  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,
