We have faced an issue where we have installed Cumulative Update on SharePoint 2010 on all SharePoint servers in the farm (APP/FE/Index servers) but on running configuration wizard it reports that there are missing patches / updates.
We cross verified and found nothing is missing on any of the servers & all the servers have identical binaries.
For resolving this issue, We have used the following command to run the config wizard.
psconfig.exe -cmd upgrade -inplace b2b -force -cmd installcheck -noinstallcheck
If someone else is facing the same issue, this tip will be helpful.
