Hi all im new to Fedora ( and Linux ) . Can you please answer my questions on the partitions I have

[devtwo@localhost /]$ df -h
Filesystem               Size  Used Avail Use% Mounted on
/dev/mapper/fedora-root   88G   70G   14G  84% /
devtmpfs                 3.9G     0  3.9G   0% /dev
tmpfs                    3.9G  612K  3.9G   1% /dev/shm
tmpfs                    3.9G  1.1M  3.9G   1% /run
tmpfs                    3.9G     0  3.9G   0% /sys/fs/cgroup
tmpfs                    3.9G   76K  3.9G   1% /tmp
/dev/sda7                477M  122M  326M  28% /boot
/dev/mapper/fedora-home  674G  349G  291G  55% /home
  1. What are the tmpfs partitions And can I reduce their size ?
  2. How can I increase the size of the root partition Gparted shows a FAT32 partition on /dev/sda2 which has a boot flag and is not showing up here ?
  3. This machine used to have win 8.1 but not anymore. Can I get rid of that partition?
  4. Gparted shows a different info from df -h, any reason for this ?

The FAT32 partition is your EFI System Partition - see the 'Label' column. If you remove it, you will be unable to boot Fedora or any other installed operating system. Leave it alone.

  1. tmpfs is a ram-based filesystem, it's used because its way quicker than storing temporary files in a /tmp directory that then has to be cleaned out after a crash. The size of these partitions can be set by editing their entries in fstab, see my comments below.

  2. The partition isn't showing up because it's not mounted. You can used gparted to reduce the size of the FAT32 partition and increase the size of your root, but if there's an OS installed on that drive, you may find it safer to boot into that OS and resize it from there.

  3. If the FAT32 partition is your old Win8 drive, and you're sure you don't need it, then by all means delete it. gparted should be able to manage that for you. You can re-allocate the space to your Linux system.

  4. gparted output may be confused by the presence of logical volumes and filesystem artefacts that it doesn't understand.

Your filesystems are defined in the file /etc/fstab, reading that will tell you plenty about your system. You can change the size of tmpfs filesystems by editing (or providing) a size=nbytes in its options.

If your system is using Logical Volumes, you may find it easy to add extra space to your Logical Volumes using the LV tools rather than using gparted - although using that tool to remove non-Linux partitions is not a bad thing if it marks the space as empty.

You may also find it helpful to understand some of the tools you're using here, here are some resources that explain stuff much better than I can on this help website:

And last, but not least, always remember when playing around with your partition table keep a backup of any valuable data before you start because it'll be too late once it's been deleted because you accidentally deleted the wrong partition. This usually means backing up any of your own files from your /home/<user> directory and any changed configuration files in /etc (or anywhere else you're keeping configs). Anything else can be sorted out by reinstalling, updating, and re-applying your config settings and restoring your home directory.</user>
