I thought anything under /dev/mapper/ is using LVM?

Ya looks like / is using LVM. You would have to shrink your /home a bit and then grow your / volume.

[stacksofplates]

How did you install this? Every time I’ve installed it / gets 50GB and /home takes the rest.

Oh this is a desktop. If this was a server I'd ask what it's doing and check for lots of or large log files.

It's probably full of just regular software packages.

Shrink /home by 50G and give it to root. On a workstation it doesn't make sense to give root 10G. I don't know why tha'ts default. I thought the default was 15 GiB? But still, it's a workstation, installing software will go to root and fill that shit up fast.

It's LVM right? If so it's easy to fix.

Here's mine:

According to above, had mine only been 10G i'd be out of room too.

I could have sworn it's 15 GiB by default on Fedora Workstation... which is still too low on a desktop.

You can do it in Cockpit so easily:

/home: shrink it

Then add it to your / partition

I do not recall changing this. I would assume that I click custom and then let it create it in the advanced screen.

I agree with you and @Tim_G that this seems odd form my normal experiences.

I cannot unmount /home because it is busy. even after a reboot and not logging in.

You will have to use a live bootable OS to unmount /home.

Why can't you do it live in Cockpit?

I never had to unmount.

[JaredBusch]

For the record, my laptop is setup this way.

@jaredbusch that likely means that you have a shell session that is currently "cd'd" into the /home somewhere and/or some process that is running out of it.

[Obsolesce]

What filesystem?

/home

/home

As in XFS, ext4

Both /home and / are ext4.

It has to be some process then, because it gives this right after a reboot

[scottalanmiller]

Try this...

ps aux | grep /home

ps aux | grep /home

System is not logged in. Doing it from the cockpit terminal resulted in this

[Obsolesce]

1. Unount /home
   umount /home

2. Shrink the /home filesystem
   fsck -f /dev/mapper/fedora-home
resize2fs /dev/mapper/fedora-home 190G

3. Shrink the /home logical volume
   lvreduce -L -24G /dev/mapper/fedora-home

4. Resize the /home partition to the size of the LV
   resize2fs /dev/mapper/fedora-home

5. Extend the /root logical volume
   lvextend -L +24G /dev/mapper/fedora-root

6. Extend the /root filesystem
   fsck -f /dev/mapper/fedora-root
resize2fs /dev/mapper/fedora-root

7. Mount /home
   mount /home
