My new machine has a 2TB M2… I let the installer automatically install. When I look at that disk I see 3 partitions: 629mb /Boot/efi, 1.1GB /boot, 2TB LVM not mounted no name — ??? – Is this an artifact of the Gnome Disk tool and not right? Is the os using the 2TB LVM and I just can’t see it – or is it really dead space (totally unused) and how do I claim it for use? – ---

This is a common problem with the default installer. Unless you select a meaningful size for /home it will extend to the end of the disk. Best option is wipe the whole thing and start again. ---

Yes. The installer default is to create LVM volumes (except /boot and /boot/efi) and use XFS filesystem. LVM is great. XFS … cannot be shrunk. Better to adjust in installer. One could create `/home/mariadb/` and bind-mount it to `/var/lib/mysql` (or whatever) but then there are SELinux contexts to tackle. ---

I helped someone through a custom partition set up a while ago: [Installing a Rocky 8.4 Virtual Box VM as a qcow2 Openstack Image - #10 by iwalker](https://forums.rockylinux.org/t/installing-a-rocky-8-4-virtual-box-vm-as-a-qcow2-openstack-image/5196/10) That post has screenshots taking you through the GUI installer process step-by-step of setting up your partitions. Whilst this example was for a custom setup with a single partition, it’s easy enough for you to see and adapt it, creating partitions for /, /usr, /var or whatever other ones you need. You can even adapt it further using LVM instead of standard partitions - you’ll see how to do that once you get into the custom partition setup anyway. ---
