Corrupter internal memory

Hi friends,
As you may know the build 2 of CM9 from our lord Arco sometimes mount the internal memory instead of the sdcard when the usb cable is connected.
Well, my problem is that I was formating it thinking it was my sdcard... the problem is that I have removed the cable in the middle of the format process. Now I'm not able to mount this partition.
How can I fix this issue?

As a basic solution:
A:
Can you still use CWM?
B:
Can you still boot into download mode and flash stock ROM? If yes, do so, flash CWM using ODIN and then flash CM9 again. (If no....... ask other members and see if they can help.)

As already mentioned:
1. Do all the backups you can make of your files.
2. Flash ClockWorkMod Recovery if you have not only done so(I guess you did )
3. Open ClockWorkMod Recovery:
I am not sure whether the memory swap in CM9 effects the management of the memory in CWM, but this is how it normally defined:
internal SD: mounts and storage-> format/sdcard ->confirm
external SD: mounts and storage-> format/emmc -> confirm
But I guess it does not make a difference for you, because you want to format both "sd cards" anyway.

Formatting /sdcard...
Error mounting /sdcard!
Skipping format...
Done.
/emmc works!

CWM mounts and storage question

I was changing the "mount /system, /cache, /data" options for something then realized I forgot what the original order of the "mount or unmount" should be. Currently it is:
-mount /system
-unmount /cache
-mount /data
-mount USB storage (at the bottom)
I'm asking because when I go to settings->storage I get the "Unfortunately, settings have stopped" error. I've searched other threads and found one exactly like this from a few months ago but unfortunately there were no replies. Does anyone know what these values should be by default? Its found by booting into CWM recovery and selecting mounts and storage. Thanks.

Combining internal and external sdcards as one storage unit? Android LVM?

Basically what im getting at is would it be possible to combine both storage units to where the os can mount them as one? In traditional Linux I would use LVM2.

Anybody? You think something like this would've been done already but I haven't found any directions on Google just a project page.

dude, desktop computers require an entire card in order to do this kind of stuff, it's called raid, and android isn't programmed to support it

That is incorrect. Try looking into what an LVM actually is before attempting to answer. RAID is something completely different.
Edit: not trying to be a **** but your post had a condescending tone to it.

schnowdapowda is correct, LVM would be able to do this just fine if Android supported it, but as far as I can tell the Android system doesn't have the kernel modules or systems in place sadly. Otherwise it'd be no problem making a physical volume from the two SD partitions, then a volume group and logical volumes.
One down side is you would run into system overhead while the slower SD card is keeping LVM from writing to faster on-board "SD card" partition space.
I just run the following at boot time, and it swaps the internal and external cards... Note this is with the Perseus kernel.
Code:
busybox mount -o remount,rw /
busybox mount -t exfat -o umask=0000 /dev/block/vold/179:49 /mnt/sdcard
if busybox mount | busybox grep vold/179:49; then
busybox mount -o bind /data/media /mnt/extSdCard
fi
I saw this on a website and it works perfectly, just need to verify your dev/block/vold/NNN:NN mount point and make this change after the SDCard is initialized.

How well does this work for you? And do you do this at every boot or only when you want to swap? Also when running apps after you swap the two and all of your other apps are already installed on internal then you swap the two, can you still just open the app drawer click and run? Or do they no longer run after the switch.
Also after the switch how does that all work when going into recovery and wiping directory's/folders etc and flashing ROM's what will it wipe since the directories are switched?

What is the benefit of swapping?

Sorry i had forgotten about this thread. This shouldn't effect app storage. Only SD storage and the mock SD storage partition on your internal memory. I believe it might screw up any apps you have installed on your external unless there is some mechanism that changes where the system thinks they're installed. And this wouldn't effect recovery as you cant run that script till startup.

Being able to save stuff automatically to your external without in app configuration.
Anyway.. this isn't what I'm really looking for. As far as I'd be concerned.. the system overhead wouldn't be an issue as I would gladly take a slowdown in read and writes to my storage for the convenience of having it accesible like that. I guess its just a matter of some genius dev compiling LVM into their kernel.

Big problems! Need help!

I have a big problem I cannot wipe data properly it say some errors like cannot mount .sdcard/.andorid secure and some E:format_volume: make_extf4fs dev/bloc/mmcblk0p2 and i cannot mount sdcard or mount usb storage before this happen I was playing a game in my phone and then normal using it kept it in my pocket for something like 5 mins then took out and found out it was switched off I turn it on but it wasnt booting(was Stuck at cm7 bootanimation). I did a factory reset it got booted but with problems as metioned before. What to do? Im using Outdated cm7 version of ItachiSama. Need help!

I'm afraid that you've to format your sdcard. Do backup of both partitions, do format and let us know if it helped.

Okkay but whats second partition. I have already kept a backup of the sdcard but whats the other partition?
EDIT: Can i format sdcard using cwm?

Oh sh.t when i press format sdcard on cwm it says Error mounting sdcard! Skip formatting sdcard Done! Now what I do

Never mind I fixed it but had to flash another ROM to fix bootloops. Thanks Maclaw and welcome back

Mount & format

Should I mount system In order to format system in cmw? And what if I just formatted system without mounting?

You shouldn't need to do it manually, it should mount it for you.

I know that if I mount system, it allows me to access system files and edit them but what about mount data?

/data doesn't usually get mounted on recovery boot. Most update scripts contain a line about mounting each partition that it needs to modify. You won't normally need to mount anything manually if you are simply using the "wipe" or "format" commands built into the recovery.

What if I just format data and cache in cwm via updater-script without mounting said partitions after the format command? Would it cause any problems? I just want to automate everything in the zip file and I'm only flashing system partition.

You need to mount system so you can do whatever you want with it

Yup, that's what I do.
1. Format system, cache, and data
2. Mount system
3. Extract system package
Never had problems with this order. What I want to confirm is if there is a need to mount cache and data after the format command even though the rom package is only for the system partition?

Just unmount system after everything

And i think that mounting system means mounting everything else because i never saw in a script mount /data nor /cache

No, it's different! The mount system in updater-script refers to the partition where /system is located. Cache and data partitions are separate from the system partition. So, if you want to flash something to data partition (e.g., apps, etc.) you have to mount it aside from that of the system partition.
