When I execute "yum upgrade" on both CentOS 5.0 Xen DomU and CentTOS 5.1 Xen Dom0 I get:

--> Finished Dependency Resolution Error: Missing Dependency: drbd >= 8.0.12 is needed by package kmod-drbd-xen

"yum list drbd*" gives:

Available Packages drbd.x86_64 8.0.12-1.el5.centos extras drbd82.x86_64 8.2.6-1.el5.centos extras

I searched for any mention ot drbd in my yum configuration (in case it was excluded) but didn't find anything.

What could be the cause?

Thanks,
