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(a)lists.fedoraproject.org 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?

I made some tests: using the command pvscan I get this output: ----- PV /dev/sda2 VG fedora_localhost lvm2 [931.02 GiB / 64.00 MiB free] Total: 1 [931.02 GiB] / in use: 1 [931.02 GiB]* / in no VG: 0 [0 ]* ----- what means this ? I can think this output concern ALL the Volume Group of LVM: And the row up seem to indicate that they are (only) 64 MB free *(but what means "/ in no VG: 0 [0 ]" in the row down?)* I made the same test (inside the lvm environment) using the command lvscan: this time I got this output: ----- lvm> lvscan ACTIVE '/dev/fedora_localhost/swap' [7.75 GiB] inherit ACTIVE '/dev/fedora_localhost/home' [873.21 GiB] inherit ACTIVE '/dev/fedora_localhost/root' [50.00 GiB] inherit ----- OK! the total is 930.96 ------ that the second control confirm the former one, and it shows also more details... But what does not enter in my head, is the fact that the (huge) quantity of free space (845449680 ) of the "home" partition is not reported when I used the command pvscan : ...

The free space is into filesystem, and not into LVM. The free space into filesystem is not useful vie LVM, You must be transferred a little bit of free space from filesystem to LVM Shrink filesystem then shrink LVM partition. When you install Fedora, and do not do a manual partition, anaconda use all disk space for all default partition, swap(8Gb), /(50 Gb) and /home (all the rest), 900Gb in your case. Then now, you have a huge /home, filling for 9Gb (2%), and 0 Gb of LVM free for extend other FS or Swap. When I install, I do not allocate all space but only a little bit (or what I have need) for my filesystem. Because, after, is more simple extend rater than shrink. Now I suggest you to shrink /home to 200 Gb (or what do you want) and leave more free space to assign where it's necessary or create new volume. To do that follow the my previous generic procedure. If you have ext4 FS (blkid is your friend), after you have unmount /home, the command are: sudo umount /dev/fedora_localhost/home # umount fs sudo fsck.ext4 -f /dev/fedora_localhost/home # check fs sudo resize2fs /dev/fedora_localhost/home 190G # shrink fs to a little bit less what you want sudo lvresize --size 200G /dev/fedora_localhost/home # Resize partition to what you want sudo resize2fs /dev/fedora_localhost/home # extend the FS to partition size, what you want. sudo mount -a sudo pvscan At this point you'll have a lot of free space to do whatever you want. *IMPORTANT:* *Before of all, do a full backup of your important data, if I or you have written something wrong , you will need to reinstall from scratch* Ciao. -- Dario Lesca (inviato dal mio Linux Fedora 22 con Gnome 3.16) -- users mailing list users(a)lists.fedoraproject.org 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?

lvm lvreduce -L650 G /dev/fedora_localhost

# lvresize --size 651G /dev/fedora_localhost/home worked fine.. And now pvscan give me 220 G free . -------------------- But now I have also problem growing the swap partition: The command pvresize --size 20G /dev/fedora_localhost-swap give me another error : "prvresize unrecognized option --size" What is wrong there ?

in order to grow the swap partition, I made this: ============ resize2fs -p /dev/mapper/fedora_localhost-home resize2fs -p /dev/mapper/localhost-home 700G lvresize --size 651G /dev/fedoralocalhost-home ----------- the command pvscan gave me this output: PvV /dev/sda2 VG fedora_localhost lvm2[ On Fri, Jun 26, 2015 at 7:58 AM, Ed Greshko <ed.greshko(a)greshko.com&gt; wrote: > On 06/26/15 12:57, Angelo Moreschini wrote: > > # lvresize --size 651G /dev/fedora_localhost/home worked fine.. > > > > > > And now pvscan give me 220 G free . > > > > -------------------- > > But now I have also problem growing the swap partition: > > > > The command > > pvresize --size 20G /dev/fedora_localhost-swap > > > > give me another error : > > "prvresize unrecognized option --size" > > > > What is wrong there ? > > man prvresize will show an example. > > -- > Sorta what I want to say when folks habitually complain about Fedora - > https://youtu.be/ZArl8fTfub4 > -- > users mailing list > users(a)lists.fedoraproject.org > 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?
