When you are running the above series of commands, can you instead do this: # cd /mnt/usr # mount # dump 0af - /usr | restore xf - & # iostat -c10 Give us the output of mount, and first 10 samples from iostat to see what kind of throughput you are getting, and how the filesystems are mounted. I don't know how many recommendations I'll be able to suggest after that, but it will show us more what's going on. Cheers, Derek
