Looking through the PR database I found PR docs/58615 which I believe can be closed. The PR, also found here: http://www.freebsd.org/cgi/query-pr.cgi?pr=docs/58615 , mentions that the handbook chapter about vinum (chapter 19) lacks information about raid 5. When I looked at the handbook I noticed that the vinum chapter mentions raid 5. Regards! Niclas
