vSAN OSA hosts may take longer than usual during the first reboot after upgrading to ESXi 8.0 Update 3.

Products

• VMware vSAN 7.x
• VMware vSAN 8.x

Issue/Introduction

When upgrading vSAN OSA hosts from vSphere version 7.x/8.x to vSphere 8.0 Update 3 and vSphere 8.0 Update3b, ONLY the first reboot after the upgrade will take longer to initialize disk-groups during boot sequence and  all other subsequent reboots will NOT be affected by this.

The reboot time may vary between 5mins to 45 mins depending on the type of workload running on the hosts prior to upgrade.

Logs messages indicate that Fast recovery failed with "Invalid metadata" at first reboot:
