The orginal poster was doing a RAID-5 across 3 disks, and has stopped commenting but it's probably because that's all the hardware he could scrounge. I am a staunch member of BAARF however and don't trust RAID-5/6 for a New York second. See http://www.baarf.com/ We do ZFS RAID-10 across LUNs provided from arrays on a SAN through multipathing. Within the arrays the LUNs are RAID-5. Belt AND Suspenders. Your mere RAID-6 doesn't pass my standards for reliability and high availability, because there can still be errors along the path that are not caught until too late. I can take a hammer to multiple pieces of equipment without downtime. But we are a datacenter with 50K+ users who get very cranky when mail is down for any amount of time at all. I've worked in smaller departments and different standards apply there. YMMV. Once you go ZFS you'll never go back, it's like the first time you had a journalled filesystem and thought ah some relief from worries over corruption! ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
