[Kristián Feldsam]

and if is usual to "can't unmount drbd because kernel is using it" you probably have something bad configured (resources order) in pacemaker. Would you please share your config?

The node went into its usual "can't unmount drbd because kernel is using it" and got stonith'ed in the middle of yum transaction.
