[Q] how to mount ext2 partition on external sdcard ?

I managed to format my old ext4 1gb partition
(ex mimocam lagfix) to ext2. Something to try with...
It's done, but i can't see it by making a df -h via adb shell.
am i missing something ?
note : froyo jpc with froyo stock kernel
ext4 partition was mounted at boot using mimocam ext4 kernel
is froyo from spc kernel able to mount ext2
(i think so, RyanZa lagfix use it..)
Thanks

[Q] HELP! cannot convert EXT2 to EXT3

I have created EXT2 partition of 1024 GB, after that try to convert from recovery (Amon_RA) to EXT3 and got no errors.
On the nexus I see:
/dev/block/mmcblk0p2 on /sd-ext type ext2 (rw,noatime,nodiratime,barrier=1,data=
when try to convert using command shell - adb shell sdparted -ufs ext I got error that the partition is already EXT3

It's very possible that the partition is already EXT3, but the ROM you're using doesn't recognize it correctly.
What command did you use?

mount, im with MIUI rom but also had this with CM nightly

I use EXT2 and it works fine with MIUI or Darktremor Apps2sdext

I know, everything works fine but my partition is EXT3 and recognized as EXT2 by the ROM

Try to take out the card and read by any Linux PC, check that the EXT3 is indeed valid.
If yes - disregard the mount message. Might be some Toolbox issues.
I've just checked my own report, and unsurprisingly, mount reports my EXT3 as EXT2. No ill effects, though. Using Apps2EXT for a long while now. And I'm on Enomther's, and just checked - Busybox 1.17 mount does the same (lack of) recognition.

do configurate it correctly? the partition of sdcard must of the following (Stock kernel)
FAT16/32, EXT2 or EXT3
Custom kernel (Swap is not compulsory)
FAT16/32, EXT2, EXT3 or EXT4, SWAP
and for the mounting of EXT2 and EXT3, you must install the stock modules for stock kernel

Why my ACE does not mount SD-EXT at boot??

Hi there,
I have a Galaxy ACE with Stock KTM Rom , CWM5 , and rooted with CFRoot b83 (b84+b84fix does not work on my KTM rom...dont know why)
I partitioned my 4Gb SD with CWM: 512 for Ext , 0 for Swap and rest for Fat32
I have even tried to format with Mini Partition Tool: Fat32 Primary and EXT2 or EXT3 Primary (4kb cluster size)
I can mount /sd-ext on recovery , even format it, etc.
But.. I have many problems with **2SD scripts, and I think that I found the reason: SD-Ext is not mounted.
I have installed Terminal Emulator, and I get this:
# mount | grep sd-ext -> nothing happens (it should show information)
# df -> /sd-ext is not shown
What can I do??
I know that Link2sd app works with Fat32 + Fat32 partitioned cards, but I need sd-ext to work , so Link2Sd is not a solution for me.
THANKS A LOT!!

You should repartition your sd-ext with cwm...it will auto partition it into ext4...dta2sd works with that...since you are using cf-root...your have a tweaks manager right?try to enable auto start dta2sd at boot...for a sd card, the one for general storage should b in FAT32, sd-ext should be in ext4 (although certaim scripts can work with other formats, but this is working better and faster, so why not?)...Hope it helps...

I have tried to make the repartition with CWM , into EXT4, and I have enabled auto start dta2sd at boot ...
But sd-ext is still not there.
I think that CFRoot is not enabling init.d support on my stock Rom.
Thanks for your reply..
Any suggestion will be welcomed!!

[Q] /data/app-lib in android 4.2.1 - link2SD will cause errors ?

I'm trying some custom roms, derived from cyanogen 10.1 i.e. jellybeam 4.2.1 (a new flavour...)
here i see a new folder in my filesystem: /data/app-lib
where are extracted libs from installed apk.
In previous version this files were in /data/data/<app_name>/lib
I 'll have some problems when using tool like Link2sd - that replace this files with simbolik links - now those paths doesn't match anymore, until link2sd will be updated....
Could someone confirm this ?
thank you...

are you sure link2sd is not updated for this thing
jb is out quite a time ago and I think link2sd is updated to ticker this out
i have android 4.1.2 rom but it doesn't have any app-lib folder in /data partition

for what i see, this difference exist from in 4.2.1=>cyanogen 10.1 (after 4.1.2=>cyanogen 10)

link2sd works for me on cm10.1 (android 4.2) so i highly doubt its not updated...

Hi!
I have the same problem on gio cm10.1
link2sd.info/faq
I found in the middle of page:
Q. Library files that I linked get unlinked after restarting my phone, why?
See link for answer, but at the end of that topic u can see this:
"You can use "relink lib files at boot option" as workaround."
What isn't help for me, because the free space stays at the same Mbs.
After relink lib files I recommend to use a root browser to delete the unnecessary folders.
But the sad news is that you need to do this after every reboot.

Yeah that's normal
You will need to make a script and have to out in init.d
In that way everything would be done automatically

Could you give some advice of how can we do it, please?
edit: I found the 11link2sd file in the init.d folder which contains the following:
Code:
#!/system/bin/sh
#added by link2sd
LOG=/data/link2sd-11link2sd.log
echo "$(date) mounting..." > $LOG
mount -t ext2 -o rw /dev/block/vold/179:2 /data/sdext2 1>>$LOG 2>>$LOG
mount -t ext2 -o rw /dev/block/mmcblk0p2 /data/sdext2 1>>$LOG 2>>$LOG
mount >> $LOG
echo "$(date) mount finished" >> $LOG

Maybe the folder is not mounted because you have chosen the SD partition as ext2 (in link2sd app)
Where your sdcard partition could be of ext3/ext4
Review this

In minitools PW i partitioned the 2nd part to ext2 because the stock GB does not support ext3/4. (I have a class 4 sdhc card)
So now i heve to repartition my sd or simply change the setup in link2sd to ext3/4?

Who says ext3 is not supported (don't think so)
Try to run that app at boot with the help of script manager
It may work

Uhh... I'm a newbie yet.
I'll try.
Thank you!:laugh:
When the first time i set 2nd parition to ext3 on stock GB 2.3.3 and tried to connect to link2sd it said "your device does not support ext4!"
So now i have to repartition my card on pc?
the ext support depends on which kernel i have?

Yayy!!! Repartitioned the ext2 to ext4 and everythings ok.
After repartitioning i needed some reboot and relink in link2sd, but now it's awesome. :good:
After the third reboot my memory goes lower and lower. Now i have 93,43mb free space in /data with (all) 52 apps linked.
I made a backup in TB before the partitioning and restored later.
DSP manager,E-mail,Exchange2 and lockClock apks were deleted too and the market app was converted to user app so the system' size goes lower too. :laugh:
