A number of people have complained about problems with gvinum running RAID 5. I haven't been following up on this in the past couple of months, but if you're looking for bugs, you might want to contact Olivier Cochard, the lead of the freenas project. http://www.freenas.org/ On 9/12/06, Mark Bucciarelli wrote: > > Is anybody using gvinum raid5 in production with 6.1-release?
