Weird memory readings..need explaining

Hi i noticed that i only have 28MB of ROM left. Installed apps ~90. I mean ok i have 16 games but it's small ones no 3D.
AppManager says 28M free of 196?! what's up with that. I though we have 512MB. To be sure i opened up shell and did a top and df -h. Here are the outputs. What the hell is going on there?

RAM is also not shoing up as 512...although the device is rooted

CPU: 7.1% usr 21.4% sys 0.0% nic 71.4% idle 0.0% io 0.0% irq 0.0% sirq

after reading a different thread i found that different system compoents eat the rest of the ROM so we are left with ~200MB.
but what is mpfs__________________192.9M____0_____192.9M___0% /dev
Why is this not used at all?

There is no fix for the 196MB /data partition limitation yet. Your only option is to use apps2sd (after rooting). I have it set to 768MB on my SD card

thanks for the reply.. but still if i use apps2sd i won't be able to chose where to install an app.. right?

actually there is an option in the newest CM that allows you to turn on and off Install to SD so yes you can choose.

Its either /data or /sd-ext/data. CM adds this to the settings activity.
If you do decide to move to the other option, use titanium backup to backup to SD, then restore. It will automatically go to either /data or /sd-ext/data
Private data for apps is still stored in /data, but apps2sd does help in slowing down the filling of /data

thanks.. It's clear now.. sadly i`m not usin CM ROM since it has no smart dialing and some other stuff i cannot live without so i`m using the desire rom..
With the DESIRE being released momentarily i`m hope we get a cleaner/bugfree ROM.
Also i`m not sure what google is waiting for releasing a new ROM for the N1

[Q] Help! App2SD issues, SD apps disappeared & won't work!!

N1, rooted, 2.2, many apps to SD (both natively or using root).
Things have been humming along just fine. Today, after a reboot from a hanging app update, I no longer have access to apps that are loaded on SD. LauncherPro displays them using generic Android icons rather than the actual apps.
When I go to Manage Applications, they are listed but are all grayed out.
Several reboots, no joy.
Went to Settings/SD/. SD is shown as mounted. Tried to umount, the process hangs.
HELP!!
How do I troubleshoot/get my phone back to normal?
Is there a Linux "chkdsk" I can invoke?
I would really appreciate some help.
Cheers.
Edit: It appears that I can take pictures and browse pictures stored on SD, which suggests that the SD is mounted. What could be wrong?
Edit 2: From what I can tell, the link or reference to all the apps on SD is lost or corrupted. How do I rebuild/fix? HELP!!
Edit 3: Under Manage Applications, all the A2SD apps are grayed out. When I select one, the size information hangs at "Computing..." PLEASE HELP!!

Here is another clue: When I remove the MicroSD and boot the phone without it, there is no "SD missing" indicator on the notification bar. I thought there should be??
Without the MicroSD inserted:
The phone and the missing App2SD behave the same as if the SD were inserted except when I go to Manage Applications and select one of the App2SD apps, the file/cache/data size information show up right away (correctly). When SD is inserted, they hang at "computing size...".
Does this give someone a clue on what to do? Please?

Sounds like they are corrupt...
Just reinstall from the market.

Thanks. It would seem like not the individual applications, but rather the table or links to all the App2SD is corrupt. Is there a way to fix this without needing to reinstall everything? I have over 200 apps!
Moreover, does the 1) lack of "missing SD" when it is not inserted, 2) strange behavior when trying to umount the SD and, 3) hanging at "computing size..." under Manage Applications suggest a deeper issue? (All described above.)
Here is a lesson for having a good backup.

I've had this happen to me a few times now. I'm running stock, rooted 2.2.1 and am using the native app2sd functionality of FroYo. It occurs after a reboot. Shelling into the phone and doing a "df" to show mounts reveals that none of the normal application mounts are in place. Going to the /mnt/asec directory shows that each of the application directories exist but are empty. When things are working, each application's directory contains a "pkg.apk" file.
The only way I've been able to recover has been to use Titanium Backup to re-install each app from the back-up I'd made before this happened. I've become very paranoid and keep my back-up up-to-date at all times. Recovering this way is still pretty tedious, and I only have about 18 apps on my SD card. I'd think there'd be a better way to rebuild the /mnt/asec directory. I've created a tar of /mnt/asec and, if I have this problem again, I'm going to try just restoring the tar and rebooting to see if I can avoid the one-by-one reinstall.

