Dated but still good "Solaris x86 FAQ", (9.10) How do I mount a DOS partition from the hard drive?
You can run GParted from OpenIndiana's graphical environment via:
Starting GParted from Applications->System Tools->GParted Partition Editor
or clicking on the GParted desktop icon :-).
Here's what GPartEd looks like after a bit of partitioning...
Key to DOS filesystem use on Solaris is remembering that Solaris calls this
Magic filesystem type pcfs .
First determine the partition name:
Here I've used GParted to break the large disk into two parts, first for FAT32 and the
second for a ZFS file system.
So the disk we want to format is: /dev/dsk/c4t0d0p1
(this is actually a disk connected on the USB bus).
We can check on the disk information via iostat -En
root@openindiana:~# iostat -En

Yup, that is the muy macho 1 Terabyte, not 1 Tebibyte :-(, drive.
While Solaris does have an fdisk that can format DOS partitions,
it is along the lines of the original DOS FDISK. That is not too flexible.
Happily, OpenIndiana includes gparted (the graphical version) but strangely
FAT formatting isn't enabled.
But OpenIndiana also includes parted (the text version) which does include
FAT formatting. Interestingly it echoes each command and parameter typed in.

Doing a Control-R to refresh GParted we now see:
So now we can try to mount the partition:
root@openindiana:~# mount /dev/dsk/c4t0d0p0
mount: Mount point cannot be determined
root@openindiana:~#
Darn! apparently the new partition isn't known by the system.
Perhaps if we nudge the volume manager :-)
root@openindiana:~# volcheck
root@openindiana:~#
Wow! up pops the following window showing a nice file system, all mounted and such :-)
Let's check how that mounted:
root@openindiana:~# mount |grep c4t0

root@openindiana:~#
Look at all the mount options!
Notes:
Here we struggle with Linux style types: msdos,vfat,fat32,fat and dos :-(
How much free space is there?

NAME
pcfs - FAT formatted file system
SYNOPSIS
#include <sys/param.h>
#include <sys/mount.h>
#include <sys/fs/pc_fs.h>
int mount(const char *spec,
const char * dir, int mflag,
"pcfs", NULL, 0, char *optptr,
int optlen);
DESCRIPTION
pcfs is a file system type that enables direct access to
files on FAT formatted disks from within the SunOS operating
system.
Once mounted, pcfs provides standard SunOS file operations
and semantics. Using pcfs, you can create, delete, read,
and write files on a FAT formatted disk. You can also create
and delete directories and list files in a directory.
pcfs supports FAT12 (floppies) and FAT16 and FAT32 file sys-
tems.
[...]
Boot Partitions
On x86 systems, hard drives may contain an fdisk partition
reserved for the Solaris boot utilities. These partitions
are special instances of pcfs. You can mount an x86 boot
partition with the command:
mount -F pcfs device-special:boot directory-name
or you can use:
mount directory-name
if the following line is in your /etc/vfstab file:
device-special:boot - directory-name pcfs - no rw
device-special specifies the special block device file for
the entire hard disk (/dev/dsk/cNtNdNp0)
directory-name specifies the location where the file system
is mounted.
All files on a boot partition are owned by super-user. Only
the super-user may create, delete, or modify files on a boot
partition.
root@openindiana:~# man mount_pcfs # This explains :c suffix (it's the DOS C: drive!)
[...]
o A DOS logical drive on a hard disk expressed as
device-name:logical-drive , where device-name
specifies the special block device-file for the
whole disk and logical-drive is either a drive
letter (c through z) or a drive number (1 through
24). Examples are /dev/dsk/c0t0d0p0:c and
/dev/dsk/c0t0d0p0:1.
