    The only log available for a client process is located at
      /var/log/glusterfs/<mnt_path>. You can also see if there is
      anything in the bricks logs,

        Hello,
         
        I have GlusterFS 3.8.8. I am using IB RDMA.
          I have noticed during Write or Read the throughput doesn’t
          seem consistent for same workload(fio command). Sometimes I
          get higher throughput sometimes it quickly goes into half,
          then stays there.
         
        I cannot predict a consistent behavior
           every time when I run the same workload. The time to complete
          varies. Is there any log file or something I can look into, to
          understand this behavior. I am single client(fuse) running 32
          thread, 1mb block size, creating 200GB or reading 200GB files
          randomly with directIO.
