Hello all, We're using DRBD and Heartbeat to provide filesystem replication and failover in a VMware environment. Heartbeat seems ill-suited to this environment, since there aren't many options for alternate communication paths (e.g., no serial connectivity), so no dopd. A network interruption invariably ends up with DRBD in a split-brain situation, which means that failovers stemming from connectivity loss require manual intervention. From my perspective, there are obvious solutions: - Quorum disks. This would work great, since we have shared storage, but this is tragically not implemented by heartbeat. - STONITH via VMware. This might work, but the vmware-vi STONITH module distributed with VMware is non-functional. What are other folks doing? Automatic split-brain recovery is probably our best option in the short term, but is anyone doing something more reliable? What about "cman" and the associated tools -- I understand that this has support for quorum disks. Does this offer a similar feature set to Hearbeat? Thanks for your input, -- Lars
