If you are using GFS1, try to use GFS2, GFS1 will be deprecated and GFS2 has a lot of "auto-tuning" parameters as default and the performance is better as well. So, try to look at this document: http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.4/html/Global_File_System_2/s1-manage-atimeconf.html see ya -- --- Best Regards Carlos Eduardo Maiolino -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
