[Pacemaker] best Way to build a 2 Node Cluster with cold Standby ?

[Hauke Bruno Wollentin]

Hi Hauke,

personally I won't use DRBD for a case like that because of the _missing_ 
replication here.

Imho your idea will work, but it would be easier to manage to use some kind of 
file synchronisation like rsync, unison etc. when the cold standby node comes 
up.

cheers,
Hauke
