Hi! I'm building a new server (4.8) which includes Highpoint HPT370 ATA RAID controller. I have experience with several SCSI RAID controllers but this is the first ATA RAID for me. I have 2 80 GB disks, so I created a RAID1 array on them and installed FreeBSD. Everything seems just fine in dmesg: ar0: 78167 MB <ATA RAID1 array> [9964/255/63] status READY subdisks: 0 READY ad4: 78167 MB <Maxtor 6Y080l0> [158816/16/63] at ata2-master UDMA100 1 READY ad6: 78167 MB <Maxtor 6Y080l0> [158816/16/63] at ata3-master UDMA100 Mounting root from /dev/ar0s1a ...and the system runs like a champ. So, to simulate a disk failure, I powered off the machine, disconnected the Slave drive and restarted the machine. The results: ar0: 0 MB <ATA RAID1 array> [0/0/0] status READY subdisks: 0 FREE ad4: 78167 MB <Maxtor 6Y080l0> [158816/16/63] at ata2-master UDMA100 Mounting root from ufs:/dev/ar0s1a Root mount failed: 6 and I'm left sitting at the 'mountroot>' prompt. When I reconnect the slave, everything works fine again. With master disconnected, the messages are slightly different, but the net result is same (0 MB RAID1 array, root mount failed). What am I missing? -- Toomas Aas | toomas.aas@raad.tartu.ee | http://www.raad.tartu.ee/~toomas/ * RUNTIME ERROR 6D at 417A:32CF : Incompetent user
