For the uninitiated, would you be kind enough to elaborate the advantages of mdp? I have always created identical partitions on the raw disks first, and the used mdadm on top. I also create my partitions ~200MB smaller than raw disk capacity to ensure minor size differences between disks (eg. 160GB HDD from Seagate is not exactly same size as a 160GB disk from Samsung) will not prevent me from adding them to a raid set. Does mdp handle this scenario? - Raja _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
