This is a much less powerful desktop system so the CPU load can’t be compared 1:1 with the systems comprising the bricks but still very high. So the issue seems to exist with both glusterfsd and glusterfs processes. <p></p></span></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif""><p> </p></span></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif""> Thanks,<p></p></span></p><p class="MsoNormal"><span

I was able to build, start, mount, and use the volume. On each system contributing a brick, however, my CPU usage (glusterfsd) is hovering around 20% (virtually zero memory usage thankfully). These are brand new, fairly beefy servers so 20% CPU load is quite a bit. The deployment is pretty plain with each brick mounting the volume to itself via a glusterfs mount. I assume this type of CPU usage is atypically high; is there anything I can do to investigate what’s
soaking up CPU and minimize it? Total usable volume size is only about 22 TB (about 45 TB total with 2x replicate). <p></p></span></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif""><p> </p></span></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif""> Thanks,<p></p></span></p><p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif""> ~Mike C. <p></p></span></p><p class="MsoNormal"></p><p> </p></div><p style="margin-top: 2.5em; margin-bottom: 1em; border-bottom: 1px solid #000"></p><pre style="white-space: pre-wrap; word-wrap:break-word; font-family: sans-serif; margin-top: 0px"><hr /><br />Gluster-users mailing list<br />Gluster-users@gluster.org<br /><a
