100% used space on /system and cannot mount as r/w, why? - Galaxy Note GT-N7000 Q&A, Help & Troubleshooting

Hi Guys,,
I have installed CF3D on my GNote but when I was about to install CF Drivers it says that my /system is insufficient, so I check it right away by using df -k on a terminal emulator and found out that 100% space used on /dev/block/mmcblk0p9. My solution to this is to remove some system app, I have tried Titanium backup but no good,so i decided to use root explorer and delete some app is system/app, the weird thing is that i could not mount the /system as r/w, so i decided to remount /system as rw using a terminal emulator, i used this command
mount -o rw,remount /dev/block/mmcblk0p9 /system
but still i could not delete data on /system/app... another weird thing is that I could not list the directories or files in the /system using "ls" command in terminal emulator, the error says, "value too large for defined data type".
My questions
1. is this part of the mmc_cap_erase bug, because if i remember very well, i have flashed something on cwm which causes FC's on my device right after that, my internal sd card and external sd card is unreadable , and then when it ask to reformat it and i click yes, then everything is ok, after that i changed ROM (from criskelo v8 to kingdroid v3) and i never encountered that bug again.
2. is there any way to mount /system as r/w? or is there any other way to uninstall system app. Ive tried every "free apps" on the market to uninstall system app but i could not find a successful one.
3. if this is part of the mmc_cap_erase bug, can i used the fix in this thread http://forum.xda-developers.com/showthread.php?t=1667886 to solve my problem??
Thanks to those who are willing to give me some advice.

/mnt/sdcard AND sdcard problem--> Need Help

Sorry if this is in the wrong thread-mod can move.
Yesterday I was trying to install Mobile Defense as a system app as reccommended by MD website and instructions using adb push. Somehow it didn't work real well and I ended up with TWO sdcard directories.
In Root Explorer, one is /mnt and one is /sdcard (like always). The/mnt also has /mnt/sdcard, /mnt/asec and /mnt/secure. The /mnt/sdcard has duplicate entries of /sdcard and is screwing up loading/flashing kernels, etc. I have tried to delete this /mnt directory after Mount R/W in Root Explorer, but it keeps coming back!
I'm not very good at the whole coding/language thing and could use some instructions (4 noobies) as to how to get rid of this file without a total wipe. THANKS in advance
Wrong section.
I believe /sdcard is a link (shortcut) to /mnt/sdcard.
So, depending on your ADB commands, anything that says /sdcard, try changing that to /mnt/sdcard and see if that works better.

Ok, thanks. The problem is that I downloaded IR's lastes 0524 925 BFS kernel and it shows in recovery as on the sdcard, but when I tried to flash it, the flash failed and said it couldn't find the file on the sdcard. I assumed it was looking in two places at once and got confused/conflicted, therefore it quit?

[Q]It shows there is no free space in system/lib in JP6!

Hi!
I flashed JP6 yesterday, and I want to do internet browser fix and One Click Lag Fix.
But when I copied libwebcore.so to /system/lib or Install EXT2 Tools, It always no free space /system/lib
Now I can only use update.zip to put the files into /system/lib, but OCLF still can not work.
Any help?
thanks!!

I notice 2 things with JP6 (installed from Kies via registry mod). Not sure if everyone else is the same.
1. cp command is missing, but mv & rm are present
2. /system is mounted read only
So to make sure the internet browser fix works fine, you'll need to make sure your a.) phone is rooted, b) remount the /system as read write, c.) and then install busybox to use the cp command (if you're installing libwebcore.so by command line, otherwise you can use the file manager to copy files).
There is only about 10MB free space on /system with JP6 (with 803 pit, I believe).
Check this with:
df -h
Also, /system is mounted read-only so you have to remount it as rw before making any changes.
mount -o remount,rw /system
+1 and whenever I try to move an app to sd from the menu in settings>applications>manage applications>app name>Move to SD
It throws an error "Failed to move application. Not enough memory."
I wiped my entire phone clean and still it throws the same error. My internal memory (16 gb) has 10 gb free. The app that I'm trying with is Instant Buttons.
The dev has included move to sd option. Yet it does not work.
ive only got 300kb free in my /system partition on JP6. considering moving modules off to /data and adding it to the path to free up some space. its unworkable like this.

