The md pseudo-device does work as described in the handbook in section 10.6.2. However it doesn't seem to work when I try to use a device other than /dev/md0, specifically /dev/md1. Some other pseudo-devices can be specified in the kernel configuration with a number to indicate the number of units. This doesn't seem to work with md. For example: pseudo-device md 3 # Memory "disks" I have run MAKEDEV md0 MAKEDEV md1 MAKEDEV md2 but I still get the message dd: /dev/md1: Device not configured when I do dd if=afile of=/dev/md1 How do I use more than one md device at a time? -- Adam Mackler To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-stable" in the body of the message
