Not possible to expand SD card - joehc - 4th Mar, 2018 10:38 PM
Hello
I've flashed a backup image to a rather big sd card (64gb) and im trying to expand the root partition, but with no luck.
I have followed the other guides but I still cant managed to expand the partition.
In /boot/config.text, I have:
Terminal
initramfs initramfs.gz 0x1500000
In /etc/default/xbian-initramfs, I have:
Terminal
FORCEINITRAM=yes
And
Code:
sudo fdisk -l /dev/mmcblk0Terminal
Disk /dev/mmcblk0: 59.5 GiB, 63864569856 bytes, 124735488 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes

/dev/mmcblk0p3 15175680 15677439 501760 245M 82 Linux swap / Solaris
Is it not possible to expand /dev/mmcblk0p2?

Hmmm, it should work, but you have already swap partition, that's an indication for root fs expansion has been already done, but probably with the wrong size.
When you start your Pi, do you see the splash message sd card resize..., and/or fs resize... and/or creating swap... ?
You could start that process again if you remove swap partition and reboot again
Before removing swap partition, you have to stop swap first:
Terminal
sudo swapoff -a

How do I remove the swap partition? Can I do it without using gparted on another machine e.g.?

Sure, you can do this:
you have to run fdisk and delete partition 3
Terminal
sudo fdisk /dev/mmcblk0
Inside fdisk, you can run command 'p' to display all partitions and 'd' to remove partition (fdisk usually defaults to the last partition, this is the one you have to remove)

I am newcomer on the forum here, but a long time user of xbian.
I'm piggy backing on this thread as I cannot create a new one yet.
I'm looking for the best way to downsize the root partition on the sd card.
I need to be able to clone this 32GB (with my vpn, trnasmission with kill-switch,sickrage,...etc) to a 8gb card.
I also don't know if the automatic expansion is happening automatically only at the first boot and if not how to prevent it from resizing again.
Terminal
xbian@xbian ~ $ sudo fdisk -l /dev/mmcblk0

any help appreciated. Also I realized you don't have any crypto donation address. (any reason why)
I would happily send you guys money for a 6 pack with bitcoins or even better through lightning network.

The easiest way to shrink your existing installation is to make an image backup.
Start xbian-config, and run menu point 6 (xbian copier), and select file:/the-position-you-want/the-image-file-you.want as destination. This image can be flashed to your 8GB card and boot from that card
Automatic resize is done always, it is part of the init procedure which resides in the initramfs part. You can disable this behavior by adding the noresizesd parameter to the kernel command line, see here
