what make / model hard drives ? what kind of scsi controller ? 1520? 1540? 2940? > Alternatively if I put it on the SCSI bus how can I use it as a second HDD? jumper the second hard drive with a different SCSI id (should have a row of jumpers on the disk labeled A0,A1,A2 or E0,E1,E2 or somesuch - see the manuf web page ps: dont pick an id like 7 (all ones usually reserved for the controller)) take care how you set up the SCSI buss (I assume your card and current SCSI disk are correctly terminated - remove the termination /->on the new disk<-/ and place it between the existing disk and controller ps: adding SCSI is kindof like setting up a coax network in that you have to worry about the correct termination of cabling at both ends.

Why mirror the whole disk? - i've heard vinum is used here (I have yet to play with it) - ccd's (see ccdconfig) are working fine for me currently ( I have similar hardware with 1x1.5G IDE and 3x512M SCSI-2's on an Adaptec 2940 card - the SCSI's are setup with 3 swap partitions and some ccd's holding /var and /usr ) Hope this helps Regards Richard To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
