i want to know what's the difference between mksf and newfs

[常有慈悲心]

is mksf a old command?

I guess you wanted to know the difference between mkfs (not mksf) and newfs. however, here is both.

mksf vs newfs
=============
both are used for completely different functionality. mksf creates device files with custom attributes. newfs creates filesystems on logical volumes/whole disks

mkfs vs newfs
=============

As far as my understanding goes, newfs is just a wrapper for mkfs. newfs inturn calls mkfs and get the job done. You have very good control over the filesystem metadata structures with mkfs but u r better off using newfs.

First try the man pages.

mksf = make special file. That can be used to create new device files if you need to.

newfs = new filesystem. That creates the filesystem layout on a new logical volume.

# man mksf

# man newfs

[Michael Tully]

mksf: Makes special files for most/all types of devices.
newfs: Creates a new file system on top of a designated logical volume.

thanks,
i write wrong.
it's the difference between mkfs,newfs

.
can i use mkfs to create a file system directly?

[Sundar_7 · Accepted solution]

Sure you can use mkfs to create the file system directly, though I am not aware of any problems you might face.

But preferred and suggested way would be to use newfs.

Hi,

A new filesystem can be created using either the mkfs command or the newfs command. newfs is actually a more user-friendly front-end to mkfs.

Also, check out this thread (same topic has been discussed there as well):

mkfs is called by newfs.

mkfs allows you more options when creating file systems.

For example, say you have a backup server running 11.0 and a database server on 11.i.

Well, default filesystem type is different - and you won't be able to mount a 11.i filesystem on 11.0 - unless you created the file system on 11i like so:

mkfs -F vxfs -o largefiles -o version=3 /dev/vg30/rsapdata01
