In the mdadm manpage under --layout, it specifies that the default is --layout=n2, which is two copies, and you can change the number to a maximum of the number of devices in the array. So, --layout=n3 would get you three copies, etc. Gregory -- Gregory K. Ruiz-Ade <[email protected]> OpenPGP Key ID: EAF4844B keyserver: pgpkeys.mit.edu
