Hello, I'm having big problems trying to get RAID5 to work under vinum. I'm not sure what the problem is. Here is my setup: - Abit BP6 motherboard with 2x400Mhz celerons - 512MB of RAM - One Adaptec 2940 SCSI card with a 9 GB drive and a CDROM attached - Two Promise ATA/100 Cards (Fastrack/100LP and Ultra/100TX2) - 7 60 GB Maxtor drives (brand new) - FreeBSD 4.4-Stable (cvsup'd about 2 weeks ago) The 7 drives are connected to various headers on the Promise cards (ie, none are connected to the HPT Headers on the motherboard, since I've had about a billion problems with it, even with the latest HPT BIOS (1.28)). Now, the problems I've been happen after successfully getting the RAID5 volume up and running (setting up the volume, initting it, and newfsing it). Under heavy I/O (when xferring a 4GB file over at about 2MB/s) it gets about halfway through the xfer, and then one of the controllers will time out and jump down to PIO mode, and then the rest follow. After this happens, at a random time after, the box freezes up resulting in huge data corruption on the volume. Also, one of the drives always goes stale, requiring me to start it again which sometimes results in a freeze after a while. I guess my question is, with all the problems I've had with the BP6 board, and assuming I've exhausted all my options (I have spent a significant amount of time trying to get this to work), is there a better hardware combo to do this with? If so, I'll relegate the bp6 to 5.0-current testing =) Thanks! Jason To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
