      I did a fresh install then turned the machine off and removed on
    disk. It booted again just fine. Then I turned it off again and
    inserted the disk I had removed. Now it will panic:

      panic: softdep_setup_inomapdep: found inode
      cpuid = 0
      boot() called on cpu#0
      Uptime: 2s

      If I removed the disk and boot again it will work and show the
    following message:

      ar0: 152627MB <ATA RAID1 array> [19457/255/63] status: DEGRADED
    subdisks:
      disk0 READY on ad4 at ata2-master
      disk1 DOWN no device found for this disk

      How can I replace a failed disk with this setup ? Given what I've
    read I'm not really using the controller's RAID support but only the
    RAID support present in the ata subsystem. Is that true ? In the BIOS
    I don't have any arrays.

    Thank you,