Oh man I didn't want to hear that! Any idea what caused this? I saw it once before and things went back to normal after another reboot. This time, it didn't
Also, any idea why I am unable to umount the SD, no "missing SD" on notification bar when it is not inserted, and stuck on "Computing..." under Manage Applications when SD IS inserted?
Ugh!!
Edit: I'm Linux igorant. Is going to /mnt/asec simply as "cd /mnt/asec"? Also, what should I expect to see with a "df" and under /mnt/asec?

This is what I see with "df"

I then entered "cd mnt/asec", and "ls -a", but nothing at all was returned.
I cd'ed to /mnt/secure/asec and ls showed these (abbreviated):
android.tether-1.asec
bz.ktk.bubble-1.asec
<snip>
ymst.android.fxcamera-2.asec
ymst.android.homeswitcher-1.asec
They look like reference to the apps.
I have no idea what I'm looking at...

Trying to reinstall the apps, even on the phone rather than SD, does not work either. Is the only way to fix this to do a wipe/hard reset?
I'm really curious about what happened.

I get the same thing every time I reboot.
All I do is "Force Stop" LauncherPro then wait for it to start back up again and all my apps reload.
It may take more than one force stop, but 1 usually does the trick.

I wish it were that easy. I've seen the problem you describe, where certain App2SD apps or gadgets don't show up on LauncherPro properly. A restart of LauncherPro fixes it. Under that condition, they still show up properly in the Market and Manage Applications. You can still launch the app by other means.
In this case, I believe the apps are actually gone...

What you're seeing in the /mnt/secure/asec directory sounds normal. This directory wasn't altered by the problem when I had it occur, as far as I could tell.
Your description of the /mnt/asec directory is different than what I saw. It seems yours is empty. Mine had a directory for each app on the SD card, though the directories were empty, rather than having the pkg.apk files in them that they do when things are working normally.
I've always been able to re-install my apps, so your occurrence of the problem may be a bit different than mine. Are you able to install a new app and move it to the SD card via the standard FroYo method, for an app that allows this?

Thanks for replying. I pulled the SD, did a wipe last night. The SD has a .android_secure directory. In it, there is a file for each app that is installed on the SD. Each file has the .asec extension.
After the wipe, I reinstalled the SD and experienced similar problem as before: Can't dismount SD, installing app from Market hangs, etc. Titanium restore hangs too. Strangely, browsing to that directory using Root Explorer shows the directory to be empty.
It was when I decided to rename the .android_secure directory when everything returned to normal. The OS recreated the directory, app installation worked, and I was able to run a Titanium restore. Unfortunately, the backup is old.
I wish there is a good explaination to what happened...
Edit: Something interesting...
I did a "df" now that things are working.
I still saw everything I did yesterday (sizes a bit different):
/dev: 197552K total, 0K used, 197552K available (block size 4096)

(note that the /mnt/asec still shows 0k used.)
BUT NOW I ALSO SEE:
/mnt/asec/net.cdeguet.smartkeyboardpro.en-1...
and one for each app.
Was it that these apps were just not properly mounting, therefore the OS cannot "see" them?

Yes. It's what the post above is telling you.

What could have caused this? Was there a way to repair the issue without a wipe? Some way to get the apps to re-link or mount?

I was having the same problem on MicroMod. I boot into RA recovery and under partition sd I repair sd extension and upgrade ext2 to ext3 and that fix my problem. Hope that helps someone

I think i have a same problem but don't know how to fix it.
I used Titanium Backup to back up my files.
I copied these files to my external sd.
After this is did a hard reset.
After this reset the files were in the .android_secure folder on my external sd.
All the files have the extension ''asec''.
Can someone help?

