I've made the following change to newfs man page locally. Please comment upon the style of the change as well as its technical accuracy. Style comments should be sent to [EMAIL PROTECTED] with [EMAIL PROTECTED] cc'd (I'm not on doc@). Technical content comments should be sent to [EMAIL PROTECTED] The change does two things. First, it removes the warning about not being able to boot off file systems that aren't 8k/1k. There was a thread here that reported this was no longer the case and that both 4k and 16k block sizes work. The second change gives an example of using a 16k block size and a 4k fragment size with 100 cylinders per group with a note that this is expected to give better performance for large file systems. Comments about changing the default should go to /dev/null, or be discussed under a different thread. :-) Warner Index: newfs.8 =================================================================== RCS file: /home/imp/FreeBSD/CVS/src/sbin/newfs/newfs.8,v retrieving revision 1.28 diff -u -r1.28 newfs.8 --- newfs.8 2000/11/20 16:47:42 1.28 +++ newfs.8 2000/12/17 06:15:48 @@ -335,18 +335,20 @@ .El .Sh EXAMPLES .Pp +.Dl newfs -b 16384 -f 4096 -c 100 /dev/ad3s1a +.Pp +Creates a new ufs file system on ad3s1a. +.Nm +will use a block size of 16384 bytes, a fragement size of 4096 bytes +and have 100 cylinders per cylinder group rather than the defaults. +These values are tend to produce better performance than the defaults +for file systems larger than about 5 gigabytes. +.Pp .Dl mount_mfs -s 131072 -o nosuid,nodev /dev/da0s1b /tmp .Pp Mount a 64 MB large memory file system on /tmp, with .Xr mount 8 options nosuid and nodev. -.Sh BUGS -The boot code of -.Fx -assumes that the file system that carries the -kernel has blocks of 8 kilobytes and fragments of 1 kilobyte. -You will -not be able to boot from a file system that uses another size. .Sh SEE ALSO .Xr fdformat 1 , .Xr disktab 5 , To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
