1594972 : naf-desy-cms redirector pointing to node scheduled for reboot¶
Created: 2026-04-22T14:41:28Z - current status: new¶
Anonymized Summary:
A user encountered login issues after a scheduled reboot of a NAF login node ([NODE_NAME]). When attempting to log in via the load-balanced alias (naf-[EXPERIMENT].desy.de), they were redirected to the rebooted node, which denied access. The issue was resolved by directly logging into an alternative node ([ALTERNATIVE_NODE]). The user requests that rebooted nodes be temporarily removed from the redirector pool to prevent similar issues in the future.
Suggested Solution/Next Steps:
1. Temporary Removal from Redirector:
The NAF team should ensure that nodes undergoing maintenance (e.g., reboots) are excluded from the load-balanced alias (naf-[EXPERIMENT].desy.de) until fully operational. This prevents users from being redirected to unavailable nodes.
-
User Workaround: Until the redirector is updated, users can bypass the issue by directly logging into an alternative node (e.g.,
naf-cms23.desy.deinstead ofnaf-cms.desy.de). -
Communication: If possible, notify users in advance about scheduled reboots (e.g., via email or a status page) to minimize disruption.
