[CentOS] re-installing a package without removing it?

Hello,

I've just noticed that the file /etc/ha.d/resource.d/drbddisk, which belongs to package drbd-8.0.6-1.el5.centos, is missing from one of my test machines:

# rpm --verify drbd S.5....T c /etc/drbd.conf missing /etc/ha.d/resource.d/drbddisk

I'm looking at this as an opporunity to learn something about RPM which bugged me for a while - in Debian, aptitude and apt-get provide options to re-install existing package without removing it.

If I understand this correctly, then "rpm -i --force drbd-8.0.6-1.el5.centos.rpm" would re-install the package. Is this correct?

The rpm solution would require me to find and manually download the rpm file. Is there a way to do this through yum?

Thanks,
