First, by experiment, I found that the standard filesystem (NetBSD-0.8
anyway) uses 4096 bytes/inode. This is the reason you run out of
inodes in a news spool dir.
I found -1 3072 to be very satisfactory for my news spool.
Filesystem kbytes used avail capacity iused ifree %iused Mounted on
/dev/sd2a 281039 211281 69758 75% 66717 25441 72% /v
It is important not to have too many inodes created in the data space, or you
lose a considerable amount of disk space. As you can see by the percentage
figures above -i 3072 has a very close correspondence with data space used.
Another thing you might consider, if you are low on disk space, is to
reduce the space usable only by root. This defaults to 10% I've set
mine to 2% with no apparent ill effects. When you increase the number
of inodes you will lose disk space, so I found this was necessary for
my tiny little news spool drive. This is also done using newfs:
newfs -i 3072 -m 2 /dev/sd2a
should do it for you. PS you must unmount the drive first.
Now all you have to work out is where to put your news spool while you
newfs the disk. ;-(
