Just installed link2sd earlier (formatted partition as ext3). Wanted to flash a different rom. Trying to backup my phone, and clockworkmod tells me it can't mount sd-ext. Anyone know a reason and/or work around?
I think CWM works only with ext4 partition AFAIK. So, you can re-partition your sd card to a ext4 partition using CWM, or you can format the ext partition only to ext4 using a computer.

which version of CWM have you got?
3.0.2.4, which I've used for a while now, always tries to back up my 6GB ext2 debian partition unless I remember to change cards first. no way I leave room in the vfat partition to back up that much data.
I'll put it up on 4shared if you want it.

Guess when I get home I'll copy the contents to computer, reformat, and copy back. Hopefully link2sd will notice the formatting has changed and reset itself

Doesn't work with extra either. Version 3.2.0.1 I believe it was.
Guess it doesn't really matter, can just use titanium since its all app stuff on there anyways...

i use CWM to back up my 512MB ext2 partition for my data2ext all the time (with the rest of the backup) and it seems to have no problem, and just to check i just mounted the partition in mounts and storage and it mounts fine. I know some recoveries ive used in the past on other phones would have problems with partitions that were not in 64-128-256-512-1024 MB, etc. format because of block size issue errors that i would get (when mounting or trying to set block size to 4096). I also found that when partitoning/formatting to ext2/3/4 some programs do not properly write the drive formatting and certain systems/recoveries/apps could not properly read them on the android. the best most consistent (android friendly) formats that i have gotten to date were in ubuntu (or any other) linux using "gparted". It seemed to always be the best and usually better than the format done by the phone recovery. Hope this helps. Sorry to drone on and on.
Partitioned originally with gparted. Have since resized to be 2048, and set its label to 'sd-ext'. Now instead of getting an error saying sd-ext might not be supported on my device, it just gives me a generic 'error mounting sd-ext'
I've had ext partition mounting problems before, I'm not sure if the cause is something to do with vold or what, but
after unmounting a sd card to exchange it with another one, it changes the device partitions in /dev/block like
/dev/block/mmcblk1p2
for the sd-ext partition instead of the normal
/dev/block/mmcblk0p2
you can see if this has happened by
Code:
ls /dev/block
in adb shell.
to mount it manually, if the numbering is off,
Code:
mount /dev/block/mmcblk1p2 /sd-ext
I've only had this happen with android running, but it might work in recovery too
Switched over to using data2ext. Mounts the 2nd partition as the /data partition instead of /sd-ext. Can manually mount 2nd as /sd-ext from within rom, but it doesn't carry over to recovery.
A possible solution... Create a symbolic link pointing /sd-ext to the 2nd partition? But then again, since /data now points to 2nd partition, is recovery picking up on that unknowingly and backing up the 2nd's contents when it thinks its backing up the normal /data?
I suppose I should investigate.
Edit: Yep it does backup the 2nd partition, thankfully. Just tried to install a theme made in UOT Kitchen, it borked some stuff, and the restore worked.

Basically you have to create partitions on the SD for /system, /data/ and /cache (with ext2/3 filesystem) and copy the necessary files there from the Galaxy S firmware then you can use that, but with the kernel in the tutorial section it won't work. You need different init.rc to mount these partitions instead of the loopback images

Questions go to the Q&A ..
I gave it a try of formatting the external microsd to ext3/4 but it appears that vold on the stock rom (and roms based on it) does not support ext4
If you neext ext3/4 support on the microSD you will need to use a CM9 based rom
Hi,
im using CM10. How did you do that and are there any restrictions???
How do we format our cards to ext4?

It seems that auto mount its not implemented for ext file system on android. At least I discovered that on my tablet when I tried to copy files on an ext3 hard drive. It's a shame as ext is the default filesystem for android...
I had to mount it manually. There are guides on the net. It's the classical mount Linux command. To automate it you should add a script in init.d folder. There must be examples on the net too.

Thirty seconds search on Google.
I can't seem to get my partitioned SD card to work with Link2SD on CyanogenMod 9.1.0. I used the kernel that came with the zip file, I am using ST17i Satsuma. Can anybody help me figure out why it isn't working? As far as I know, the kernel that's included on http://get.cm/?device=satsuma&type=stable is the FreeXperia kernel. What are things I can do to make it accept Ext4?
I just installed a 5.0 ROM from having been on 5.1.1 stock and discovered the ext4 formatted sdcard is not being mounted. It seems ext4 may not be natively supported in 5.0.
Is there an app I can install that can fix this? I found various "sd card fixer" apps but none of them worked. I also found a script on here but it seems it may not be fully functional (pls correct me if I am wrong).
Any help would be greatly appreciated, thanks.
