Hi,
We are now checking about what we should do on vm fail-over. Concerning this, does anybody know about any danger about data consistency when we are using shared disk? What I'm concerning is if crashed VM-side host is still holding buffered data, starting a new VM instance on another node may result in file system corruption. This problem may similar to live-migration but little bit different in the sense that VM is crashed -> cannot do anything from that point. How about the combination of old or new guest OS and the following settings? - writethrough - writeback - none If needed, we'll do sync by HA-side scripts before starting a new VM instance.
