Thank you Robert for your answer that cleared up all my doubts. I tryed to use GNBD on non-clustered student-PC as you suggested and also using the -c option with gnbd_export on server and -n option with gnbd_import on PC but it doesn't work because of GFS filesystem that requires the cluster lock-manager. At the end i'm using NFS, can you suggest any other possibility? Fedele -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
