I am running 11.0-CURRENT (r260850) with zfs on root with MBR. After upgrading my 10.0-RELEASE (r260669) system to 11.0-CURRENT (r260850) my zpools reported that they needed to be upgraded. So, I upgraded my zpools and I am attempting to update the bootcode (as required). I managed to get the boot1 stage code updated, but cannot get the boot2 stage code updated. Here is what I have done: # sysctl kern.geom.debugflags=0x10 kern.geom.debugflags: 0 -> 16 # dd if=/boot/zfsboot of=/tmp/zfsboot1 count=1 1+0 records in 1+0 records out 512 bytes transferred in 0.014996 secs (34142 bytes/sec) # gpart bootcode -b /tmp/zfsboot1 /dev/ada0s1 bootcode written to ada0s1 # dd if=/boot/zfsboot of=/dev/ada0s1a skip=1 seek=1024 dd: /dev/ada0s1a: Operation not permitted The final dd statement fails with "operation not permitted". In all my research, understood the initial sysctl command I ran would prevent this particular error from happening. What do I need to do to get the boot2 code written to /dev/ada0s1a? Thanks. -Tom
