OK, the inodes that are corrupted are different, so there's still something funky going on here. I still would suggest replacing the RAID controller to rule that out as the cause. FWIW, do you have any other servers with similar h/w, s/w and workloads? If so, are they seeing problems? Can you recompile the kernel with CONFIG_XFS_DEBUG enabled and reboot into it before you repair and remount the filesystem again? (i.e. so that we know that we have started with a clean filesystem and the debug kernel) I'm hoping that this will catch the corruption much sooner, perhaps before it gets to disk. Note that this will cause the machine to panic when corruption is detected, and it is much,much more careful about checking in memory structures so there is a CPU overhead involved as well.
