I have used gmirror without problem, but when I wanted to add some storage space with raid5 i failed, unfortunately it's because of the documentation: * The first question, does gvinum support raid5 today, or is it just the ol= d vinum? * On what file systems can gvinum operate? Vinum required "vinum" as the fstype, but the new geom implementation's doc says nothing about this? I have searched a lot on news-groups etc. but all I found was examples on how to set up the organisation types "concat" and "striped", but not how to setup "raid5". The documenation doesn't give me any help in this question either - actually it's the first time I have found a badly documented project in FreeBSD. But accordning to the old documentation I figured out the following configuraiton file: # cat gvinum.conf drive sata2 device /dev/ad4s1d drive sata3 device /dev/ad6s1d drive sata5 device /dev/ad10s1d volume site plex org raid5 512k sd length 305242m drive sata2 sd length 305242m drive sata3 sd length 305242m drive sata5 ~ * Is it possible to use a device's c-partiton (e.g. /dev/ad4s1c), i.e. the complete disc? * Is 512kb for the stripe size good, or can/should it be bigger when having such big subdiscs?
