AFAIK (and this had better be the case, we're using enough of them!) - RAID / CCD etc. will merge multiple 'physical' drives into a number of typically larger 'logical' drives, the file systems are created on the Logical drives, thus in our case 5 * 4.5Gb physical drives are merged into one 22.5Gb 'logical' drive, which is then created as one filesystem = 22Gb's of space (spanning all 5 drives)... If your into RAID have look at Vinum (it's part of 3.0-RELEASE onwards) (man vinum) Regards, Karl To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
