Not to nitpick toooo much, I had the opportunity to play follow along with this page and it is still needs help: "You divide the chunk size by the block size..." BUT then has "(chunk size * block size)". The "*" should be "/". The example for RAID 5 is fine, but the RAID 10 example sentence may be better after the code example as to not confuse a reader for which of the 2 options the code is for. The mkfs.ext3 command exampled is not supported in CentOS 4 or 5 . The "-E stripe-width=48" is not allowed according the "man mkfs.ext3". If examples of performance improvements could be added like: #sync ; time dd if=/dev/sdc1 of=/dev/null bs=1M count=20480 (default mkfs.ext) 221474836480 bytes (21 GB) copied, 126.272 seconds, 170 MB/s real 2m6.275s (stride tweak only) 21474836480 bytes (21 GB) copied, 107.209 seconds, 200 MB/s real 1m47.212s pjwelsh
