ZFS Boot

What is ZFS Boot?

The team is working to provide the ability to boot the Solaris Operating System from a ZFS root filesystem as well as install the Solaris Operating System to a ZFS filesystem.

The ZFS Boot project has been divided into three pieces: x86 boot, sparc boot, and install. The x86 boot is available in snv_62. Setup instructions can be found in the Documentation sections. Sparc boot and Install work are still in progress.

This ZFS Boot project will enable booting Solaris systems from root file systems of type ZFS. The main pieces of work are:

• A ZFS plug-in for the GRUB boot loader (available in snv_62)
• Development of a boot loader usable on SPARC that can read files from a zfs file system.
• Some ZFS enhancements necessary for acting as a root file systems
• Enhancements to Solaris Install and Liveupgrade in order to set up and maintain root file systems in ZFS pools.
