           Summary: Installer Auto (ZFS) Partitioning creates unbootable
                    system if more than 10 drives with RAIDZ2
           Product: Base System

Please also see another bug which may be related (219001)

When using the installer and the Auto (ZFS) partitioning option and selecting
more than 10 drives and the RAIDZ2 option (possibly others too), the resulting
system installs fine but does not boot. The following error is given:

zfs I/O error - all block copies unavailable

Building a system with 10 or less drives works fine. Building a system with 11
or more drives fails to boot. 

Tested on VMware ESXi-5.5.0  AMD64.  2 Processors, 32GB memory. Dual LSI Logic
SAS SCSI controllers.
