Container Mount Analysis - Storage Mapping to Proxmox ZPools¶

[!abstract] Overview This document maps every container volume mount configured in the Docker Swarm stack files to its underlying physical storage, identifying whether mounts are on local disk or NFS, and which Proxmox zpool stores that disk.

Summary Statistics¶

Total Mounts by Storage Type¶

Storage Type	Count	Description
Local (ssdpool)	~110	Config files, databases, app data
NFS	~35	Media, photos, documents
Named Volumes	~12	Docker-managed persistent storage
Socket Mounts	~8	Docker daemon access
System Mounts	~15	/proc, /sys, /rootfs (monitoring)
tmpfs	~3	RAM-based transcoding

Storage by Proxmox ZPool¶

ZPool	Location	Size	Used For
ssdpool (proxmox-1)	2x1TB SSD mirror	1.81TB	VM 201-205 root disks, all local mounts
ssdpool (proxmox-2)	960GB SSD	888GB	Non-Docker VMs
zfs3 (proxmox-1)	4TB+4TB stripe	7.25TB	VM data disks (scsi1), databases
zfs3 (proxmox-2)	4TB+4TB stripe	7.25TB	Additional storage
OMV disks (proxmox-1)	VM 106 disks	~3.5TB	All NFS exports

Key Findings¶

[!success] Configuration Patterns 1. All container configs (/homenet_config/*) are stored on ssdpool (SSD-backed) for performance 2. Databases (MariaDB, PostgreSQL, InfluxDB) are on local ssdpool or zfs3 for latency 3. Media files are on NFS from OMV server for centralized access 4. Camera footage is on dedicated NFS mount with 69GB capacity 5. Personal data (photos, documents) is on separate NFS mount for backup isolation

[!warning] Architecture Note All Docker VMs run on proxmox-1 (100.1.100.10). The OMV NFS server is also VM 106 on proxmox-1.
