[Gluster-users] Glustertests with 3 Nodes and dispersed Volumes are slow
Hi everbofy there, I am J?rg from Germany and love to build good solution with high intelligent Software in a simple way. I come on your grate software by evaluating my environment and think that I have lot to much hardware , So I try to move my NFS storage for my KVM Servers to the Servers themselves. It there are easy qcow2 images. I want the to run from local (cluster) disk. So, I start building a lab for testing my idea. The first few tests were very fine wie distributed storage and also replicated. I came a long to begin loving your work and start more tests. I read about erasure code - a raid5 style setup. So I install 3 Cents mashines and build a build a dispersed volume over 3 servers with 1 Brick on each. What I see on my simple tests was very hard. Only 40 MB/s writespeed on the local mounted glustervolume. I tested a lot - also on high perfomance hardware. But I didn't find a solution. Have you any idea why the performance is so slow? Even with a 4 Server... All are connected over 1 Gbit/s Network. Thanks for your answer... -------------- next part -------------- An HTML attachment was scrubbed...
