How to check if Compcache is enabled?

I am running Cyanogen 4.0.4 and would like to know if compcache is enabled. Can someone confirm if my settings are alright?
I have the following details:

if the only thing you have is compache and no linux-swap then compache is working because of the output from the free command

else you should be able to run the following with superuser access through terminal:
sh /system/bin/swap -s
It will show you the pre and post compression data size, as well as the compression rate under compcache.

Or simply use
Code:
# cat /proc/ramzswap
This file only exists when compcache is currently active. You will see its current settings and status:

[Q] Busybox install issue

Hi all, i got a SGS branded H3G, but already rooted.
When i try to install Busybox, it says i have no needed room in my /system folder, i do not have installed anything there before.
Then, i ran adb shell, su, df , and got this:
/dev: 166708K total, 0K used, 166708K available (block size 4096)

/efs: 6064K total, 4106K used, 1958K available (block size 1024)
Hey, it's true..only 784k. How can it be? how can i solve?
Anyway, also, some command line at adb wont work, as for " du -sh *", i got this:
$ su
su
# du
du
du: not found
# cd /system
cd /system
# du -sh *
du -sh *
du: not found
# du
du
du: not found

wtf

weird, did you do the lag fix?
did you repartition anything?
make sure you have disk space
i see you are rooted, just root it again, just in case
most root update.zip comes with busybox already, are you trying to upgradE?

No lag-fix installed, only clockworkmod recovery.
Yes, i'm rooted with superuser v. 2.3.5 and su binary v. 2131 ef (last one, but no busybox package inside) and i got 3gb disk space available :|
Also, no-repartion was done, it's still branded with original firmware

Any ideas ?

Gingerbread ROMs not playing nicely with Dark Tremors apps2sd?

SOLVED.
Used another SD card that wasn't partitioned and everything works fine.
MM Gingerbread and PhoenRom both cause me to not be able to install/update/restore apps due to insufficient storage even though there is plenty of space.
If I go back to CyanogenMod everything works fine.
My SD card is partitioned 7GB Windows/1GB Linux.
Going into Settings/Applications/Downloaded shows "72MB used / 124MB free"
On SD card shows "3.2GB used / 3.3GB free"
I currently have the PhoenRom installed, this is what df now shows:

When wiping user data in recovery I get the message
E:Can't mount /dev/block/mmcblk0p2 (or /dev/bloc/mmcblk0)
(Invalid argument)
Error mounting /sd-ext/!
Skipping format
I don't know if this is significant.

Hi. I have same problem on LG Optimus One with Android 2.2.1 ... how you solve that?

So don't partition
From your brief description of "Solved" ... it sounds like you just grabbed another FAT32 formatted SD Card and just put it in. No partition setup. However from reading other posts on DarkTremor's apps2sd ... you MUST have an EXT3 formatted partition in addition to the FAT32 partition in order for apps2sd to function.
From my understanding, since the Android OS has no problems running apps from EXT2 and EXT3 partitions ... the trick is that the apps are actually moved to the FAT32 partition and shortcuts (a.k.a. links) are put on the EXT3 partitions. This tricks and Android OS into thinking the apps are installed on EXT3 and not FAT32.
Unless I am just totally missing how this works.

Low Space / Memory even after a hard reset

Hi
I recently acquired a Nexus One that I'm having memory issues with. I'm running Gingerbread 2.3.4 (GRJ22). I've tried all sorts of options in erasing / clearing memory. After each of these attempts, it always only shows 13MB free. No extra applications are even installed!
I've done the following:
* Factory Data Reset
* Clear Storage during HBOOT
* Wipe data/factory reset during RECOVERY
* Wipe cache partition during RECOVERY
Any other ideas? I've recently rooted it too.

What does it read if you do
Code:
df -h | grep /data
in the terminal? (The line is called a pipe and on the computer is located on the backslash key '\' and comes up when you use shift. I don't know where it is on the stock keyboard, but on swype, it is under the 'D' key if you use shift and long press on 'D'.

