Transcript

  • 1. Introducing FreeNAS 9.1.0 Dru Lavigne Documentation Lead, iXsystems FOSSCON, August 10, 2013
  • 2. Outline Introduction to FreeNAS Core Features ZFS Overview What's New in 9.1 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 tiered professional support
  • 4. Releases 8.0 was released in May, 2011 with a focus on NAS core functionality (redesign of .7x which was EOL'd in 2011) 8.2.0 introduced the original Plugins architecture for installing additional software (July 20, 2012) 8.3.0 introduced ZFSv28 (October 26, 2012) 8.3.1 introduced full disk encryption (March 20, 2013) 9.1.0 is latest release (August 1, 2013)
  • 5. Core Features Create UFS or ZFS volumes (ZFS recommended) Import existing UFS/ZFS RAID/z 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
  • 6. Core Features Integration with OpenLDAP, Active Directory Automated, secure replication via rsync/ssh Automated ZFS snapshots and scrubs Front-ends to cron, sysctls, loader.conf Reporting graphs, scheduled S.M.A.R.T. tests, automated alerts, UPS
  • 7. Core Features Link aggregation, failover, and VLAN support DDNS, SNMP, and TFTP support Control panel to stop/start and view the status of services Supports OSX Time Machine and Windows Shadow Copies
  • 8. Core Features OS is installed on USB stick/CF and is separate from data on storage disks Upgrades keep a backup of the old OS, allowing for rollback Administrative GUI accessed through a web browser; 8.2 added a web shell for command line operations PDF of Users Guide published with each software release
  • 9. ZFS 128-bit filesystem designed to be “self-healing” with checksums to provide data integrity Snapshots (point in time) only store what has changed since the last snapshot (COW) Scheduled scrubs verify integrity of disks and data Deduplication saves space (removes duplicate data) Datasets have properties (quotas, compression)
  • 10. ZFS RAIDZ* levels designed to overcome hardware RAID limitations RAIDZ1: equivalent to RAID5 RAIDZ2: double-parity solution similar to RAID6 RAIDZ3: triple-parity solution Caveats: resilvering takes time and can stress disks
  • 11. What's New in 9.1.0 Based on 9.1-STABLE: Latest drivers and bug fixes Adds newest ZFS feature flags, including LZ4 compression Same ABI (Application Binary Interface) as PC- BSD PBIs (over 1100) means that there is more software available for installation
  • 12. What's New in 9.1.0 Volume Manager: UFS and ZFS now have separate managers How to extend a ZFS pool or add log/cache devices is more intuitive Easier to manage a large amount of disks Estimated size of ZFS pool is displayed for selected RAIDZ* layout and GUI will not let you create an unsupported layout
  • 13. ZFS Volume Manager
  • 14. Plugins Easier to Use Users no longer have to first configure a jail as the Plugins mechanism automaticaly creates and uses a default jail New integrated AppCafe browser lists available FreeNAS PBIs, simply highlight the app and click its Install button Appcafe.org (launching soon) will make it easy to find PC-BSD, pfSense, and FreeNAS PBIs
  • 15. Plugins Easier to Use
  • 16. Jails for Advanced Users Users who want more control over software installations now have a choice of what type and how many jails to create and can install software using FreeNAS PBIs, PC-BSD PBIs, FreeBSD pkgng packages, or FreeBSD ports The only required parameter when creating a jail is the name, however users can choose to configure other items such as the IPv4 and/or IPv6 address(es), MAC address, and whether or not to use vimage
  • 17. Jails for Advanced Users
  • 18. Jails for Advanced Users
  • 19. What's New in 9.1.0 GUI now available over IPv6 and can specify alternate port
  • 20. What's New in 9.1.0 Shell now supports paste and resizing
  • 21. What's New in 9.1.0 Alerts can now be dismissed
  • 22. What's New in 9.1.0 Init/Shutdown Scripts
  • 23. What's New in 9.1.0 Can now configure replication user
  • 24. What's New in 9.1.0 Can now change SFTP logging level/facility
  • 25. What's New in 9.1.0 Can now change SFTP logging level/facility
  • 26. What's New in 9.1.0 Ability to boot into a debug kernel
  • 27. What's New in 9.1.0 Directory Services menu added
  • 28. What's New in 9.1.0 zilstat utility added for testing dedicated ZIL: http://www.richardelling.com/Home/scripts-and- programs-1/zilstat Easy-RSA has been added to the base, making it easier to create and manage RSA keys for use with OpenVPN
