IIRC, the recommended way on Mac OSX is to use a partition, and to
create it using diskutil. That way one meets the expectations of Mac
OSX' disk management. One _can_ go the full disk path, but it is not
the default method for MacZFS-74.x
In any case, I doubt that using whole disk access will help.
@
m...@saudette.net :
Can you check if there is anything MacZFS related in
/var/log/kernel.log or /var/log/system.log around your attempt
to create the raidz2? You may need to try "syslog -k Sender kernel |
grep -5 -e zfs -e ZFS" if no /var/log/kernel.log exist on your system.
