Hello all, Four-node client-side replication setup running 3.0.0 throughout. Config generated via : $ /usr/bin/glusterfs-volgen --name replicated --raid 1 s01:/opt/gluster s02:/opt/gluster Connected via private gigabit LAN. The hardware in each of the four nodes is identical. Running the following script on one of the clients : --- #!/bin/bash loop=0 while [ $loop -lt 100 ] do (time /usr/sbin/bonnie++ -d /opt/gluster/bonnie -u root) 3>&1 2>&3 | tee -a bonnie-single-c01.log done --- [root at c01 ~]# # bonnie++ 2>&1 | grep Version Version: 1.03 The time to completion has been slowly creeping upwards. Granted, the full run hasn't completed yet, but a clear trend appears to be forming : [root at c01 ~]# grep real bonnie-single-c01.log real 15m4.444s real 15m49.245s real 16m44.263s real 16m55.868s real 17m16.479s real 18m4.800s real 19m18.089s real 20m59.218s real 22m58.493s real 22m25.134s real 23m36.715s real 25m4.022s real 29m36.527s real 26m26.325s real 28m37.396s real 35m4.289s real 32m41.834s real 34m33.418s real 37m1.098s real 38m10.750s real 46m14.002s real 40m15.416s real 36m53.414s real 44m46.302s real 38m57.842s real 41m55.745s real 46m41.493s real 54m12.818s real 52m53.408s real 36m20.212s real 40m1.991s real 54m54.110s real 57m57.162s real 57m53.896s real 62m56.905s real 65m53.524s real 67m54.105s As a control, i ran the same script with a local filesystem target on the other client : [root at c02 ~]# grep real bonnie-local-c02.log real 3m42.788s real 3m43.251s real 3m42.568s real 3m42.533s real 3m41.764s real 3m43.305s real 3m42.536s real 3m43.052s real 3m44.406s real 3m42.894s real 3m43.639s (cut for brevity - all 100 runs are around this time mark.) It is perhaps worth noting that the load on c01 (running the gluster tests) has been creeping up as well. It started at basically 0, and is now at 4.03, 3.94, 3.27 . Any ideas what's going on ? -- Daniel Maher <dma+gluster AT witbe DOT net>
