Proxmox Storage Review Evidence
Date: 2026-06-20
Timezone: America/St_Johns
Supersession note: this is historical read-only storage evidence. It did not authorize cleanup. The 2026-06-21 production cutover used backup-only authority and no snapshot deletion or pruning.
Scope
Ran read-only Proxmox storage, LVM, snapshot, container, and VM inventory
checks across the visible HomeLab Proxmox nodes: Director, echo, and
forge.
This did not mutate production CT 121, sandbox CT 126, DNS, TLS, firewall,
routes, Proxmox cluster membership, storage allocation, snapshots, containers,
VMs, or device filesystems.
Cluster-Wide Summary
| Node | Address | Proxmox | Root Filesystem | Local Storage | Local-LVM | VG Free | Snapshot Signal |
|---|---|---|---|---|---|---|---|
Director |
10.0.0.250 |
pve-manager/9.1.4 |
18% used, 74 GiB available | 16.97% used | 28.87% used | 16.00 GiB | 7 CT snapshot LVs observed. |
forge |
10.0.0.248 |
pve-manager/9.0.3 |
49% used, 46 GiB available | 46.25% used | 63.10% used | 16.00 GiB | No CT snapshots listed; CT 103 large disk is 98.46% used. |
echo |
10.0.0.249 |
pve-manager/9.0.3 |
89% used, 11 GiB available | 83.92% used | 0.00% used | 0.00 GiB | No CTs, no VMs listed; local root storage is tight. |
No QEMU VMs were listed on Director, echo, or forge.
Director Snapshot Inventory
Director hosts the UAI Explorer production and sandbox containers. Its thin
pool is not close to full by data or metadata percentage, but VG free space is
limited and snapshot lineage exists.
Observed snapshot LVs:
| CT | Snapshot | Note |

High-use CT disk noted:
- CT
124(cortex-sandbox-vnext) root disk is 16 GiB with 81.30% thin data usage.
Forge Storage Notes
forge hosts CTs 103, 105, and 108.
| CT | Hostname | Disk Signal |
|---|---|---|
103 |
engineering |
Rootfs is 170G; thin data usage was 98.46%. It also has host mounts /mnt/skip_data and /mnt/toshiba. |
105 |
wow-weekend |
Rootfs is 120G; thin data usage was 25.07%. |
108 |
satisfactory |
Rootfs is 80G; thin data usage was 14.21%. |
forge local-lvm is 63.10% used. This is not an immediate full-pool condition,
but CT 103 should be treated as a targeted cleanup/review candidate before
adding more storage-heavy workloads.
Echo Storage Notes
echo had no CTs and no QEMU VMs listed by the read-only checks. Its
local-lvm thin pool showed 0.00% used, but VG free space showed 0.00 GiB and
the root filesystem was 89% used with 11 GiB available. /var/lib/vz/template
used about 7.4 GiB.
This makes echo a host maintenance candidate before assuming it has easy
headroom for staging, backups, templates, or incoming workloads.
Interpretation
The prior vague storage warning is now a specific maintenance decision:
- Do not create more rollback snapshots for UAI Explorer until an operator decides which existing snapshots must remain.
- Do not delete snapshots from UAI Explorer automation; the archived CT descriptions explicitly say to preserve and review.
- Before snapshot-heavy work, review CT
126snapshot retention, archived CTs115/116/117, CT253pre-gpu-move,forgeCT103, andechoroot/local template usage. - Production CT
121remains untouched and does not currently have snapshots listed in this evidence pass.
Result
The storage blocker is narrowed but not cleared. Read-only review is complete; operator-approved maintenance policy is still required before cleanup, snapshot deletion, backup pruning, workload migration, or snapshot-heavy UAI Explorer work.
