
echo "" > /sys/devices/virtual/android_usb/android0/f_mass_storage/lun_ex/file
echo 0 > /sys/devices/virtual/android_usb/android0/enable
echo "mtp,acm,adb" > /sys/class/android_usb/android0/functions
echo 1 > /sys/devices/virtual/android_usb/android0/enable
vold
Notes:
/sys/devices/virtual/android_usb/android0/f_mass_storage/lun/file seems to be prepared for the internal sdcard, but I have had no success in using it in conjunction with the device, /dev/block/vold/179:96. At least the external works.

and it stays without having to continually type all that?

If you stop after the first script, unfortunately it's not going to remount the external sdcard. This does not enable a convenient UI toggle like you might have seen on other ROMs.
I recommend saving the first sequence of commands as "Mass Storage.sh" and the second sequence as "MTP.sh". You can copy them to /sdcard/gscript/ and load them into GScript Lite as new scripts. Then it's easy to activate mass storage and deactivate it at the push of a few buttons. (GScript Lite seems to crash on me after running the scripts, on exit, but to no ill effect.)

Any way to get this into an app?

Someone could develop a specialized app, but I recommend trying GScript Lite in conjunction with the attached scripts.

thanks for the tutorial.

Woohoo!! Thanks so much for figuring this out.
[I'm having to explicitly remount the external card in the MTP script:
mount -t exfat /dev/block/vold/179:97 /mnt/extSdCard
and mount doesn't seem to be happy without an explicit type - any way around that?]

That's interesting. I didn't encounter that issue. The only difference I'm aware of is that I reformatted my card using mkfs.vfat, but you could try appending the following to the MTP script, and see if it works equally well:
Code:
vold
The whole script would become:
Code:
echo "" > /sys/devices/virtual/android_usb/android0/f_mass_storage/lun_ex/file
echo 0 > /sys/devices/virtual/android_usb/android0/enable
echo "mtp,acm,adb" > /sys/class/android_usb/android0/functions
echo 1 > /sys/devices/virtual/android_usb/android0/enable
vold
If that doesn't work, your solution might be the best one for now. Let me know if this works. I don't see any harm in adding the line, in any case.

Yes, that works - thanks again!

Just.. Perfect!!

Well, works well at home on w7 but the Xp at work doesn't want to play.

If you can install drivers at work, check the directory thread. Or, just download the Samsung SGH-I747 USB Drivers. If you can't install drivers at work, then you may be out of luck.

It would be really great to make this into an app with a widget. Really great.

Is there any reason that this would not work on a T-999?

I actually got it going by uninstalling the drivers, deleting Samsung folder, reboot PC . Plugged in phone, it installed drivers from there. Funny thing, after drivers installed, prompt popped up, selected view folder and wala. Weird I didn't have to run script again before the prompt.

Not to say a dedicated app wouldn't be an improvement, but GScript Lite provides the ability create widgets to run different scripts. You could have one to switch to Mass Storage and another to switch back to MTP. I actually had that setup for a while, but decided I'd rather have to go through an extra couple of steps than risk running the scripts by accident.

I have made an app for the purpose. It is still in alpha stages

USB mass storage drive trick
BooM there it is! sweet, and thank you very much.
If Windows fails to find the correct driver, go to the Device Manager and manually set it to use the driver, "USB Mass Storage Device". It seemed to try to stick with the MTP driver in my case.

I succesfully used this script here to swap internal and external sd cards. Now I want to mount the formerly internal sd card. This should be possible as it is now booting from the external card.
I tried the following but it is not working. Any ideas? umount /mnt/extSdCard/
echo "mass_storage,adb" > /sys/class/android_usb/android0/functions
echo "/dev/fuse" > /sys/devices/virtual/android_usb/android0/f_mass_storage/lun/file
echo 1 > /sys/devices/virtual/android_usb/android0/enable
here are my df results - you can see that the sd cards are switched:

There is an app originally developped for i9300 but it definitely works on I747(M)
:good:This solution works elegantly - read my comments regarding the very few existing hiccups.

CWM can't mount SD

I just rooted my phone and installed CWM. When I try to install a zip from SD it says "E: can't mount SD" i've tried everything (manually mount SD card and format external card from CWM and phone and nothing happened!) does anybody now a solution? can I installa a ROM from internal memory? i guess i can't...
thanks a lot!

