I don't know the full differences between md raid and dm raid, but I followed the instructions on installing md raid on the opensuse wiki, using yast to set up the raid partitions.
Many even cheap Motherboards have RAID chips integrated. Most cheap RAID chips are not fast so RAID5 is not worth it with them. But for RAID1 wouldn't you be better served with a different Main board or a hardware RAID controller ?
Kind regards Philippe
Well, this is a home server that has not much load. I'm replacing my 2 year old home server, P-III and Suse 10.0 that has run very well for almost 2 years. Since 10.0 is becoming extinct I need to do something. I could probably use this same box for another 2 years, but it has only 1 hard drive and I decided to build a new one with opensuse 10.3, this time with raid. But a true hardware raid is too expensive and not needed in this environment. I've been reading a lot about the differences between software raid in linux and the motherboard raid options. Most linux distros recommend linux software raid over the mobo raid, claiming more flexibility to use different types of drives, no lock in to mobo drivers, etc. I suspect this is due to problems with mobo raid in the past, and a general tendency to favor open source. They do claim software raid uses more system resources. I'm not sure which way to go, but am leaning toward the software raid option (md raid). This is probably a loaded question, but any thoughts on the matter? Jim F -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
