LVM Thin Storage Enabled on pve

Last Updated: 2026-01-31
Document Version: 1.0
Status: Active Documentation


Date: $(date)
Status: LVM Thin Storage Configured

Summary

LVM thin storage has been successfully enabled on pve node for migrations.

Configuration

Volume Group

  • Name: pve
  • Physical Volumes: 2 disks (sdc, sdd)
  • Total Size: ~465.77GB
  • Free Space: ~257.77GB

Thin Pool

  • Name: thin1
  • Volume Group: pve
  • Size: 208GB
  • Type: LVM thin pool
  • Status: Created and configured

Proxmox Storage

  • Name: thin1
  • Type: lvmthin
  • Configuration:
    • Thin pool: thin1
    • Volume group: pve
    • Content: images,rootdir
    • Nodes: pve

Storage Status

pve storage:
- local:     active (directory storage)
- thin1:     configured (LVM thin storage)
- local-lvm: disabled (configured for ml110 only)

Usage

Migrate VMs to pve with thin1 storage

# From source node (e.g., ml110)
ssh root@192.168.11.10

# Migrate with thin1 storage
pct migrate <VMID> pve --storage thin1

# Or using API
pvesh create /nodes/ml110/lxc/<VMID>/migrate --target pve --storage thin1 --online 0

Create new VMs on pve

When creating new containers on pve, you can now use:

  • thin1 - LVM thin storage (recommended for performance)
  • local - Directory storage (slower but works)

Storage Capacity

  • thin1: 208GB total (available for VMs)
  • local: 564GB total, 2.9GB used, 561GB available

Verification

Check storage status

ssh root@192.168.11.11 "pvesm status"

Check volume groups

ssh root@192.168.11.11 "vgs"

Check thin pools

ssh root@192.168.11.11 "lvs pve"

List storage contents

ssh root@192.168.11.11 "pvesm list thin1"

Notes

  • The thin pool is created and ready for use
  • Storage may show as "inactive" in pvesm status until first use - this is normal
  • The storage is properly configured and will activate when used
  • Both thin1 (LVM thin) and local (directory) storage are available on pve
