[HOWTO] Resize Your Linux Partition LIVE

[mdrjr]

This guide will teach you how to properly resize your Linux install partition without anything but the OS booted on the ODROID Board.

This guide works for eMMC or SDCard.
Make sure that you have only the eMMC or SD connected at this time.

Download the script attached on this thread

and type:

Code: Select all

chmod +x resize.sh
sudo ./resize.sh


You'll see the following output:

Code: Select all

root@odroid:~# sudo ./resize.sh
Found the start point of mmcblk0p2: 266240
Ok, Partition resized, please reboot now
Once the reboot is completed please run this script again


reboot the board now, just type sudo reboot

Once the boot is done, run the script again!

Code: Select all

root@odroid:~# sudo ./resize.sh
Activating the new size
resize2fs 1.42.5 (29-Jul-2012)
Done!
Enjoy your new space!


You are done now, your / partition is using the entire space of the disk

Finally I've been doing this forever.
btw, it works with the 3.0 kernel, and for the XU as well (as long as you have kernel support, and there are big chances there is kernel support for ext3 and ext4).

And why you never posted here explaining how to use?

I've been doing this since the first boot of 3.8 on my -X.

Edit: Yes, it works on XU too. So.. all odroid's should be covered now.

We were talking about it here: viewtopic.php?f=9&t=1239&start=40#p10406
I was complaining to neagix that switching to ext2 for rootfs you cannot to this, since only ext3 and ext4 were supported in the kernel

[osterluk]

Nice. This will help a lot of people.
Thanks

[wmseward]

Nice simple script. Code review is easy!

Now I want to write a script.

Thanx!

[TSC]

I get:

Code: Select all

open: No such file or directory while opening /dev/mmcblk0p2

.

Any idea how to resolver this? I have Lubuntu 13.10 CodeMonkey U2 image installed in the eMMC through win32diskimager. Image runs good in U3 and I can open the content in Windows. But no luck on mounting this image in Ubuntu 13.10 (installed in my laptop). Need the partition resized since I have a 16gb eMMC and can only use 8GB of the image above.

Running dmesg on the cmd line gives me:

Code: Select all

[  604.675367] mmc0: BKOPS_EN bit is not set
[  604.678521] mmc0: error -22 whilst initialising MMC card

gparted doesn't give me any partition at all besides the one /dev/sda1, /dev/sdb/ and /dev/sdc/.

Thank you! Any help would be great!

Best regards

Do you have a microsd at the same time ? If so, remove it.. resize and it will work..

No microsd inserted. Just the emmc connected to the sd card reader of the laptop through the emmc-to-usd adaptor. This adaptor is also inserted in a usd-to-sd adaptor.

Ugh. This script is made to be executed on the board with the OS running not on your PC

Lol a sério? Desculpa nao tinha percebido! Vou experimentar e depois aviso. Saudações de Portugal

[labsin]

This script is a bit dangerous. I have a setup with only one partition so it doesn't find the start byte, so the it just enters 0 when asked for the start byte.
It needs some checks etc.
Might be best to just post the steps.

My C1 does not want to resize.
Took the image from 5th of feb and wrote it on my 32 GB SD card using the Windows tool.
Device is booting up fine and everything is good so far.

Code: Select all

:~$ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/mmcblk0p2  4.3G  4.0G  184M  96% /
none            4.0K     0  4.0K   0% /sys/fs/cgroup
udev            420M  4.0K  420M   1% /dev
tmpfs           425M  4.0K  425M   1% /tmp
tmpfs            85M  2.6M   83M   3% /run
none            5.0M     0  5.0M   0% /run/lock
none            425M   76K  425M   1% /run/shm
none            100M   24K  100M   1% /run/user
/dev/mmcblk0p1  129M  7.2M  122M   6% /media/boot


So I took the script "resize.sh" and started it.
Output

Code: Select all

:~# ./resize.sh
Found the start point of mmcblk0p2: 266240
Ok, Partition resized, please reboot now
Once the reboot is completed please run this script again


So I rebooted it and run it again.

Output:

Code: Select all

:~$ ./resize.sh
Activating the new size
resize2fs 1.42.9 (4-Feb-2014)
resize2fs: No space left on device While checking for on-line resizing support
Done!
Enjoy your new space!


fstab info:

Code: Select all

:~$ more /etc/fstab
# UNCONFIGURED FSTAB FOR BASE SYSTEM

UUID=e139ce78-9841-40fe-8823-96a304a09859   /   ext4   errors=remount-ro,noatime,nodiratime      0 1
UUID=6E35-5356   /media/boot   vfat   defaults,rw,owner,flush,umask=000   0 0
tmpfs      /tmp   tmpfs   nodev,nosuid,mode=1777         0 0


Hmmh, have not found any useful hints.

Anyone?

[mdrjr]

Use ODROID Utility to do that.

[rakekniven]

Done that in the meantime. Works pretty well.
Thx.

[labsin]

loboris also has a nice fs_resize script in his Ubuntu/Debian distro's that deals with 1 partition, does some echo'ing and adds a init script for resize2fs on reboot.

I attached it here. But it's not mine, it's from http://forum.odroid.com/viewtopic.php?f=112&t=8075

Use ODROID Utility to do that.

for the newbies like me : it's on the Ubuntu desktop !

[atodea]

Thank you.
It works like a charm!

I used the "Odroid Utility" to resize the partition on my C1. It does nothing. Running `df -H` still shows that /dev/mmcblk0p2 is still only 4.6G even though I'm using a 32GB card.

How do you expand the root partition on a C1?

Start by posting on the correct place and attaching the LOG on /root.

Did you rebooted after the resize?

[ceVoIX]

Hi,
I am a linux beginner, in which folder i have to grab the resize.sh file?

[meveric]

doesn't matter as long as you start it as root (or with sudo)

[inf3rno]

I would rather use gparted on my PC with Fedora 23 and a micro SD - USB adapter. Is there anything special in the partition resize process which requires this script?

[meveric]

nope.. using gparted works just fine

[Mikitz]

Ugh. This script is made to be executed on the board with the OS running not on your PC

This is an easy fix. Simply run the following from a terminal.

Code: Select all

wget -O resize.sh https://forum.odroid.com/download/file.php?id=502

Then, all of the commands in the OP will function properly.

Piece of cake, it is
