Assignment of device names to external USB drives
Greetings, I am trying to set up a backup server, using a combination of internal and external (USB) disk drives. How can I manage the mapping of USB disk drives to device names? i.e. USB drives get assigned device names like da0, da1, da2... when they are detected. But if one of the drives fails or is not powered up, all other ones will get bumped down one in the list next time I reboot. The problem is that if I automatically mount /dev/da0a /archive/volume1, mount /dev/da1a /archive/volume2, etc. I run the risk of having the wrong disk being mounted on a mount point !?! Is there an obvious solution that I'm missing, or a canonical workaround to this problem?

Thanks Denis F. when you newfs a drive use the -L flag to give it a label like 'VOLUME1' then if you load the geom_label module that drive becomes availble under /dev/ufs/VOLUME1 -- The biggest problem with communication is the illusion that it has occurred.
