E: unknown volume for path [/sd-ext] - G2 and Desire Z Q&A, Help & Troubleshooting

How do I fix this? I made an EXT partition of 256mb and I even tried formatting the sd card. Using a Patriot 16gb Micro sd Class 10 (don't know if that is relevant)
Also installed the recovery from fastboot. CWM 3.0.0.5

Where are you getting this error? Are you trying to set up Apps2ext? I think currently that only works on Enomther's ROM. If you aren't trying to run Apps2Ext, what is the EXT partition on your SD card for?

Apps2EXT is the same as Apps2SD right? If that's the case then yeah that's what I'm trying to do. I thought EXT Partition works with CM7? If not then guess I'll stop trying. I get that error in recovery when I wipe Dalvik Cache and when I try to mount SD-EXT Partition or when I try to format it.

Apps2sd and Apps2sd are two diffreant thing apps2sd stores apps on a FAT formatted sdcard (which is what Froyo uses as native apps2sd with apps that allow it and no widgets) , while apps2ext stores apps on a partition on your sd card formatted to EXT file system, which your phone mounts as part of its internal system so it will support widgets and apps that previously could only be supported on internal storage, so it considers it internal storage even though its on the sd card, so no they are not the same thing, right now the only rom that supports apps2ext is Enoms rom.

I think nowawdays Apps2SD is used to refer to the system built-in to Froyo for moving apps to the SD card (does not use ext file system or need special partitioning). This just works out of the box on any Vision ROM.
CM7 uses the ext4 filesystem for all of it's partitions, which is new (not sure if that's what you are talking about). Hadn't heard it supports Apps2Ext, but maybe?
If you aren't using Apps2Ext though, you should expect to see a warning about a missing sd-ext partition when doing that stuff in recovery, so you're okay.

Help with sd ext partitioning

Ok so this all started when I switched from Cyanogen to Fresh 3.2. I used Amon Ra's Recovery to wipe and because it said to so a full wipe I figured I had to wipe evey option on Amon Ra's Recovery including sd ext. When I did That I got and error that said "Error: run "wipe ext" from abd!". I read somewhere that that wasn't going to be a problem so I continued loading the rom and it booted fine. I ran into problems later on when I tried installing Backbreakers. I got an error in the notification bar that said "installation unsuccessful". I later got the same message when trying to install Angry Birds. I've learned from other threads that those games should work fine on Fresh's roms. I now have the newest Fresh rom and still have the same problem. Just recently I found out that I shouldn't have wiped sd ext partition if I didn't have one setup. Now, I never set one up myself, but maybe one was setup automatically through one of the roms I had used. Now I want to fix the problem with my Sd ext partition (I know I'm not using The term correctly because I no nothing about it) and find out what it does. If anyone could help me understand what an sd ext partition is and how to solve my problem I would be very thankful.

You can set it up in Ra recovery. It's very easy. Make sure you back up your sd card to your computer cuz partitioning will wipe it.
Download DarkTremor from HERE
Select Partition SD card from the recovery menu
The first option is for a swap file which we dont really need so set it to 0MB
The next is for your ext partition. 256MB should be plenty but if you've got a large SD card feel free to go higher.
After that's done, you can upgrade it from ext2 to ext3 which isnt necessary.
Boot up the phone or mount sd card from recovery and place the DarkTremor file you downloaded on your sd card and flash as you would a rom.
After the phone boots up you can open a Terminal Emulator and type:
su (then press enter)
You should see a # symbol. Now type:
a2sd cachesd
This will move dalvik cache to your sd card and free up even more memory. Just remember to wipe ext partition before flashing a new rom and I believe you'll need to flash the DarkTremor file again after you flash a new rom. Your ext partition will remain. Hope this helps. If you have any more questions most can be answered in the DarkTremor thread or feel free to PM me.
Wow thanks for the great info. I'm going to do this hopefully it will fix my problem. What is an sd partition for anyways or what does it do? I have the 6gb sd card that came with my evo goe much space should I put for my ext partition? Thanks for all of the help.

The ext partition is a physical memory area in your sd card which is formated the same as the internal memory of the phone. Not like the rest of the sdcard. The limits are set on the rest of the card so the stuff in the ext with it's sequential byte order won't be over-written by the pc-like low-high byte order of the rest. Stuff can be logically assigned to the ext partition by the OS. At startup a find is issued on the partition, if it's there then automatically Fresh's / tremor's ap2sd "program" puts portions of applications on the sdcard. You can manually augment what gets put into the ext partition by issuing commands. Aps2sd was important on devices with limited internal memory.

Forgot to mention, its recommended you use a class 4 SD card or faster. I'm not certain what the consequences are but when I ran a2sd on my G1 with a class 2, the phone would crash.

[Q] Can't make apps move to SD card

Heya,
Today I flashed a fresh Defrost 6.1a (Which is said to support A2SD+), Flashed Gapps. So far so good.
I took my 8GB SD card and partitioned it in Ubuntu using Gpareted. I set the FAT32 partition first, then a ext3 partition (512MB) second.
Ubuntu read both with accurate sizes.
I put the card back into the phone and looked "SD card & phone storage", it no said my SD card is only 6.89GB, but the Internal phone storage was still low.
I decided to check a little more with Titanium Backup, which surprisingly said that my ext3 partition is only 256MB and is half full (talking about a fresh ROM here).
Can someone point me to where I did wrong?
Maybe format using ext4?
Put the ext partition first?
Reflash ROM after partitioning?
TNX
I have never got A2SD working either. I think you need to install a script or something. Here is a post about A2SD. Also, Android 2.2+ supports moving apps to SD anyway.
If you want more space to install apps, you can install one of AlphaRev's HBoot templates which can increase the /data partition, that's if you have S-Off.
I couldn't be bothered farting around with A2SD and so I did that instead.

No, it will not make it work and will only increase your memory card's wear.

So you flashed the a2sd enabled ROM on the device which didn't have memory card prepared? I always thought such enterprises would end in a boot loop. Flash it again if this is the case.

erklat said:
How do you inspect if a2sd is working? Coz I think u r doing it wrong. Install Quick system info and check what it says under a2sd storage and if it slowly decreases when you install apps, which means it is working. You don't have to set default install location anywhere, the script does that for you.
What you are referring to here, is Froyo's built-in a2sd which requires the app to be optimized for app2sd, that's why only some of your apps seem to be on the SD card. Furthermore, it will transfer the apps to FAT32 partition, that you don't want for it to do since Android first loads apps which need to be loaded at startup, and afterwards it mounts the SD card, which will lead to some apps failing to start after boot.
a2sd tricks the phone into thinking that ext partition is it's internal memory. Froyo app2sd != a2sd script, don't confuse those two, they are not the same.

Removing EXT3 Question

I've got an EXT3 partition with stuff installed on it and I'd like to get rid of it. Is there an easy way to copy the files that are in it back to the main FAT32? Or will I need to wipe the entire card and reinstall all of the apps?
http://forum.xda-developers.com/showthread.php?t=882758
With the new OxygeN HBOOT their is no longer a need for ext3 (in fact its slower), So to remove it you will need to download something like Gparted to manage the partition tables on your sdcard.
Delete the ext3 partition and completely reformat the card to fat32
Then install the new Oxygen HBOOT,
Then wipe cache's /all,
Then install OxygeN.

You can use this app to do this:
https://market.android.com/details?id=com.a0soft.gphone.app2sd&feature=search_result
Your rom still thinks you have the option "move to sd", because this is according to the fat32 partition of your sd card. In application settings android can only choose between "internal storage" or "fat 32 (sd card)".

sd-ext full, cant install on internall memory

I have a problem, and i cant manage to solve him, so any help will be apriciated.
I installed Runnymede AIO V6.0.4.3 Special Edition Stable Version
Problem is that every new app that i install goes diractly to the sd-ext. The partition of sd ext is 512, but after installing ROM it size is down to about 80 mb. So after installing few apps sd ext is full and i get an error. Meanwhille i have about 125 mb free on internal storage!
I tried su
a2sd remove, but it tells a2sd not found!
I`m really lost, tried everything for couple of days, so if anyone can help me, please do so...
This ROM requires 1 to 1.5GB ext4.
You might need to extend the sd-ext partition.
The easiest would be to backup your phone, repartition through recovery and reinstall the ROM.
I've been using this ROM for quite some time now and everything works perfectly with a 1GB ext partition.
But the rom is allready installed on sd ext and every other app that i installed later is also on sd ext. But now my sd ext is full, so i want to set as my default location internal memory, but i dont know how to do that... Does anyone have idea?

