But from the complains, did you try removing the problematic keys (ipoib is part of netdev, not network. network has no knowledge of the device type)? Also are you sure <tt>80:00:02:08:fe:80:00:00:00:00:00:00:e4:1d:2d:03:00:6f:85:11 is the mac address? It is clearly more than 48 bits. </tt> <div class="moz-cite-prefix">On 7/29/24 08:43, Chandler Sobel-Sorenson wrote: </div> <blockquote type="cite" cite="mid:679330b5-1056-48bb-a7dc-b08c01c56367@genome.arizona.edu"> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> I'm quite frustrated having spent many hours and little success, when things were perfectly fine before our backup generator decided not to kick in and power surges ensued, messing up all kinds of things stupid electrons. We have a server that is a bit more important than the others, runs LDAP and hosts our home directories, and runs the subnet manager for an Infiniband network. The main uplink is a 2x10gbe bond device, and there's a local 1gbe 10-net interface/network, and an Infiniband with IPoIB. The main issue is getting the IPoIB working. The bond and its 2 links work fine after the machine boots, but whenever I restart systemd-networkd, it becomes unreachable even though there aren't any problems reported in the system logs and <tt>networkctl</tt> reports it's still routable. The only thing I've figured to get it reachable again is to reboot the system, so I'd like to figure out the problem there because that shouldn't be happening. The IPoIB is driving me nuts, I read through all of systemd.network and systemd.netdev docs, and it's somehow become rogue and unmanaged when it used to be configured. systemd-networkd keeps telling me about unknown keys and unknown sections, even though they were all added in versions previous to the current, which is: systemd 252 (252.26-1~deb12u2) running on Debian 11 Linux 5.10.0-20-amd64 Below are the configs and messages from systemd.
