Hello All, In the not too distant future I will be commissioning a new CentOS (5.4?) box with 4 identical SATA drives. I'd like to set them up as RAID 1+0 for speed and redundancy. I've read the RHEL 5 deployment guide on raid setup and it seems to cover the basics of software raid pretty well, but doesn't cover 1+0. Does anyone have a reference for that kind of configuration? I'd also like to have two virtual domains, one for CentOS and one for Debian. any suggestions for setup docs for that kind of arrangement? TIA. Dave -- When addiction becomes commonplace in a society, people become addicted not only to alcohol and drugs, but to a thousand other destructive pursuits: money, power, dysfunctional relationships, or video games. A social perspective on addiction does not deny individual differences in vulnerability to addiction, but it removes them from the foreground of attention, because social determinants are more powerful.
