cp: write error: no space left on device in system

I have been having this error message come up using the terminal. I was attempting to add the volume enhancements via Lucid's script on the hybrid JF 1.51 with the HTC apps. I have asked Lucid if he knew how to solve this, but i wanted to see if anyone else might know the solution. I have been searching on here and also on google and yahoo but I have yet to find anything. I even took out my sd card to see if that would help after restarting my phone but nothing. Did i just screw myself?

i'm not privvy to lucid's script, but..
remount /system rewrite
do a cp -f to the files you are replacing
remount /system read-only
if you still get no space left, reboot your phone, then try again.

forgive my ignorance but do I type this in terminal as is? Because when I do that it cannot find remount.

I think I found the problem as to why I saw that error. I went from JFs-1.51 US built to the hybrid one that cyanogen did (the JF-1.51 + HTC apps) and I think there maybe something wrong inside there. First wiped and flashed JF's one and then wiped and flashed the cyanogen one and the problem is there.

copy the three files needed for the volume increase (2 if your on JF (AudioFilter and AudioPara4)) on to the sdcard in to lets say a directory named 'audio'. make sure you have unmounted the sdcard from within your OS after you have completed the copy, and have unplugged the USB cable.
open up terminal (on your phone)
$ su
# mount -o rw,remount /dev/block/mtdblock3 /system
# cd /sdcard/audio
# mkdir BK
# cp -p /system/etc/Audio* ./BK
# cp -f AudioFilter.csv /system/etc
# cp -f AudioPara4.csv /system/etc
# cp -f AudioPara_TMUS.csv /system/etc
# mount -o ro,remount /dev/block/mtdblock3 /system
# exit
$ exit
bounce your phone.

Thanks for the reply. I am still getting the same error with the JF-1.51+HTC apps build. I told Cyanogen about it and hopefully he will get it sorted out because his built is faster than the regular JF build. I guess I have to decide if the added HTC apps are worth more than the sound increase.

need write to /system or something EXEC path

I was the first person I know on the internet to compile nmap for android and this guy ( http://wjholden.com/nmap/ ) took it to the next level got a new phone ( CM6 with OC ) nbow it does not work
* can't write to /system even with rw remount
* if I boot recovery I can' write to /systm but its just a temp fs so failsause ...
* can't ADB shell (read below ) to find out where system is really mounted OR mount the real /system my self ..
* remouted / but anything I add gets wipped on reboot ...
* onlything that works is remount / , copy nmap and then add PATH hackery to EXEC nmap ... on EVERY reboot ...
NOTES BELOW:
Code:
http://forum.xda-developers.com/showthread.php?t=701589&page=4
I think its because /system is protected in CM5+ ? even with remount
command... ?
let me know what I need to copy where in recovery mode to /system to
get yours to run properly :/
you could also have your installer check for this and have notes etc ..

You can't write in /system in normal boot mode as security is on (s-on), remounting rw does you no good.
In recovery you will need to mount /system from clockwork before you can do anything.

I do have Clockwork Recovery 2.5.0.1 but I am not sure how to get to a shell and or find /system mount path as I can't adb shell ( read above ) so I can't remount or mount /system
rmccurdy.com/nmap.sh * this is what I am using for nmap as of now ..
Usage:
bash -x /sdcard/nmap.sh localhost
etc ...

There's an option in clockwork under partitions to allow you to mount the system. I'm not sure why but a lot of people have an issue getting into su with adb when they are in recovery, the constant /system/bin/sh error is annoying. Also, if I remember right, yaffs2 is not what you use to mount the system when using that command. It's mtdblock3 or something like that if I'm thinking along the correct lines here.
Maybe you should try putting it in a zip file as a script and running it that way since you use a different command (and much easier) to mount the system and write to it. Then again, I'm not sure what you're trying to so so I could just be talking out of my a$$

I can't do anything usefull in recovery ... reboot and apply update.zip but I dont how how nor do I really want to make a .zip / script to mount system etc .. do you know a zip I can work from as an example

The slide doesn't have S-Off, most HTC phones have them now...So you have to wait for Alpharev 2.0 to be released.

Yes, but in recovery we can mount the system and write to it. Phones with s-off can do that while booted normally because the NAND is unlocked and the system is no longer protected.
You can do it one of two ways. This one is easiest if you know linux commands but are unfamiliar with update-script format. Make an update script and put this in there:
Code:
show_progress 0.5 0
run_program PACKAGE:example.sh
show_progress 0.5 10
You don't have to use the show_progress line, it's just for aesthetics.
Make a .sh script, name it whatever you want and put the linux commands you want to execute in the script. For example:
Code:
#!/sbin/sh
#
##############################################
mount /system;
rm -rf /nmap
mkdir /nmap
echo 'export PATH=$PATH:/nmap' > path
cd /nmap
wget http://rmccurdy.com/stuff/G1/BINS/NMAP/NMAP.zip
unzip NMAP.zip
chmod 777 /nmap/*
export PATH=$PATH:/nmap
echo run /nmap/path before you start nmap
nmap -vvv 127.0.0.1
exit 0;
Or what ever you're trying to get done. I'll upload an example file of all this since hands on is always better. Looking at this though, you may want to have the files in the zip (in the directories they will be installed to) because wget probably wont work since the radio is off while in recovery.

interesting thanks ! ... do you have to resign it and all or can you just edit and rezip it ?

