I have task to search old external harddrives for a specific file. The drives were used with a Sun Ultrasparc 1, so they are pretty old. I have 4 drives, and I managed to mount one of them in a Sun which uses Solaris 9. I cannot mount the other ones because this was the only case were my cables fit. So I found an SCSI controller and put it into my linux machine (Ubuntu 10.10) and connected the drive. I used the one drive I had access to, because I backuped everything and I know it did work.

Now, the problem is, that I cannot mount it in ubuntu. using {fdisk -l} I get

Festplatte /dev/sdc („Sun disklabel“): 30 Köpfe, 91 Sektoren, 2878 Zylinder Einheiten: Zylinder mit 2730 × 512 Byte

/dev/sdc3p1 0 2878 3928470 0 Unassigned /dev/sdc3p3 0 2878 3928470 0 Unassigned}

I think the main problem here is "Unassigned".

If I use dmesg | grep sdc I get[ 5.842160] sd 5:0:0:0: [sdc] Spinning up disk....ready [ 10.254764] sd 5:0:0:0: [sdc] 7866080 512-byte logical blocks: (4.02 GB/3.75 GiB) [ 10.257375] sd 5:0:0:0: [sdc] Write Protect is off [ 10.257381] sd 5:0:0:0: [sdc] Mode Sense: 8f 00 10 08 [ 10.262421] sd 5:0:0:0: [sdc] Write cache: disabled, read cache: enabled, supports DPO and FUA [ 10.273597] sdc: sdc1 sdc3 [ 10.468921] sd 5:0:0:0: [sdc] Attached SCSI disk

This is the right disk...

Any Ideas how to mount in properly? Thx.

In fact, I finally found the command to do it. In case somebody wants to know:

mount -oufstype=sunx86 -o ro

works very good.

That's odd. As you created your disk on a UltraSPARC 1, that should have been -o ufstype=sun (UFS big endian), not ufstype=sunx86 which is for filesystems created on a x86 machine, i.e. little endian UFS. Perhaps the mount command is smart enough to detect the mistake. – jlliagre Jan 21 '11 at 22:01

I do not think that the default kernel in Ubuntu supports the Sun disk layout.

I would suggest getting an OpenSolaris Live CD and boot on it on your PC. