About a year ago I followed default installation of Proxmox and then make a Nextcloud server directly on it so I can use the IP address. However, I want to install host Nextcloud to another VM, then use reverse Proxy to allow everyone on my LAN to access to it. But my pve-root got nearly full, check with lsblk like on the picture I show below I found that when install Proxmox, it only set pve-root about 24.5 Gb on my 64Gb USB, the rest go to 2 pve-data. If I deleted those, does the system be affected? And is there any way to reduce the size of both 2 pve-data and give it to pve-root?
