swapon \/swapfile echo “\/swapfile swap swap sw 0 0” >> \/etc\/fstab The problem with fallocate(1) is that it uses filesystem ioctls to make the allocation fast and effective, the disadvantage is that it does not physically allocate the space but swapon(2) syscall requires a real space. Reference : https:\/\/bugzilla.redhat.com\/show_bug.cgi?id=1129205<\/p>\n I had faced this issue earlier with my box too.
