Issue/Introduction

  • The NSX-T Manager Upgrade seems to be stuck and when the "get upgrade progress-status" command is issued to check the status following is observed:
run_migration_tool [2021-06-09 20:59:46 - ] FAILED            
run_migration_tool [2021-06-15 19:59:15 - ] IN_PROGRESS
Status: Corfu Infrastructure Server is not running.
  • NSX-T manager Upgrade is halted
  • In the /var/log/policy/data-migration-with-old-protobuf.log following error stack is observed:
2022-03-04T19:20:39.448Z ERROR main ClusteringCorfuCompactor - - [nsx@6876 comp="nsx-manager" errorCode="MP1" level="ERROR" subcomp="corfu-compactor"] Checkpoint failed for clustering data with namespace cbm

  • In /var/log/policy/cbm/cbm.log we see entries indicating that the system attempted to delete the PersistentQueue,

  • However, /var/log/corfu/corfu-compactor-audit.log indicates that the clean up did not go as expected.

Environment

VMware NSX-T Data Center 3.x

Cause

The persistent queues should be cleared out during an upgrade (during the reboot of the orchestrator node). In certain scenarios due to a race condition, the cleanup doesn't go through properly leaving behind some stale entries in the database, which cause the upgrade to pause.
