CWM 2.x cannot mount ext4 partitions, gingerbread uses ext4 for /system, thus cwm 2.x cannot mount /system on gingerbread builds.
upgrade to cwm 3.x will solve your problems although at the moment it will introduce a whole lot more

Many thanks for this. Can you recommend an alternative backup AP?

I get that too. I have no trackpad at all so I use Rom manager and get that error. Also I've emailed you koush just wondering if its possible to add alternate confirm button for recovery. Power or many or something. I need to buy replacement trackpad otherwise lol.
I get the same issue. I tried ext2 3 and 4.
Can't wipe ext so it makes the recovery not very useful as I use a2sd.

I had this problem when using an EXT4 partition, fine with EXT3. I would try formatting your EXT to 3 and try again.

I am using the latest and no previous desire compatible recovery has worked for me. I will try formatting via Linux and try again
Currently got ext4 but had ext3 previously to no avail either

Clockwork Recovery 2.0.0.5 messes up root/recovery?

This is really odd, i just updated Clockwork Recovery to 2.0.0.5, i then tried to flash to behnam's cyanongen mod 5.0.8-test7. I used Clockwork to download the rom + googleapps..ok good so far, once the download was complete i was offered to backup the existing rom and or wipe data...i chose simply to wipe. The phone then asked me to confirm the reboot, which i did, and it rebooted the phone but now brings up the black phone with a red triangle. If i press vol up + power i access the recovery menu but haven't attempted a flash because i don't know why i now don't have a properly functioning recovery? I seem to still have root access from within my currently installed rom too :S
Help lol?
I had exactly the same thing with the cyanogen rom and rom manager. If you go ahead and press volume up and power while in the red triangle screen, the recovery will carry on and work as normal. I've done it a few times now.

Hmmmm interesting...so re-applying the recovery update.zip will just fix it? Wonder what changed in clockwork to make this happen?

Correct, I'm not sure why it happens randomly, that is how you'd access the recovery image, the image is the update.zip on your SD card. So apply that and you're there
i'm using the latest recovery and i can't mount the sd card anymore with /moun sdcard it gives error /dev/block/mmcbl0 can't be mounted,
never the less when i start amonra recovery batch and then go back to connect with adb shell to the still running clockwork recovery it works to mount the sd card strange behaviour
excuse me for this noob question... but what is this Clockwork Recovery?

Do a search for it on this forum, or try searching rom manager in here. There are at least 4-5 threads on it. One of which is very big! Try searching for 'fake flash'

this is not an issue, it is a feature of the new clockwork
i have spoken to Koush and what this means is that you are not using Apps2sd so there is nothing to be backed up.
the error should therefore be ignored as it is not a problem
Erm, this sounds like a bug. Can you join IRC:
http://webchat.freenode.net/?channels=koush
Ask for me, I'll be available.
I'm using apps2sd so the ext partition is there and schould be backed up!
i reverted to 1.8.9.2 (i think) and i backs up my ext partition just fine !
i'll join irc later !
Thanks to Koush for the assistance, top man.
Seems that some how the 'command' directory and 'update.zip' were missing from my /cache/ :s
koush, really nice support, fixed the sd-ext not mounting and not backing up in nandriod bug, and the mount sdcard bug within an hour over irc perfect!
could you post the solution koush gave?
just update to the latest recovery image (2.0.1.0)
mine's only offering 2.0.0.9
i talked to koush as well, nice fellow!
scroll down in Rom manager to older images, there you ll find 2.0.1.0

Unfortunately still not working for me on the latest Recovery (2.0.1.0)
Tried to backup my sd-ext (since that's where my A2SD apps are) and got:
Code:
E:Can't mount /dev/block/mmcblk0p2
(Invalid argument)
Could not mount sd-ext, sd-ext backup may not be supported on this device. Skipping backup of sd-ext.
I think my partition is ext4 if that makes a difference.

