HDD Is Recognized but Not Usable

[Kaiware]

Hello. I recently installed Proxmox on a new machine. The device is equipped with a 256GB SSD and a 4TB HDD, and I’ve confirmed that it’s detected in Proxmox. However, when I check Node > Summary, the HD Space shows only 67GB, which I assume is just the SSD being used. Do you know what might be causing this? Thank you.

This is how a LVM setup works. The OS volume and guest volume are sized automatically by the installer and separate. Check lvs. Use ZFS if you want to use all the space. You can also delete the data volume and extend the root one on the OS disk or install with proper settings.
