Read about tunefs if you wish, it may help you. I have a 6x250gb array (1.25tb RAID5). FBSD 5.2.1 refused to support a filesystem larger than 1.0tb, so i chunked it into 2 partitions to get around that problem and then I mounted them back using mount_nullfs so it appears as though all dirs are on the same partition in a single directory. Not sure if the 1TB filesystem limit problem is unique to me or not, but you will be fine with your .75tb no question. -- Matt Virus ("veer-iss") http://www.mattvirus.net
