Solaris

Hi there,
Is it possible for OpenSolaris 2009 (or maybe Solaris 10) to work with the old AT&T Unix System V UFS file system? I recently install SysV, but I cant get files and programs to and from it. I would like to know if I could mount the Unix file system from Solaris, or format a floppy that I can use to transport files.
Any help is appreciated, Thanks.

On what hardware did you installed System V ?
What precise release ?

My hardware is a Compaq Deskpro EP Pentium 3. System V is installed on a 100MB hard drive. Solaris is installed on a 6 GB hard drive. It is a dual boot system.

The release is AT&T UNIX System V/386 Release 4.0 Version 2.1

Well, Solaris was built from SVR4.0 so there is a good chance it could still read (and possibly write) its UFS.

However, one potential issue is the partition id which is unlikely to be the one expected by Solaris for x86.

What says:

Code:

fdisk -v -W - /dev/rdsk/cxdyp0 | tail -5

(replace x and y by the values matching your SVR4 disk).

Heres what I got.

Code:

root@Admiral:~# fdisk -v -W - /dev/rdsk/c7d0p0 | tail -5
*

* Id    Act  Bhead  Bsect  Bcyl    Ehead  Esect  Ecyl    Rsect      Numsect
  99    128  0      2      0       9      34     883     1          300559    
  6     0    0      1      884     9      34     932     300560     16660

Solaris expects the 99 id to be 131 or 191. You might try to clone your SVR4 disk and experiment by replacing that 99 by 131 then see if the two slices show up.

Are you sure your old box is using UFS and not S51K ?

I am pretty sure I installed it with UFS, but not 100% sure. Even if it is S51K, I don't think there'd be a way to communicate with it, would there?
If it were anyother day, I would probably be up for that, but I have experimented with Unix all summer, and every experiment so far has failed. Im not real sure if Im up for trying much more hard disk work. What is the process for cloning the disk?
