Just an addition: in general there are no log messages in
/var/log/glusterfs/ (if you don't all 'gluster volume ...'), but on
the node with the lowest load i see in cli.log.1:
[2018-08-22 06:20:43.291055] I [socket.c:2474:socket_event_handler]
0-transport: EPOLLERR - disconnecting now
[2018-08-22 06:20:46.291327] I [socket.c:2474:socket_event_handler]
0-transport: EPOLLERR - disconnecting now
[2018-08-22 06:20:49.291575] I [socket.c:2474:socket_event_handler]
0-transport: EPOLLERR - disconnecting now
every 3 seconds. Looks like this bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1484885 - but that shoud
have been fixed in the 3.12.x release, and network is fine.
In cli.log there are only these entries:
[2018-08-22 06:19:23.428520] I [cli.c:765:main] 0-cli: Started running
gluster with version 3.12.12
[2018-08-22 06:19:23.800895] I [MSGID: 101190]
[event-epoll.c:613:event_dispatch_epoll_worker] 0-epoll: Started
thread with index 1
[2018-08-22 06:19:23.800978] I [socket.c:2474:socket_event_handler]
0-transport: EPOLLERR - disconnecting now
[2018-08-22 06:19:23.809366] I [input.c:31:cli_batch] 0-: Exiting with: 0
Just wondered if this could related anyhow.
