Hi list,

  I'he a backup server with a 1 TB partition builded using geom_stripe with
4 200gb ide drives and 4 73gb scsi drives. This server is running FreeBSD
6.1-STABLE, the backup data is received via FTP and NFS.

 The geom_stripe configuration is the following:

 At some moments the machines just reboot and today, after configure the
machine to do remote log I obtained the error messages before reboot.

 These are the messages:

 Any idea on how can I know what disk is causing the problem ??
