I've hunted through the various FreeBSD mailing list archives, checked http://people.freebsd.org/~msmith/RAID/ for status information, but I still can't seem to get a good feel for how well RAID is supported under FreeBSD. As far as I can tell, there is fairly decent support in FreeBSD for installing onto a RAID, and I have one system running on a Dell PERC3/DC (AMI MegaRAID) controller without any difficulty. However, for machines hidden away in a machine room somewhere, I need to know when a disk fails, be able to replace it, and have the data on the disk rebuilt without any downtime for the system. This is what I am having trouble finding information on. It appears there might be utilities available for some of the Adaptec controllers, and there is mention on Mike Smith's RAID page of a utility for the AMI controllers, but there doesn't seem to be any difinitive information on what operations are supported, where to get the software, or how to implement any of this into a production system. Somewhere I found a link labelled "FreeBSD RAID" to http://bsd.phoenix.az.us/raid/ but I have been unable to reach the site. I guess what I'm asking is, which RAID controllers under FreeBSD have the support behind them (management utilities, etc.) to provide un-interruptable service in the case of disk failure? -- Edward Glowacki glowack2@msu.edu Michigan State University To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
