Hi, everybody: I have a machine and centos 5.2 installed on it. I have created a RAID5 array with five SATA disks, then I create LVM on this array. #pvcreate /dev/md0 #vgcreate myvg /dev/md0 #lvcreate -n mylv myvg As you see, I want to use XFS or ReiserFS on "mylv" volume. I wonder if there are some alignment settings when creating such file systems so that a better R/W performance can be achieved. Thx in advance. -- The simplest is not all best but the best is surely the simplest! -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
