hi,
how do i mount/unmount sdcard with terminal?
To unmount ,i tried using
umount /mnt/sdcard
but i got device busy
umount /mnt/sdcard/.android_secure then
umount /mnt/sdcard
i have unstable results.
for mount,i tried to used
mount -t vfat /dev/block/vold/179:65 /mnt/sdcard
seems everythings ok.
i also saw this vold command.tried it but dont really know it works.
can use this to mount/umount the sdcard?
thanks

did you get an answer?? Can you share ??
----------------------- Journaling Disabler For Pico ----------------------
This is just a simple Zip to Disable Journaling on pico! as we use 2 or 3 extra ext4 partitions for OC!
It even clear's /sd-data,/sd-cache - for aosp
and /sd-ext,/sd-data,/sd-cache - for sense 4
Which means you need not always format your sd-card to switch between roms! .. But if you are switching from aosp rom to sense 4 you need to partition the sd-card appropriately!
Steps to USE:
******* Use this Zip Only when installing a Rom from scratch!... cause it wipes everything! ******
-- clear almost everything you can from recovery e.g factory-reset,/system,/boot,/cache etc
-- install this Zip! as like you do with any other zip (Prefered Recovery TWRP 2.4.X)
-- Flash Your Favourite Rom Now!!
I can use this even if i am not oc'ing?? Just like superwipe?
Disabling journal wont harm anything! Right?

From the wikipedia's article:
A journaling file system is a file system that keeps track of the changes that will be made in a journal (usually a circular log in a dedicated area of the file system) before committing them to the main file system. In the event of a system crash or power failure, such file systems are quicker to bring back online and less likely to become corrupted.[1]

For overclocking, the SD Card is used for the /data and /cache partition. In that case, the SD Card would be read more frequently as the /data and /cache partitions are the most frequently accessed and modified partitions while running the Android system. In that case, using a Journal would slow down the memory access times if the SD Card is not fast enough. Also, as many modifications are made to the /data and /cache partition, the SD Card would be going through the read/write cycle twice the number of times, once for the journaling and once for the "commiting them to the main file system". So, it is likely that the SD Card might get corrupted faster than it normally should. That is the reason why Class 4 and below SD Cards are likely to "go dead" soon when overclocking with cute_prince's new PLL2 overclocking method. And, this is why ateeq72 has made this flashable zip to disable journaling. It would reduce the possibility/risk of losing your SD Card and at the same time allow you to OC your phone.
Using this when you are not OC'ing your phone? I wouldn't recommend that you flash this zip, but you would need a slightly modified zip. Also, journaling, I presume you want to disable in your phone's sd-ext memory. It would increase your phone's performance in case you are using any memory increasing scripts like int2ext which mount the sd-ext partition in the /data folder.

Thanks man!
Can you tell what is to be modified in the zip so that i can use it when i am not oc'ing?

Edit the file named "ateeqscript" using Notepad++.
Make sure the file looks like the one below.
Code:
#!/bin/sh
echo ***************Begin Disable Journaling Partition***************
/sbin/busybox mount -t auto /dev/block/mmcblk0p2 /sd-ext
rm -rf /sd-ext/*
/sbin/busybox umount -l /sd-ext
/tmp/tune2fs -O ^has_journal -c 1 -i 1d -m 0 /dev/block/mmcblk0p2
fsck.ext4 -Dfy /dev/block/mmcblk0p2
sync
echo ***************Data Partion Done***************
echo ***************Finished No Journaling Partions***************
What I have done? Simple. Removed all code related to /sd-data and sd-cache, and kept only commands necessary for the sd-ext partition.
---------------------------------------------------
@OP, I suggest a few changes in your script. First, the mounting commands are run, so, if the sd-ext is already mounted by the recovery (just in case, accidentally it happened), then, you wouldn't (or rather shouldn't) be able to mount it in another folder, namely /sd-data. I would suggest the following change in your flashable zip. Try to make it look something like the one below.
Code:
#!/bin/sh
echo "\"Disabling Journaling\" Script"
echo "Initializing script..."
/sbin/busybox umount -l /sd-ext
/sbin/busybox mkdir /sd-data
/sbin/busybox mount /dev/block/mmcblk0p2 /sd-data
/sbin/busybox mkdir /sd-cache
/sbin/busybox mount /dev/block/mmcblk0p3 /sd-cache
/sbin/busybox mkdir /sd-ext2
/sbin/busybox mount /dev/block/mmcblk0p4 /sd-ext
rm -rf /sd-cache/*
rm -rf /sd-data/*
rm -rf /sd-ext/*
/sbin/busybox umount -l /sd-data
/sbin/busybox umount -l /sd-cache
/sbin/busybox umount -l /sd-ext
echo "Disabling Journal in sd-data"
/tmp/tune2fs -O ^has_journal -c 1 -i 1d -m 0 /dev/block/mmcblk0p2
fsck.ext4 -Dfy /dev/block/mmcblk0p2
echo "Disabling Journal in sd-cache"
/tmp/tune2fs -O ^has_journal -c 1 -i 1d -m 0 /dev/block/mmcblk0p3
fsck.ext4 -Dfy /dev/block/mmcblk0p3
echo "Disabling Journal in sd-ext"
/tmp/tune2fs -O ^has_journal -c 1 -i 1d -m 0 /dev/block/mmcblk0p4
fsck.ext4 -Dfy /dev/block/mmcblk0p4
sync
echo "Partitions Journaling Disabled..."
echo "Finished no journaling partitions"
Do we need to flash this zip for every new rom or just once is enough?

