Re: Large drive support (IDE/SCSI)

[chuck <chuck@Yerkes.com>]

I believe I had a 200 Gig "disk" (raid box) mounted on my
Sparc, if briefly.  The partition was smaller (30G?) cause
it took too long to newfs on a sparc 2.

SCSI.

Special parameters?  I'll take McKusicks thoughts on free space:
(paraphrasing):  when we came up with 10% free, large disks
were 30-40 MB.  The idea of someone using 10% on a 10G or 50G
disk is a little scary: They are reserving 1000 times the space
that FFS needs to do it's book keeping.

So that in mind: my 18G was newfs'd with "-m 1" (1% or 180Meg free).
this doesn't use large files or anything unusualy, just the regular
home directory/source sized files.  For a partition full of large
graphics, I'd certainly change the tuning on that (like cranking up
the blocks/inode, etc).  Same idea as making NEWS partitions with
more inodes, smaller file chunks, etc.
