Howdy, I'm setting up several gluster 3.12 clusters running on CentOS 7 and have having issues with glusterd.log and glustershd.log both being filled with errors relating to null client errors and client-callback functions. They seem to be related to high CPU usage across the nodes although I don't have a way of confirming that (suggestions welcomed!). in /var/log/glusterfs/glusterd.log: csvc_request_init+0x7f) [0x7f382007b93f] -->/lib64/libglusterfs.so.0(gf_client_ref+0x179) [0x7f3820315e59] ) 0-client_t: null client [Invalid argument] [2017-09-15 00:54:14.454022] E [client_t.c:324:gf_client_ref] (-->/lib64/libgfrpc.so.0(rpcsvc_request_create+0xf8) [0x7f382007e7e8] -->/lib64/libgfrpc.so.0(rpcsvc_request_init+0x7f) [0x7f382007b93f] -->/lib64/libglusterfs.so.0(gf_client_ref+0x179) [0x7f3820315e59] ) 0-client_t: null client [Invalid argument] This is repeated _thousands_ of times and is especially noisey when any node is running gluster volume set <volname> <option> <value>. and I'm unsure if it's related but in /var/log/glusterfs/glustershd.log: [2017-09-15 00:36:21.654242] W [MSGID: 114010] [client-callback.c:28:client_cbk_fetchspec] 0-my_volume_name-client-0: this function should not be called --- Cluster configuration: Gluster 3.12 CentOS 7.4 Replica 3, Arbiter 1 NFS disabled (using Kubernetes with the FUSE client) Each node is 8 Xeon E5-2660 with 16GB RAM virtualised on XenServer 7.2 root@int-gluster-03:~ # gluster get glusterd state dumped to /var/run/gluster/glusterd_state_20170915_110532 [Global] MYUUID: 0b42ffb2-217a-4db6-96bf-cf304a0fa1ae op-version: 31200 [Global options] cluster.brick-multiplex: enable [Peers] Peer1.primary_hostname: int-gluster-02.fqdn.here Peer1.uuid: e614686d-0654-43c9-90ca-42bcbeda3255 Peer1.state: Peer in Cluster Peer1.connected: Connected Peer1.othernames: Peer2.primary_hostname: int-gluster-01.fqdn.here Peer2.uuid: 9b0c82ef-329d-4bd5-92fc-95e2e90204a6 Peer2.state: Peer in Cluster Peer2.connected: Connected Peer2.othernames: (Then volume options are listed) --- Volume configuration: root@int-gluster-03:~ # gluster volume info my_volume_name Volume Name: my_volume_name Type: Replicate Volume ID: 6574a963-3210-404b-97e2-bcff0fa9f4c9 Status: Started Snapshot Count: 0 Number of Bricks: 1 x 3 = 3 Transport-type: tcp Bricks: Brick1: int-gluster-01.fqdn.here:/mnt/gluster-storage/my_volume_name Brick2: int-gluster-02.fqdn.here:/mnt/gluster-storage/my_volume_name Brick3: int-gluster-03.fqdn.here:/mnt/gluster-storage/my_volume_name Options Reconfigured: performance.stat-prefetch: true performance.parallel-readdir: true performance.client-io-threads: true network.ping-timeout: 5 diagnostics.client-log-level: WARNING diagnostics.brick-log-level: WARNING cluster.readdir-optimize: true cluster.lookup-optimize: true transport.address-family: inet nfs.disable: on cluster.brick-multiplex: enable -- Sam McLeod @s_mcleod https://smcleod.net _______________________________________________ Gluster-users mailing list Gluster-users@xxxxxxxxxxx http://lists.gluster.org/mailman/listinfo/gluster-users