Thanks. I have updated it but the problem persists

Have you tried twrp recovery? If nothing else use internal storage.

Your SD card is most likely formatted in exFAT filesystem. This is a MS proprietary format that requires licensed drivers to mount. As of now there are no custom recoveries that can mount exFAT.
There are a few options:
1) Re-format the card to FAT32 and do backup.
2) Get a smaller (8-16gb) card to use for backups and keep in FAT32 format.
3*) Partition larger card (32-64gb) with multiple partition types. ex. 40gb exFAT/24gb FAT32. *Please note that I have not tried this nor seen it done but just an idea I wanted to try out to see if it was feasible. I may have time to give it a shot later today and if so I'll update this post.

Do not partition a 64 GB micro SD to FAT32. Performance will be awful because of the way the mem blocks are sized.
Also, your internal SD is exFAT... that is read by the recovery perfectly fine.
I would say save yourself some trouble and just find a ROM kernel combo that supports exFAT micro SD. Your 64 GB will work flawlessly and performance will not take a hit.

maybe post in correct forum for more replys, just sayin

I currently understand the recovery image to work as below. Someone please correct me if it's incorrect.
While the kernel does support exfat the "interpreter" (driver) and custom recovery image can not talk to each other. The exfat driver can only be called/read if you know which system calls to use and how to interpret its response. The custom recovery image does not know how to utilize the exfat driver.

Doesn't work on XMD
Any idea?

It's so interesting but in my Xperia M, SD-Card is in /dev/block/vold/179:32, no /dev/block/vold/179:33 as in this (and other) instructions.
When i set to program 179:32 all works good.
Thanks

Xperia M Single but you should go to /dev/block/vold/ (Root Explorer) and check where has been adressed your SD-CARD
P.S This metod is not great beacause this program not swap, only set sd-card as intrenal memory. Propetly internal memmory is dissapear so better is using other method.

I see no reason why that would't work.
Have you checked where is adressed your SD card?

I'd tried with other options too, with this, unfortunately not working, and reason is unknown.

SM-T310 Swap ExternalSD to Internal

Original thread can be found here.
Credit to :
xalien8dx
mattiadj
I have modified this script to work with the SM-T310. If you want it to work on other Tab 3 models you will need to provide me your external sd card device node.
Follow instructions in the quoted text below using the script attached to this post.
Here's a script I modified originally its a script written by mattiadj so I gotta give him props
Here's his thread its for the Galaxy S III I think - http://forum.xda-developers.com/show....php?t=1772234
This will make your external SDcard as Internal and your Internal SDCard external
It mounts data/media to your extSdcard
Please make a backup before you do this, just in case.
Let me know if you have any problems
1. Anyway.. you will need to place this script in your /data folder (Yes you need to be rooted)
2. Next use ES file manager and give it 777 permission (For the non-linux users, that's full permission on it, Read, write, execute for just user)
-----------------to do this with ES file manager just press and hold down on the file and look at its properties. At the bottom you can see Permissions, hit the Change button and check-mark everything for user
3. Use Smamager (Download it if you dont have it, ... .its free) and goto the script file and open as script/execute, then when it opens choose "Is executable" and then click "Su" & "Boot". Click "Save".
4. Reboot and enjoy.
To go back to the normal setup just delete the script or open it back up in smanager and clear the SU & Boot options.
In order for some apps to function properly you will have to copy some folders from your old internal sdcard to your "New" one.
For example.. aptoide wouldnt work until the aptoide repos folder was copied over. If you want you can just copy over everything to be safe. I on the other hand just picked and chose what I needed

Untested so your device might be consumed by the Banefire, but find attached the script requested with the appropriate change.

my english is very bad.i can't understand forum topics.
my SM T210 7.0 how swap memory?
sorry for english

Exfat and vfat are the same for system type no need to reformat your card.
This script is known to work on the 310 (8" WiFi only). At this point the 210 version (7") apparently does not work. The banefire burns strongly.
The script allows the external SD card to be used in place of the internal SD.
sent from a buggy xda app by some miracle

Does this work for T210?
Please make an test version for it atleast.

any way to get this to work on t211 ?
