A year or so ago I recall Jordan had an SGI DAT tape with 256k blocksize which wouldn't read on FreeBSD. Am wondering how this problem was eventually solved? Checking the archives I found mention of MAXBSIZE which appears to be defined in /usr/src/sys/sys/param.h (grep the whole /usr/src tree and you'll find a couple). The comments in param.h suggest this value can be increased without harm to existing filesystems but suggests any new filesystems created may require this value in the future to function. If I increase MAXBSIZE in param.h will it do what I think; allow reading those darned 256k-blocked tapes? Applications of interest: gtar, pax, dd, tcopy. If I can make this work I can replace a couple of Suns (which can't read the tapes either) with FreeBSD systems. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
