Rebuild ICH8 RAID 5, the progress is always 0% and the partition can't be use any more. 2. A degrade RAID 5 can't boot. System hangs at boot time. CPU: Intel Core2 Duo RAM: 2GB Motherboard: ASUS P5B-E 1 x Seagate 80GB disk 4 x WD 160 GB (WD1600AAJS) ASUS P5B-E has intel matrix raid support. I am using 4 WD disks to build RAID 5. It works well on FreeBSD 6.2. The kernel can detect 4 disks and have a ar0 RAID 5 device. "atacontrol status ar0" works well, I can see RAID is READY or DEGRADE when I unplug a disk. But when I attache a new disk, add it as spare disk, then use atacontrol to rebuild to RAID, the progress is always 0%. And, the partition can't be access any more. If i try to access the partition, system hangs. Any other problem is, if I shutdown the PC and unplug 1 disk from the 4 disks RAID 5, turn on power, the system can't boot. It hangs in detect ata raid. >How-To-Repeat: 1. Use Intel ICH8 chip and create RAID 5 2. Unplug 1 disk 3. attache disk, add to spare disk, and rebuild 4. progress is always 0% 5. unplug the new disk 6, reboot 7, system hangs when detecting ata raid >Fix: >Release-Note: >Audit-Trail: >Unformatted:
