I tried using MiniTool Partition Wizard to format my android sd card, I split the first half to be fat32 and the second half to be ext4, when I do that though the ext4 partition doesn't stay... I even tried twrp to partition it, to no avail it said it wasn't able to create the ext4 partition but the fat32 partition was made successfully.
**NOTE**
Apparently, you need a swap partition to be able to have ext4? Well, I created one and now everything works fine and dandy, before I didn't have one and it worked great...
You dont need swap for ext partitions.. there is no connection between them.
I dont know much about those tools but if you create partition through recovery.. first it makes ext2 partition later you need to upgrade it to ext4.

If I could post link I would, but since I cannot mostly because to the site I'm not a developer (stupid rules) and claims I cannot post anything truly helpful, so as an effect cannot post links to my recovery.
My recovery (ZenGarden 2.0.2.7-T) can create an ext2, ext3 and ext4 partition; the use chooses which format and because of Windows limitations you cannot have more then two partitions on an external drive.

Hey guys I have a problem with link2sd on my rooted HTC legend.I have made a ext2 partition of 500mb with easeus but when I start link2sd it asks me which file system I want want for the 2nd partition so I select ext2 but then I get an error ''mount script cannot be created not enough memory".also when I look in drive watch I see that 0mb/0mb is free of the 2nd partition.So my question is how to fix this.
I really need some help.........
maybe ext2 is not compatible with your system. try upgrading your ext2 partition to ext3 and see if that works!
link2sd?? isnt app2sd
Thanks for the response but when i format the ext2 partition to ext3 it doesn't seem to work either when i start up link2sd and select ext3 i get an error message"ext3 is not supported".If this won't work i'm willing to try data2ext but i don't know if it will work on my rom i currently have the b 0.7(stock htc froyo with root)rom.So that is another question.Do you guys know if it will work with my rom or maybe i need to mount my ext2 partition can you guys give me the command how to do this?
Hello,
I was wondering if someone could guide me with how to create a ext3 partition in Nexus S.
I tried creating a partition in sdcard using recovery and gparted. recovery keeps failing. says i am not using parted v1.8. etc. And gparted is rendering sdcard corrupted.
Any pointers?

Why would you want ext3 over the faster default ext4? As for the sd partitioning problem, I would leave it alone in gparted. It does the same thing for me, but shows up un-formatted. I wouldn't dare format it with a partition manager. I did that to a Droid Incredible once and soft bricked it. Took me days how to figure out how to re-partition the partitions. Just a word of advice.
Partition
Sorry,
I want to make a ext4 partition. We have paritions for boot, data, system, sdcard, misc etc.
I was trying to boot into debian in android with chroot. I was wondering if its possible to boot debian natively in Android. Right now, the display and frame buffer is not accessible when i chroot. I just need a partition, to put the debian image into. I dont know how to make this happen.
Any suggestions?
Thank you,
ANB
I did a backup of my chacha. Since I also used Link2SD I have the problem that the extra partition is not mounted correctly after restoring the backup.
Some Apps that are on the 2nd partition still work, but Link2SD refuses to create the link again ("Invalid argument"). Some manual guides tell me that I should add some mount script to /etc/init.d - but there is no init.d.
So any chance that I get my backup working again?
when you restore cwm backup it make the 2nd partition ext3 format and that maybe not support by the rom you use
if you are sure that your rom is support ext3 try to uninstall link2sd and install it again and choose ext3
Well, CWM will format the partition with ext4, but I changed it to ext3 since I was sure that I used ext3 before and this was also supported by this phone. So I don't think that this was the problem.
I also tried to reinstall Link2SD but no change.
try to use it as ext2

Thanks. I couldn't believe it because i used it as ext3 before. But now I changed it to Fat32 and it works. I had to do the restore of the sdext.tar manually because CMW always changed Fat32 to ext3 then. And when I formatted the partition with CMW before it was even ext4!
which one is better? ext2, ext3, ext4 or FAT32? and using what tools I should partition the sdcard?
I am using cm9.2.2
before that, I partition sdcard with Amonra Recovery with ext2 and use link2sd and have a problem, some times sdcard removed unexpected, when I reboot sdcard is not read, I pull out the sdcard and insert, and sdcard read normally. I reboot and sdcard not read again, I do this many time and finally can read sdcard. but it happens over and over again. I try to format the phone and install app, move app like unrooted phone, the sdcard work fine..when I try use ext2 with link2sd some times its happend again.,
help me..sorry for my bad english, I am Indonesian.
thank you before..
If you want to know what other people use to do this here I come:
How I make the ext partition:
Minitool partition wizard (windows)
Gparted (Linux)
Clockwork 6.0 (only for CM10+)
I didn't have any trouble with that programs, but be careful with the Clockwork because formats ALL the SD card, the ext and the fat partition, so make sure you do a backup of the SD.
Format of the second partition:
Always ext4
Link App
Link2sd is the best, other caused troubles over the time (reboots, not reading the sd, not reading the ext partition, etc)

before that, I've use ext4, but cm9 not support, I change the kernel and still not support ext4, when I use ext3 its work fine..,

I used ext4 in all CM from 7 to 11 and no trouble, but always formatting after every wipe with gparted or minitool, because Clockwork 5.0 seem to not format well the ext partition, so after every wipe you should reformat with those programs.
From my experience use ext3, it is good and compatible with everything, allmost

EXT4 has a tendency to corrupt

Ext4 works great.

