On my G1, I know that the internal flash memory is divided into several partitions used by the system. Running the busybox shell on a terminal emulator on the phone or through adb, I can run df and get the following:
Code:
Filesystem 1K-blocks Used Available Use% Mounted on
tmpfs 48852 0 48852 0% /dev
tmpfs 48852 0 48852 0% /mnt/asec
/dev/block/mtdblock3 92160 89048 3112 97% /system
/dev/block/mtdblock5 91904 77792 14112 85% /data
/dev/block/loop0 4096 4096 0 100% /system/xbin
/dev/block/mtdblock4 30720 1160 29560 4% /cache
/dev/block/vold/179:1
15541688 12742232 2799456 82% /mnt/sdcard
/dev/block/vold/179:1
15541688 12742232 2799456 82% /mnt/secure/asec
But strangely there's no mount point for /, the root file system. Yet there are lot of other files and directories directly in the root file system, like init scripts. Could anyone explain to me how this is? Is the root file system hidden somehow from df?
Hello xda hackers,first off I'd like to say this is my first post here but your forums (and forum members work) has helped a lot.
I've recently been experimenting with xfs for my "sd card" on my nexus s.
(just to see the performance difference between xfs,fat32 and ext4 on my nexus s)
I've successfully compiled mkfs.xfs for arm and I’ve successfully formatted my sdcard storage with xfs. I’ve even gotten it to mount fine in android (btw, i use a custom kernel based on netarchy's git repo). i can verify it's mounted(i've even gotten it to mount at boot because vold.fstab just wasn't working). and i can even access files on it using some file browser apps.
the problem I'm having is that all of my apps think i don't have "external storage".
I've even done setprop EXTERNAL_STORAGE_STATE mounted
camera,music,etc.... all the apps say i don't have usb/external storage.
so i just wanted your help in finding out how exactly android tells if a mount-point is external storage or not.
FYI: my nexus s doesn't really have an sd card it's an internal storage (i think nand).
here is the output of some commands in case you need it:
adb shell mount:
Code:
rootfs / rootfs ro,noatime 0 0
tmpfs /dev tmpfs rw,noatime,mode=755 0 0
devpts /dev/pts devpts rw,noatime,mode=600 0 0

none /sys/kernel/debug debugfs rw,noatime 0 0
adb echo $EXTERNAL STORAGE :
# echo $EXTERNAL_STORAGE
/mnt/sdcard
feel free to ask me for more info. and yes I’ve googled it all over and plenty of people have tried helping me on irc. all the topics that come up is about people having their sd cards not detected.
mkfs.xfs in case anyone wants it.
oh, and I’ve attached mkfs.xfs for those of you who want to run it from your phones but don't want to compile it from the source(it took me a few hours to get around some of the compilation/cross-compilation issues).
it's 1.8Mb because it's statically linked.
nvm, i got is solved by hacking around vold. thanks for all the help...Not.
i cant mount sdcard storage
hi i have samsung galaxy 3 i5800

I have p3100 8GB and I saw that internal storage is only 2GB. is this normal? if not, what should I do?

It is 8GB total between all items stored. You have /data, /cache, /sdcard, /system, and then a couple other random items as well. The total of all of those should be ~8GB.

But isn't 2GB too low? Its only 2GB and I cant instal apps to sdcard.
sorry for my bad English.
I have about 3gb of storage not counting the space my apps take up.

Tab2lite beta 2
Storage lists my total space at 4.6gb.
Sent from my GT-P3113 using XDA Premium HD app
The memory layout on the Tab 2 is a strange bird. The 8GB is divided into two partitions of equal size, and you will always see the internal memory and virtual SDCard being of equal size. You really only have 4GB to actually install anything programwise. With Ice Cream Sandwich, you cannot move apps to the ExtSDCard because of Google's far-seeing "wisdom" that said that we would not ever need more than what they gave us in the Tab 2. There ARE some apps that will allow you to move some game files to the ExtSDCard like GL to SD(Root) and Directory Bind, but there really isn't a long term solution yet on how to move apps to the ExTSDCard consistently without need of special apps. I imagine that it may take a major ROM tweak that will allow this function. There is also a 1GB dedicated cache directory that needs to be cleaned ever so often otherwise Google Play will not allow you to install anything once the cache is filled. There are a number of utility apps available in the Play Store that will optimize memory and clear the cache...

So what should I do to get 4GB free space instead of 2GB ?

This is not right.
There are several partitions of the 8gb flash memory, not two. Not being able to move apps to an sd card is not an ICS issue but a modification made by Samsung. The cache never needs to be cleared, its size is 688mb not 1gb, and if you want to clear it (even though it offers no benefit whatsoever to do so) you can do it from the menus in ICS.

Do you have a terminal emulator app? adb? It's hard to fix your problem if we don't know more.

Yes I have terminal emulator app.
I have similar problem. I have p3110 16Gb and after installing Tab 2 lite beta 2 (I tested all other p3113 rom,stock and custom, and they all worked without any problems), memory went from 16GB to 8G. I can't find a way to revert this(installed the proper stock rom). One other strange thing is that i can't re-partition anymore using odin,it fails on that process. Any ideas?

I wonder if this will work without busybox but you should run
$ su
then
# fdisk -l /dev/block/mmcblk0
then
# df
also
# mount
and tell me what you see.
It would also be helpfull if you could go to the '/dev/block/platform/omap/omap_hsmmc.1/by-name/' directory and tell me what you see.
For the guy that flashed tab2lite, you should proabably pm the dev and ask him for an odin flashable partition table for the 16gb version.
This is what i get.

You have the 8gb model and a custom rom. How did you flash this? I heimdal or Odin? What ROM are you on?
Your /data partition is messed up.

We can close this threat. I solved this problem myself. Formated data and cache and now I have 4.56GB of space. THank you matt30 for your help!!!
HI Guys,
I have a peculiar problem, and I hope someone can help solve this:
My phone is a Galaxy 3 (I5801), and I just installed Kyrillos ROM 10.6 on it. I had previously created a 1GB ext4 partition using CWM in my 8Gb card. From Kyrillos' post, I only have to do this much to enable hybrid data2sd, where all the new apps get installed in the sd-ext (1gb) partition on sd card. It seemed to work fine, I removed unwanted launchhers, made backups using Titanium, and plugged the phone to My Linux Mint system.
I copied data to the sd card (6.x gb partition) (and the 1gb ext4 partition was also auto mounted).
I rebooted the phone, and all the newly installed apps (which went to sd-ext) were not visible anymore. I tried to find them, but they were visible as ghosts in the applications list in settings.
I am guessing that the ext4 partition is not getting mounted.
Why is this happening? any ideas? please help!
EDIT:
Here is the output of the "mount" command from terminal emulator

Any Ideas?
I have (almost) the same problem. My data2sd isn't working. link2sd desn't see my partition at all. And if I try to use hybrid data2sd I have to use it with either "g3mod config" or KMApp, but then I have this issue with ghost apps.
My phone is i5800, and if I enable BLN in KMApp (which is only for i5801), the apps stay normal, but I get sleep of death issue with screen.
I have compiled android 4.2.1 from mediatek offical source code for MTK6589, kernel and module port from official firmware . boot ok,basically works,but a big issue: the internal and external storage has 0 B left.
