The system is saying that xvda2 is mounted.

Yet I have no idea how it's mounted.

So, just grep /etc/mtab for xvda2.

So, I think you can safely force the pvcreate.

DustinB3403

@Francesco-Provino when I try for force pvcreate using

pvcreate /dev/xdva2 -ff it results in

Oh, xvda2 is your root filesystem. What's the output of fdisk -l? It looks like it should be xvda3

xvda1 is the boot partition.

Did you create a partition for the free space? You need to use fdisk to make a third primary partition.

DustinB3403

@stacksofplates ok, following this here.

Dumb question, would it be easier for me to simply add a separate drive, and then extend the root drive into the new drive?

Maybe.
You can skip the fdisk stuff and add a whole new block device to LVM if you add another virtual disk.

@Francesco-Provino I'm fine with a separate physical device, so long as the system uses it as a single device.

You can actually move everything to the new drive using lvm. Tho I don't remember how to do that offhand, I'd have to look it up.

OK so this is what I have with a new "physical" drive attached to this VM.

Where too from here?

I'm actually doing this now myself, give me a sec.

@DustinB3403 pvcreate /dev/xvdb and proceed with vgextend…

@Francesco-Provino reading the manual for pvextend

You don't want to extend a pv tho, you want to create a new one. Add the new pv into the current vg (volume group), and then extend the lv (logical volume) to fill the new pv.

pvcreate /dev/xvdb
vgextend fedora /dev/xvdb
lvextend -l 100%FREE /dev/fedora/root

See if that lvextend works, might need to feed it another vg/pv path.

Thanks guys, I think I've got it.

@DustinB3403 Now you need to figure out why your root partition got filled up in the first place!
