ffs2

[knasbas]

Ive read the faq 14.7 about large drives but im not quite sure i understand howto.
I got this 1.5tb seagatedisk and it has to be ffs2 aparently since ffs1 cant handle more then little less then 1tb. Its not meant for /, /var,/usr but more like /storage.

how do i format the disk?
doing man newfs give me this:

-t fstype Set the file system type of which file system you wish to
create. newfs will be smart enough to run the alternate
newfs_XXX program instead.

Will it be smart enough so i just write newfs -t ffs2 wd4 ?

At the bottom of faq14.7

The boot/installation kernels only support FFS

Do i need to add ffs2 to my system somehow or do i misunderstand the context?

You need to use -O 2 to create a FFS2 filesystem, from newfs(8):

     -O filesystem-format
                 Select the filesystem format:

                       0    4.3BSD format file system.  This option is primar-
                            ily used to build root file systems that can be
                            understood by older boot ROMs.
                       1    Fast File System (the default).
                       2    Enhanced Fast File System (FFS2).

Thanks, onto the next problem:
How do I mount it?
After checking man fstab and mount I cant see any ffs2 options?
quote from 'man fstab'

cd9660 An ISO 9660 CD-ROM filesystem.
ext2fs A local Linux compatible ext2fs filesystem.
ffs A local UNIX filesystem.
mfs A local memory-based UNIX filesystem.
msdos An MS-DOS FAT filesystem.
nfs A Sun Microsystems compatible Network File System.
ntfs An NTFS filesystem.
procfs A local filesystem containing process information.
swap A disk partition to be used for swapping.
udf A UDF filesystem.
vnd A VND image file.

mount(8) or mount_ffs(8) should mount it without trouble. e.g.:

# newfs -O 2 sd1a
# mount /dev/sd1a /mnt
# umount /mnt
# mount_ffs /dev/sd1a /mnt

So treat it like any other FFS file system.

I know I know...posting to a 3 year old thread...

But newfs -O 2 /dev/sd1a does not work for me.

I need to specify the "raw" device name:

newfs -O 2 /dev/rsd1a

Hey, thanks for catching my typo. You're right, raw or the short form are required for newfs. I'll correct it now.