I've been trying to partition my SD card, but all steps I take to try and diagnose why I am unable to partition the card is getting me nowhere.
Initially, I used gparted on my laptop to partition the SD card with a v-fat partition and a f2fs partition, both primary partitiond. This was when I found out that no matter what I do the second partition on the SD card, it doesn't seem like the format actually takes. Whatever tool I use complete the partitioning and formatting steps successfully by all appearances but it doesn't seem like the partition is ever actually formatted. What I mean by that is that no matter what the second partition is it never mounts. I get an invalid argument error or bad super blocks and so forth. I can make the first partition anything I want: fat, v-fat, f2fs, ext4 and so forth and that will mount in my terminal without issue, but no matter what I do the 2nd partition always fails to mount. I've also noticed that blkid never has any fs info for the second partition. It gives me the partition UUID and that's all, while the first partition has both part UUID & fs UUID.
I've even gone so far as to just recently get a brand new SD card thinking that perhaps the first SD card was corrupted but I'm still getting the exact same behavior. Also of note is that in gparted when I try to create a secondary partition, I'm unable to mount the second partition so I don't think it has anything to do with my device. I've tried using fdisk, gdisk, parted in the terminal and I've tried using extended partitions and logical partitions and only primary partitions. I've done this before in the past so I know that it is possible.
It almost seems like the SD cards that I have are simply not capable of being partitioned in any way but it's strange that I now have two 512 GB SD cards and they're both giving the exact same behavior so I'm thinking that I'm missing something obvious. Any help anyone could provide as far as trying to figure this out or debug what's going on what I'm doing wrong would be greatly appreciated.
Thanks,
Ryan
only the first partition is mounted from vold. that is normal behaviour on every device. if you want have all partitions mounted automatically install LineageOS.
furthermore, although sdcardfs supports ext4, f2fs, for file transfer via USB MTP afaik fat32, exfat or ntfs is required.
what do you need f2fs partition for? maybe I can point you to workaround.

I don't need anything to mount automatically. I'm saying I can't manually mount these partitions. I also don't need f2fs, that was just an example. I've tried multiple partitions that are just fat, ext4 and many other combinations. Under no partition scheme can I get anything other than the first partition to mount--using the mount command as root.
can you please try gdisk binary from here
https://forum.xda-developers.com/t/...-on-qmobile-z8-with-bricked-dead-emmc.3712171
please post the result of partitioning and formatting.
if you're interested in alternative solution, you can actually format the whole MicroSD card as exfat, and create ext4 partition image on top as regular file. I have done that for my mothers Huawei for Link2SD because it doesn't support adoptable storage.

I have tried with gdisk but I can try with that specific version and report back. I understand we can create imaged file systems, but one of the main reasons I do this is that I find fat partitions are fickle and can easily be corrupted where the whole partition requires wiped. By having a non fat partition I use that as a better backup option where I find it's easier to recover data in case of corruption or other issues. For such use, being tied to the fat FS would still incur the possibility of data loss so that doesn't work for my purpose.
Thanks and I'll report back,
Ryan
oh I wouldn't rely on f2fs for backups it still has bugs and there are no recovery tools for f2fs

Thanks for the suggestion to use gdisk. I downloaded the version you linked, but I still get the same behavior. I believe it is related to the fact that only the first partition gets a filesystem UUID in blkid. I'm not sure what this means, but it seems clear that the second filesystem isn't being properly created no matter what I do.
that's strange, especially the fact you tried on PC too. on the phone, can you create partitions inside a blank disk image just for double check to rule out kernel issue?
I'll give that a try and report back

Yeah I'm able to create an image, partition it into a vfat & ext4, then mount both of those partitions.
can you dd the file into mmcblk1 for testing purposes?

Sorry this isn't clear to me. What am I using to dd into the partition, and do you mean mmcblk1p1/2? As mmcblk1 is the whole disk.
Thanks,
Ryan
yes, I meant the whole disk you created a test file that contains MBR or GPT and two partitions including UUIDs and file systems? If you dd it into the mmcblk1 it should create 1:1 copy of that disk image with two partitions including partition table.
Well I'll be:
Code:
/dev/block/mmcblk1p2 on /data/data/com.termux/files/home/i2 type ext4 (rw,relatime,seclabel) /dev/block/mmcblk1p1 on /data/data/com.termux/files/home/i2 type vfat (rw,relatime,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro)
Code:
/dev/block/mmcblk1p2 23M 46K 23M 1% /data/data/com.termux/files/home/i2 /dev/block/mmcblk1p1 4.9M 0 4.9M 0% /data/data/com.termux/files/home/i1
I can possibly use gparted to just resize those! Any thoughts on what was going on, why this method worked? Hrmm looks like resizing fat could be a challenge, but this certainly gets me closer!
there is also parted binary you can use on phone
I have it and I'm playing around with it, thanks for all your help
