Foreman/Katello has been running (mostly) smooth for 2 years now, but the server certificate was expiring so we updated it and ran the appropriate commands. Everything appeared to work fine, until i updated to latest Patch level and Foreman got properly restarted.
Should be noted here that the new certificate has the same Root, but a new Intermediate root (issuer).
First problem I encountered was subscription manager got a CA error on all 260 hosts, I ended up having katello recreate the pulp certs and ran a full clean and re-register on all 260 hosts - Everything appeared to work fine after that.
However, a couple days later we started noticing that Foreman would grind to a halt after a few hours and after tracing logs, the issue appears to be this Candlepin error causing hangups ( it’s at least the only error in the logs )
I probably messed something up along the way through this process, but for some reason everything works Except the system doesn’t appear to trust the Candlepin cert and i can’t figure out how to force katello to recreate it or fix this issue.
Any help would be greatly appreciated.
Absolute worst case scenario, i’d have to restore from backups since mid February and try again, discarding every parameter change and new host that has been created since
