My proposal for geom_raid5 is ready so far... If somebody wants to test it, he or she can download it from http://home.tiscali.de./cmdr_faako/geom_raid5.tbz I was too tired to test it... It seems to read in the non-degraded case... :-) Rebuild is not possible, so I still have some work to do... Oh! And I just had the idea, that immediately after creation a rebuild is necessary. Or isn't it? Currently I dont do that... Has somebody a nice test suite for geom_mirror? With geom_nop consumers? Or so? Does somebody know statistics about the probability of a fatal error in a RAID5 in comparison to a MIRROR? I mean: Since a RAID5 causes more work for the hardware (for more than 2 consumers a write needs at least 2 reads and 2 writes), it is not so trivial...
