I'd suggest using the noatime mount option unless you really need atime support. Using atime is likely to make many operations a lot slower. The stats you've listed don't really tell us much. The question is what the workload is, how the files/directories are layout out, and how they are being accessed from each node, Steve. -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
