I am trying to set up a demo OpenHPC cluster on VMware with Rocky 9.5 as base OS and my compute-nodes are unable to launch NetworkManager.service, which is obviously pretty poor for a compute node. Turns out that NM does not operate because DBus is not running. This is apparently a known bug, but I am lacking the required subscription to access the solution.
Anyone around here with full access to Red Hat’s knowledgebase article (ERROR launcher_run_child @ ../src/launch/launcher.c +325: No such file or directory - Red Hat Customer Portal)? Thanks.
If I’m understanding what you’ve linked and what you’re saying, you are trying to deploy a cluster with VM images. If you are making VM images, they may not be sealed properly or there are missing steps.
Either way, the first thing I’d check for first is permissions. Check rpm -V filesystem to see if anything comes up. If it does, you can fix them:
% rpm --setperms filesystem
And then try rebooting or starting the dbus-broker service and see what happens.
The second thing I’d check is /etc/machine-id. If it exists, ensure the permissions are 644 or 444. Also ensure there’s a value in it. Typically sealed images should have uninitialized in it. If it doesn’t exist, you will need to create it with uninitialized in it.
Same as above, reboot the system after making any changes.
