> Hi All,
> I know pacemaker booth is being used for geographical redundancy.
> Currently I am using pacemaker/corosync for my local two-node redundancy.
> As I understand, booth needs atleast 3 nodes to work correctly to do the
> automatic failovers. So it does not fit my requirements.
> Few queries are
> 1) Can I make use of my current pacemaker/corosync to make it work across
> my two geographical nodes for automatic failovers, considering I am ready
> to ignore split-brain scenarios. I may need to tweak some timers I believe.
> Is this approach possible?
> 2) Any disadvantages of going this way?
> Thanks,