i guess one time is enough no need to flash again and again
@ateeq72
Can you edit this script with just the wiping part? As it is not necessary to disable journal for aosp roms!

I've read that it formats through ext2/4 ! What i want is the parition to be remain untouched..

journal disabling is required for only ext4 partition for max performace
if u dont use ext4 use any wiping script
the script keval gave format partitions to ext2 only not ext4

NOTE:------------>Do remember the script of sense will format partitions as EXT2 and script for aosp roms will format partitions as EXT4 and sense 4.1 sctript will also format as EXT4

u can check the script it formats as ext2 i had also checked from sd card its ext2
i also had thought that as it was given in thread but its not
is it updated script which u posted in facebook

Bro thats why i have mounted sd-ext as "sd-ext2" ! to make sure every recovery doesnt have any issue mounting it!
what is journal?
in many posts i found this about this journal what is this actually..
hi i got an lg e610v
i've installed a custom firmware : 20d+root+cmw
wiped
installed cyanogenmod 11 and last Gapps
i've partitioned the SD card with partition magic tool
1 : Fat - 400 mb 2 : ext2 - 1600 mb
i got problem using link2sd because it tells me that it's not supported because i got a primary ext memory that's emulated from my internal memory.
i read on internet that i can exchange the emulated memory using a script like :
mount -o remount,rw /
mount -t vfat -o umask=0000 /dev/block/vold/179:61 /mnt/sdcard
mount -o bind /data/media /mnt/sdcard/external_sd
chmod 777 /mnt/sdcard/external_sd
but i think this is only for certain phones , what could i do to use both the primary and sd memory on this phone ?
thanks for the answers !
I've been trying to swap sdcard on kitkat, but no avail. any Ideas about how to swap or even remove the internal sdcard?
been trying to remount with this script but it's black screen with force closes, maybe theres something wrong with it?
Code:
LOG=/data/swap.log
umount /storage/sdcard0
umount /storage/sdcard1
umount /mnt/secure/asec
umount /storage/emulated/legacy
umount /mnt/shell/emulated
umount /mnt/media_rw/sdcard1
mount -t vfat -o umask=0000,uid=1023,gid=1023 /dev/block/vold/179:33 /mnt/shell/emulated 1>>$LOG 2>>$LOG

I saw some build.prop tweak to swap them(without init.d or any other modification),try to find it in google.
P.S.-I found a way to mount sdcard(ye,4gb partition used in 4.2.2 ) partition throw ADB,but i need help to make init.d script... For now its work correct,no problems with Googleplay(installing apps),camera(save pictures without problems)...
hmm

not to bring up an old tread
But would this method work with any phone or tablet with kitkat on it? Because I'm trying to do the same thing
Guys, I'm completely lost in tutorials so pls help me I'm freaking out!
I'm trying to bring to life my mother's HTC Explorer so I installed CM11 (cm-11-20140316-UNOFFICIAL-pico.zip) using some yt tutorial .
It works fine and now I'm trying to increase the phone internal memory. But in vain :'(
I tried:
1) editing build.prop
Code:
persist.sys.vold.switchexternal=1
ro.vold.switchablepair=/storage/sdcard0,/storage/sdcard1
-> no change
2) Trying to execute the StorageSwap.sh
Code:
#!/system/bin/sh
umount /mnt/media_rw/sdcard0
umount /mnt/media_rw/sdcard1
mount -t vfat -o uid=1023,gid=1023 /dev/block/vold/179:97 /mnt/media_rw/sdcard0
mount -t vfat -o uid=1023,gid=1023 /dev/block/vold/179:8 /mnt/media_rw/sdcard1
-> not working! permission denied
Can someone pls share a proved and easy way to make this work??
