This document (000021008) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Manager 4.3.x
SUSE Manager 4.2.x

Situation

After the bootstrap completed without errors and the salt-key is accepted the system does not show up in the SUSE Manager webUI system list.

In '/var/log/rhn/rhn_web_ui.log' located on the SUSE Manager server the following message is seen:

2023-02-15 08:59:55,915 [salt-event-thread-7] WARN com.suse.manager.webui.services.impl.SaltService - Got no result for grains.items on minion <name> (minion did not respond in time)

com.suse.salt.netapi.exception.SaltException: Master not found in minion configuration

Resolution

Increase the timeout by adding the following line to '/etc/rhn/rhn.conf' located on the SUSE Manager server:

java.salt_presence_ping_timeout = <value>

The default value is 4 (seconds), adjust the value within a range of 4-400 (seconds).
After this a restart of spacewalk is needed:

# spacewalk-service restart

Cause

The affected system is unable to respond back to SUSE Manager within the configured timeout
