Hi, All,
We create a GlusterFS cluster with tiers. The hot tier is distributed-replicated SSDs. The cold tier is a n*(6+2) disperse volume. When copy millions of files to the cluster, we find these logs: W [socket.c:3292:socket_connect] 0-tierd: Ignore failed connection attempt on /var/run/gluster/39668fb028de4b1bb6f4880e7450c064.socket, (No such file or directory) W [socket.c:3292:socket_connect] 0-tierd: Ignore failed connection attempt on /var/run/gluster/39668fb028de4b1bb6f4880e7450c064.socket, (No such file or directory) W [socket.c:3292:socket_connect] 0-tierd: Ignore failed connection attempt on /var/run/gluster/39668fb028de4b1bb6f4880e7450c064.socket, (No such file or directory) … And then the copy process seems to be suspended. The command df hangs in the client machine. But if I restart glusterd, then the copy process continues. However, several minutes later the problems happens again. Later we find the problem seems to happen when creating directories. The GlusterFS version is 3.11.0. Does anyone knows what’s the problem? Is it related to tiering? Thanks, Paul
