This is not really about a problem - more about seeking some advice before I get going so I don’t create a mess.
I have a working icinga2 with a number of nodes reporting in - what used to be called passive checks; this works fine. I am now building a compute cluster with slurm as the workload manager - each node boots up via PXE to debian 12.
When I set up a new node, I use icinga2 node wizard
, and it asks for the common name, which will be the FQDN of the node; however, the compute nodes are diskless servers, so I have to configure this on the boot image, and the node’s name isn’t known. The question then is, is this possible? Can I just use the same common name for all the nodes, or will this cause a conflict somewhere?
