What are your thoughts on the following setup? 2x physical nodes - identical DRBD latest 'pre' 0.8 source Fedora Core 6 host OS/dom0 (on both nodes) Crossover cable between the two nodes with 10.0.0.1, 10.0.0.2 respectively purely for DRBD chatter. Metadata (of DRBD) stored on a separate disk on each machine (/dev/sda5). DRBD 'source' drive is /dev/sdb and target drive is /dev/drbd0 Now, on top of this I run pvcreate /dev/drbd0 then the usual vg, lv create tools etc. to create separate LV '/' partitions for each Xen guest OS. Xen guest images will run alternately on each physical node; Node1 Node2 Xen1 Xen2 Xen3 Xen4 etc. Therefore Xen1 will never write to the same LV as Xen2. But then there is the question of LVM meta data etc. logs and caches etc. of all these layers - how do you think DRBD will handle it without the use of OCFS or GFS as the choice of FS on the Xen LV drives? Worth a go? (Of course DRBD is set to allow-two-primaries at the moment). Jim -- James Vanns Systems Programmer Framestore CFC Ltd.
