Virium

Viriumd is a lightweight storage API built on top of LVM (Logical Volume Manager) and iSCSI (Internet Small Computer Systems Interface) using targetcli-fb.

⚠️ Virium is not a scalable or highly available storage solution by default. It is designed for homelab, testing, or demo environments.

That said, a somewhat highly available setup could be achieved using tools like Linbit DRBD for replication and keepalived with VRRP for virtual IP failover.

✨ Motivation & Goals

I created Virium because I found most Kubernetes external storage drivers too complex or oddly implemented for my homelab needs. I wanted:

• A simple solution
• Built on solid, well-known tools (LVM + iSCSI via targetcli-fb)
• An opportunity to learn and practice Golang from scratch

This project is not production-ready and is not intended to be, at least in its early stages.

🔧 Features (current or planned)

• REST API for managing LVM volumes and exposing them via iSCSI
• CSI driver support for Kubernetes integration
• Snapshot support via LVM
• Simple YAML-based configuration
• Systemd + RPM packaging

🚫 Not Included (by design)

• High-availability or failover (though possible with DRBD + keepalived)
• Multi-node storage orchestration

🧪 Ideal Use Cases

• Homelabs
• Learning/experimentation
• Demo environments
• Lightweight Kubernetes clusters with external CSI driver

🚀 Requirements

Firewall:

• open TCP port 8787 (default customizable port)

Packages:

• lvm2
• targetcli
• target-restore
