The binary SLES packages are fine; it is the source packages that may be problematic, depending on your config. There is a bug filed against this now (22913), so no doubt it will be fixed in a subsequent release. In regard to your testing, it is easy to check if a client is mis-behaving; run: #cat /dev/zero > /lustre/filesystem & and watch the client IO stats with: #watch -n 1 cat /proc/fs/lustre/llite/*/stats If getxattr is going up with write_bytes, then you have a problem.
