Proxmox Storage Management#

What Was Established#

SMB/CIFS shares can be integrated into Proxmox via CLI or the Web GUI.
GUI integration is recommended for Proxmox-native features (backups, ISOs, templates) and automatic retention management.
Local disk inspection (e.g., sda2) requires verifying mount status and filesystem type to avoid conflicts with active root partitions.

CLI Mounting (Persistent)#

Install utilities: apt update && apt install cifs-utils
Create credentials file: /etc/smb-credentials with chmod 600.
Add to /etc/fstab: //server/share /mnt/smb-share cifs credentials=/etc/smb-credentials,uid=0,gid=0,file_mode=0660,dir_mode=0770,iocharset=utf8 0 0
Test mount: mount -a

GUI Mounting (Proxmox Native)#

Navigate to Datacenter → Storage → Add → SMB/CIFS.
Required Fields: ID, Server, Share, Username, Password.
Content Types (select based on use case):
- ISO images
- Container templates
- VZDump backup files
Advanced Options: Max Backups, Prune Backups, SMB Version (e.g., 3.0), Domain.
Verification: Green checkmark in Storage list indicates active status. Use “Test Connection” if available.

Local Disk Inspection#

Check status: lsblk, blkid /dev/sda2, mount | grep sda2.
Mount temporarily: mount /dev/sda2 /mnt/sda2.
Inspect: ls -la /mnt/sda2, df -h, du -sh /mnt/sda2/*.
Note: sda2 is typically the root partition on Proxmox hosts; avoid modifying if already mounted at /.

Open Questions#

Specific purpose of sda2 on Isengard (192.168.1.69)? (Likely root, but verify with lsblk/blkid).
SMB share usage for LonelyMountain (192.168.1.137) backups vs ISOs? (GUI method preferred for VZDump retention).

TrueNAS (Vairë) - Storage & Backup Server

Mon, 27 Apr 2026 00:00:00 +0000

TrueNAS (Vairë) - Storage & Backup Server#

What Was Established#

TrueNAS (Vairë) is deployed as a Proxmox VM to serve as the primary storage and backup server for the homelab. It handles ZFS storage pools, NFS/SMB shares for Proxmox and other VMs, and hosts Collabora Office in an iocage jail.

Key Decisions#

VM Type: Q35 with UEFI firmware (recommended for ZFS stability).
Resources: 16 GiB RAM (fixed, no ballooning) and 2 vCPUs. 32 GB boot disk separate from storage.
Storage: 4TB HDD passed through directly to the VM for ZFS data integrity and performance.
Backup Integration: NFS share (/mnt/tank/backups) configured for Proxmox backups. SMB share available for manual access.
Collabora Office: Deployed in a dedicated iocage jail on port 9980.

Current Configuration#

Hostname: Vairë
IP Address: 192.168.1.100 (NFS) / 192.168.1.133 (SMB)
Proxmox VM ID: [Pending verification]
ZFS Pool: tank (4TB HDD passthrough)
NFS Share: /mnt/tank/backups (Network: 192.168.1.0/24, Maproot: root)
SMB Share: /mnt/tank/backups (Version 3.0)
Collabora Jail: iocage jail, port 9980

Historical Notes#

The conversation notes two different IPs for TrueNAS (192.168.1.100 and 192.168.1.133). Verify which IP is currently assigned to the TrueNAS VM.
TrueNAS CORE uses iocage jails. Ensure jail templates are up to date.
Proxmox backups to NFS require hard,intr,noatime mount options in /etc/fstab.

Open Questions#

Which IP address is currently active for Vairë (192.168.1.100 or 192.168.1.133)?
Is the 4TB HDD currently formatted as a ZFS pool on Vairë?
Has Collabora Office been integrated with a Nextcloud instance?

Proxmox ZFS Storage Setup

Proxmox ZFS Storage Setup#

What Was Established#

Procedures for initializing ZFS pools using multiple drives via the Proxmox Web GUI and configuring them as usable storage for Virtual Machines (VMs) and Linux Containers (LXC).

Key Decisions#

RAID Levels: Selection depends on the number of disks and redundancy requirements:
- Stripe (RAID 0): Maximum capacity, no redundancy.
- Mirror (RAID 1): Redundancy, 50% capacity loss.
- RAID-Z1/Z2: Requires 3+ disks for parity-based redundancy.
Compression: lz4 is the recommended compression algorithm for performance.
Ashift: Set to 12 for modern SSDs/NVMe to ensure proper block alignment.
Thin Provisioning: Enabled for storage pools to allow for flexible disk allocation.

Current Configuration#

1. Initialize ZFS Pools (Web GUI)#

Navigate to: Datacenter → Node → Disks → ZFS

Proxmox ZFS Storage & Installation Patterns

Sun, 23 Mar 2025 00:00:00 +0000

Proxmox ZFS Storage & Installation Patterns#

What Was Established#

Procedures for managing ZFS rpool on single-disk Proxmox installations, including methods for limiting pool size and troubleshooting import failures.

Key Decisions#

Single Disk Size Limitation: When installing Proxmox on a large disk but wanting to limit the ZFS pool to a specific size (e.g., 64GB) to leave room for other partitions, use the hdsize parameter in the Proxmox installer’s Advanced Options.
Custom Partitioning Method: For complex layouts, it is possible to manually partition a drive in Debian and then upgrade the system to Proxmox VE.

Current Configuration#

ZFS Pool Creation (Manual)#

To create a ZFS pool with specific optimizations (ashift=12, compression=lz4) and a size limit:
