I have been experimenting with the new ata RAID code and one thing I am
unable to do is to rebuild and array.
I did the following steps,
made ar0 with ad4 and ad6, fdisk'd, disklabel'd, newfs'd no problem. Then I
shutdown the machine and pulled out ad6 and put in a new blank drive.
raidtest3# atacontrol list
ATA channel 0:
Master: ad0 <Maxtor 2B020H1/WAH21PB0> ATA/ATAPI rev 6
Slave: no device present
ATA channel 1:
Master: no device present
Slave: no device present
ATA channel 2:
Master: ad4 <ST340016A/3.10> ATA/ATAPI rev 5
Slave: no device present
ATA channel 3:
Master: ad6 <ST340016A/3.10> ATA/ATAPI rev 5
Slave: no device present
ATA channel 4:
Master: no device present
Slave: no device present
ATA channel 5:
Master: no device present
Slave: no device present
raidtest3# atacontrol status ar0
ar0: ATA RAID1 subdisks: ad4 status: DEGRADED
raidtest3#
This is with a
raidtest3# dmesg | grep -i ata
atapci0: <Intel PIIX4 ATA33 controller> port 0xb800-0xb80f at device 4.1 on

ar0: 38166MB <ATA RAID1 array> [4865/255/63] status: DEGRADED subdisks:
0 READY ad4: 38166MB <ST340016A> [77545/16/63] at ata2-master UDMA100
raidtest3#
Yet, when I go to do a rebuild,
raidtest3# atacontrol rebuild ar0
atacontrol: ioctl(ATARAIDREBUILD): Operation not supported by device
raidtest3#
I guess there needs to be some way to tell the controller to use ad6 as
part of the rebuild no ?
