We get operation 'mds_connect to node failed' every 10 minutes or so on our OSSs. Example: /var/log/messages-20190224:Feb 24 02:07:10 foss4 kernel: LustreError: 11-0: foxtrot-MDT0000-lwp-OST003e: operation mds_connect to node 10.21.22.10@tcp failed: rc = -52
What could be causing this? Kind regards, Campbell

Campbell I think that the issue is that you are carrying the patch for Peter |

Thanks Peter. I am not sure whether it is actually causing an issue for our workloads. I'm hoping we can go for the official release - any idea roughly on when it will hit the street? Cheers, Campbell |

The exact timing depends on testing results but I would hope that the release is out within a couple of weeks. |
