Do you use drbd primary/primary and live migration? If it works, which version of drbd and which kernel/xen version are you using? What is in domUs? I have tons of problems with this setup: jittery domU clock, random domU crashes (luckily no dom0), network going down randomly in domU after migration, etc, but have no clue what could be the problem lvm, drbd or xen, or all three. -- To sto si frustriran, zavidan tko zna na cemu i sto ne vidis dalje od svoje guzice je tuzno.
