yeah thats absolutly fine
you are not the first to make a thread about this.
comment out the calls to /dev/block/mmcblk0p2 in the a2sd script then change all of the calls in the userinit.sh and user.conf from /dev/block/mmcblk0p3 to /dev/block/mmcblk0p2.

Hello,
How can I format my "ext" partition? (I don't know what a "ext" partition is - I don't have apps2sd) I tried searching but could not find anything, I am sure it is there somewhere though.
Thanks,
Isaac

an ext2 or ext3 partition is a linux partition where apps2sd files are stored. If you don't have Apps2SD you don't have an ext partition ;-)
If you don't have Apps2SD, and you don't know what an ext partition is (which more than likely means you don't have one) why would you need to wipe it? Anyway, LucidREM's script does this for you.

I'm assuming he had a bootloop and someone blamed it on they ext they assumed he had...
This is the GScript I use to clear the EXT partition, however when you do it within Android and oyu use Apps2SD, it will cause the mobile to reboot. Better off running it in the recovery mode or something.
Code:
rm -r /system/sd/*
I have been searching for a clear guide to enabling compcache on 3.9.2, but there is so much info about swap and compcache in this forum i feel like im running around like a chicken with its head cut off.
so far i have pushed 3 different userinit.sh files into my /system/sd with no change.
#free shows 0 swap , #cat /proc/ramzswap says doesnt exist , #cat /proc/swaps comes up blank.
So i searched more and ended up making a 32mb linuxswap partition on my sd and cant figure out how to get that moving either.
Im bogged down with information and have no idea where to start.
Someone point me in the right direction please. Im a swap/compcache noob...
i would like to run them both together, but as i said i need a noob setup guide
Your /system/sd is a mounted ext filesystem, correct?
Push the userinit.sh from here:
http://forum.xda-developers.com/showthread.php?t=542304
Then run it as root and report back any results:
# /system/sd/userinit.sh
i pushed userinit.sh to /system/sd/ with adb
then put in console
su
# /system/sd/userinit.sh and got /system/sd/userinit.sh: permission denied
should i be doing this in the recovery console?
and what did u mean by: is my system/sd/ a mounted ext filesystem?
i did adb remount to mount /system/ as r/w if thats what you meant.
let me apologize once again. i have almost no knowledge of linux commands. a step by step would really save some time. the only thing i hate more than not understanding something, is wasting others time while i do it.

sounds like you did not set up a second partition (or a 3rd for that matter) on your sdcard.
there are many different ways to do this (I prefer gparted in linux), but here's one guide that uses parted in cyanogen's 1.4 recovery image:

im pretty sure you are right. My mmcblk0p2 exists (of course) but when I check # /dev/block/mmcblk0p3 it says not found. And if I # ls /dev/block/mmcbl0p3 it says no such file or directory.
Im guessing i botched something in paragon partition 9. if i remember correctly i put the 32mb linuxswap partition between my fat32 and ext3.
Do u think i should create a new linuxswap partition after my ext3 with paragon9, or is there a workaround for my mistake? does the phone even recognize my poorly placed partition as anything?
thanks so much for your help. after a few hours of reading all these threads Ive come to realize you are the resident expert in swap compcache scripts. as for myself.... not so much
ext should be 2nd partition.
...and linux swap 3rd if you're using it (but it's not needed for compcache -- only as a backing swap).
I'd kill them both and readd with some variant of parted -- i've read that some are having trouble w/ paragon partitioning
Very well then. Ill reformat today and report back.
First of all! Paragon Partition Manager is a FARCE!
Gparted Live CD was awesome. Paragon had my sdcard looking pretty bad. I had 32mb of unallocated space between my FAT32 and EXT3. Even though paragon was telling me it was formatted to linuxswap.
I moved my ext3 over and created a 32mb linuxswap at the end of the sdcard with no loss of data. wow
But sadly, i pushed the userinit.sh #free shows 0 swap and #cat /proc/swaps shows nothing.
Im going to try this >> http://forum.xda-developers.com/showthread.php?t=542899 <<<WORKED!!
What ive learned:
Use Gparted to create a linuxswap partition AFTER your EXT3. Paragon is pure ****.
Get the user.conf and userinit.sh file from the link in above post.
Put them in the root of your sd card
I DID THIS WITH TERMINAL
su
mount -o remount,rw /dev/block/mtdblock3 /system
cp /sdcard/userinit.sh /system/sd
cp /sdcard/user.conf /system/sd
chmod 755 /system/sd/user.conf
chmod 755 /system/sd/userinit.sh
type #sh /system/sd/userinit.sh into console to activate the script.
type #sh /system/sd/userinit.sh -s to get a pretty well detailed report of the goings on.
OOOh being a linux noob is much headache.
Alpapa Thanks for giving me your time and pointing me in the right directions. Thanks man.

I'm a newb as well... so did you chmod either of those files after moving them to ext2/3?
Yes. You have to chmod both of them.
And this works on 3.9.4.
V 0.1 files work best.
http://forum.xda-developers.com/showthread.php?t=542899
And these files come with everything disabled, so you have to edit both of them and enable what u want before putting them on your sd.
0=disabled
1=enabled
Hi, ive searched around but cannot seem to find a complete answer, but basically is there a way to just repartition my linux swap from 32MB to 96MB.
I dont have a linux cd and so if theres a way to do it through ADB or recovery, that would be great.
Thanks.

i'll give you the short answer then i will edit this post with the long answer
short answer.
you use the resize command in parted on your ext3 and linux-swap partition. if you have used parted from the recovery console a few times before this will be easy but i will post through instructions in a minute
Long answer
go into the recovery console. (recovery screen then last option)
then type (if you want to use adb just type adb shell then do the commands)
Code:
parted /dev/block/mmcblk0
print (you will need the start and end points for your ext3 and linux-swap partitions)
resize 2 [start point] [end - 64mb]
resize 3 [start - 64mb] [end]
print (to verify it worked)
quit
upgrade_fs
reboot
there you go.
I have not tested the resize command on an ext3 partition but i do not think (key word think) it will destroy your data on ext3, but back up just to make sure.
to back up your ext3
with adb (since i assume you have it from the first post)
Code:
adb pull /system/sd [dir on computer]
to restore on empty card
Code:
adb shell mkdir /system/sd
adb push [dir on computer] /system/sd
thanks for the great reply. Will test out now and see what happens!
Can anyone verify if this works?
My only concern is the resizing of ext3. Will it cut out any data since I am shortening the partition?

Yes, it works. And yes it *can* corrupt/delete some data from the ext3 depending on how much extra space you have. To be safe, just back-up. The easiest way is doing a BART or switchrom backup (Which backs up you ext) move the backup from the FAT partition to a computer (not necessary but you seem worried about your ext, so just to be safe) resize the partitions and restore your backups.
or just use amon recovery
Thanks for the response guys, I went and started reading about switchrom.
I am planning to do the following steps:
switchrom.sh -s // to store my rom
resize my partitions
switchrom.sh -r
The thread says it stores the nandroid and the app data, I am assuming that means nandroid and ext partition right?

I don't think this is the same, but I am running a hero rom and was wondering what "swappiness" is? I keep reading stuff like "swappiness of 96mb", etc. Is this just referencing the linux swap file size? and with me running a hero rom, what is the best setup for my SD card? I am currently running simply a fat32 partition and an ext3- thanks
Is it a quick adb command? Thus far I have been removing and remaking the partitions. I'd rather not use gparted or any sort of boot disk.
Thanks

That appears to be the same guide I used before, and doesn't seem to say how to format again without deleting the partitions and remaking them. I already have them made, I just want to easily format.

to reformat the ext3 partition

then upgrade to ext4
you dont need to reformat the linux swap partition as nothing remains on there when you shut down
the above code works from terminal, so adding adb shell to the beginning will allow you to do it with adb

Thanks! I'm not familiar with the linux terminal, this is a big help.
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.
