[Q] Can't convert /system to ext4?

As of last night I'm running CF Root 3 JVK on Gingerbread 2.3.3.
When I tried using the ext4 App to convert the file systems to ext4, it was successful for:
/dbdata
/data and
/cache
However for /system, it says:
Code:
Using: internal sdcard
Converting /system
- Backing up files ...
- Creating ext4 filesystem ...
- Restoring files ...
- Restore failed ! Not enough space ?
- Performing rollback ...
- Creating rfs filesystem ...
- Restoring files...
- Rollback success!
I cleared up some space on my phone and now I have 1.87GB available space on the sd card, and 13.26GB Available space on the USB storage.
and 1.75GB Available Space on System storage.
However I still can't convert /system to ext4.
Any ideas why this might be the case?

You need to free some space on /system to be able to successfully convert it to ext4. Apparently, ext4 needs some extra space for the conversion.
This is explained in the CF-Root main post, or in the CF-3.0 release information.

Okay thanks for that!
All the answers were in the original thread. I was just searching for the wrong terms.
I eventually downloaded Super Manager, activated its root mode and deleted the Aldiko eBook app from /system/app
That freed up enough space to convert /system to the ext4 filesystem!

[Q] app2ext on milestone

First of all, sorry for my bad english. I want to use an ext partition in my milestone, under [ROM] CyanogenMod 7.1.5 (Android 2.3.7) from kabaldan. I create the partition (primary, ext3) with EASEUS Partition Manager. After i download link2sd from market. When it starts, i see the popup of file system selection. I select ext3 from the list, and see the following error message: Mount script cannot be created. mount: mounting /dev/block/vold/179:2 on data/sdext2 failed: No such device. Can anyone help me? Thanks for the advices.

Try creating an ext4 partition and this app: https://market.android.com/details?...ult#?t=W251bGwsMSwxLDEsInJ1LmtyaWt1bi5zMmUiXQ..
Worked for me

Ok, works with ext4 in link2sd too. thx.

Link2SD is great - thank's for mentioning it - I finally managed to get cache2ext to work in MIUI

Check this post it very simple. http://forum.xda-developers.com/wiki/index.php?title=SD_card_partitioning

Why does every tutorial tell you to delete all partitions?
I just resized my FAT partition and created an ext4 in the unallocated space - works like a charm and usually doesn't even require backing up data first.

[HELP]Problem resizing partitions

I have a problem. I have try to resize the partition using nvflash. I have use guide from modaco and also the preconfigured files. The problem is that /system is always at ~360mb (stock size). All other partitions are resized propertly.
Any help?

I'm facing the same problem. I think I know what the problem is but I cannot solve it!
I currently have installed Stefan 28G ics rom (2nd edition) and my goal is to add about 100mb to the system partition, reducing internal /sdcard.
If I use fdisk command from adb shell I find out that the partion IS actually resized, but the file system on it isn't!!
So: partition now is 650Mb, but file system on it is 550Mb!
That's because nvflash simply makes a dd of the system.img (which has the old partition size) to the partition so in my opinion there are two solutions:
a) open system.img in a linux environment, add some stuff to reach 650Mb on it and repack it with the new size
b) backup system data, formata the partition (which is already resized) to get 650Mb file system and then restore your system data
I think that all "resizing guide" doesn't talk about this second step because in that case the system.img has always the right size.
Any ideas?

I solved my problem!
As explained before I have just added some stuff to the system.img file and then resized the file system:
dd if=/dev/zero bs=4096 count=35328 >> system.img
e2fsck -f system.img
resize2fs system.img
PS: bs and count depend on the partition size that you have set before in the .cfg file
Then NVFlashing again solve the problem!

Backup your rom with cwm.
Format /system in cwm.
Restore your cwm backup.

Nook Color CM10 emmc Data Partition Size

Loving the CM10 ROMs. Everything has been snappy on my nook since beta 2.
I thought I had the newer (revision 1.2+) nook partition layout (5gb data(apps)/1gb media). But now with CM10 I am getting an out of space error when trying to install new apps. I have moved all apps to my sd card and still get the error about not enough space. If I try and look at the partiton size it looks like it is maybe only 1gb now. Did installing a CM10 ROM change my partition size? Am I missing something else? Perhaps I am just wrong about my original partition sizes.
I searched some threads and the web and saw some discussion on my issue, particularly mention of a 'new CM10 partition layout', but this was confusing at best. It may not have even been nook related, but pertained to some phones.

You can tell by looking in settings and storage. It will tell you the size of your media storage. If you truly have the 1Gb /data, you might want to look at Dean Gibson's repartitioning thread. He has a 2gb/4gb version.
And no, there is no repartitioning that cm10 does. That was for a phone you saw.

Well, I think I do have the 5gb data/1gb media partition layout afterall.
In Setting->Apps->Downloaded it shows at the bottom 'Internal Storage, 753Mb used, 4.2Gb free'.
If I launch a terminal window:
$ df /data
/data Size=4G Used=643M Free=4G Blksize=4096
$ df /emmc
/emmc Size=1G Used=83M Free=942M Blksize=4096
$ df /mnt/sdcard
/mnt/sdcard Size=15G Used=10G Free=4G Blksize=8192
I guess the only app that is giving me the out of space is Titanium Backup. I can't get it to install from either the appstore or from .apk that I downloaded. Both methods start installing and then say 'out of space'. I have been installing and removing other apps along the way with no similar problem.
I did wipe cache/dalvik cache when installing ROM. I also tried CWM Fix Permissions. I also tried CWM Backup -> Wipe Data/Factory Reset -> Restore.
Anyone know why Titanium Backup won't install?

The only thing I can think of is some users are having read only problems on both SD card and /data, which is where apps get installed. Have you tried to install other apps since the TB install failed? A test you can try to see if you are one of the users with ro issues is to use a root file manager (there is one built into CM10 now) to create a test file somewhere on /data.

Hwo to resize system partition?

I picked up a free Nook HD+ from a friend. It came with, IIRC, CM10 and some old version of CWM6 installed.
I updated to TWRP 3.0.2 from here and installed the latest CM Ovation from that same site. Turns out it's Android 7.0. Open gApps worked okay, but the ROM had some issues (lots of crashes, Mail app didn't work, and there were no apps for Contacts or Calendar). Plus I didn't have root. So, I wiped everything - system, cache, data - and flashed CM12 from here. The OS works fine. The problem is, there isn't enough free space in /system to even flash the pico open gApps zip.
I booted into TWRP and got ADB working, and sure enough my /system partition is nearly 80% consumed. fdisk shows this:
Code:
/dev/block/mmcblk0p8 661.4M 521.1M 140.3M 79% /system
It seems like I should be able to use fdisk and resize2fs via ADB to resize my system partition, but I don't want to brick my device (obviously) - how do I resize /system so that I can install the minimal gApps to get Play working?

This is what I did:
