If you can provide examples of what issues you're having, I will be 
happy to try an help.

You need to get them from a 3rd party repo (or install from source). I 
personally still use 8.3.16 (consistency during "Anvil!" generations), 
but I know that 8.4 is fine on EL6 (and EL7, to address an earlier 
comment). I have my own repos with these packages, but you would likely 
be better served using the ELRepo ones.

The only real difference is to s/83/84/:

+ yum install drbd84-utils kmod-drbd84
- yum install drbd83-utils kmod-drbd83

If you run into any troubles, please share details and I am sure we'll 
get you sorted out in no time.

Cheers
