So till now i'm going to try this way: drbd0 = mail block device primary/primary drbd1 = mysql block device primary/secondary drbd2 = web block device primary/primary Is there any cons against this setup? All of the blocks are on top of LVM partitions. I'll use drbd 8.0.5 and heartbeat 2.1.2 (this is the last in debian). Thank you Pier
