Your swap partition is /dev/fedora_localhost-swap take a look at how much free space you have in LVM > sudo pvscan > PV /dev/mapper/luks-04cb7d3f-fb60-42ca-9dbe-1ae18433f62d VG vg_dododell lvm2 [196,28 GiB / 7,72 GiB free] > Total: 1 [196,28 GiB] / in use: 1 [196,28 GiB] / in no VG: 0 [0 ] In my case 7,72 GiB free. If you have sufficient free space in LVM you can extend swap partition with: > sudo pvresize --size +6G /dev/fedora_localhost-swap If you do not have sufficient LVM space free, you can shrink some other partition, like /home, you can do that in single user mode, or logging in with root from CTRL+Alt+F2 and without other active users, umount /home, restrict filesystem (example 11Gb) , restrict partition (example 10 Gb), extend filesystem to max partition. At this point you can extend the swap LVM partition. When you have extend the swap partition, you must extend the swap area with this command: > swapoff /dev/fedora_localhost-swap > mkswap /dev/fedora_localhost-swap > swapon /dev/fedora_localhost-swap Hope this help Ciao -- Dario Lesca (inviato dal mio Linux Fedora 22 con Gnome 3.16) -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
