GlusterFS uses trusted storage pools and volume services across multiple nodes. Security depends on peer trust, network controls, and client auth strategy.
¶ Trusted Pool and Peer Security
- Add only verified nodes to the trusted storage pool.
- Restrict management ports to cluster members.
- Remove stale peers and rotated hosts promptly.
- Isolate replication and management traffic from public networks.
- Apply firewall policies allowing only client and peer subnets.
- Use dedicated storage VLANs where possible.
- Restrict mount access via network and export policy.
- Use Kerberos integration where environment supports it.
- Apply POSIX permissions and ACLs on mounted volumes.
¶ TLS and Data Protection
- Enable Gluster transport encryption in security-sensitive environments.
- Encrypt underlying storage where required.
- Protect snapshots/backups with strict ACLs.
¶ Monitoring and Recovery
- Monitor brick status and self-heal events.
- Alert on volume split-brain and repeated heal failures.
- Test failure and recovery runbooks periodically.
