About data2loop to increase stability

My English is poor, so I only give the code, without more explanation.
code modiy from ownhere's data2ext
create 3rd ext4 partion for loopback device.
Please note '-o sync,commit=5',This will enhance the stability.
Code:
$BUSYBOX mknod /dev/loop0 b 7 0
$BUSYBOX losetup /dev/loop0 /dev/block/mmcblk3p3
$BUSYBOX mount -t ext4 -o sync,commit=5,barrier=1,nouser_xattr,errors=continue,noatime,nodiratime,nosuid,nodev /dev/loop0 /mnt/asec/extdata
you can turn off journal for speed：
Code:
/system/bin/tune2fs -O ^has_journal /dev/block/mmcblk3p3
Code:
busybox ls -lL /dev/loop*
brw------- 1 0 0 7, 0 Jan 9 19:17 /dev/loop0
brw------- 1 0 0 7, 1 Jan 9 19:17 /dev/loop1
brw------- 1 0 0 7, 2 Jan 9 19:17 /dev/loop2
brw------- 1 0 0 7, 3 Jan 9 19:17 /dev/loop3
brw------- 1 0 0 7, 4 Jan 9 19:17 /dev/loop4
brw------- 1 0 0 7, 5 Jan 9 19:17 /dev/loop5
brw------- 1 0 0 7, 6 Jan 9 19:17 /dev/loop6
brw------- 1 0 0 7, 7 Jan 9 19:17 /dev/loop7

Scoring won't be so high, but stability will increase a lot

Hi Chenglu, I've actually already tried to modify your original data2loop script to use ext4 and run it with a kernel with ext4 built in. It actually benchmarks great on first boot, somewhat better than the original ext2 data2loop version, but the tablet won't boot again, it crashes sometime during boot and I have to wipe data and restart.
Not sure if the sync,commit=5 options will make a difference - maybe I'll give that a try and see if it helps...
EDIT: No, it still pukes out on reboot, those options don't make a difference. I've attached my inandop.sh file here. If you diff this with yours, there are only a few changes, and I'm just not sure why it doesn't work. Any ideas?

Chenglu...
Thanks... this should help... but I am still very concerned with this approach..
Even though you are performing a sync you still can not guarantee that the data has been flushed out.. Flushing will depend on what other operations are in queue within the I/O sub system. In addition, right now you have a commit of every 5 seconds which honestly again leaves room for possible corruption. Again should help as this setting is meant for removable storage...
Lastly DO NOT turn off the Journal. yes it will speed up the file system BUT at a HUUGE risk of data loss in the event of unclean shutdown. This is your only fail safe that ensures filesystem consistency even across unclean shutdown.
Generally I agree with this approach for many situations but NOT your entire system partition or critical data partitions...
These devices are too portable with unreliable power sources (not the battery but the ability for it to reboot on its own and the ability for you to accidentally power it off)..
I for one am against this performance boost...

Fast internal storage and ext4 partion is the fundamental solution.
loopback device In some respects have an advantage.

I dont dispute the performance gain... but at a risk. Everyone should be aware of this and accept the risk... If you do then thats fine...
I guess I'm more conservative when it comes to my data.

good point, that was a mistake. I am now using a statically compiled version of mkfs.ext4 that seems to work. Mount doesn't need explicit ext4 support in busybox, should just work. And I think I'm using a version of fsck that supports ext4.
EDIT: Okay, I'm using mkfs.ext4 which I've tested from the command line and it is clearly making a real ext4 filesystem. Also using a version of es2fsck that ought to work with ext4. These are both from the Desire forums, but seem to be generic ARM binaries so they seem to run on our G Tablet.
Still same result - works on first boot, not thereafter.
Maybe I need to use a version of busybox that explicitly supports ext4? Trying that next.
BTW, I got the binaries I'm using from the data2ext.zip file here: http://forum.xda-developers.com/showthread.php?t=859419
Also - ownhere's script looks pretty badass. We should consider using something based on that.
EDIT2: I am using busybox, mkfs.ext4 and e2fsck from the Desire forums, so it should support ext4 fully. Nonetheless, the exact same screen flicker followed by screen shutting off occurs with this. Attached is my updated inandop.sh. This is just baffling.

I'm working on this as well...
Took a look at your script. It looks like you've put everything (including busybox) into /system/bin instead of /system/xbin? Your environment variable for busybox shows /system/bin...
Just wanted to confirm...

I'm unable to get the loop file to mount as ext4 with ADB after it fails...
I'm not sure if/why it actually mounted in the first place, but I'm thinking this is a kernel issue. Are you positive that your kernel supports ext4? Also, I'm thinking ext4 might need to be compiled into the kernel instead of a module.
I could be wrong, though....

