Do you mean you updated some packages?

Any issues during the upgrade?

Does "apt-get dist-upgrade" do anything?
 
As per the PM it looks like you have some issues with the /etc/pve* DB file's and folders.

If you can post all the log's and status from the sevices as per the PM someone may be able to help you resolve the issue.
