Re: GlusterFS throughput inconsistent

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.
