file partioning MTD has changed in CM 11 4.4.. lets wait for our great developers to find out a proper way for swapping memory.

Use script manager to execute this script at boot..
For GalaxySL = i9003
#!/system/bin/sh
umount /mnt/media_rw/sdcard0
umount /mnt/media_rw/sdcard1
mount -t vfat -o uid=1023,gid=1023 /dev/block/vold/179:49 /mnt/media_rw/sdcard0
mount -t vfat -o uid=1023,gid=1023 /dev/block/vold/179:1 /mnt/media_rw/sdcard1
Can't be installed inside "init.d" folder.. Suggest to use /data..
Replace the id = 179:49 and 179.1 according to your device internal and external id.You can check them by executing the command:
mount | grep sdcard0
and
mount | grep sdcard1
to swap change the id.. change the sdcard0 id to sdcard1..

I am currently trying this http://forum.xda-developers.com/showpost.php?p=48876834&postcount=472
so far so good but havent tested it much, i think games run slower..

[Q] How to mount chosen partition as EXTERNAL sdcard

Hey,
didnt find answer in similar threads (spent already 1 day at this)
how to mount partition of my choice as an external sdcard? Currently my phone sees external SD card as unavailable because it had corrupted internal memory and i swapped it and whole system starts from true external sdcard.
i tried adding last line in fstab but no luck
fstab:
Code:
/dev/block/stl11 /cache auto rw
/dev/block/mmcblk0p2 /data rfs rw
/dev/block/stl10 /datadata auto rw
/dev/block/mmcblk0p3 /emmc fat32 rw
/dev/block/stl9 /system auto rw
/dev/block/mmcblk0p1 /sdcard auto rw
/dev/block/mmcblk0p4 /sdcard1 auto rw
vold.fstab
Code:
# sdcard mount for the P1
# internal sdcard
{
ums_path = /sys/devices/platform/usb_mass_storage/lun1/file
asec = disable
mbr_policy = overwrite
}
dev_mount sdcard /mnt/sdcard 1 /devices/platform/mmci-omap-hs.0/mmc_host/mmc1
# externel sdcard
#{
# ums_path = /sys/devices/platform/usb_mass_storage/lun1/file
# asec = enable
# mbr_policy = overwrite
#}
#dev_mount sdcard1 /mnt/sdcard/external_sd auto /devices/platform/mmci-omap-hs.0/mmc_host/mmc0
i commented here because it made no difference what i mount as external sd card, couldnt make it work.
Yes i have root and know adb enough to edit these files.
Please help.

find out FUSE mountpoints

hi guys.
i'm developing the gentoo extractor of dSploit and i've found a problem.
now that user can choose a custom directory for the gentoo root,
we must ensure that we can make symlinks in that folder.
from android 4.2 and above, the storage infrastructure uses FUSE.
create symlink where the ext FS is mounted on is fine.
create symlink where the FUSE is mounted on will fail.
Code:
[email protected]:/ # ln -s /system /storage/emulated/0/gentoo/test
link failed Function not implemented
[email protected]:/ # ln -s /system /data/media/0/gentoo/test
this happens because /storage/emulated/0 is a fuse bind mount of /data/media/0.
i think that the solution is to find what is mounted where and how.
how can i get FUSE mounts ?
/proc/mount will show /dev/fuse as source block device.
i need to have something that say:
Code:
source destination
/data/media/0 /storage/emulated/0
in order to replace "/storage/emulated/0" with "/data/media/0" and got symlink to work
thanks in advance for any help and suggestion.

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
