Procedurex86: How to Initiate a Fast Reboot of a Directly Mounted Root Disk or Root Dataset

You can use Fast Reboot to directly mount a root (/) disk or root dataset, then reboot to it:

  1. Become superuser or assume an equivalent role.

  2. Mount the root (/) disk.

    For example:

    # mount /dev/dsk/c1d0s0 /mnt
    • To mount a root dataset, type:

      # zfs mount rpool/dataset
  3. Reboot the mounted disk or mounted dataset.

    For example:

    # reboot -f -- '/mnt/platform/i86pc/kernel/amd64/unix'
