[DRBD-user] drbd 0.8 primary/primary limit question

[Joseph Koenig]

If you're going to run OCFS anyway,  you could easily just run DRBD  
in primary/secondary mode, with heartbeat to manage the failover.  
Just export the device via iSCSI and you're good to go. Then, if you  
add a 3rd web server, it doesn't matter. Use DRBD/OCFS/iSCSI to make  
yourself a redundant SAN.
