I bit the bullet recently and moved a raft of servers over to 2.6.11 and RAID-6. Biggest single partition is 1.3TB over 8 drives. Oddest is probably 4 drives in a RAID-6 setup, but hey ... (All are running Debian Woody FWIW) So-far so good. No crashes, no failures. Performance is adequate (Mix of Opteron and Hyperthreading Xeon processors, SCSI and SATA drives, Gb Ether) and I'm hoping they'll stay that way for the next 3 years until they are replaced. 6 years ago, I built mt first (Linux S/W) RAID-5 system... (and that server was only retired last year) Lets hope RAID-6 does just as good a job!
