FreeNAS 8 is an open source network attached storage solution based on FreeBSD and using the ZFS filesystem. It provides enterprise features like snapshots, replication, and integration with LDAP/Active Directory. Planned features include a plugin architecture and migration tools. The presentation demonstrated the configuration workflow and encouraged participation in the FreeNAS community.

- 1. FreeNAS 8: Open Source Storage for the Enterprise Dru Lavigne Director of Community Development, iXsystems FSOSS, October 28, 2011
- 2. Outline Introduction to FreeNAS 8 Current Features and ZFS Overview Planned Features Configuration Workflow with Demo Getting Involved with the Community Additional Resources
- 3. Introduction Open source NAS (network attached storage) based on an embedded version of FreeBSD (nanoBSD) and released under 2-clause BSD license Enterprise-grade appliance (TrueNAS) is also available in 2U/4U form factors with professional support
- 4. Introduction 8.x is a rewrite of the original monolithic design (.7x) to a modular design 8.0 was released May/11 with a focus on NAS core functionality 8.0.2 was released Oct/11 and incorporates most core features and many bug fixes 8.1, due late 2011 or early 2012, will introduce plug-in architecture for addons
- 5. Introduction If you're used to .7x: Hardware requirements have changed Designed to be installed on a thumb drive or compact flash, not a hard drive Graphical administrative interface is completely different and info in .7x forums/docs won't apply Many .7x features are not “core NAS” and may be missing until plug-in architecture is available
- 6. Current Features Create UFS or ZFS volumes (ZFS preferred) Import existing UFS/ZFS RAID volumes Import existing UFS, DOS, NTFS, EXT2/3 volumes Create shares using Appletalk, NFS, and SMB protocols Configure access through FTP/SFTP, SSH, and iSCSI
- 7. Current Features Integration with OpenLDAP, Active Directory Automated secure replication via rsync/ssh Automated ZFS snapshots Front-end to cron Reporting graphs, scheduled S.M.A.R.T. tests, automated alerts, UPS
- 8. Current Features Link aggregation and failover IEEE 802.1q VLAN support DDNS, SNMP, and TFTP support Control panel to stop/start and view the status of services Users Guide available in wiki, HTML, PDF, epub, and Kindle formats
- 9. Current Features Supports OSX Time Machine Supports Windows Shadow Copies Provides front-end to create ZFS clones, create ZFS datasets (quotas, compression), create zvols, export ZFS volumes, scrub ZFS volumes, and view zpool status
- 10. ZFS 128-bit filesystem designed to be a “self-healing” and to address hardware RAID issues with data integrity Snapshots only store what has changed since last snapshot Snapshots (which are ro) can be cloned (which are rw) Can rollback system to a snapshot
- 11. ZFS Uses ZIL (ZFS Intent Log) to manage writes. SSD ½ size of RAM can increase performance. Mirrored ZIL provides protection from data loss. Uses L2ARC on-disk cache. Dedicated SSD may accelerate read operations, especially when some data is read repeatedly, and cannot fit in the system memory ARC cache. Loss of device will only slow down reads (no data loss). http://www.solarisinternals.com/wiki/index.php/ ZFS_Best_Practices_Guide
- 12. ZFS RAIDZ1: equivalent to RAID5 without the write- hole RAIDZ2: double-parity solution similar to RAID6 RAIDZ3: triple-parity solution Caveats: resilvering takes time and can stress disks
- 13. ZFS Versions: 15: FreeNAS 8.0.2 28: FreeBSD 9.0, TrueNAS adds RAIDZ3, deduplication 30: Oracle has not open sourced (yet?) adds encryption FreeBSD zfsd (ZFS fault monitoring and management daemon) may address this
- 14. Planned Features for 8.1 Plug-in architecture for non-core functionality Document API so users can contribute own plug- ins Integrate plug-in architecture with PBI format Migration utility from .7 to 8.x Front-end to sysctl and loader tunables
- 15. Configuration Workflow 1. Set the administrative username and password 2. Create volumes/datasets 3. Create users/groups or integrate with LDAP/AD 4. Configure share and volume permissions 5. Start applicable service(s) 6. Test the configuration
- 16. Demo
- 17. Participate Report bugs Try out the testing snapshots Contribute configuration scenarios Assist users on the forums or IRC Blog or write a review about your FreeNAS experience
