Hello,
I have a need for a rather large ramdisk. 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

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?
Please resond offllist since I'm not on hackers.. or you can answer this in
fbsd-questions ;)
Thanks,
Jason
