What openmediavault is
openmediavault is a free Debian Linux system for network-attached storage, designed mainly for small and home offices. Its web-based administration is intended to help users install and manage a NAS without deeper technical knowledge. File services include SSH, NFS, SMB/CIFS, and RSync. Storage features include software RAID, per-volume quotas, access control lists, and shared-folder snapshots on Btrfs file systems. Monitoring options include syslog, watchdog, S.M.A.R.T., read-only SNMP v1/2c/3, email notifications, and checks of process and system state. Networking includes link aggregation, Wake On LAN, and IPv6. Plugins can add TOTP two-factor authentication, antivirus, USB backup, Microsoft OneDrive synchronization, and Kubernetes based on K3s. The Kubernetes plugin is required to use the app catalog for containerized or Dockerized applications. Installation instructions cover existing Debian 13 systems and AMD64 (x86-64) bare-metal hardware; updates use Debian package management. The project is distributed under GNU GPL v3 and is provided without warranty.
