Добрый день!

Есть кластер, состоящий из 2х серверов. Настроен drbd, xen и heartbeat.

При попытке мигрировать одну виртуальную машину на другой узел кластера происходит следующее:
dom0a:~ # crm_resource -M -V -r dns2 -H dom0b
crm_resource[27133]: 2011/08/18_09:17:41 WARN: unpack_rsc_op: Processing failed op xen_r5_start_0 on dom0b: unknown error

И ничего не мигрирует. Куда копать?

Вот конфигурация crm