[Q] ClockworkMod Recovery can't backup SD-EXT

Suddenly my ClockworkMod recovery started to fail on acessing sd-ext.
My SD-EXT is an EXT4 partition, and I have done severall ROM backups before.
Now it just can't access SD-EXT. If I try to backup the ROM it returns the error:
E:Can't mount /dev/block/mmcblk0p2
(File exists)
I'm using version 2.5.0.1 of ClockworkMod Recovery but I also tried many older versions and the error is the same. The partition is working perfectly from A2SD...
I googled a lot and found many people with an issue like this, but no answers. What can I do?
did the backup work before?
As far as I know, ClockworkMod works by 'live patching' the normal recovery. So it has to use the normal recovery's kernel... which I think don't supports ext4.
you have to flash recovery via unrevoked, only then youll get a possibility to mount/format/backup your ext
It might be the Ext4 but I'm almost sure that it was working after I switched from Ext3

I flashed clockworkmod from unrevoked for the first time, but Ive been using Rom manager's versions ever since with success.

I dont know why it does not support ext4 :s

The latest version of Clockwork suppports EXT3 and EXT4 perfectly.
Are you using ROM Manager? if not, I urge you to do so. In ROM Manager, check that Clockwork Recovery is at version 2.5.0.1. If not, update it.
I've been using ROM manager. Recovery version 2.5.0.1

same here, with ext3 all is working but not with ext4 =(
Is there an easy way to copy the contents of the sd-ext partition to the Pc? (So I can go back to ext3 without wiping everything)

Maybe a live linux could help you out. Just boot from the cd then plug your phone in, it should now detects all your partitions.

cant mount sd-ext
hi.. any solution found to clockworkmod not being able to
mount the sd-ext?
i am trying to flash an a2we rom and can not because every time i partition my sd to ext4 (folowing a fat32 partition) i get this message from cmw2.5.0.7/3.0.0.5:
"cant mount sd-ext! (files exists)"
ehwn i try to wipe to factory defaults.
any ideas?
Hi are you sure a2sd is zip aligned and set up properly. Download terminal emulator from the market and type su (enter) a2sd check (enter) it will tell you if its working. if a2sd is not configured properly you can type su (enter) a2sd zipalign (enter) a2sd cachesd (enter)

Hi if you download root explorer and longpress on your SD ex you should get the option to copy.do this and paste it into your SD card folder. connect to PC and copy your sd ex folder that you previously pasted.

Hi all!
The linux solution works great but forces me to several minutes of waiting and I am also forced to use a laptop.
In other words, when I have not my laptop handy I can't do the trick.
I've asked the developer (hi Vache!) who ported clockworkmod to my beloved Acer Liquid Metal but then I thought...
It is such a simple thing: just a copy.
So I'd like to prepare a bash script to copy all the needed files from the sd-ext to fat32 sd and vice-versa.
The data is normally in /data/sdext2 but I'd need to mount it "manually" if it's not mounted (e.g. new rom flash)...
Using:
mount /dev/block/mmcblk0p2 /data/sdext2
will do the trick or I could destroy anything? à_à
As soon as I finish the script I'll post it.
fat 32 file system cannot preserve the permissions of files. So you can't do a simple copy. You can therefore do two things, one do as the recovery does, with a dd if/of command. Second solution is to simply do a tar backup.
su
mkdir /sdext
mount -t ext4 /dev/block/mmcblk0p2 /sdext
busybox tar cvvf /sdcard/mybackup.tgz /sdext
To restore,
su
mkdir /sdext
mount -t ext4 /dev/block/mmcblk0p2 /sdext
cd /
busybox tar xvvf /sdcard/mybackup.tgz
You may need to run it from recovery. su may not be needed, and if it is, you may need to mount system for busybox and su

S-OFF for SD ext?

