This is why I don't understand why it has been ignored - it is easily reproducable using stock Adaptec SATA controllers, standard SATA drives, and a gmirror RAID 1 configuration. This is pretty pedestrian stuff here Robert.... Two disks on one adapter, on a PCI bus..... I'll pull over 6.0-BETA1, rebuild the array (that is the time-consuming part of this test - takes 6-8 hours for the rebuild to run) and see if it fails during a buildworld. -- -- Karl Denninger (karl@denninger.net) Internet Consultant & Kids Rights Activist http://www.denninger.net My home on the net - links to everything I do! http://scubaforum.org Your UNCENSORED place to talk about DIVING! http://homecuda.com Emerald Coast: Buy / sell homes, cars, boats! http://genesis3.blogspot.com Musings Of A Sentient Mind
