Hi all, there are these error messages in the logs, of the type > Nov 28 14:18:13 lustre kernel: LustreError: 5932:0:(handler.c:1518:mds_handle()) operation 41 on unconnected MDS from ... I''ve got many of these, operations 101, 39, 400, 41, 49 on an MDS running Lustre 1.6.5.1, and operations 101, 33, 35, 400, 41 on an MDS running 1.6.3 The only Google result I get on this is my own post from last August. Even if this is nothing to worry about, it would be nice to know. But someone should have an idea what all these error numbers mean? Hm, "... unconnected MDS" on the very MDS, which is up and running and apparently functional - strange. Regards, Thomas
