There are stats for this, but not in a single location. The metadata stats can be seen with e.g. "llstat -i 1 mds" on the MDS, and the IO stats can be seen on the individual OSTs with "llstat -i 1 ost_io". There are other stats counters, please read the documentation. http://manual.lustre.org/manual/LustreManual16_HTML/DynamicHTML-20-1.html > Last is there a way to set a system wide default quota?
