 /swapfile       swap    swap    defaults        0       0

set permissions:

 chown root:root /swapfile
 chmod 0600 /swapfile

discs over 2gb need a modern controller. use these commands to activate a disc on a PCI-express controller:

show controller details and ID:

lspci -nnk

output, e.g.: SATA controller [0106]: Marvell Technology Group Ltd. Device [1b4b:9125] (rev 11)

Associate ID with the AHCI driver:

/bin/echo 1b4b 9125 > /sys/bus/pci/drivers/ahci/new_id

now the disc should appear in

fdisk -l
