upgrade from 11.1 to 11.2

Thanks for reading my post
I upgrade the system from 11.1 to 11.2 seems everything work fine, no error no warning, after a reboot the consol show :
mount error while loading shared libraries: libvolume_id.so.1: Cannot open shared object file: No such file or directory.
when I try to repair the system the repair tool cannot find the root partion, any sugession please.

I recommend a clean new install. There are just too many differences to do an upgrade.When installing tell the installer NOT to format the home partition to preserver your data and personal settings.
