This is probably a noob question but...
I just flashed virtuous fusion 1.0.6 and I wiped data and caches beforehand but did not format my sd card. I was reading posts in the developer section and I was getting the impression that I was supposed to wipe the card too.
Did I miss a crucial step in converting to ext4 here?
Everything is working beautifully so far, but how do I know I'm using ext4? I want to make sure I did everything correctly.

EXT4 is the nature of the ROM. It "works" in EXT4.
as far as the SDcard being formatted they do that for Application purposes. If you didn't wipe it, don't worry about it. I typically do not wipe everything off the SDcard. It will also keep from using up all the memory quickly.
I recently flashed the new 4EXT Mod of ClockworkMod Recovery. The 4EXT Recovery is based off of Koush's CWM Recovery but offers additional power options, one of which is the ability to show the file system format your partitions are formatted in. To my surprise my system was formatted in the Ext 4 format and my data and cache partitions were formatted in Ext 3. The new 4EXT Recovery offers the option to convert the format without deleting any of the data. Your ROM will stay intact after the conversion. I selected that option and changed my data and cache partitions to ext 4 to match my system, rebooted, and notice quite an improvement in speed and smoothness in my current CM7 Nightly. After looking into it further I found out that the SuperwipeG2 that many of us have been flashing is formatting our partitions in the Ext 3 format. The reason only my system was formatted in ext 4 is because I used ClockworkMod Recovery the last time I did a full wipe to first flash the Superwipe, and then I immediately formatted system again with ClockworkMod Recovery. If you've used SuperwipeG2 to do a wipe, more than likely your system, data, and cache partitions are now Ext 3. You might want to check with your ROM developer to see if your ROM will run on the Ext 4 format. If its a CM7 based ROM, it will.
You can find more information about the Ext 4 format here.
Tsubus has since modified SuperwipeG2 so that it now formats the partitions into ext 4 when you flash it. I've used it and it also includes the EFS wipe. You can find it here. As I said, if there is no reason to wipe right now the new 4EXT Recovery can convert your partitions if you choose if they are in currently Ext 3. At the very least you can see what format they're currently in with 4EXT. I highly recommend it. You can always flash back to CWM Recovery if and when you choose. The partitions will remain Ext 4 once you choose to convert.
UPDATE: Several users have reported that checking partition information with Terminal Emulator is not reliable.
i just caught this issue this morning as well, all my partitions are in ext3, going to convert today. thanks for this post and the links to the new superwipe! +1

Thanks for pointing this out. I have all of mine in ext3 right now and plan on converting to ext4 here in a minute.
if ive never used superwipe my partitions are still in EXT4?

Probably yes, but it wouldn't hurt to check. The new 4EXT Recovery will display your current partition status. Then you'll know for sure.

So could someone clarify my understanding of this? If we are currently using ext3 we have 2 options to move to ex4 and keep CWM:
1) keep CWM, use the new superwipe+ext4, flash cm7
2) switch to 4ext recovery, convert fs to ext4, go back to CWM recovery
Alternatively, I would consider switching to 4EXT recovery permanently, but I am a bit reluctant to ditch CWM just because I'm so used to it. Is it worth the switch?

ClockworkMod is using the Ext 4 format. Its just that currently there is no way to tell what format your partitions are formatted in with CWM. If you flash the SuperWipeG2+ext4 from tsubus with CWM and don't ever use the original Superwipe and don't restore a backup, you're all set and done. BUT, if you restore a backup created by CWM that was partitioned at the time you created the backup in Ext 3, you'll be back to Ext 3 again. IE you've got to scrap all your old backups....all of us do if we want to stay with Ext 4. So, if you're willing to do a full wipe with the new SuperWipeG2+ext4 and CWM, you're good to go.
edit: yes to your number two. You can convert your Ext 3 partitions to Ext 4 with the new 4EXT Recovery and then go back to CWM. As I said above, after you do this you need to get rid of the original Superwipe and not restore old backups made in the Ext 3 format.

I think I've just made the switch to 4EXT, it was very painless and I like the features of the recovery. Now I'm wondering, with the 4EXT recovery, do we still need the superwipeg2 zips (including the new, ext4 modified one)? Also, is there a thread with discussion about the SuperWipeG2+ext4.zip (i.e., where did you find the link to download it)?

Use the new Superwipe just like you did and when you needed the old one. Tsubus modified it to format the partitions in ext 4. You can find his thread in the Development section. Its the CM7 ILWT thread. He modified the Superwipe right befor he went away for the weekend. The original link is in the OP of that thread. Be sure and hit his "thanks" button.

Thanks very much for the info and links, Ed. I will make the switch and give you a proper 'thanks' later tonight.

typing the following in terminal
Code:
mount
will tell you what filesystem types like ext2 ext3 ext4 etc, so u dont really need the other recovery to check if you're using ext3.
Code:
/dev/block/mmcblk0p25 [B]on /system type ext4 [/B](ro,relatime,barrier=1,data=ordered)
/dev/block/mmcblk0p26 [B]on /data type ext4 [/B](rw,nosuid,nodev,noatime,barrier=1,data=ordered,noauto_da_alloc)
/dev/block/mmcblk0p27 [B]on /cache type ext4 [/B](rw,nosuid,nodev,noatime,barrier=1,data=ordered)
/dev/block/mmcblk0p28 [B]on /devlog type ext4 [/B](rw,nosuid,nodev,noatime,barrier=1,data=ordered)
Still, I never even noticed that it was formatted as ext3 until i saw your post. Used the new superwipe and a fresh cm7 nightly. Everything flies now! Thanks for noticing the issue
Just checked via terminal emulator and mine are all in EXT4. Never used Superwipe before so I guess that's why.

WARNING: Ptesmoke and Ditamae have reported that this method wasn't accurate for them. Results reported by terminal emulator didn't match the actual file system ext's when they booted into 4EXT Recovery. After converting they have both posted that they noticed an improvement in performance.
Strange... so I checked thru Terminal and all partitions were EXT4, but after flashing the 4EXT Recovery and booting into recovery I discovered that data and cache were in fact EXT3. Hmm... I'm converting now, at any rate. Thanks again, Ed.
Just to clarify...
So the original Superwipe changes our partitions to ext3, and the new Superwipe up above changes/keeps it at ext4.
If that is correct it seems like we should remove the other instances of the original Superwipe in the forum and switch everyone over to the new Superwipe. What does reformatting via CWM change the file system to?

Yes, the original Superwipe changes the partitions to Ext 3. I'm not sure if there are other ROMs out there doing the same thing. It depends on the scripting. Many ROMs are scripted to format the partitions first when you flash them. If users reading this thread take the information and post it to their ROM thread in the Development section of the forum that would help to get the news out to check to see if their partitions are formatted correctly.
Thanks OP! I used (my new friend) 4EXT Recovery and converted my data and cash partitions to ext4, got rid of my old SuperWipe and Dow loaded the new Superwipe.
CM7 does indeed seem smoother, and overall a bit faster.
Big thanks for the heads up!

Also noticed the "eccentricity" of my /data and /cache being ext3, conversion to /ext4 was painless and the phone does seem to be running more smoothly.
(Then again, I utterly love this recovery--so powerful, and yet so simple to use )
Aaaand interestingly, at least if ROM Manager is any guide, they've finally pulled the 5.0.0.x "Seppuku Builds" of CWM. Which is nice, but 4EXT has sold me
I have a question that maybe someone in this thread could answer. As I said previously, I flashed the 4EXT Recovery last night and changed my data and cache from ext3 to ext4. Afterward, I noticed that my internal memory usage had decreased by approximately 70Mbs. Is this a result of less fragmentation? I'm assuming it's just a benefit of the way fourth extended filesystem works. Can anyone confirm this? Thanks in advance.
Hi,
I recently made the jump to CM7.1 KANG Oct24th, with ClockworkMod 5.0.2.0. All seems to be working very well.
But then I tried to do a ClockworkMod backup, just like I've always done. It worked through all the partitions, until sd-ext. I then get the following error:
"Could not mount sd-ext. sd-ext backup may not be supported on this device. Skipping backup of sd-ext" followed by the usual "Generating md5 sum..."
On another forum there was a mention that this error is normal. Does everyone get this error?
I think I created the SDCard partitions using ClockworkMod, so I have a 1024MB Ext4. It is my understanding that Ext4 is supported. It must be, as (I think) I used Clockwork to create the partition. I'm not certain about that, as I was also experimenting with GParted to create partitions. But had the same problem.
I am using Link2SD to move some apps to sd-card, so without sd-ext partition, the backup is incomplete!
Anyone seen this? Any ideas what might be wrong? Or how to fix it?
Thanks.
clockworkmod doesn't support ext4 on the blade. ext3 works.
Hate to resurrect an old thread but is this still the case I'm having the same problem?
Looks like I'm going back to 4EXT. After installing the latest touch version of Clockwork mod I got this message also during backup. This is fine if you have no problems on your next ROM but what if you have problem with the next ROM you chose. Doing a full wipe will include reformating EXT4 partition. That means since Clockwork mod didn't backup your EXT4 you have no way of getting all the files you want from your previous ROM. I also thought of changing my partition from EXT4 to EXT3 but besides the fact that I will have to move all my files to my PC then transfer again I read somewhere that EXT3 is not as efficient as EXT4.