I had this problem a while ago and the only way I got it to go away was to do a factory reset via clockworkmod recovery. Just today, the problem came back. What I've noticed is that after a few hours, the apps come back. I have read that this problem could be caused by corrupted files on the sd card. The only way to fix it is to format the sd card (and posibly partition it). I am planing on waiting until they come back, backing them up, backing up my SD and partitioning my sd card (which wipes everything on it.)

So regularly performing a backup image of the SD card would help someone recover from this problem?
As well, are all the phones that are having this issue using aftermarket SD cards?

few days ago I had corrupted App2SD function for 3 days.. during those 3 days I kept working to fix it and finally I had to format my SD card and reinstall all applications... it was kinda fraustrating.
But I notice that when I execute "move all apps from internal storage to SD card" on Titanium Backup, sometimes it gets stuck (when there are more than 140 apps) and all applications on SD card get corrupted.

I can only suggest to all those still stuck with default Froyo Apps2SD method, make a (long due) switch and move to DarkTremor's Apps2SD. The hassle is completely worth it.

HD2 Internal Memory

Despite all the posts and solutions on this subject I must admit a level of frustration at my continuing low internal memory on my HD2, I am running Pacman/ xylograph jb which has plenty of ROM space (most other ROMS take much bigger partitions), Link2SD, Apps2ROM and Clean Master. Link2SD tells me I have no apps on internal, Apps2Rom also confirms all apps either on ROM or SD.
When I look at the storage values I get:
Internal: 146MB used 106 free 40.1
SD card 10.98GB Used 3.91 Free 7.08
SD 2nd partition 3.81GB Used 30.3MB Free 3.77GB
System 260MB Used 177 Free 83.5
Cache 146MB Used 106 Free 40.1
Why is it that despite linking all apps to 2nd partition and having spare space on ROM my internal space is so low, cache is cleaned out every day.
What is using 106MB of internal space?
Any useful thoughts would be appreciated.

Your system partition is way too big, 260mb with 83.5mb free.
You don't need that, 185 mb should be fine for system partition.
Check out the rom thread for recommended partition size.

You can also run roms with DataOnExt. You won't ever run out of memory then. Format an ext4 partition of 1 to 2 GB on your SD card and you have plenty memory.
Or do you have a specific reason to run on Nand?

I agree with this.
DataOnEXT is definitely the best solution for problems regarding running out of memory quickly.

32gb - how much is usable for storage?

I have a S2 16gb with 11.5gb usable "usb internal storage". Will Htc One have at least 28gb?

It is fine in my opinion. Most of the apps you install goes into that occupied 6 gigs anyway

No, storage is unified: apps go in the 26. (I think).

Oh if that's the case it really don't make much sense. I mean what would they use 6 gigs for, I don't believe smartphones are getting that big updates.

26.1gb is free to be precise lol and 1.5gb RAM

source of your information?
If it has 2 partitions and one acts like the onboard (6gigs), and the other one (26) acts like a sd or whatever it would be ok ..
otherwise it's just like with the surface tablets .. well not quite as bad, but still a bit silly^^

If im correct on my HTC One X which was 32GB, i only had 22GB free after jelly bean update and 6GB or so for apps..
so the apps and sd storage is split

Got this from the stock recovery posted here on dev section when I extracted it.
Code:
# mount point fstype device [device2]
/boot emmc boot
/cache ext4 cache
/data ext4 userdata
/misc emmc misc
/recovery emmc recovery
/sdcard vfat /dev/block/sda1 /dev/block/sda
/system ext4 system
/devlog ext4 devlog
/reserve vfat reserve
Shows that /data(userdata) partition where apps get's installed has a seperation partition that needs to be mounted. So nope it's not unified.
and yeah for the developers who plan on extracting kernels/recovery of HTC One here are the info you need.
Code:
BOARD_KERNEL_CMDLINE is "console=ttyHSL0,115200,n8 androidboot.hardware=m7 user_debug=31"
BOARD_KERNEL_BASE is "0x80600000"
BOARD_PAGE_SIZE is "2048"

26 gigs is more than enough for me, I take up 5 to 6 on music alone and the rest on pictures and videos taken on phone, not much is taken with apps downloaded at the most 1gb so I'm quite comfortable with the amount of space on the phone although it would be awesome to have 28 or 29gb free
P.s. I do listen to all that music that takes up 5 to 6gb of space on my current phone in case some of you are wondering whether I listen to most of it wasting space on all that music

I think it would be possible to repartition the /system partition to reduce it's size and merge it with the sdcard partition. Depends on the partition table. But if it's not possible I think we could also split the system partition and make a sd-ext there instead. But of course that's very dangerous and is not recommended on average users.