Also check which mount binary you are using. Busybox has one, but there is also a "mount" sometimes linked to the "toolbox" binary in /system/bin.

Ok so I (sort of) got it working.
After getting a kernel that is known working with ext4, the system was able to mount the partition again. I was getting the vegan "loop", so I went in with ADB and saw that the partition was mounted but all of the files were gone.
I then booted into CW and mounted USB, and at the same time on my PC I extracted my /data/data folder from a recent clockwork backup and copied it to /sdcard. I then unmounted USB and mounted /system and /sdcard from CW. Then from ADB I copied the data folder over to /mnt/asec/extdata and fixed the perms. I created empty folders for app-private and anr because they were empty on my backup (other than a traces.txt file in anr).
After bouncing the tab it booted up, but some of my settings were blown away. No big deal. Quadrant crashes at the I/O test part, but it might be because I don't have an Internet connection. The wifi is broken with the kernel I'm using.
Let me know if you still can't get things mounted. I'll test this more tomorrow when I get a fixed kernel.
I'm going to start working on the alternate approach of adding a 3rd partition...

The kernel should support ext4, I built it myself with ext4 enabled in the config file. And yeah, I put the busybox executable in /system/bin so it wouldn't conflict with the one in /system/xbin that Vegan already has. I also dumped mkfs.ext4 in /system/bin.
What I realized is that busybox has a nasty habit of failing partially at doing things - I keep assuming that it's exactly like the stock Linux command line tools, and it's not always identical. I ended up tearing out the important stuff and running it as a standalone test script from the command line to see what was happening.
Mkfs.ext4 runs with no obvious issues (I see it creates a journal at the end, so I know it's creating an ext4 filesystem now).
But then I got an error:
Code:
mount: mounting /dev/loop0 on /mnt/asec/extdata failed: Invalid argument
followed by:
Code:
umount: can't umount /mnt/asec/extdata: Invalid argument
e2fsck 1.41.6 (30-May-2009)
ext2fs_check_if_mount: Can't check if filesystem is mounted due to missing mtab file while determining whether /data/ext4 is mounted.
/system/bin/e2fsck: Superblock invalid, trying backup blocks...
/system/bin/e2fsck: Bad magic number in super-block while trying to open /data/ext4
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
mount: mounting /dev/loop0 on /mnt/asec/extdata failed: Invalid argument
So mount failed to mount the file device that was created - that would seem to be a big issue. And then e2fsck failed to fsck it that one I'm baffled by.
I don't really understand how this "partially works" when it runs from inandop.sh but seems to fail entirely when I run it from the command line, but I sense that it "works once" because something it's getting sometimes written as ext4 sometimes as ext2/3 and that's leading obviously to corruption. Will figure more out later when I have time. I may just try adapting ownhere's script directly, he's obviously put a ton of thought into filesystem stuff and I'm not an expert in that area at all.

I was able to reboot 5 times and it kept the settings for me. I just couldnt test all apps because wifi was broken with the kernel I was using. I can test more today.
Are you sure that your ext4 format is completing? I got an mtab error when first trying to create the journal, so I just changed the script to format it with the -O ^has_journal option and it competed.
Vegan runs fine for me with latest busybox...

chenglu can you post the instructions on how to create a third partition and mount that instead of creating a loop file? I want to test that today.
Thanks,

In your instructions it looks like partition 3 isn't referenced, but instead you're formatting /data as ext4 instead of ext3? Or am I missing something???

Add the -O ^huge_file file option to your mkfs.ext4 when formating the partition. (it won't work with this feature since it requires special kernel option that brakes compatibility with existing modules)

I was able to reboot 5 times and it kept the settings for me. I just couldnt test all apps because wifi was broken with the kernel I was using. I can test more today.
Are you sure that your ext4 format is completing? I got an mtab error when first trying to create the journal, so I just changed the script to format it with the -O ^has_journal option and it competed.
Vegan runs fine for me with latest busybox...

Ubuntu

Currently trying to get this to work on my S2 and having issues.
My phone is running official KH3, CF-Rooted.

