Hello Scalers,
First, let me say Happy Thanksgiving to those of us in the US and to those beyond, well, it's a still happy day seeing we're still above ground! 😊 Now, what I have to discuss isn't anything extreme so don't skip the turkey for this, but lately, on a few of our compute GPFS client nodes, we've been noticing high CPU usage by the mmfsd process and are wondering why. Here's a sample: [~]# top -b -n 1 | grep mmfs PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 231898 root 0 -20 14.508g 4.272g 70168 S 93.8 6.8 69503:41 mmfsd 4161 root 0 -20 121876 9412 1492 S 0.0 0.0 0:00.22 runmmfs Obviously, this behavior was likely triggered by a not-so-convenient user job that in most cases is long finished by the time we investigate. Nevertheless, does anyone have an idea why this might be happening? Any thoughts on preventive steps even? This is GPFS v4.2.3 on Redhat 7.4, btw...
