I'm in the process of setting up a DRBD 2-node cluster with 2 instances of windows server (one 2003, one 2008) virtualized in xen and a samba or possibly later iscsi data share volume. I've got CentOS 5.3 and DRBD 8.3.1 on LVM volumes. I've got DRBD up and working and almost have heartbeat (no hbstatus on one node, troubleshooting presently). My concern is what i've got to do to make live migration work with hvm. The documentation states: "Under these circumstances, you must use the traditional phy: device syntax and the DRBD device name that is associated with your resource, not the resource name. That, however, requires that you manage DRBD state transitions outside Xen, which is a less flexible approach than that provided by the drbd resource type." Is this much more difficult to set up than with the drbd: disk resource? Can heartbeat handle the state and xen transitions? I'm using CRM so can i use the Xen OCF with the drbddisk agent? If anyone has experience with similar situations i'd welcome the advice. -- TIA, Scott