Boot Process research based on 2.2.3 Verizon WebDoctor

WIP research into HP Pre* boot process
Theoretical plan: port user-part to compatible droid - Pre3["rib"/"mantaray"]->XperiaRay["ST18i"]
Well, upstart scripts are complete... now for tracking dbus/luna services that are needed for the port to run..
Kernel configs:
linux-*/arch/arm/configs/rib_defconfig = pre3
linux-*/arch/arm/configs/semc_urushi_defconfig = xperia_ray
Device highlights:
sony: CONFIG_INPUT_APDS9702 (proximity filter)
sony: CONFIG_MDDI_NOVATEK_PANEL_SHARP_LS033T3LX01 (sharp display)
sony: CONFIG_MDDI_NOVATEK_PANEL_TMD_LT033MDV1000 (tmds controller)
sony: CONFIG_SND_MSM_MVS7x30_SOC (integrated audio)
sony: CONFIG_TI1271 (wifi)
sony: CONFIG_TOUCHSCREEN_CLEARPAD_I2C (synaptics clearpad)
palm: CONFIG_MT9P013 (5MP cmos)
palm: CONFIG_PMIC8058_UPL (qualcomm power management)
palm: CONFIG_SND_SOC_WM8994 (wolfson micro, 24bit 4-chan dac, 2-chan adc, 100dB SNR, Nice !)
palm: CONFIG_TOUCHSCREEN_CY8CTMA300 (cypress)
palm pre3 = "rib" or "mantaray"
WIFI: Pre3 -> Atheros 6K ar6000 driver = ar6k, non-upstream!, hardcoded in PmWifiService
Pre(1) -> Marvell sd8686 sd8xxx driver
Seems the biggest problem will be porting the WiFi manager, to make TexasInstruments 1271 look like an Atheros 6k series..
palm devices:
castle == Pre
pixie == Pixi ?
broadway == Pre2?
mantaray == Pre3
windsornot
topaz == TouchPad
opal
What do EVT1 EVT2 EVT3 / DVT1 DVT2 DVT3 mean ?
What are "opal" and "windsornot" devices ?

WIFI: Pre3 -> Atheros 6K ar6000 driver = ar6k, non-upstream!, hardcoded in PmWifiService
Pre(1) -> Marvell sd8686 sd8xxx driver
Seems the biggest problem will be porting the WiFi manager, to make TexasInstruments 1271 look like an Atheros 6k series..

ar6k is upstream in the staging branch since 2.6.37 according this :

Bactrack 5 - errors with ext2 and chroot

Hi everyone,
I'm a noob on this forum so i'll try to be as clear as possible.
I have some issues trying to install backtrack 5 ARM version on my Nexus 10.
Config :
Nexus 10
4.3
Kernel : 3.4.39-g446c9cf
Build number : JWR66Y
Terminal emulator
Busybox Free
What I did :
I rooted my Nexus 10 following this tutorial (checking custom recovery) :

I tried to install Backtrack 5 following this tutorial :

I have theese errors (by doing sh -x bt)
mount -t ext2 /dev/block/loop7 $mnt
>mount: Operation not supported on transport endpoint.
ifconfig etho
>eth0 : No such device
busybox chroot $mnt /bin/bash
>chroot: can't execute '/bin/bash' no such file or directory
losetup -d /dev/loop7
>losetup: /dev/loop7: No such device or address
I search on the forum but I can't find what is the real problem :
http://forum.xda-developers.com/showthread.php?t=2116059
--> cd /storage/emulated/legacy/bt5/ don't change anything.
I readed that ext2 and chroot not working could come from the 4.3 but I'm not sure about this information.
I readed that most of custom ROM handle this.
/bin/bash doesn't exist, but /system/bin/sh does exists but :
busybox chroot $mnt /system/bin/sh don't changes anything.
I'd be glad if you can help me understanding my problem

Possible script for better performance?

Coming from a galaxy s6 i remember when i used to find all types of scripts to make the phone perform better.
however these new gen phones make me believe that these scripts are obsolete, or are they?
below are my current scripts that ive used on almost all android devices.
id like to get input as to whether people see a difference (or any experience using these or similar scripts)
#flags all part' as non rotational and disables iostats (possible better throughput)
MTD=`ls -d /sys/block/*`;
for j in $MTD
# $LOOP $RAM
do
echo "0" > $j/queue/rotational;
echo "0" > $j/queue/iostats;
done
# Remount all partitions with noatime and others to possibly save cpu cycles requires bb
for k in $(busybox mount | grep relatime | cut -d " " -f3);
do
sync;
busybox mount -o remount,noatime,noauto_da_alloc,nosuid,nodev,nodiratime,barrier=0,data=writeback,nobh $k;
done;
#disable journaling possible throughput benefits
tune2fs -o journal_data_writeback /block/path/to/system
tune2fs -O ^has_journal /block/path/to/system
tune2fs -o journal_data_writeback /block/path/to/cache
tune2fs -O ^has_journal /block/path/to/cache
tune2fs -o journal_data_writeback /block/path/to/data
tune2fs -O ^has_journal /block/path/to/data
just thought id put them there for people to see if they have any benefits.

i think its subjective
i cant tell much difference
which is why if other people use it maybe they can tell the difference too
