You are correct about the 2G, on a lot of Alpha models it is less than that (IIRC..) > Third, is this a machine ram size problem or a disk volume size problem? = =20 > The original post was about a 131G FC volume and calculating the wrong=20 > number of sectors and the wrong sector size...

But not on amd64 as we do not currently have such a machine :) W/ --=20 Wilko Bulte wilko@FreeBSD.org --DocE+STaALJfprDB Content-Type: application/x-pkcs7-signature Content-Disposition: attachment;
