That limits you to 2GB files. BSD bit the bullet and fixed that problem long ago. IIRC the limits of UFS1 are 1TB per file system with 512k blocks (2^31 * 512k) due to use of a signed value in some places. The file system limit should be close to 1TB. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
