That doesn't exactly help me. I already know that text. My problem is that there are mentioned different maximum values for the size: FAQ: 2TB on 32bit machines and 512 bytes block size (Where do you read of 1TB???) My final question is/was: Is the limit (on kernel's side) to be raised in some *near* future? MfG, JBG -- Jan-Benedict Glaw . jbglaw@lug-owl.de . +49-172-7608481