My version of CWM touch (the only one touch version there is afaik) does support ext4, both 6.0.1.1 stable and 6.0.1.2 experimental.
You can find it here: http://forum.xda-developers.com/showthread.php?t=1835279
You might have been using my older testing version which had a problem with some ext4 partitions (notably ext4 partitions with special attributes).

Sorry I didn't notice the device name. I'm using HTC Desire. My latest version of HTC Desire doesn't support EXT4 anyways. It's Off-Topic here. NVM. Thanks.
Hello,
I've installed ICS now without any problems, but after installing the data2sd script and then rebooting my phone gets stuck in the boot animation. Even though it's very beautifull eyecandy it really isn't doing much for me.
I did a full wipe! Clear data/factory reset, Clear dalvick cash, etc. Also Task 29 and used HD2 toolkit to create 250MB system partiton with 5MB cache
First I formatted my SD card (8GB class 10) with MiniTool Partition Wizard 7 completely as FAT32 then I partitioned it (with CWM recovery 4.0.0.0) to 2048MB EXT3 with 256MB Swap, formatted that partition again in MiniTool to EXT3
Then I flashed the ROM (NexusHD2-IceCreamSandwich Beta6) to my device without any problem. Booted ICS, rebooted into recovery and flashed Data2SD installer wich didn't give any errors either.
Booted again and now it's stuck in bootscreen, I've waited for at least 45 to 60 minutes before removing the battery and try everything again all over, but with an EXT4 partition just like Yank555 did.
I followed the instructions from this post without flashing APP2SD Killer first since that causes the market to 'hang on app install'
I know there are people how got it to work so it must be something I did wrong! Can anyone give me some good advice?
BTW FYI, I did previously use TyphooN Gingerbread 2.3.3 CM7 A2SD with 1GB EXT partition without any problems...
Hi,
For me it seems you're doing it right...
Your ext4 partition IS a primary partition ? I suppose yes, since CWM will do it that way when you use it to partition your SD card.
Just to be sure, you did reformat the ext3 partion to ext3, or the swap ? I don't know how DATA2SD will react to finding 2 "sd-ext" partitons (more than one ext2/3/4 partiton), never tried that before... If you don't intend to use any swap, you'd rather leave that one out in CWM (choose 0Mb)...
JP.
PS: If you want to use swap (hard swap on a swap partition) I can explain to you how to do that. If you want to do it using a swapfile (once DATA2SD is up & running, you can have a look here).
Tanks for your reply. I don't have much time this weekend due to Christmas shopping and everything But I determent to get this to work! And I won't stop till I do. I'm using this ROM for every day and I just need more space. I found there are more people with the same issue as me, so when I get it to work I'll post my findings in the main development threat as well. But I'll make sure to give you all the credit that is due...
Fixed it! Did had to use sort of a "work-around" but it's working and it's all good! That's most important! If anyone else is looking for the solution for this problem, this is what I used and what works for me!
http://forum.xda-developers.com/showpost.php?p=20439320&postcount=2379
Please give thanks where they are due, that is to the original poster offcourse and not me!
The fixed work-around is App2SD rite? I think it will be good if we can get Data2SD working. I think the latter is faster.
I also read some managed to get Data2Ext working in Tytung ICS Beta7 already. See this http://forum.xda-developers.com/showthread.php?t=1403710

hey HD2 expert !! i have the same prob over here , installed data2sd after flashing the rom and stuckin at the boot screen ,,
-anyone find a solution !!!!!!
People have been having problems getting DarkTremor's A2SD script working on the latest builds of AOKP (ever since milestone 5).
Symptoms:
Reboot when attempting to install apps from Market or restore from TitaniumBackup
Cause:
The FAT32 partition is being mounted instead of the EXT2/3/4 partition. I don't know why.
Solution:
All of the main recoveries use the partitioning scheme 1:FAT, 2:EXT, 3:SWAP. Taking advantage of this, I patched DTA2SD script to mount the partitions based on the order. This seems to fix the problem and has worked for others.
Some have had trouble using this along with firerat mod. I suggest trying without firerat first.
I made this patch a few versions ago and posted about it on another forum:
rootzwiki.com/topic/17872-aokp-supersonic-may-24-build-37-404/page__st__560
You can see the feedback from people who have tried it already.

Good luck!
have had sucess with the a2sd from jm's cm9 port also assuming the same one as team dirts since they are pretty close lol (duh i know but thought i'd state it) anyways thanks for this too will give it a go next flash lol
