Hi, I'm having this issue where the CWM nand backup of the whole system fails. I upgraded to the latest CM10 version, and still it crashes.
It goes as:
CWM-Based Recovery v6.0.1.2
SD Card space free: 26140MB
Backing up boot image...
Backing up recovery image...
Backing up system...
Freeing space... [stays rather long here]
Backing up data...
Error while making a backup image of /data!
So I dumped the log to check, and I found this:
Error while making a backup image of /data!
I:Can't partition unsafe device: /dev/block/mmcblk1p1
I:Can't format unknown volume: /external_sd

Do you have any idea of what's going on? Thank you!

Hmm, well the /external_sd dir doesn't exist on CM10 (or any JB ROMs for that matter). Have you tried backup to internal sd card?

Good point there. Yeah, I tried to backup to internal, having the same failure. But you´re right, /external_sd isn't supposed to be there anymore. It's just a file link, so I reckon I can remove it. Will try. But what about the previous problem? I don't know what is it referred to.

i will keep it simple ..Custom recovery is unable to take a nandroid backup if i have a2sd on ext4 partition that same run nandroid-mobile.sh via adb...please fix it or tell me how to.. i m new to android but m good with C and Linux
i had same as your problem , every time when i try to include .android and ext files with my backup it gives me error message , but after i installed a new rom everything went fine!!
For me mounting of ext in recovery helped as well.

Well this thing happens with BOTH megatron and void roms...when i boot into custom recovery /cache is the only one mounted and i tried unmounting it before trying a nand+ext+.android_secure backup...doesn't work my sd card is like 3 gb free and ext4 a2sd has only 130Mb of apps in it..
Guys I had made a simple nandroid backup after rootingand installing custom recovr and before installing void. Now if I restore the nandroid backup, will I still have the custom recovery or not?

even nadroid back up with ext ends: run nandroid-mobile.sh via adb
any solution??
Boot in recovery mode.
Connect phone to pc.
Mount ext partition via adb.(after that in Custom recovery mount menu you will found ext partition mounted)
Do nandroid

Same as me. I didn't do wipe of EXT after creating of ext-part and I had same symptoms. Backup all your data with Titanium Backup, backup data on SDcard, delete ext, create ext2 again, convert ext2 on one, that you want, do wipe of it. Than it should be working (I had).

ext2 is faster, because it haven't journal. But it on some I/O output error is not possible to recover it by itself. Ext3 have journal - is slower, but in case of problem will (can) repair itself. ext4 is better ext3.

At the time I made the recovery kernel sources were not out so I couldnt add ext3 & ext4 support to recovery. I'll try to update it as time allows.
mount -t ext4 /dev/block/mmcblk0p2 /sd-ext
be shure /se-ext exists

i know that.. but in ext4 i couldnt take a nandroid +ext backup because the ext4 partition could not be mounted. in ext2 and ext3 i managed to do nandroid backup +ext and mount the ext partition only through adb..
Hey guys.
I've read some threads about moving ext4 from one SD to another, but this isn't exactly what I need.
I am currently on MIUI XJ 1.8.12 XPart rom and I want to change to 1.8.12 A2SD+ and a bigger SD card.
Changing the rom isn't the problem, but backing up my ext4 partition from the old SD is!
I used the newest ubuntu live CD(11.04 I believe) to partition the new SD card to FAT32/ext4. Everything is fine.
The SD gets recognized as it should. FAT32 and EXT4 partition mount and I can access them.
But with my old SD it doesn't work.
If I plug it in, FAT32 and EXT4 partition get recognized. FAT32 partition is named "195" and EXT4 is "userdata".
When I try to click the EXT4 it just dissappears. In the media tab it is listed, but I can't access it because I am not the owner of it/I am missing permissions/rights to access it.
I partitioned it with CWM recovery, but meanwhile I changed my recovery to RMD 1.03 (I don't think that this matters though...).
Now my questions:
1. How can I access my EXT4 partition to backup its content?
2. If I can't access it because I can't change permissions... do I really need to copy it or will it be enough to restore my apps that I backed up under xpart with MIUI Backup?
3. Is it a problem to restore a app backup done under xpart-script with a a2sd+ rom?
Thank you for reading!
you can backup your ext partition in recovery. i think you can also just open a file explorer and copy the folder /sd-ext (i havent tried this, so im not sure if this will work)
Ok, I haven't tried to backup it with recovery.
Will it then be possible to flash a new rom (a2sd+ instead of xpart) and restore only the ext partition?
I want a clean install with a2sd+ but I don't want to loose settings and savegames.
Just a small "up" for my thread.
I backed up my sd-ext partition and I could wipe right now.
Will there be any problems with restoring the ext partition on a new rom?
What will happen if I just wipe sd-ext and restore MIUI Backup?
Will sd-ext will just be "rebuilded" from the MIUI Backup?

there will only be problems if your rom does not support either your a2sd or your current ext filesystem (which is to say, does it support ext4 or does it only support ext2 or ext3?)

