I'm using pacemaker and corosync for drbd/gfs2/ILO STONITH management and keepalived just for vrrp.
I'd just typically used keepalived for VRRP/VIP stuff so I reached for that. As far as drbd, all of the boxes doing that are connected via crossover cable and are running dual-primary. I'd be interested in the replication across multiple DCs. That's a much more labourous task. One thing that does happen is that each system writes to /storage(gfs2 clustered filesystem via drbd)/$hostname. So both systems get a copy of each other under a different folder and they never write to each other's directory. You have to grep through 2 folders but since the dir structure is identical, it's just another wildcard.

Why would use keepalived as well as pacemaker/corosync? It seems to me that you would use one or the other. I've given serious consideration to setting up pacemaker/corosync between my two archive servers (in two different datacenters) and having the 'active' one copy data to the 'inactive' one as the logs roll, just so that the arcives are identical so that rsync can patch gaps (and when it can't deliver the messages to the remote system, keep both copies as they will be different) I haven't completely satisfied myself that I cover all failure modes with this, so I haven't implemented it yet.
