symlinks and /mnt/sdcard

What filesystem format is the internal memory that's presented as /mnt/sdcard? If it's EXT4 can you link from it to /mnt/external1 that's formatted FAT32?
The reason I ask is I have an RSS client that will only save its cache to /sdcard but I have more saved content from my old phone than will fit in the internal memory (by about 2x) and I was thinking of rooting to be able to do a symlink between the directory on /sdcard and the external card.

This sounds interesting, I've got an app or two that default to sdcard even when I change their preferences to external1, would be a good way to make them use the right location without having to navigate to it each time.

Here's what it says on mine from the output of 'mount'

Well, it turns out symlinks don't work on the locally hosted /sdcard due to Fuse. However there IS a solution. I ended up using this tool to do a directory to directory mount. It's quite a hack, and when combined with the chroot Debian install I did on my phone makes my mount table a million lines long, but it does work =)

How to verify 'discard' flag working in fstab.cardhu?

I have TF700 running Crombi-KK F2FS on data, and added the 'discard' flag to fstab.cardhu to (hopefully) ensure trim of flash memory. Is there some way to verify that the discard function is working?

The fstab,cardhu gets modified by my boot process depending upon what you chose. I intentionally remove the discard option as it cause me bootloops.
However to check if yours has persistd ( and it may have if you haven't been anywhere near data2sd or rom2sd) is run the following in a terminal
mount | grep /dev/block/*
look for the /data and you will see what options it has been mounted with, interested to see if discard has persisted and why it won't work on my device

You can't edit the fstab directly as it gets replaced by the kernel on every boot.
so go to /system/boot/print.d
Open 30fstab-f2fs in a text editor
On this line change it from
$BB sed -i '/mmcblk0p8/{;s/ext4/f2fs/;s/barrier=.,//;s/nodiratime,//;s/noauto_da_alloc,//;s/nomblk_io_submit,//;}' /fstab.cardhu
to
$BB sed -i '/mmcblk0p8/{;s/ext4/f2fs/;s/barrier=.,//;s/nodiratime/discard/;s/noauto_da_alloc,//;s/nomblk_io_submit,//;}' /fstab.cardhu
Reboot but be prepared for a bootloop that you can only fix by undoing what you just did.... Have a nandroid ready to go

Just a cautious check on syntax before I do this. Every other flag on that line is of the form: ;s/flagx,// , yet in this instance you suggest just forward slash after 'nodiratime', ending with just a forward slash instead of two forward slashes. Is this intentional or should the syntax be: //;s/nodiratime,//;s/discard,//;s/noauto_da_alloc, etc.
Although I've used linux for years (Since Red Hat 7!) and have just enough knowledge to follow instructions to edit scripts, I still don't grasp syntax very well. (Just enough to know if I get it wrong things screw up
Also, if I save a copy of the 30fstab-f2fs file to sdcard can I simply copy it back using TWRP (latest) instead of a full nandroid restore?
Sorry if these are dumb questions. Your help is greatly appreciated.

Yes it is my correct - my edit will replace nodiratime with discard Your edit will look for discard (which isn't there) and replace it with nothing
Personally I'd do a full nandroid but yes as long as you can partially recover then that single file should be ok.

Many thanks (red face here). I'll give it a try today and do the full nandroid backup just in case. Will report back the result.

Well! That was a debacle.:crying:
Changed to:
"$BB sed -i '/mmcblk0p8/{;s/ext4/f2fs/;s/barrier=.,//;s/nodiratime/discard/;s/noauto_da_alloc,//;s/nomblk_io_submit,//;}' /fstab.cardhu "
It didn't boot loop, but eventually booted into a screen which said, "Encryption Unsuccesful. Encryption was interrupted and can't complete. As a result your tablet is no longer accessible" etc....
Thank god for the nandroid! When I reflashed the nandroid, TWRP reported that it was formatting system to ext4 even though it was originally F2FS. However when I rebooted and checked in terminal it indicated that the FS on system was in fact F2FS.

No idea why, but its all working again, but alas, no 'discard' option. Could this be the reason?

