One comment (and it's not a flame!) - honestly... ;-) With an array of that size, on a machine that important - did you not test to see what would happen with a failed drive? The only system we have running with RAID at the moment is an NT box on an HP Netserver - but even with that, we pulled a drive to 'see what happened' - and a) make sure it works, and b) note down any important steps to recovering it... We did this before we certified the machines as 24/7 & 'mission critical' (It also shows that even with NT & 'expensive' hardware, theres always stuff they leave out the manual, or have changed on screen, but not in the manual ;-) Regards, Karl Pielorz To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
