Filesystems, Disks and Memory

Hi all

I have an NCR UNIX hard disk I need to mount it on a Linux box
The FS Type in fdisk on linux is '63' for the partition
How can i mount on my linux box ?
what is kernel module i needed ?

I think you should just be able to mount it normally with mount or in /etc/fstab as SysV filesystem once you recompile your kernel.

When you get to "System V and Coherent filesystem support", answer yes.

In fdisk, type 63 comes up as "GNU HURD and SysV", so I think if you compile that support into the kernel you should be good to go.

You used to be able to just mount SysV filesystems, but support for that isn't included in stock kernels anymore a/o the 2.4 or 2.6 kernels, AFAIK.

YMMV, but I'm interested to know if that works coz I don't have any old UNIX disks laying around anymore, having migrated everything ages ago and dispersing with the hardware, so lemme know how it goes k?

Kindest regards,

Bradley

Iam recompile kernel and add support for SYSV but fail to mount as sysv
[root@yasser yasser]# modprobe sysv
[root@yasser yasser]# mount -t sysv /dev/sda3 /mnt/ncr
mount: wrong fs type, bad option, bad superblock on /dev/sda3,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

[root@yasser yasser]# dmesg |tail -1
VFS: unable to find oldfs superblock on device sda3

You should first determine which file system you have.

He said he had a type 63 filesystem - so once he compiles support for SysV filesystems into the kernel he should be able to:

Code:

mount -t sysv ........

Yes it is appear as SYSV on Linux But cannt mount as sysv !!!

NCR UNIX is a spin of SysV UNIX. So it should be a Sysv filesystem (I think).

I noticed you modprobed the kernel mod instead of compiling SysV/Coherent FS support into the kernel directly. Dunno if that has anything to do with it.

A couple of things then....

Maybe if you pick up an old distro with a 2.0 or 2.2 Kernel, do a quick install, and try that, or maybe check with NCR (or whomever they've become now - prolly will not yield much though).

The last thing I can recommend to you, if your data is important enough for you to spend the money, is to take the disk to Data Mechanix in Irvine, California (Data Mechanix | Data Recovery).

Their phone number is: 800.886.2231 and although it's been many years since I've had to have a clean room pull data from a drive, they always did me right, and I believe the owner's name is Craig - but don't quote me on that.

If you get him on the phone, he might even offer you a couple of suggestions as to how you might mount it.