There is a possibility that your internal memory is filled with bad sectors.
As noted above, please post the output of the "df -h" command, so it'll be more clear.

I have 19.45kb free with CM7 + gapps only (edit - that is for /system and that too only 40KB free).
when I give that df command in terminal I get
/dev/block/mtdblock5 196.3M 41.1M 155.2M 21% /data
what does that mean?

Just do
df -h
and you'll see the headings...

filesystem size used available use% mounted
/dev/block/mtdblock5 196.3M 41.1M 155.2M 21% /data
so that means I have 155.2M free on /data.
that's good but my /system is only 40.0k free (cm 7 +gapps) only ..bad sectors?

I can't seem to install terminal thru the marketplace. I think the low memory is preventing any additional application installs. Is that possible?
Is there another method to access a shell prompt on the device?

im sure you can use adb so plug it in!

Doesn't CM7 already come with Terminal installed...check your app drawer.

What gapps are you using? Because CM7 on mine has 8.56MB free after having gapps installed and DarkTremor's a2sd. If you are using one of the gapps that adds gmail, maps, facebook, etc... then that is probably your problem. That is why we have the smaller gapps (and to have gapps that are independent of the screen resolution). All those separate apps can be downloaded from the market. The tiny gapps gives you all the apps and framework needed to get onto the market so you can download the other apps.
And yes, Terminal is normally included with CM7...
You should definitely have more free on /system on a CM7 install with gapps.

How much is CM 7 + gapps from CM team on the /system (coz I use gapps which has gmail etc).

I don't know as I also have DarkTremor's a2sd installed, but I still have over 8.5MB available... so I would guess just over 10MB free.

I had low space problems on my old Eris. I just rooted & installed GingerShedBread (CM7) & have over 100MB free after installing 45 apps to internal storage.
GSB also supports moving all apps to sd including system.

I've just done some partition tweaks and now have 200+ apps with 118 mb free... xD

That is weird that the -h option isn't working. It works on mine. Anyway, I guess it is the default with the df command (designed to show things in MB or GB instead of just bytes).
Now we will figure out what is using all the space in your /data directory.
Code:
su
cd /data
du -hd 1
This will show a listing of your data directory with sizes next to each folder. Normally the data and app directories will be your largest (maybe app-private if you have a lot of private apps installed). You can cd into each of the directories and run the same command and if you add "| grep M" it will only show items that have a capital 'M' in it which will show you all the files that are rated in MB vs KB.
So the command would read
Code:
du -hd 1 | grep M
Hopefully you can then figure out what is taking up all your space.

It appears that I have bad sectors. The actual total size of /data is less than what shows up in "df". Any ideas on how I would repair the bad blocks?
I was able to run Ubuntu and get my Nexus One recognized by it. How do I fix the nexus one /data partition from Ubuntu? I'm assuming I would need to mount it.
I'm able to mount the /sd partition but can't see the other partitions. GParted only sees the SD partition as well when its attached with USB Storage turned on.

I don't have my Ubuntu box to confirm, but you should be able to mount /data as rw through adb (you only need the Linux adb, not the whole sdk).
Should look something like:
$ adb-linux shell
$ su
# mount /dev/block/mtdblock5 /data yaffs2 rw
...I'm sure someone will correct me if I'm wrong.

I will try this when I get home. But when you execute the mount cmd above, wouldnt that just mount the partition locally on the nexus one?

Yes it would mount it locally. I don't know if you would be able to mount the data partition onto the computer due to it not passing any disc info other than the sdcard. But, while in adb, you could try and run an e2fsck. I am not sure on the exactness of these commands, but I think it would be something like this in adb while in recovery.
Code:
adb-linux shell
mount system
e2fsck -pcfv /dev/block/mtdblock5
You may need to issue an 'su' command, but I think when you use adb it automatically logs in as root.
