There was a recent thread that suggested a mismatch in the block sizes between LVM (512b), and 3ware controllers (4kb). This is apparently resolved (or helped) by enabling the write cache on the 3ware controller. This effectively requires the battery backup unit for the controller, unfortunately 3ware doesn't allow a BBU on their 2 port 9650SE (solder pads are there though...) Is there a method of tuning the block sizes between the layers to free up this bottleneck, or am I stuck (or better off) repartitioning the disks and running ext3 directly on the disk? Chris