i believe so (please dont take my word for it as i have not done this before. however, im pretty sure it will be "rebuilt" as you have it included in your backup)
Thank you again.
Its the MIUI rom from XJ for Desire Classic with XPART script. Your ext Partition gets converted to ext4 if you install this rom.
Will there be problems with using sd-ext content from XPART after update to A2SD+?
Maybe I'll bother the dev from this rom
I've got a weird problem. I successfully rooted my new HTC Flyer and installed CWM. When I rooted my new device I only had a very small sd card at hand which I replaced a few days later by a fast 32 GB sd card.
After the replacement I reinstalled CWM 4.0.1.4 but every time I try to do a nandroid backup nothing seems to happen. A progress bar is displayed but there doesn't seem to be any progress.
This is what CWM tells me:
Revolutionary CWM v4.0.1.4
SD Card space free: 25496MB
Backing up boot image...
Backing up recovery image...
Backing up system...
Backing up data...
No /sdcard/.android_secure found. Skipping backup of applications on external storage.
Backing up cache...
No sd-ext found. Skipping backup of sd-ext.
Generating md5 sum...
Backup complete! (obviously not!)
Using file expert I can see .android_secure in /sdcard (probably internal "sd card") but not in sdcard2 (probably my 32 Gb sd card). In /sdcard and /sdcard2 there's adirectory clockworkmod. The first one only contains a directory called download and a file .settings. The latter one contains a directory backup and under it directories for each backup attempt.
The question is: Can I trust these backups in case something is going wrong and I need to do a restore? Given the above error message I doubt that. So my next question is: What can I do to fix the problem?
Thanks in advance.
simulacrum
Yes you can trust the backup.
And what about the above error messages?
they just mean that you have no apps on the sd card. They always throw that error at me. It's fine.
I get the same thing when I do it on my thunderbolt. Go to your SD card under cwm/backup and you will find the backups. They should be named with the date you did it.

I have rooted my HTC Explorer and flashed it with Superuser Rom.
Now i want to flash my device with ics rom.
But it requires sd/ext partition.
I have created one worth 1.27 gb on my 8gb SD card with FAT32 partition.
Link2sd works fine with this sd/ext partition.
But when i try mounting sd/ext from recovery it diplays an error as
Error: Mounting Sd/ext
I have tried with all types of partitions (Ext 2/3/4)
But Ext 2/3/4 is not supported on my device (says Link2SD)
So i have to stick with FAT32
that 2nd partition i created with MiniTool works as a charm with Link2SD (everything works fine)

yeah for sense 4.0 you need to mount SD-ext partition from recovery.
I already tried formatting from recovery but it never worked out for me
factory reset should have done the same.

Yes. You can merge the ext partition using MiniTool ...
But why do you wanna do that ? Pico is short of internal memory and you will need sd-ext to increase your internal memory.
Hey guys, wondering if you could help me. I'm running Jelly Blast V-3.5, with Rafaels Kernel 2.6.35-7 on my S5380i. I've been trying to increase the internal storage on my device by partitioning my 32gb card in CWM with a 1gb ext. I've tried every solution I've found on this forum but I simply cannot get it to mount. Link2sd yields 'invalid argument' no matter where I point it, and when trying to format/mount the ext. in CWM it just says 'apps 2 sd partition not found'.
Here's a list of the things I've tried which have failed to solve this:
Partitioning in minitool, with various sizes and exts, and setting the partition as active.
Flashing conrod script, doesnt seem to be effective.
Script to mount sd-ext at boot, followed iamareebjamal's guide found here http://forum.xda-developers.com/showthread.php?t=1971689
S2E
Mount2SD
I'm completely at a loss, and with the internal storage of the S5380i being what it is, it would be great if anyone could offer me any advice.
Thanks!
do one thing , I'm recovery check if sd-ext is mounted
it used to happen to me that when I flashed new roms I had to mount sd-ext from mounts and storage
so mount it then reboot your phone
go to link2sd and create mount script as ext4
if problem persists , go in storage info of link2sd so see if the partition is mounted
if not you will have to enable auto mount at boot ( if option present in rom ) or mount using terminal emulator

Thanks for responding.
Attempted to mount in CWM but just receive an error. It's as if the partition isn't there at all. Re-partioned the card but still, no luck.
My rom doesn't have the auto mount at boot option, so it looks I'll have to mount with terminal emulator. Could you run me through the process, or point me towards a guide? Cheers
what error did you get in cwm while mounting ?
yry this line in terminal
mount -o rw /dev/block/
mmcblk0p2 /sd-ext
also is mount2sd file present in your /etc /init.d folder ?
Sent from my GT-S5670 using xda premium
The error in CWM when attempting to mount is: 'Error mounting /sd-ext!'
'mount -o rw /dev/block/mmcblk0p2 /sd-ext' in Terminal Emulator yields the following line: 'Usage: mount [-r] [-w] [-o options] [-t type] device directory'
The mount2sd file is not currently present in my init.d folder as I restored my phone from a backup, though when it has been there, the error in CWM is still the same.
The only difference I have noticed is that when partitioning with MiniTool, Link2SD will say that the partition is not mounted, but when partitioning with CWM it will say that the partition is not found.

Did you format ext2 in the secind partition? Normally when you format with cwm, first partition is fat32 and the second partition is ext2. Try to format all available space to 1 partition and using cwm format the card to two part. May be partitioning before makes cwm recognize the wrong part and gives error.

Tried so many different ways/combinations of partitions now. Do you think it could be a kernel or rom issue?

Make sure you have backed up all your files in your sdcard they will all be deleted and recreated with two partition.
In CWM enter Advanced --> use Partition SD Card
Set your second (ext2/3/4) partition size then set swap to zero (0).

That unallocated space is your problem. Try to create an ext2/3 partion with mini tool. And if minitool gives error than you probably have a defected sd.
