Hi all, while testing my first rhcs4 cluster, I noticed some poor performance while tarring data from a gfs volume to a local disk from both nodes at the same time. I deceided to have a closer look. Here are the bonnie++ results: http://jure.pecar.org/gfs/ I don't know what to think of these ... but I doubt it's normal for performance to go down by an order of magnitude when both nodes are doing some i/o to the shared file system ... I'd like to understand what's going on here, where&how to look for bottlenecks and how to get rid of them. Thanks, -- Jure Pečar http://jure.pecar.org/ -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
