ThIs is the output of df command. How do I increase the avalable in dev/loop0 or may be resize it.
You can use sudo losetup /dev/loop0 to see what file the loopback device is attached to, then you can increase its size with, for example, sudo dd if=/dev/zero bs=1MiB of=/path/to/file conv=notrunc oflag=append count=xxx where xxx is the number of MiB you want to add. After that, sudo losetup -c /dev/loop0 and sudo resize2fs /dev/loop0 should make the new space available for use.
xfs try xfs_growfs instead of resize2fs. To identify if the file system of the loop device use blkid

To to see what file the loopback device is attached to, execute:
# losetup /dev/loop0
then to increase its size you can give, for example
# dd if=/dev/zero bs=1MiB of=/path/to/file conv=notrunc oflag=append count=xxx
where xxx is the number of MiB you want to add.
If the file system is not currently mounted on /, to make the new space available for use you can give:
# losetup -c /dev/loop0
# resize2fs /dev/loop0
If the image you are trying to resize is Ubuntu Touch/Ubports rootfs (which is found in /data/system.img) and you are trying to do this from the device, now reboot to recovery and then after entering in the device with adb shell, give:
# losetup /dev/block/loop0 /data/system.img
# e2fsck -f /dev/block/loop0
# resize2fs -f /dev/block/loop0 # if your fs is ext
# xfs_growfs /dev/block/loop0 # if your fs is xfs
dd if=/dev/null of=/userdata/system.img bs=1M seek=3000 count=0, this enlarge my partition to 3G(original was 2G, sic!)
worked for me, 4Gb
sudo dd if=/dev/zero bs=1MiB of=/userdata/system.img conv=notrunc oflag=append count=4200
sudo e2fsck -yf /userdata/system.img
sudo resize2fs -f /userdata/system.img 1024000
