So I'm reading about ZFS on the FreeBSD ZFS quick-start guide, and I'm stuck at this part: when I attempt to use a device (/dev/da0), it throws an error and the device dissapears until I reboot. :\ Specifically, this:
I suspect the guide actually requires a physical Device to be plugged into a USB Port. However, until I can get a proper RAID set up, performing backups on-Disk is the only option I have... Any ideas guys?
I don't want to skip around on the guide, since I might miss something important.
Thanks for any help. 
zpool create example/ dev/da0
, and throws the error: cannot open '/dev/da0': No such file or directory
, which is strange, since the guide says to try just that.
