Safe ?

Big 3ware sata raid with 16 disks. First two disks are a mirror to boot off of. I installed the system with sysinstall and created all the partitions on the boot mirror, etc., and just didn't even touch the 14-disk array that was also created. So then I spent hours researching bsdlabel and gpt and blah blah blah, and I just got fed up and: dd if=/dev/zero of=/dev/da1 bs=1k count=1 newfs -m 0 /dev/da1 mount /dev/da1 /mnt And that's that. But it seems too good to be true! Can someone please comment on this scheme and if there are some hidden dangers or lack of functionality that I will regret in the future ? Will it fsck just like any other UFS2 partition I run ? Can I run quotas and snapshots and everything else on it, just like normal ? Other than the fact that I can't boot this, is there _any downside whatsoever_ to newfs'ing raw disk like this ? --------------------------------- Don't pick lemons.
