The whole cycle of taking the power off a blade including login to the service processor is less than 1 ms. Delay or lack thereof is not a problem. The transactional nature of the processing is the issue. > > Regards, > > Chris Jankowski I forgot to mention; Fence calls can only be sent by nodes with quorum. So a race condition should, as I understand it, be a concern with 2-node clusters only. I'm not entirely sure though on how quorum is determined at the time of partitioning. That is, say you have a three node cluster, and one node disconnects. I need to verify that it checks to see if it has quorum before sending a fence call. I expect that is the case though. -- Digimer E-Mail: digimer@xxxxxxxxxxx AN!Whitepapers: http://alteeve.com Node Assassin: http://nodeassassin.org -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
