Recreate a bigger openwrt disk image based on the official original disk image - #2 by vgaetera


thx, you are my hero!

I did following steps, maybe it's not correct but it worked for me:

/var/lib/libvirt/images/qemu-img resize -f raw openwrt-*.img 300M

#log in via ssh to openwrt
# Install packages
opkg update
opkg install parted losetup resize2fs
# Identify disk name and partition number
echo -e "ok\nfix" | parted -l ---pretend-input-tty
# Expand root partition
parted -s /dev/vda resizepart 1 100%
# Apply changes

# Map loop device to root partition
losetup /dev/loop1 /dev/vda
# Expand root filesystem
resize2fs -f /dev/loop1
# Apply changes
