In this section, da1 is conformed to a broken disk. # gpart destroy -F da1 da1 destroyed # gpart create -s gpt /dev/da1 da1 created # gpart add -s 64K -b 34 -t freebsd-boot -l /boot/boot0 /dev/da1 da1p1 added # gpart add -s 1G -t freebsd-swap -l swap0 /dev/da1 da1p2 added # gpart add -t freebsd-zfs -l disk0 /dev/da1 da1p3 added # gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 /dev/da1 bootcode written to da1 Create zpool for rootFS I named a new zpool rpool2....

I installed FreeBSD 10.0 on my ConoHa VPS. Fortunately, ConoHa prepared a FreeBSD 10.0 image to make installation easy. In this installation, I enabled virtio and Root-on-ZFS. ConoHa allows us to use virtio by default. Automatic Root-on-ZFS is one of the features of FreeBSD 10.0. Before 10.0, we had troubles in setting Root-on-ZFS. Now, several results for commands/experiments are shown below. Benchmark for virtio Notice: there is no result when...
