(Re-sending with correct subject - sorry) Hello Carl and list members, My etc-glusterfs-glusterd.vol.log files are also flooded with warning messages like the following. bdan4: [2012-01-05 18:54:30.385095] W [socket.c:1494:__socket_proto_state_machine] 0-socket.management: reading from socket failed. Error (Transport endpoint is not connected), peer (192.171.166.72:993) Some of the "peers" mentioned are actually clients but others are GlusterFS servers. The warnings seem to occur repeatedly for a period of time on all the servers and then stop for a while before starting again. I have a feeling it has something to do with NFS, because it seems to occur more frequently on servers I use to export NFS (although all are running the glusterfs NFS process). The warnings seem to coincide with the NFS processes restarting, as they did on all the servers in my cluster at 16:48 today, un-noticed by me, for no apparent reason. The warnings stopped on most servers soon after this, but they have carried on since then on the servers that are exporting NFS. I have been ignoring these warnings for some time because there didn't seem to be any adverse effects, but I am trying to solve a serious performance problem affecting some applications and I want to look at all possible causes for concern. I have seen these warnings in log files posted to the list in the context of various problems which I don't have, but I have never seen them mentioned specifically. Are these spurious warnings that can be ignored or do they point to a problem with my cluster? Any comments or suggestions would be much appreciated. Regards Dan.
