Hello, after messing around with atacontrol software RAID a bit I became quite confident that this can't be any worse than the el cheapo IDE RAID (Highpoint, Promise, CMD) that we commonly use around here and figured I could as well ditch the controllers and use the PCI slots for something else. But now I stumbled about the last remaining machine that doesn't have any RAID at all and am wondering how I go about initializing the array. Basically, I can create one with atacontrol create and then use dd to copy over the data from the primary to the secondary disk but I don't know what's going to happen if I do this in multi user (as taking down a production webserver for ~40 minutes to do it in single user isn't really a viable option). Will dd just copy over all the data from drive 1 and any writes during that time (which surely will happen, you gotta have access_log after all) will get mirrored to both disk by atacontrol so that I end up with a perfectly synced pair of disks once dd is over? Any comments would be greatly appreciated. TIA & regards, Gabriel To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
