I tried using LVM2 on a 2.6.9 kernel to stripe together four 1T LUNs from two 3 Ware 9000 SATA raid controllers to make ~4T file system, but experienced file corruption under heavy I/O loads. In copying large directories into the file system (via tar+rsh/ssh or rsync+rsh/ssh), I'd get files that seemed to have blocks exchanged with a different file. I saw this using XFS, Reiserfs, and EXT3 as the file system in the LVM2 stripe. Some tests I made of a similar configuration using 'md' instead of LVM2 were more successful, but I didn't put quite the I/O load on that configuration.
