look inside the directory
/usr/share/openvpn/easy-rsa/2.0/keys
and see if you can find a ca.crt and ca.key file there; you can post an 
'ls -l' if you like.
If they are not there then a './clean-all' was run most likely. I hope 
you have a backup somewhere :)

These are the keys used for openvpn ; key management (generation) is 
separated from key usage by OpenVPN; the ca.pem and servercert+serverkey 
are not sufficient to generated new client keys. You will need a ca.crt 
(or ca.pem) and ca.key file for that.

HTH,

PS The openssl version does not matter in this case, as CentOS 6 is new 
enough; you could/should consider upgrading to 6.5 , however.
