Further if I try to delete partition /dev/sda6, the error is
'unable to delete /dev/sda6! Please unmount any logical partition with a number higher than 6'.
So when I tried to unmount /dev/sda8, the error message is:
# umount -v "/"
umount: /: target is busy
'unable to delete /dev/sda6! Please unmount any logical partition with a number higher than 6'.