Hi, I have a rooted myTouch 3G Slide running a custom mod (similar to stock with some tweaks) with S-ON
I wanted to be able to install my apps on the SD card and increase my internal memory with a 2nd partition on my SD card
I know everything on how to make the partition and the swap partition, how to format the partitions, how big to make them etc. I just want to ask:
DO I NEED TO HAVE S-OFF TO BE ABLE TO DO IT?
i recently tired very hard to do it using the Rom Manager and Link2SD as well as some other techniques such as making the partitions myself and using A2SD script with the A2SDGUI application. With just using Link2SD, i got an error that saied it cannot allocate the memory when I tried to create the boot script and when I used the A2SD script, it said that my apps were being sent to the sd card but when i rebooted, all of the apps i linked to the SD were gone and i was not able to get them back.
I've tried looking around the forums and on google but i have not been able to find a definitive answer to my question. Does my device need S-OFF or will I be able to do this with S-ON?
Thank you in advance.
bumpity?
I believe you do
http://forum.xda-developers.com/showthread.php?t=893706
actually, you don't need S-OFF to move your apps to the ext partition on your sd card. I haven't used any of the apps on market/play store myself, i've always just run the DTApp2SD script. Let me know if you need the zip for that.
@morphuex: the link you provided is for custom MTD, it will allow you to resize your phone's inner storage to fit your need, which does require S-OFF.
Oh, thought that what he was asking, must of read it wrong. :silly:
I've tried to apply dtapps2sd-2.7.5.3-beta04 to my device running CM9 beta 3 (Jun 21 2012) version and got unbootable device. It started and got stuck at the white T-mobile screen before CM9 animation.
Maybe this was caused by having s2e installed on the device which was used to move data to sd-ext partition. So just be careful and make a prior backup just in case.
By the way, does anybody know why I get an error message like 'unable to mount /sd-ext partition. unsupported by your device' while i'm trying to make a nandriod backup using CWM recovery?

yes, it means you don't have an sd-ext. if you do it will mount it. it will say the same error on anything that does a backup.
you do not need s-off to move apps to a created sd-ext. when my mt3gs was my daily phone i used simple2ext to manage my sd-ext. worked fine. i was using cm7.2.

This is not quite right. I had /sd-ext partition already created when I tried to make a backup. I did move there data & some apps using s2e app.
The same situation I experience right now. The ext partition does exist, but CWM doesn't mount it in backup process - "can't mount /dev/block/mmcblksomething (file already exists)" error.
Initially I partitioned my sd card using CWM. I created just ext partition only, no swap.
I use an unofficial CM9 beta4 build, rom manager version 5.0.0.8, recovery version 2.5.0.7. Should I try to flash more recent experimental version 2.5.1.4?

yeah, i duplicated that error just now. i fired up my old mt3gs and flashed the cm9 beta4. it does give that error and won't mount my sd-ext.
i honestly haven't read enough about the cm9 for this phone to give an informed answer, sorry. i know that if i flash my backup cm7.2 everything is fine. the only difference on my phone was the rom change. I did all this on rom manager 5.0.0.8, cwm recovery 2.5.0.7.
Thank you everyone for your contributions. i will try the DT app2sd script right now and will keep you guys informed on whether or nor i was able to do it. thank you!
I got a problem. i am unable to partition my SD because the version of CWM for my phone cannot do it..(it doesnt have the option to do it)
i tried doing it from rom manager but i get an error when i try to do it, saying the signature couldnt be verified.

[Q] Boot structure

Hi, I am a total newbie and I rooted my phone (HTC Desire) and have obviously misread some instruction as I seem to have created and Sd-ext partition on the internal drive instead of the external.
I installed JB4.1.1 which is nice and I like it but whenever I try to use the camera I get a "Gallery closed" error. I'm wondering if these can be linked and if the sd-ext partition shouldn't be there? Perhaps the gallery is trying to save in the wrong place or something? I am clutching at straws to thi problem.
How can I safely remove this partition and reclaim it back if it shouldn't be there?
Sorry for being a complete tube!

How did u manage to make an ext partition on the internal?
Tell us everything you have done.
Sent from my HTC Desire using xda app-developers app
I think it is on the internal????
I went into recovery and created it?
Options I have are:-
mount /data
mount /sdcard
mount /system

I highly doubt you made the partition on your internal. That would be difficult if not impossible.
Im guessing you just incorrectly made the partition.
Are you s-off? If so download the 4ext recovery app from http://4ext.net/. Install the apk and choose Online Install | Upgrade
It will ask if your phone is the HTC Desire GSM. Say yes, unless your phone isnt. (then go to the right forum )
Then you will see a list of all the different versions. Click on the latest one, and then install. It will tell you if it flashed succesfully, and then you can exit the app. To confirm it installed: turn off the phone, then turn it back on using power button + volume down. Then in bootloader select recovery. 4ext should come up instead of cwm.
Once you successfully have 4ext recovery installed look at this guide to see how to properly make the ext partition. Use the 4ext method and start at step [4].
Finally after you have done that, i would recommend doing a full wipe (everything except sd card) and reflashing the rom.
Many thanks, I'll try this. Good to know I couldn't screw anything up
Malk
