ARTESCA Upgrade Fails to Start After OS Update

Problem Description

The ARTESCA upgrade fails to start after the operating system update.

The following error message is displayed:

Waiting for the Post OS update Job to complete
Error: Failure while running 'post-os-update' upgrade pre-checks: The post OS update Job failed check /var/log/artesca/post-os-update.log for more information

Root Cause

After updating the ARTESCA operating system, the servers may be rebooted and services may not restart fast enough, which makes the post-os-update command fail.

Problem Resolution

1. Ensure all ARTESCA services are up and running:

   [artesca-os@bootstrap ~]$
   

   sudo kubectl --kubeconfig=/etc/kubernetes/admin.conf wait pods \
   --for=condition=Ready --timeout=0 --all-namespaces \
   --selector='!job-name'
   

   Successful results will end with condition met.

   Example

   pod/zenko-operator-859d7cb7bc-9ssjr condition met
   

2. Manually launch the post-os-update command.

   [artesca-os@bootstrap ~]$
   

   sudo ./artesca-installer post-os-update
   

   
   PROGRESS - OS upgrade completed on all nodes
   

3. Resume the Upgrade process.
