Hello everyone, I hope you are doing well. I have a glusterfs (version 3.3.1) with 4 nodes: [root at client-fs01 ~]# gluster volume info gluster00 Volume Name: gluster00 Type: Distributed-Replicate Volume ID: 662bf991-562c-464b-8d39-1909ae378f37 Status: Started Number of Bricks: 2 x 2 = 4 Transport-type: tcp Bricks: Brick1: cliente-fs01:/export1 Brick2: cliente-fs02:/export2 Brick3: cliente:/export3 Brick4: cliente-fs04:/export4 Options Reconfigured: auth.allow: 10.* performance.cache-size: 1GB cluster.data-self-heal-algorithm: full performance.io-thread-count: 32 geo-replication.indexing: on performance.write-behind-window-size: 2MB Two nodes (client-fs03 and client-fs04) always are with high load average (I think because CPU utilization by glusterfsd daemon) [root at client-fs01 ~]# top top - 11:01:29 up 75 days, 12:41, 2 users, load average: 0.00, 0.00, 0.00 Tasks: 168 total, 1 running, 167 sleeping, 0 stopped, 0 zombie Cpu(s): 0.1%us, 0.0%sy, 0.0%ni, 99.9%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 5993104k total, 5880888k used, 112216k free, 27276k buffers Swap: 8290296k total, 127856k used, 8162440k free, 2585964k cached [root at client-fs02 ~]# top top - 11:02:25 up 31 days, 10:24, 1 user, load average: 0.00, 0.00, 0.00 Tasks: 167 total, 1 running, 166 sleeping, 0 stopped, 0 zombie Cpu(s): 0.3%us, 0.4%sy, 0.0%ni, 99.3%id, 0.1%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 5993104k total, 4168744k used, 1824360k free, 54540k buffers Swap: 8290296k total, 136952k used, 8153344k free, 607736k cached [root at client-fs03 ~]# top top - 11:02:22 up 50 days, 19:51, 2 users, * load average: 11.56, 10.33, 11.18* Tasks: 168 total, 1 running, 167 sleeping, 0 stopped, 0 zombie *Cpu(s): 68.5%us*, 14.9%sy, 0.0%ni, 16.3%id, 0.0%wa, 0.0%hi, 0.3%si, 0.0%st Mem: 5993104k total, 1817388k used, 4175716k free, 3232k buffers Swap: 8290296k total, 182976k used, 8107320k free, 19904k cached [root at client-fs04 ~]# top top - 11:02:50 up 75 days, 12:35, 2 users, l*oad average: 3.43, 3.77, 3.83* Tasks: 168 total, 1 running, 167 sleeping, 0 stopped, 0 zombie *Cpu(s): 33.9%us*, 6.1%sy, 0.0%ni, 59.9%id, 0.0%wa, 0.0%hi, 0.2%si, 0.0%st Mem: 5993100k total, 4167652k used, 1825448k free, 6804k buffers Swap: 8290296k total, 166024k used, 8124272k free, 87160k cached Each server has 4 CPUs and 6Gb memory.
