I just wanted to have an extra pair (or a dozen) of eyes look this configuration over before I commit to it (tested it in VMWare just in case, it works, so I am considering doing this on real hardware soon). I drew a nice diagram: http://www.pastebin.ca/1460089 Since it doesnt show on the diagram, let me clarify that the geom mirror consumers as well as the vdevz for ZFS RAIDZ are going to be partitions (raw disk => full disk slice => swap partition | mirror provider partition | zfs vdev partition | unused. Is there any actual downside to having a 5-way mirror vs a 2-way or a 3-way one? - Sincerely, Dan Naumov
