Fedora Block Device Full How - Extend Partition

[Francesco Provino]

Of course, you can incrementally add multiple virtual disks to the VM, adding it as PV to your VG etc…

@Francesco-Provino OK give me a moment, working to create the block device.

[travisdh1]

@DustinB3403

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

I don't know the command to expand an ext4 file system off the top of my head

[DustinB3403]

@travisdh1

[stacksofplates]

Is /dev/xvda2 mounted somewhere?

[travisdh1]

@DustinB3403 If you're sure that /dev/xvda2 is not being used by something else, try the pvcreate with -ff. It should force the command to complete.

His root is XFS, so xfs_grows should do the trick.

[DustinB3403]

The system is saying that xvda2 is mounted.

Yet I have no idea how it's mounted.

df -h

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

[stacksofplates]

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.

[DustinB3403]

@stacksofplates

[stacksofplates]

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.

[DustinB3403]

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.

[DustinB3403]

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