Sd Ext is "internal memory" - the a2sd etc scripts essentially fool the phone into thinking the sd Ext is part of the internal storage. Therefore increases the data storage for your user apps and is where they will install. This is why you have plenty of internal phone storage, but isn't anything to worry about.
Your actual problem using this Rom is that in common with other later sense Roms, parts of the Rom are also installed to the Sd Ext. This is why the sd Ext size needs to be bigger than 512MB, its filling up because its got parts of Rom plus all your user apps on it.
Sure the Rom thread will recommend what size is, needed. So do a nandroid (include sd Ext if AmonRa recovery), copy sd card contents to pc as backup, repartition using Gparted, copy sd backup back to card, nandroid restore.

You should try ad2sdx in order to increase the number of installed apps.

Can you explain it little bit to me? I`m not sure how this works.
Do you mean how the script works or what do you have to do to get the script working?

Do a backup (titanium, so that you can copy the backupfiles into your harddrive), and repartition the SD card. 1,5 to 2 Gb should be more than enough. Your problem is the same one I had with MIUI-XJ. Like people have said over, the problem is too little space on the partition. If you want to keep your messages and whatever else, there are apps to backup them as well. So... Yeah, 1,5-2GB of ext4 partition, than rewind.
But my sd card is already partitioned. How can i erase sd-ext, so i can partition it again?
Personaly if it was me id boot into recovery then do a backup then wipe/factory reset, wipe dalvik+cache and partition sdcard again (1gb) atleast, flash rom (install) restore backup. But thats just me

[Q] ROM can't find partition on SD card

I have a little problem with my WFS. I partitioned the SD card to use Int2Ext4, but the ROM keeps saying that no SD card is present, even if it does use the EXT partition. I can mount the card in CWM, I can see it's content there.
I'm using the ROM from OWL Project (this thread), the last version of it.
I would post there, but I don't have the post count yet.
Any advice? I'm currently repartitioning my SD card and try again. I reflashed the ROM a couple of times, fixed permissions as well from CWM.
Did you format your partition on the SD card with EXT4? INT2EXT4 only supports the ext4 file system, not ext2 or ext3. I use the INT2EXTV2 on myl WFS with the OWL ROM for a few weeks and it works without problems so far.

Yes, I used Ext4. I tried flashing Int2Ext, Int2Ext+, Int2ExtV2+ and Int2Ext4+ from CWM, but I was always stuck on bootloop. The only way I made it work was by extracting the script file from Int2Ext4+ and placing it in /system/etc/init.d of the ROM zip. Flashed it, it worked, but then I got this problem )
I'm thinking that maybe the FAT32 partition was not formatted correctly. So I'm doing that now.
I repartitioned the SD card and now it worked correctly. Weird is, I did the same thing as before, so I'm not really sure why it wasn't working in the first time.

i format the sdcard, cache, dalvik, etc then flash the script (data2sd or int2ext or int2ext+ or watever) then goto advanced then select partition sd card, select 512 MB and 0 MB for linux swap space. DONE, hope solves it for you
I have too WFS with OWL project and i dont have any problem with this
Go to recovery menu and here create partition (befor it backup sd card)
Then go to mount and storage menu > mount usb storage >connect usb cable > give cronomod on sd
Then go to install zip from sd card and instal cronomod INT2EXT+
And have more memory
After instal cronomod dont stres android start is first longer but only first then normal speed
Thanks for the answers. I did say I fixed it already by repartitioning the card. Probably I didn't format it right.
