Hello All- I have been experimenting with the "gluster volume top" commands in the search for performance bottlenecks. For some bricks fewer than list-cnt files are listed for read and write speed tests, and for some bricks no filenames are listed at all even though throughput figures are reported for all the bricks. See below for example, which shows read-perf results from two bricks on the same server. Brick: bdan13.nerc-essc.ac.uk:/nemo/glusterfs Throughput 51.20 MBps time 0.0000 secs No entries in list Brick: bdan13.nerc-essc.ac.uk:/nemo8/glusterfs Throughput 128.00 MBps time 0.0000 secs MBps Filename Time ==== ======== ==== 0 ...ice_assm/1989/ORCA025-FOAM_y1989m12_gridT.nc 2012-01-04 11:44:12.71083 0 ...ice_assm/1989/ORCA025-FOAM_y1989m05_gridT.nc 2012-01-04 11:44:09.250759 This happens whatever the value of list-cnt. Does this indicate a problem with those bricks, or is there a bug in the gluster "top" feature? -Dan.
