Well, count on fuser only as root. So, if you are a non-root user and the operating system

can result in incorrect decisions.

(for many reasons) but back to the OP one additional point in your environment is the HBA/Network part: If you have mirrored logfiles, you write every bite twice (regardless on which LUN, the bits have to use the HBAs and Network). I could not find any information in the posts if this can be a bottleneck in your environment, just keep it in mind.
