FreeNAS 9.1.1 Upgrade

November 7, 2013 kobaan Leave a comment

Today I upgraded my FreeNAS storage from 8.3.1 to 9.1.1 with all RAIDZ pools still alive, all new ZFS features available, no problems so far.

Further I printed lots of 90 degree makerbeam brackets, and uploaded all my design files to Thingiverse.

Recompiling Cubieboard kernel to get ACM support

I had to recompile the kernel on the cubieboard again, to enable USB CDC ACM support to be able to migrate the dynamixel servos over from the arduino to a dedicated USB2AX controller.

CONFIG_USB_ACM=m
