[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] Disabling lagfix, restoring hung up

I am in the process of disabling speedmod lagfix in order to flash Fasty 2.4. Nandroid backup is complete. It then switched to new configuration with the following:
Backup completed
Backup completed, recreating file system
Unmounting
Switching to new config
Creating /data
Creating /dbdata
Creating /cache
Mounting test
Unmounting again
Restoring data
Checking MD5 sums...
Restoring data...
net.bitbased.mwallpaper.zip
It has been hanging on the last line for over 15 minutes. I don't remember this being an issue when I enabled lagfix. Any ideas what I can do?

Decided to take action into my own hands and rebooted. Phone started up with stock Froyo. Transferred Fasty from my computer to phone and flashed it. Took less than 10 minutes to be up and running. What a relief! Proceeding with restoring all my apps and fine tuning Fasty. Looking forward to great things.

[help] Stucked while restoring Nandroid Backup...need some advice :(

Good Morning, my dear XDA com
Just started the common procedure, that we all know: restoring a nandroid backup!
Now I got stucked within the restoring process in the part "restoring system"...to become more precice, this is what I see:
--wiping data...
Formatting /data...
Formatting /cache...
Formatting /sd-ext...
Formatting /sdcard/.android_secure...
Error mounting /sdcard/.android_secure!
skipping format...
Data wipe complete...
E:can´t mount /sdcard
checking MD5 sum...
Erasing boot before restore...
Restoring boot image...
Restoring system...
Click to expand...
Click to collapse
The last line is what I see for a long time now. It´s kind of becoming a funny horror show to me atm, because I really don´t know what to do now. Its not that a good idea to pull the battery, is it?!
Need help guys...

Gud to wipe off data n retry

EDIT:
Seems like it´s working now, Battery Pull wasn´t a problem...beside the fact that CWM switched from TouchVersion to Blue Version to RedPill Version (?!).
But the note seems to restore my backup...
Long story short: Battery Pull seems not to harm the device when stucked at "restoring system"!
Thank you, Dr. Ketan!

Nandroid Without Rebooting to Recovery

I was wondering if any of you have used onandroid to create nandroid backups. It allows you to do this through terminal emulator while the phone is still online, no reboot to recovery (offline) necessary.
I just tried it. Below is the terminal output. I'm not sure if it was truly successful, but an interesting concept. Anybody else has experience with this app?
Code:
$ export PATH=/data/local/bin:$PATH
$ su

I have no experience with the app, but looks to be a little lacking if it didn't back up the recovery or boot. Just my two cents looks promising though.

OK, I didn't stay on top of this one at first but with help from the app's author, got it working on the Revo.
Boot and recovery weren't detected but now are after flashing the file for the Revo here. It adds the proper partition info for onandroid.
The second issue was an old busybox version causing a free space detection error. I used Stericson's Busybox Installer.

TWRP Error: 255

Property on my Galaxy Tab S2 MM TWRP 3.0.0. Installed. Have already made several backups, without problems.
For no apparent reason, backup creation is now aborted.
Have tried to write to the ext.Sd card and a USB stick
Have TWRP reinstalled. Without success. Times an older backup made and tried to save it again. Same error message.
Have determined that if I in the partitions selection "system" clicks error appears. For all other partitions not. Have the system partition reformatted, but nothing. Have deinstall ANTPlusTest.
If I check in the system-img check box instead of system does the backup
Does anyone have an idea what else I could make to fix the error? Also, I would be interested in what is the difference between system and system img. Is not system included in Sytem-Img? Then I would backup the system-img in the future.

It seems you may have a corrupted system partition and it fails to backup the ANTPlusTest.
System Image backup succeeds because it makes a raw copy of the entire partition, byte for byte.
Regular backup only backs up the files and folders.

That does not sound good. I had the partition already on ext4 formatted. Apparently unsuccessful. What can I do to repair the partition? I had formatted low level for hard disks. But Android?

Have you tried formatting with twrp using the advanced wipe options then flash the stock firmware or simply just delete that file?
Also something else to try. I remember someone else had the same issue, try backing up to different media. If your backing up to sdcard try internal or another sdcard or otg.

I've been here for a week on holiday and will deal with the problem afterwards.
I have formatted with TWRP ext4 and deleted the file. Wipe I had made and as medium int and ext SD card and also a USB stick. All without success.

I did with twrp wipe Dalvik / Art Cache; System; Data; Internal Storage; Cache and repair File System from System, Data and Cache.
Then I played back the last working backup. Now the error is fixed.
