[Android Q&A, Help & Troubleshooting] dutchpatriot:
Hi all,

I've been looking around to solve my /cache problem of it being only 17MB.

Found a temporary fix but that needed to be implemented or executed every boot up.

And since I am to lazy or stupid to remember that every boot I search for another solution :confused:...

Combined a script from someone else with some stuf I found somewhere else...

Descriptions are in the code....

This code works on my samsung I9000 with Full Advance Rom final 6.0.1:good::good:

#!/system/bin/sh

# Works on Full advance Rom with I9000
# Change params
# Check your partitions name /cache
# Need to be root via ADB or root via device
# with the command : mount
# This fix is only needed when /cache has arround 17mb!!!
# run this command as root in ADB shell as root
# To be able to execute this you need to change file system from read-only to rewritable
# as root exec this command: mount -o rw,remount /system
# Paste this text in a file called cachefix.sh
# command : vi cachefix.sh
# If you like me, and arn't that good with vi
# I will attach a cachefix.sh to this post as
# cachefix.txt rename it to cachefix.sh
# give the cachefix.sh the right permissions
# chmod 777 cachefix.sh
# Run this once!
# sh /LOCATION_OF_SCRIPT/cachefix.sh
# or
# ./LOCATION_OF_SCRIPT/cachefix.sh
#
# when ran once the /data/local
# and all went well has a
# cache.img file
# This is now mounted as /cache
# command to see or verfy: mount
# /cache is now as big as you made it under
# CREATE A FILE 500mb
# Every time you reboot the 99Tcachefix script in /etc/init.d/ will be executed!
#
# adb root
# adb shell

# remount / and /system writable
mount -o rw,remount /
mount -o rw,remount /system

# EDIT the right old cache partitio /dev/block/mtdblock3 to fit yours!!!
# Makes script in /etc/init.d named 99Tcachefix so it will be executed on boot
echo "#!/system/bin/sh \n umount /dev/block/mtdblock3 \n losetup /dev/block/loop7 /data/local/cache.img \n mount -t ext4 /dev/block/loop7 /cache \n chown system.cache /cache \n chmod 770 /cache" >> /system/etc/init.d/99Tcachefix

# assign the right permissions to be executed as root but not edited
#There is a very neat trick in every Linux which will allow you to do so. It is called the SetUI bit.
#Keep in mind that you will need to have the permissions locked down tight in this file for this to be secure.
#Make the file owned by root and group root:
#sudo chown root.root <my script>
#Now set the SetUID bit, make it executable for all and writable only by root:
#sudo chmod 4755 <my script>
# Keep in mind if this script will allow any input or editing of files, this will also be done as root.
# source https://askubuntu.com/questions/167847/how-to-run-bash-script-as-root-with-no-password

# Leave as is!
chown root.root /system/etc/init.d/99Tcachefix
chmod 4755 /system/etc/init.d/99Tcachefix

# Check if dir is there else Create Dir LEAVE AS IS
if [ -d "/data/local" ]; then
echo "directory /data/local already there!"
echo "Showing dir /data/local"
sleep 3
ls "/data/local"
sleep 2
else
# create dir
mkdir /data/local
echo "Directory /data/local created"
fi

# create a file 500mb (change if you like count=XXXXXX)

dd if=/dev/zero of=/data/local/cache.img bs=1024 count=500000

# create ext4 filesystem LEAVE AS IS!!
mke2fs -F -T ext4 /data/local/cache.img

# my cache partition is called /dev/block/mtdblock3 see whats yours is called and
# change this to yours!!!
umount /dev/block/mtdblock3

# mount LEAVE AS IS!!!
losetup /dev/block/loop7 /data/local/cache.img
mount -t ext4 /dev/block/loop7 /cache
chown system.cache /cache
chmod 770 /cache
# Remount / and /system as read-only again
mount -o ro,remount /system
mount -o ro,remount /
sleep 3
echo "Now after reboot this (cache) partition will be back!"
sleep 10
echo "All done, if there where no errors you can now delete cachefix.sh"
echo "If your new /cache partition is mounted with the given size than all is good"
echo "These are the configurations now"
# exec df command to show config now
df
sleep 10
exit

With this your /cache will be changed to whatever values you give in the code...

For safety remove the cachefix.sh afterwards...

Added cachefix.txt, download and rename to cachefix.sh

Greets,
