Hi all. A long while ago now, I spoke with someone (who I'll keep anonymous) about the possibility of suspending a cluster to disk. The person seemed to be reasonably excited about the idea, since it would potentially be quite useful in a power outage situation with limited UPS capability (particularly where the state of computations couldn't easily be serialised and restarted later). I'm now in a situation where I don't have a lot of time to work on it, but am interested in starting to make modifications to Suspend2 to add such support. Before I do it, though, I wanted to ask whether you guys as a whole would be interested in such support, or whether you think I'd be wasting my time. At the moment, I'm imagining starting with the simpler aspects first, implementing a means to initiate suspending from a master node and synchronise the suspending and resuming of slave nodes to local storage on each node in such a way that if one fails, all abort suspending, and they all resume together too. After that, I'd like to work toward supporting suspending to shared storage. Are there other issues I might have overlooked? Clustering is all new to me.
