On a system with 2 IDE buses and 4 disks (2 per bus), is it a good idea to use RAID 5 / Vinum? I read of issues regarding performance and fault tolerance on linux raid when you put two disks on one bus, and it sounded like that should apply to freebsd too, but I can't find a specific mention in the vinum documentation. One problem mentioned there that if a disk goes down, it can take the bus and therefore the other disk down with it: it doesn't matter if the data on the other disk is safe and therefore the system can be brought back up without data loss. But is there a likelihood of the other disk being corrupted in such an event? If there are performance issues with slave disks, are they likely to be show-stopping? Any real-world experiences? Thanks, Rahul. ps the linux document was http://linuxdoc.org/HOWTO/Software-RAID-HOWTO-3.html To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
