When upgrading NSX manager you might encounter an error for ‘large database table’ or ‘insufficient disk space’ or ‘database disk usage’. These errors can either be because the log directory in /common/logs is full or you actually have a valid database full problem.
Cloud Director specifically requires devices to be gracefully removed from itself prior to removing the devices from the vCenter or physically removing them from the DC. If you have this issue then it’s best to see if you can power back on devices or restore the VMs and then remove them in Cloud Director properly as that is the best method and does not require database manipulation. If you do not have that option then you will need to raw edit the postgres DB.
When upgrading from NSX 6.4.2, 6.4.3, or 6.4.4 you might receive the error message “Upgrade target version 6.4.10.17626462 is same or less than the current version 6.4.4.”
