Hello, I ran into a problem I don't know how to diagnose. I got a FreeBSD 6.0 box using an Adaptec SATA (fake)RAID 1210SA. Two 250 GB Maxtor hard drives are connected to this card, as a RAID1 mirror, and the resulting filesystem is correctly mounted and NFS exported. When the traffic rises on those disks, especially when I copy a big file (around 700 MB or so) on the exported file system, the system hangs displaying "ata4 : DISCONNECT required". ata4 is the first SATA controller on the Adaptec card. The card and the disks are brand new, and the motherboard is a Tyan Tiger LE (dual Pentium 3). Do you have any clue, or just maybe a way to analyse this problem ? Should I post the dmesg, if that can help ? Thanks in advance for any advices or clues. Best Regards, Guillaume de Vinzelles