As long as you're using clockwork you just edit and zip. Might be easier to use an archive explorer to open (without uzipping it) then drag and drop, but do what's easiest for you.

Why 'adb remount' failed on a Rooted neuxs one

Hi,
I have rooted my Nexus one. I can do "'adb shell and then 'su' under the shell"
But on my MacOS Desktop, when I execute 'adb remount', it still said
$ adb remount
remount failed: Operation not permitted

Can anyone please help me resolve this?
Thank you.

[size=+4]DO *NOT* POST QUESTIONS IN THIS FORUM - only tips/info/etc.[/size]
Right at the top. Why does this have to be repeated on a daily basis?

Can you please move my thread to the right forum? I can't find a way to do it.

Anyhow, to answer you question... you "adb remount" is disabled in production releases... just rooting does not allow this.
You need a modified boot image where ro.secure=0 in default.props, instead of ro.secure=1. The ro.secure flag in the boot image indicates whether the root filesystem can be remounted as read/write... 0 indicated it can be... 1 indicated it cannot be.
If ro.secure=0, this is referred to as insecure boot.
Most custom ROMs have this by default... some rooted stock ROMs do not have this...

Will the Modified GRI40 (2.3.3 Gingerbread) ROM from this
http:// forum.xda-developers.com/showthread.php?t=968396
Does what I need? Thanks.

Or you can also use these commands to mount and unmount the system partition as writable:
Code:
mount -o remount,rw /dev/block/mtdblock3 /system
mount -o remount,ro /dev/block/mtdblock3 /system

Thank you. That seems to be an easier solution for me.
But after I did
$ adb shell
$ su
# mount -o remount,rw /dev/block/mtdblock3 /system

Don't try to combine adb commands with shell commands.
Copy/move/push the file to your sdcard first.
Then open a root shell, mount it as rw, then copy the file from your sdcard to the directory you want.

Thanks. but I get 'failed on '/sdcard/sqlite3' - Cross-device link'

I get the 'sqlite3' from SuperOneClickv1.7-ShortFuse.zip.

Wholly crap, don't use the mv command! Bad idea!!! mv does not move the data, it moves the hardlink to the data! Thank your lucky stars mv wouldn't let you do it.
Use cp instead. cp will actually copy the data to where you're going.

Thank you. But I don't have 'cp' in my adb shell.

How do you have mv but not cp? Do you not have BusyBox installed?

No. I just need to search 'BusyBox' on Android market and install it? That is?

The cat command will work fine, no busybox needed: cat source_file > dest_file

Woah there partner. Cat shouldn't be used on binary files, only ascii files. While it might work fine, it is not the recommended practice and really should not be done.
OP, Yes, BusyBox can be installed from the market.

On standard Unix/Linux/etc. systems, cat works fine for binary files. It's only under DOS that cat or type shouldn't be used for binaries.

[Q] /system/bin 100% full?

Hi,
I unrooted and ran the 4.5.141 update. I'm now on Android OS 2.3.6. I am now trying to follow the directions to re-root from here: http://www.android-advice.com/2012/root-the-motorola-atrix-4g-running-4-5-141/
However, when I get to the step where I run the command:
Code:
cp /preinstall/su /system/bin/
I get the error "cp: write error: No space left on device" which I thought was very odd....so, I ran the command
Code:
df /system/bin
and the output I see is:
Code:
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/block/mmcblk0p12
326071 326068 3 100% /system
Is this possible? How do I get su back on to /system/bin?
How can it be that the /system partition is full? Is there a way to resize it, if that's the case?
Please help!!!

did you do step 6 before step 4
check this out THIS

Obviously, otherwise it won't work. My problem is that /system has no free space. How is that possible?

a simple 'yes', without 'tude, would have sufficed.

Ok, here's what I had to do to make this work. First, you have to check if you have Superuser.apk saved in /system/app. If you do, delete it (you'll reinstall this later).
Since I also wanted to install the latest version of Swype, first, rename /system/lib/libSwypeCore.so to /system/lib/libSwypeCore.so.bak
Then, cp /system/app/Swype.apk /sdcard/Swype.apk.bak
After you've copied the stock Swype to the sdcard, then rm /system/app/Swype.apk
This should provide you with enough room on /system to cp /preinstall/su /system/bin/su
The rest should follow accordingly.

[QUESTION] About the source code of supersu/suid

Hi to all,
I would like understand the process about root on my s4 i9505.
For due this I have opened the script of CF-Supersu I have found some part that I don't understand.
Before write more about it, I have another question.
I would like also understand why, if I copy the binary SU from CWM (that has a root access thought adb) into the folder /system/xbin and I set to this binary the right permission, when I call this binary from the application terminal into the system I haven't root.
About the second question, looking the source code of supersu script, I have found some command that I don't understand.
First:
Code:
su --install
Second:
Code:
cp $BIN/su /system/bin/.ext/.su
cp $COM/install-recovery.sh /system/etc/install-recovery.sh
ln -s /system/etc/install-recovery.sh /system/bin/install-recovery.sh
cp $COM/99SuperSUDaemon /system/etc/init.d/99SuperSUDaemon
echo 1 > /system/etc/.installed_su_daemon
Third:
Code:
/system/xbin/supolicy
LD_LIBRARY_PATH=/system/lib $BIN/[B][U]chattr[/U][/B]$PIE -i /system/bin/su
Fourth:
Code:
#!/system/bin/sh
/system/xbin/daemonsu --auto-daemon &
Could someone please help me ?
Many thanks to support.
