Storage Reference¶

This document covers all storage systems in the Proxmox cluster.

Overview¶

Storage	Type	Host	Path	Capacity	Purpose
local-lvm	LVM-thin	All nodes	-	Varies	VM boot disks
px3-nas	NFS/SMB	px3	/mnt/nas-storage	1.8 TB	Shared file storage
pikvm-backup	NFS	pikvm	/mnt/external	2.7 TB	Legacy offsite backups
pbs-fr	PBS	CT 5101	10.35.1.101	~1.1 TB	Primary off-site (incremental)

px3-nas (Local NAS)¶

A 1.8TB local disk on px3 shared via NFS and SMB to the cluster.

Hardware¶

Host: px3 (REDACTED_IP)

⚠️ Temporary Setup (since 2026-02-07)¶

The NAS drive (WDC WD20EADS) was removed due to Ceph I/O contention. NAS is temporarily served from a USB drive (sdd) while a Samsung 870 EVO 2TB SSD replacement ships. Performance: ~72 MB/s (USB 3.0). See px3 Hardware for details.

Hardware¶

Host: px3 (10.44.1.30)
Disk: /dev/sdd2 (ext4, temporary USB — SSD replacement on order)
Mount point: /mnt/nas-storage
Capacity: 1.8 TB

Access Methods¶

NFS (Proxmox Storage)¶

The NAS is registered as Proxmox storage px3-nas for VM images, ISOs, backups, and templates.

# Check status
pvesm status | grep px3-nas

# Mount point on nodes
ls /mnt/pve/px3-nas/

Proxmox storage.cfg entry:

nfs: px3-nas
    server REDACTED_IP
    export /mnt/nas-storage
    content images,iso,backup,vztmpl
    options vers=4

SMB (Windows/Client Access)¶

For Windows VMs and workstations, connect via SMB:

Setting	Value
Share path	`\\REDACTED_IP\storage`
Username	`nasuser`
Password	`REDACTED_PASSWORD`

Windows command:

net use Z: \\REDACTED_IP\storage /user:nasuser REDACTED_PASSWORD

Guest Access

Guest access is configured but Windows 10/11 blocks insecure guest auth by default. Use the nasuser credentials or enable guest auth in Windows: ```powershell Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanWorkstation\Parameters" -Name "AllowInsecureGuestAuth" -Value 1

NFS (macOS)¶

macOS can mount NFS shares directly. Create a mount directory and mount the NFS export:

# Create mount point
mkdir -p ~/Storage/nas

# Mount NFS share
mount_nfs -o vers=3 REDACTED_IP:/mnt/nas-storage ~/Storage/nas

# Verify mount
mount | grep nas-storage

To unmount:

umount ~/Storage/nas

SMB (macOS)¶

For SMB access on macOS, use Finder or mount via command line:

Finder method: 1. Press Cmd + K to open "Connect to Server" 2. Enter: smb://nasuser@REDACTED_IP/storage 3. Click "Connect" 4. Enter password: REDACTED_PASSWORD

Command line method:

# Create mount point
mkdir -p ~/Storage/nas

# Mount SMB share
mount_smbfs -o soft nasuser@REDACTED_IP/storage ~/Storage/nas

# Verify mount
mount | grep storage

To unmount:

umount ~/Storage/nas

NFS vs SMB on macOS

NFS: Better performance for large file transfers, native support
SMB: Better compatibility with Windows, easier permissions handling Choose based on your workflow needs.

Server Configuration¶

NFS exports (/etc/exports on px3):

/mnt/nas-storage REDACTED_SUBNET(rw,sync,no_subtree_check,no_root_squash,insecure)
/mnt/nas-storage REDACTED_SUBNET(rw,sync,no_subtree_check,no_root_squash,insecure)

SMB config (/etc/samba/smb.conf on px3):

[storage]
   path = /mnt/nas-storage
   browseable = no
   read only = no
   guest ok = yes
   create mask = 0775
   directory mask = 0775
   force user = nobody
   force group = nogroup

Directory Structure¶

/mnt/nas-storage/
├── dump/          # Backup files
├── images/        # VM disk images (Proxmox)
├── snippets/      # Proxmox snippets
├── synced/        # User shared files
└── template/      # VM templates

Troubleshooting¶

Check NFS server status on px3:

ssh px3 'systemctl status nfs-server'
ssh px3 'exportfs -v'

Check SMB server status on px3:

ssh px3 'systemctl status smbd'
ssh px3 'smbstatus'

Test connectivity from another node:

showmount -e REDACTED_IP
smbclient -L //REDACTED_IP -U nasuser

pikvm-backup (Offsite)¶

Remote NFS storage on pikvm for offsite backups.

Setting	Value
Server	REDACTED_IP (pikvm)
Export	/mnt/external
Mount	/mnt/pve/pikvm-backup
Capacity	2.7 TB
Content	backup, vztmpl

Warning

This is offsite backup storage only. Do not use for primary VM storage.
