Repairing a corrupt Cloudera Manager Installation

[#1]

Cloudera Manager 5.1.2 + CentOS 6

After disk failure of /usr partition, some CM installation files were lost (no backup ...). Any suggestion on how to repair the CM installation?

Only /usr was affected, therefore, configuration info in /etc/ and /var should still be OK (That's why I still hope to repair the installation) . Will extracting the RPM to replace corrupted files work?

Eventually, I extracted the CM Daemons RPM (using rpm2cpio and cpio), compared the files, and copied the missing files. CM is working again.