Though, also a little surprised. Weren't HTC's flagship phones last year unified? That seems a retrograde step.

Wild guess is 2GB.
2GB data partition
12mb devlog
17mb kernel
17mb recovery
120mb cache
rest is system partition

On my one x i had around 11 usable, and i still have 2 gb free. so if i get the one , ill have around 17 gb of free space holy moly .. what can i do with so much free space, can i rent it out?

give it to me I need more extra space.

That's awful. Why did they go back from the awesome unified space in the HOX+. Thats was so great. If you had free space you could install apps. If the One really has an apps partition again, I'm going to have to move apps to sd-card again the whole time
Why did they make a step backwards?

[Q] Memory Shown Less

Hello,
The RAM shown in my Nexus6 is
Code:
Total: 2970MB
Available 1332MB (45%)
Java Heap: 256MB
The Total RAM 2970MB is shown in the apps CPU-Z and Droid Info. Why the value is lesser than 3GB (3072MB) ? There should be a technical reason for that. Please let me know. Thanks.

Yep, the difference is allocated to a bunch of other hardware blocks, like the MODEM.

okay, I also have learned from the internet that the difference is held by the GPU, which the OS is not aware of. So the Total: 2970MB shows the available memory and not the installed memory, Correct ?

Yes. Boot to bootloader and it will will tell you what brand and size ram and memory is installed in device.

Also the storage space shows 54.6GB instead of 64GB. Is it because of the reserved space allocated, when the filesystem is formatted to ext4 ?

But it takes almost 10GB of space, which is huge. I think it is good that I have brought a 64GB version.

os and firmware + extra for future updates takes up the first 10 giving you 54. Available is your userdata. Anything less that 54 is what you put on it.

okay, When I brought this phone the Available Storage was 51GB, without adding any data by me. So I think something else has taken space from the 54GB (54 - 51 = 3GB).
Then I added some music files and the Available Storage is 49.88GB now.

But it takes almost 10GB of space, which is huge. I think it is good that I have brought a 64GB version.

Not 10 GB, no. The difference is less.
In software, 64 GB is 64x1024 Bytes x 1024 KB x 1024 MB.
In hardware, 64 GB is 64x1000 x 1000 x 1000.
Because there is now a difference in what hardware manufacturers call a GB, they tried to rename the true software GB to be GiB instead (though generally I refuse to do this).
So to work out how many GB of software data you can get in a 64 GB hardware disk, use the maths below.
64 x 1000 x 1000 x 1000, / 1024 /1024 /1024 = 59.6 GB
So a 64 GB anything is only really 59 GB.
Then as mentioned, that is partitioned into /system, /cache, /data etc

Okay, So is 'Total Internal Storage: 54.64 GB' the size of the /system partition or /data partition ?
Thanks.

/data AKA userdata. This is where your apps go, where your settings are stored and where your sdcard is.

So that 3 GB (54.64GB - 51GB) is used by the apps, I guess. So that is the reason why it was showing 'Available Storage: 51GB' at the beginning.
Thanks.

When you get the phone new, when you boot it, some system settings will be stored in data. Also some things related to Android Run time.

If the remaining space (64GB - 54.6GB) is used by the OS and firmware, then what does the Available Storage mean ?
The Available Storage shows 49.88GB (91%). I mean there is one more difference: 54.6GB - 49.88GB. Please clarify. Thanks.

54.6 - 49.9 = 4.7
4.7 / 54.6 = 0.0861
0.0861 = 8.61%
8.61% rounded to the nearest percent = 9%
100 - 9 = 91.
Does that clarify it for you?
