      Cause (the user action or circumstances that trigger the bug): The crm_node command mishandles node IDs when called with the dash i / dashdash cluster-id argument.

      Consequence (what the user experience is when the bug occurs): crm_node dash i / dashdash cluster-id, which is supposed to show the local node's cluster ID, sometimes shows "Node is not known to cluster" instead.

      Fix (what has changed to fix the bug; do not include overly technical details): Node IDs are now properly parsed.

      Result (what happens now that the patch is applied): The command works as intended.

      What were you trying to do that didn't work?

      Since upstream version 2.1.7 (RHEL 8.10 / 9.4), crm_node dash i / dashdash cluster-id, which is supposed to show the local node's cluster ID, can show "Node is not known to cluster" instead.

      Steps to reproduce

      1. Run crm_node -i repeatedly

      Expected results

      crm_node -i always gives the local node ID

      Actual results

      crm_node -i sometimes gives an error

      Other notes

      I (Reid) could reproduce this on Fedora 39 only after installing the pacemaker-2.1.7-5.fc39.x86_64 package from the fedora repo via dnf. When I built and installed from source, the uninitialized local variable that causes the problem was always set to 0 by gcc.
