How to Install Fedora 25 Minimal

JaredBusch

Note that the fedora in all those commands to use the space is because that is the name of the volume group

vgdisplay

Does the same principle apply if I made the default disk 4 or 6TB in size?

That is really just up to how you want to manage it.

At that scale, I would personally want it to be a separate virtual disk. But that is honestly only because I have more options for recovery. It is easier to work with a disk that you know have nothing but data than tryign to attach a once bootable disk to a new VM, etc.

None of that has anything to do with the host and how it mounts the space.

Edit: but evcen as a separate virtual disk, you will format and mount it the same way. Well, barring it being a different device (/dev/sdb).

Thanks, that's kinda what I thought, just wanted to make sure.

Wow so pre-configured addons and choices compared to Centos 7 Minimal installation.

Not the same thing at all. The CentOS install media is only for minimal, this is a net install and you choose which method you want.

The full CentOS media has choices too.

A CentOS example would be...

When selecting guest agents, it doesn't automatically installs hyperv-daemons.

JaredBusch

@black3dynamite I noticed hyper-v did not show a good agent. Did not have time to test.

Is Fedora ext4 by default? Can you choose XFS during install?

XFS, EXT4, BtrFS... you can configure basically anything during the install.

JaredBusch

Yes, by default it is ext4 if you let it partition as shown.

StrongBad

Why ext4 as a default? Feels like they are moving backwards there. They made the move to XFS from ext4 already.

@JaredBusch Let's say you want to use this VM as a file server.
Is it better to create 2 disks (1 for o/s + 1 for storage) or just one big ass disk?

As this example showed, I had a 127GB disk because I let Hyper-V Server 2016 use its default.

Fedora only took 17GB of it. 2GB for swap and 15GB for root.

The rest is sitting there waiting to be used however you want.

So all you have to do is make the space usable.
#create a logical volume named data
lvcreate -l 100%FREE -n data fedora

#format it to ext4
mkfs.ext4 /dev/fedora/data

#make a directory to mount it
mkdir /data

#mount it
mount /dev/fedora/data /data
Obviously you will want to have this mounted on reboot, so add it to /etc/fstab
nano /etc/fstab

#add this
/dev/fedora/data /data                    ext4    defaults        1 2

edit: If I have 2 virtual disks (1 for o/s + 1 for data). Anyone have a simple "how to do this" guide on the 2nd disk: /dev/xvdb or /dev/sdb ? (I read some guides on the 'net, thy all seem long & winded)

No idea, but what you are seeing in this thread is what you get from a 127GB vhdx and let Fedora do automatic partitioning as shown above (edit: copied below)

Off the top of my head even, let's go!

pvcreate /dev/xvdb
vgcreate vgname /dev/xvdb
lvcreate -n 'lvname' vgname -l 100%FREE
mkfs.xfs /dev/vgname/lvname
mount /dev/vgname/lvname /mountpoint

If you add an xfs volume to fstab, it's recommended to make the last two options (dump and fsck) zero. Yeah, xfs can really speed up boot times if you're switching from another file system that needs to run an fsck at boot.

@travisdh1 Thx, will check out your video.

Fedora Server uses EXT4 (/boot) and XFS (/root). Fedora Workstation uses EXT4.

guest-agents installs packages of open-vm-tools and qemu-guest-agent.

Typing this command will so those packages:
dnf groupinfo "guest-agents"
