Greetings, Is there a way, either on the Lustre clients or (preferably) OSSes, to determine how many I/O operations each Lustre client is performing against the filesystem?
I know several ways of finding the number of *bytes* read or written by a client (or even on a per-job basis with job_stats), but we suspect we have some clients overwhelming our filesystem with large numbers of small I/O requests, and I don't know how to find per-client (or per-job) I/O operation counters. This is a Lustre 2.5 system.