[MOD]SD Swap v5+Initd for any 4.1.2 rom Locked or unlocked xt907+CM4.3alpha-version

Update something
[Edit Philz 6.2.3+ is perfect & does not mess with my swap anymore.]
messed with the install-recovery.sh!
So just reflash the swap , not sure what did it : an xposed modual?
v5 up.
Works now even if on bone stock.
Step 1: (for those rooted, on the ota or out of the box)
Install this https://play.google.com/store/apps/details?id=stericson.busybox
Use the smart install & choose 1.21.1 not 1.22. http://forum.xda-developers.com/showpost.php?p=50064227&postcount=4
Do not use Universal init d.
Reboot.
Step 2:
Flash v5 with Twrp2.6.3 e33 or Philz v6079.
For SafeStrap users using bootstrap, should work.
Reboot.
TWRP e33: http://forum.xda-developers.com/showpost.php?p=49509466&postcount=1
Fixed conflicts with my ◢ PurePerformances™X ◣ mod.
You can only successfully install with Plilz v6079. I only use, for now the one below.
Once installed TWRP does not seem to be a problem.
Plilz v6 for msm8960 phones: Atrix HD, Razr M & Photon Q is here
Took down the deodexed version as it was only the ui from this 1% battery mod that made it different. You can flash it to any deodexed 412 xt907 or xt905 rom.
All storage defaults to storage0 (your real SD card) which is the way it should have been from Motorola, well closer anyway.
Flash from recovery or SS bootstrap Philz v6. Wipe dalvik & cache only. Not for cm based, multuser, or anything but 4.1.2 stock roms!
My ◢ PurePerformances™X ◣ mod must be followed by the SD Swap. Because of a conflict with install-recovery.sh file.
Do not use cwmr 6044 as it messes up the swap by forcing data/media/0. Plilz is better as you can choose data/media only. See my goodies for Philz.
Always use TWRP 2.6.3 e33 OR Philz v6079.(for install use Philz only)
Always choose any NO when rebooting from Philz.
Go Recovery Goodies
Because install-recovery.sh is now an agent in the initd setup & needs to be protected.
Notes on the SD swap: When you choose "Device storage", sdcard0 or storage0 you will browsing your real SD card. When you choose "SD card", sdcard1 or storage1 you will be browsing the internal SD ("data/media").
This internal SD ("data/media") memory now has no purpose. You can move what you want to your real SD & delete everything else to let the phone use it all. All storage defaults to storage0 (your real SD card) which now is the way it should have been from Motorola, well closer anyway.
ZaYAC-ua's swap thread
The formerly unwanted file: install-recovery.sh is now an agent in the initd setup & needs to be protected, as noted above, and it's permissions, if altered, can be restored to rwxr-xr-x.
If this file is not protected you boot up with 2 internal SD cards.
Known issues:
Two things will Kill the SD swap: (by messing with install-recovery.sh)
1)Using TWRP older then v2.6. (To install use Philz only)
2)If you boot from CWMR and choose yes to "disable recovery flash".
Also) If you mess with multiuser roms feel free to delete 0 , obb & legacy folders in internal sd (storage1).
One more) It is expected for your settings-storage info to be out of whack.
Finally) Create folder in root of the phone with Root Explorer results in an error but is the same as the Rabbit's version & of no consequence. The folder does get created anyway. All else works in the root of the phone.
UsbMassStorage: BE SURE TO EJECT FROM PC/MAC BEFORE YOU UNMOUNT. DO NOT USE WITH ANDROID FILE TRANSFER.
".files" are a nuisance when mounting to osx: just delete them AFTER YOU UNMOUNT. Warning: If you do not enable your file browser to show hidden files & you unmount while your (os x is one) trash is full the .file can be huge!

V3 up. Fixes compatibility w/ PP mod. Twrp will not install the swap & let it work! Plilz v6 will & does twrp restores too....
I'm using this script to swap the storage on PACman and other 4.3 roms that lacks the swap option natively, I guess your solution is more or less the same, using the restore recovery script instead of the real init.d script.
Right ?
Code:
#!/system/bin/sh
sleep 3
mount -o remount,rw /
mount -t vfat -o umask=0000 /dev/block/vold/179:97 /mnt/shell/emulated
mount -o bind /data/media/0 /storage/sdcard1
chown system /data/media/0
chgrp sdcard_rw /data/media/0
chmod 0075 /data/media/0
mount -o remount, ro /

Thanks. Did you have a link? I have never found one that works for 4.1.2 + !

A link ?
That's all I'm using, just copy it save it to (say) 02sdswap, put the file in the /etc/init.d folder and set the permissions as the other init.d files.
Then reboot the phone.
That's all
Keep in mind to use a decent editor and set the end line format to UNIX.
I'm using it on 4.3 on PhotonQ but it should work, as is, on other similar phones like the Razr M, or with little adjustment in other phones.
Is far from perfect but looks to be enough to solve the problem.

Just tried it, removing the "/0" from each line w/ datamedia.
No go for 412.

Practically I've never used JB 4.1.2, as I see no point in doing it.
Depending on my moot I use my internationalized ICS, or a good 4.3 unofficial rom.
Bacause this, I don't remember exactly the changes in paths and symlinks between 4.1.2 and 4.3
But very likely the /mnt/shell/emulated is not present on 4.1.2, just check if I'm not wrong, and eventually change the /mnt/shell/emulated to the correct mountpoint.
V4 up. Much improved. Only the install-recovery.sh annoyance to overcome. I am trying a "userint.sh" version. Anyone know if that is do-able on a moto phone? Htc phones use it with a swap.
Couple this concise commentary of the data media problem,
http://teamw.in/DataMedia
[translation: data/media is useless if you have ext sd as default storage.
It needs to be formatted for reliable rom flashes (esp. 4.4)
& you can do it from Philz! ]
With the ability to use a large sd card on our phone,
then you understand why keeping data media zeroed out along with a sd swap is so nice.
Where oh where is a swap for 4.4?
Btw a new Plilz with ext sd cwm folder detection :fingers-crossed: due out soon.

cannot mount ext partitons (or anything) under lollipop

Yes i can't mount any partiotion of the sd card to the phone under lollipop, i tried everything, this is because i can't use link2sd or foldermount, so i tried using commands in terminal emulator like mount -t sdext4 -o rw /dev/block/vold/179:66 /data/sdext2 , the command seems to works at first but the folder is still empty, i used the directory bind commands lime mount -o bind but this isn't working either, it seem that lollipop broke something in this phone or is using another metod.
Foldermount isn't working for me either. Be aware of namespace isolation for mount as default in SuperSU. Check it here http://su.chainfire.eu/#how-mount
Same Here. I have Stock 5.0.2, root, TWRP. I can create a Mountscript with Link2SD, but after the neccessary reboot, it is impossible to move items since "/data/sdext2 could not be mounted". I think, some boot procedure from Motorola messes with the Link2SD Skript.
Okay little UPDATE: If you go into supersu and disable this namespace option, sdext2 can be mounted. Link2SD warns, that the mounting isn't possible while booting , so the apps moved by Link2SD are invisible. If you do a quick reboot from Link2SD, the apps can be seen. So it works, but is rather complicated. Also, not every app seems to be movable...

[GUIDE][ROOT] Link2SD

Link2SD GUIDE
ROOTED DEVICES ONLY
Link2SD is a good solution to save the contents of your internal memory, I know we have a lot but its a good idea in the case of saving more space on your internal memory.
Back up your external sd contents before proceeding!
STEP 1
Install these:
https://play.google.com/store/apps/details?id=stericson.busybox
https://play.google.com/store/apps/details?id=com.sylkat.AParted
https://play.google.com/store/apps/details?id=com.broodplank.initdtoggler
https://play.google.com/store/apps/details?id=jackpal.androidterm
STEP 2
If you've already installed busybox, skip this step.
Install busybox using the busybox installer into /system/xbin
STEP 3
After install, unmount your external sd card from System/Storage/Unmount SD Card
THEN, unmount your external sdcard and sdext2 partition if you have one, from terminal emulator.
Thsi varies from ROM to ROM, I'm on CM11, so I run these commands
Code:
mount -o remount,ro /storage/sdcard1
umount /storage/sdcard1
mount -o remount,ro /data/sdext2
umount /data/sdext2
If you're stock, do this...
Code:
mount -o remount,ro /storage/external_SD
umount /storage/external_SD
mount -o remount,ro /data/sdext2
umount /data/sdext2
Again, rom specific. If you don't have an sdext2 partition, no need for the BOTTOM TWO commands.
STEP 4
Open AParted and resize your external sd card's partition, then make yourself an ext4 formatted sdext partition. Mine is 8 GB in size, since I have a 16 GB card. The journal write takes a long time...usually about a minute and a half. Don't cancel it or you'll end up with a corrupt sd card.
STEP 5
Remount your sd card by your system menu, this is the easy way.
STEP 6
Toogle init.d in Init.d Toggler. Only for stock ROMs without init.d support. Skip this if you've already done init.d or have a ROM that has it baked/enabled.
STEP 7
Install Link2SD and the pro key. The pro key costs money, so if you're poor than I'm sorry. I'm really poor, it's only a few bucks. XD
https://play.google.com/store/apps/details?id=com.buak.Link2SD
https://play.google.com/store/apps/details?id=com.buak.link2sdplus
Run Link2SD after both are installed. If done correctly you'll get a prompt asking you to create your mount scripts, so select ext4 format and confirm, then CANCEL reboot. Go to Link2SD settings and enable Relink Lib files and Relink .dex files at boot. I also make my cache auto-clear every 6 hours or so. Auto link is a really bad idea. Since some system apps break when you link them. Clear the app and dalvik cache. Some of your apps may crash. Recreate your mount scripts again, then REBOOT.
STEP 8
Go into Link2SD and link all your user apps, you can use the filter at the top and serlect "User" to see which ones you installed. DO NOT link anything that modifies your system, since those apps are known to break. For example, voltage control or ROM Manager / ROM Toolbox break when you link them. Since you have the pro version you can link the internal data too!
DO NOT link any system apps. This is a likely known cause for a brick.
DO NOT link CM themes.
DO NOT link launchers.
STEP 9
You have successfully installed Link2SD and have it working! I suggest installing SD booster or making yourself an init.d script to boost your read ahead speed at boot. This helps A LOT with app execution on older sd cards.
I hope this guide helped! Remember, if you fark up you did it to yourself! I'm not responsible.
The L90 D415 is awesome!!!

Partitions with cwm can work too?
I don't use cwm, but TWRP, so wouldn't know.
