FS not resizing.

[IriDium]

NOTE: This is from a very early release - XBMC13.2 Dec 2014.

The system was backup up using xbian-config to an image. Due to an error, the backup was restored to the SD card and the system booted.

However, the FS does not resize and thinks it is only 2G whereas the card is 4G.

Is there anyway to force the resize or can I do it on a live BTRFS system?

Forcing resize: don't know

You can do it while fs is mounted

1) check partition size
sudo fdisk -l /dev/mmcblk0

if size is already max then continue with step 5

2) remove swap part if exists (should be partition 3)
sudo swapoff -a
and then run sudo fdisk /dev/mmcblk0 and remove swap part
don't exit fdisk

3) enlarge root partition (should be partition 2) and add new swap partition
start fdisk if not already running
The trick is removing the existing one and create a new one with exactly the same start block and max size minus 250M for swap part
Add swap partition, use rest of disk for this
save changes to disk and exit (command w)

4) reload partition table into kernel
run sudo partprobe
if partprobe complains anything, you have to reboot before step 5

step 5) resize root fs and add swap
resize root fs
sudo btrfs filesystem resize max /
sudo swapoff -a
sudo mkswap /dev/mmcblk0p3
sudo swapon -a

Unfortunately that didn't work. fdisk was throwing up errors about the disk and wouldn't let me delete the partition.

Trying an alternative image back and see if that is any better

So this was the reason for resizing failed

More than likely - a later backup image worked as expected.

I moved my SD-card to the USB stick on a RPI 2b device. This works fine. However, the root partiion doesn't want to resize to the size of the USB stick. xbian-config doesn't support the resize, since it is supposed to resize by itself.

How can I make it resize?
(I checked some old forum topics, and I checked my /boot/config.txt The following lines look different than in those forums:

Code:

# see /etc/default/xbian-initramfs
#initramfs initramfs.gz  followkernel

You have to enable initramfs in Kodi's XBian-config gui, category System, remove swap partition manually (if exist, see above) and reboot.

With the fdisk command I checked the USB-stick that holds my OS:

Code:

@xbian ~ $ sudo fdisk -l /dev/sda
[sudo] password for xbian:

/dev/sda2       206848 2609151 2402304  1.1G 83 Linux

It seems like this disk doesn't hold a swap partition.

Then I checked the Xbian GUI:
Xbian - System - (sub topic System) - 'Use of initramfs' = required

I put it on 'always' and rebooted. This doesn't do the trick.

Hmmm, but it should There are cmdline parameters to disable resize partition and creating of swap, but I don't believe that you have set them

Have you checked if initramfs is enabled in /boot/config.txt now?

[jakenl]

Yes I checked, the hash sign is still in front of it. The text is the same as described 2 posts back

Ah, that's what I assumed

Did you save the setting you changed? It's not enough to change setting, you have to go to next/previous setting in XBian-config GUI before you'll be asked if you want to save setting or not.

Another question:
Are you booting without sd-card? If not, maybe wrong /boot partition is mounted

I forgot the next/previous thing and after a reboot, the # sign was gone indeed. However, the partition was not resized.

Code:

# see /etc/default/xbian-initramfs
initramfs initramfs.gz  followkernel

It is a RPI 2b, therefore it needs a SD-card to boot from.

Extract from the fdisk command: fdisk -l:

So we have the first error:

You're booting from sd-card (/dev/mmcblk0p1) but when system is up this partition is not mounted to /boot. /dev/sda1 is mounted instead. This is wrong and will produce serious issues in case of installing/updateing packages!

Please correct this in /etc/fstab and try again

[Nachteule]

Btw, if you want to use boot partition from your external usb device, you could prepare an sd-card as documented in this article

I tried this a couple of months ago with an Pi2, and it's working great

I had to repeat the process above 2 times, went back to a backup of this SD-card in between, but at the eind it works as expected: only bootcode.bin on a FAT formatted card and it boots further from USB. Great!
With df -h I checked available file size and my full 32Gb is now accessible. Main issue solved. By running sudo fdisk -l I also found a SWAP file mounted on /dev/sda3, so that seems good too now!

Very well possible, good that you found a reason! (although I only followed the backup to USB procedure from xbian-config at the time)

Please help me with my /etc/fstab content. I see for instance 2 identical lines with an UUID. With your help I might streamline my fstab as well and have a proper functioning system left.