What is the additional partition mmcblk1p2 for data? The partition mmcblk0p8 which on my system is my data partition has been located on /datai and is ext4 on yours. How does that happen? Are you using data2sd or something?

Yes, you are correct. I am using Data2sd. I am running f2fs on my external data partition (/dev/block/mmcblk1p2) and leave my internal data partition as ext4 because it is just a backup data partition that I actually never use it.

Ah! Mystery solved then. sbdags was right then that with internal F2FS /data the discard option will bootloop, or, as in my case boot and trash the data partition requiring factory reset. Hopefully, the F2FS file system and KitKat manage garbage collection well enough without fstrim/discard as I don't want to reinstall again as ext4 at this point. Perhaps someone will make it work in the future.

Hmm, I did help one user using f2fs on internal data partition with discard flag on JB Rom. He had no issue until moving on with KK Rom. If I can have the tf700 long enough, I will test it out on the internal data so we can rule it out...
Garbage collection is to reclaim your locked up or old memory that old apps keeps holding on without using them. I believe that is what it is for but I may be wrong...

[Q] Writing to exfat on Nexus 5 with ElementalX kernel

I'm currently using ElementalX kernel with built in exfat/ntfs and Stickmount for mount/unmount support.
I can mount and read files from exfat usb sticks as well as rename and delete. My issue however is when I try to create files. When I copy from internal memory to usb drive I get permission denied errors.
I'm trying to troubleshoot if this is the kernel, or some rom related issue. Would anyone know off hand if this is a limitation of the kernel or suggestions to remedy the issue?
I've already verified it is mounted writable and the phone sees free space

Plug the USB stick in with exfat. Open a terminal emulator. Type "mount" and press enter.
What's the output? Copy/paste please

I'm using sshdroid for remote terminal to root in. I have also tried using a terminal emulator on the device with the same results so I just stuck with using sshdroid for all my testing.

[Q] Problems to swap external sd to internal sd (kitkat 4.4.2)

Hi guys,
i'm sorry if i opened my question in wrong location.
I tried to swap my sd card external for internal in my device, but i don't have success.
I tried using Root External to internal using the following setup:
internal: /mnt/sdcard
external /mnt/sdcard2
device access: /dev/block/vold/179:97
and option: umask=0000
before the kitkat(4.1.2) the process successful .
I list my mount via adb and note that internal is mounted in /storage/emulated/0 and executed manual line on adb:
mount -o remount,rw /
mount -t vfat -o umask=0000 /dev/block/vold/179:97 /mnt/shell/emulated/0
apparently worked, i use "ln -l" on "/mnt/shell/emulated/0" with "root" and list external files, but without "root" not worked.
=/
after, i list "mount" and tried in all mounts that use "/dev/fuse" but not worked.
i modified platform.xml (http://forum.xda-developers.com/showthread.php?t=2687734) but not worked.
Below is the list of "mount" default of device:

[Q] Internal sdcard not mounted

Hi everybody,
I'm trying to port a 4.4.4 rom for HTC Sensation xl wich only have an internal sdcard. The rom boot but the internal sdcard is not mounted , whatever rom i use as base. When I use a 4.4.2 rom as base, i can't acces the internal storage cause it said that the folder is missing or doesn't exist. When I use a 4.4.4 rom as base, it said that i "need more permission" and the internal storage file is empty even if i can see all the files in it from recovery.
I've try these solutions to fix the problem but none of them worked :
1) Put the base storage file in port framework-res.apk
2) Put the base vold.fstad file in system/ect/ folder
3) Take the sdcard file from base bin folder to port bin folder
when I try to see what is mounted in terminal emulator, this is what i get :
[email protected]:/ $ su
[email protected]:/ # mount

But when i compare it with what i get from a rom with sdcard mounted, i can see that there's three lines missing at the end and these lines are about the sdcard

From a file manager i see that the 179:34 and fuse files are present in the rom wich doesn't mount the sdcard but i can't understand why the internal storage is missing.
For now, i really don't know how to fix the problem and i need your help.
