My rooted yp-g1 US running cm7 wouldn't let me download anything from the internet. Didn't think anything of it but when I tried to delete something from /sdcard or anywhere else it said it couldn't be deleted. So apparently I have a read only filesystem or something. Fix???

You could try this on the affected filesystems (as root, of course) :
mount -o remount,rw /sdcard
Sent from my YP-G70
Says it can't find /sdcard in /proc/mounts
Sent from my YP-G1 using XDA
Then you'll have to use /mnt/sdcard

Has anybody tried to run ntfs on Razr? Will it be possible?
Sent from my XT910 using XDA App
Do you mean external storage with NTFS? On my tablet I use an app for that.
I can release a kernel module for mounting NTFS partition on RAZR... I'll watch at it when I'll be back home (3hrs).
is this about getting a thumb drive to b mounted to the razr? If so can u make it foe he Verizon droid razr too....

Compiled.

Uncompress and insmod
Wouldn't we need to modify vold to be able to mount NTFS?
(ofc. you could mount it manually but...)
@pajn
Obviously. This was intended for manual mount.

I was just trying to mount an external ntfs drive tonight and ran across your post. Could you please explain how to do the insmod? Thanks for the help
su
insmod /path/to/kernelmodule
@kholk
Okey. Hopefully someone does that soon so we can mount any filesystem that the kernel supports with vold
Thx.........
Hi
What am I doing wrong

When you extract it, you should get "ntfs.ko".
I fill quite stupid. inmod command works for me, but I don't know how to mount external drive. I try something like mount -t ntfs /dev/block/sda /mnt/usbdisk_1.1 , it finished without exception, but usbdisk_1.1 was empty.
Any suggestions for noob?

Thanks kholk, now it's works. I can read from my external HDD.
It is possible also to write to ntfs partition? Cause it doesn't work for me.

I found that for Samsung galaxy s2 that copy ntfs-3g to system/bin. I suppose that we cannot do that while we have locked bootloader.
We have on our Razr /bin/ntfs-3g. It is possible to use this to have possibility to write to ntfs partition? If I try to run it, I get errors with missing fuse. If we have fuse for our kernel we could maybe use ntfs-3g.
Can anyone help?

I must use umask=000 to see something. I cannot use -t ntfs-3g it throws me Device not found. I try to use
mount -o rw,umask=000 -t ntfs /dev/block/sda1 /mnt/usbdisk_1.1, but still no writable access.
When I try
[email protected]_spyder:/# /bin/ntfs-3g
It returns
Mount is denied because setuid and setgid root ntfs-3g is insecure with the
external FUSE library. Either remove the setuid/setgid bit from the binary
or rebuild NTFS-3G with integrated FUSE support and make it setuid root.
Please see more information at http://ntfs-3g.org/support.html#unprivileged
From what I read, ntfs-3g don't need to be compiled to specific kernel version so we can use from sgs2 or maybe build one. But fuse is kernel specific.
Any idea?

Ok long story but I'm trying to figure out how to mount the external sdcard from a shell script or terminal emulator. Nothing I've tried or can find works. One example that's not working (or any variations of this) :
mount -o remount,rw /dev/block/mmcblk1p2 /mnt/sdcard/ext_sd

When you plug in just hit "use as external storage" or somehing like that when the window comes up in the phone.
Yeah I know how to mount ext_sd via USB I'm working on a script and need to know the command to use from a script, I'm not trying to mount the card on my computer.
Sorry I wasn't more specific.

That's what you wrote.
So, you want to be able to push or retrieve a file from external SD through ADB?
No not really, though I guess that would be similar. I'm working on a script and in the script I need to mount the external sdcard if it's not already mounted.

I jumped from stock to CM10 and have found an issue I need resolved, but am not sure how to go about it.
On stock, I didn't have
/sdcard/ is the path for the internal memory
/sdcard/external_sd/ is the path for the actual add-in slot you buy yourself.
This is great because the file explorer apps don't need special access to get to, and things are at least somewhat logical on how they're laid out.
On CM10:
/storage/sdcard0/ is internal memory
/storage/sdcard1/ is external memory
There are symbolic links of /sdcard and /external_sd but to access the latter, I need to tell apps like ES file explorer to change their base path rather than just having a nested mount structure.
I've tried using terminal emulator to go in and create a symbolic link, but I get 'operation not permitted' messages. I've also tried editing /etc/vold.fstab to have it change the mount from /storage/sdcard1 to /storage/sdcard0/external_sd, but the filesystem is read-only and 'mount -o remount,rw /' doesn't have an effect even though it doesn't complain.
How can I change the mount structure back to how I want it and how it's easier to access/navigate it in my apps?
Run into some situation, hopefully someone can shed some light

In my original post I mention trying to get it remounted as r/w, the command doesn't complain but the filesystem stays read-only.
Try busybox mount -o remount,rw /system
If that fails, use an app to do it.

Any particular apps to recommend? I had tried issuing the remount command on / and not /system. I will give that another try.

I was able to modify the mount point to be /storage/sdcard0/external_sd/ for the external SD slot, but when I rebooted CM it got stuck and would buzz every 10 seconds or so and stayed that way indefinitely. Not sure why this breaks CM so bad but there you have it. Oh well.
Might be a better idea to just add links so you get your old /sdcard/external_sd
I'm not currently on a CM10 ROM or else I'd test.

Symbolic links don't work on a FAT based filesystem (which the SD card mounts are), unfortunately.
1. Partition the SD with CWM (easiest method) and you can be sure that the second partition disk type is of ext4 (latest CWM).
2. Rename other scripts in init.d, so that it gets executed only after the mount script has run (prioritize mount script).
3. Ext4 has many advantages over its earlier versions. So update the mount script's disk mount type to be ext4 (mount -t ext4).
4. If you are using low performance SD please update the script to mount the disk without mount options such as noatime.
5. Never add ext4 tweak if you are using mount scripts, it causes data corruption.
6. If you don't want the script to move certain folders in data partition then add the folder name to the moving data to SD ext.
Using a mount script is very easy, these points make it better.
BTW, I suggest you to try INT2EXT for EXT4 (with the above updations) the next time you reset your device.

Ok finally i observed that u disabled noatime, norealtime and zipalign code from the original int2ext4+ script..but i still dont understand what does that code do
Code:
-o nosuid,nodev,noatime,nodiratime,barrier=0,nobh,data=writeback,noauto_da_alloc
BTW thanks nanba for all the help dude..

Those are the options available while mounting a disk. You can Google for each one, read the Linux pages.

I prefer reverse mount than symlinks and for speed I leave dalvik cache on data partition. You can try that too.

I always mounted images with (busybox mount $img /path) , but make sure your kernel supports loop devices and the img is formatted to ext4 (mke2fs -T ext4 $img)
