FAQ
Rockstor runs on 64-bit commodity hardware, both x86_64 and ARM64 (e.g., Pi4). It can be installed on bare metal or a hypervisor. For home or small business use, HP, DELL, and Supermicro servers and desktops are recommended.
Yes, Rockstor can run from a USB flash drive, but it is optimized for less writes on non-rotational media. USB 3.0 devices are recommended for better performance, even if your motherboard doesn't support USB 3.0.
Rockstor is free to install using the x86_64 and ARM64 installers, which include the last stable version or recent release candidates. Access to the curated Stable channel updates requires a non-profit subscription fee, while the Edge and Testing channels are free.
Rockstor supports popular file sharing protocols like Samba/CIFS, NFS, and SFTP. It also supports apps like OwnCloud, Nextcloud, Syncthing, and Seafile through Rock-ons (Docker Plugins) for advanced file sharing.
Rockstor can be updated directly from the Web-UI when an update is available. You must select an Update Channel (Edge, Testing, or Stable) to receive 'rockstor' package updates. All upstream OS updates are offered by default.
Yes, Rockstor has a built-in engine that supports Docker-based applications called Rock-ons (Docker Plugins). These plugins provide additional functionality and can be found in the list of Available Rock-ons.
BTRFS is a newer filesystem under heavy development, and its stability has improved significantly. However, btrfs-raid5 and btrfs-raid6 profiles are not recommended for production use due to stability concerns. Rockstor confines users from using BTRFS freely, reducing the chances of hitting deep bugs.
Rockstor provides measures to prevent data loss, such as disaster recovery strategies and best practices. However, btrfs-raid5/6 profiles are not currently recommended for production use. For more details, see the Data loss - prevention and recovery in Rockstor documentation.
