1. Run Post-Installation Script

The community post-install script is used to simplify initial setup, disable subscription warnings, and configure repositories.

2. Delete local-lvm and Expand Root

This sequence assumes your VM disks are already migrated and the local-lvm storage is removed. The goal is to reclaim the block storage space and merge it into the directory-based / partition.

A. GUI Preparation

Go to the Proxmox GUI at Datacenter $\rightarrow$ Storage:

  • Edit local (Directory): Select the local storage entry. Click Edit. Under the Content dropdown, ensure Container template and Disk image are both selected (or checked). This allows the reclaimed space to host container/VM files.
  • Remove local-lvm: Select the local-lvm entry. Click Remove. This prepares the underlying LVM thin pool for deletion.

B. Shell Commands

Execute these commands carefully in the Proxmox Shell:

# 1. REMOVE the LVM Thin Pool (named 'data' by default)
# !!! WARNING: DELETES ALL VM DATA ON local-lvm !!!
lvremove /dev/pve/data

# 2. EXTEND the root volume to use all the freed space
lvextend -l +100%FREE /dev/pve/root

# 3. RESIZE the filesystem to recognize the new space
resize2fs /dev/mapper/pve-root
