From what I've read, md is a better way of going than mfs. I don't want this to be able to swap out. So far I'm having trouble getting md to store anything larger than ~90meg .. OS: FBSD 4.3-S relevant kernel config: options MD_NSECT=800000 Then I do a: disklabel -r -w md0 auto newfs /dev/md0c mount /dev/md0c /mnt Then.. while trying to copy over a large file.. it stops.. locks up the term.. (but not the entire system) .. I can't kill the cp proc, end up having to reboot to clear it. > df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/twed0s1a 2032623 287113 1582901 15% / /dev/twed1s1e 2032623 488229 1381785 26% /news /dev/twed0s1e 544066012 171091592 329449140 34% /news/spool/news/bin01 /dev/twed1s1f 544066012 172257468 328283264 34% /news/spool/news/bin02 procfs 4 4 0 100% /proc /dev/md0c 387607 90265 266334 25% /mnt It always gets to the exact same number of blocks... 90265 .. anyone have an idea?
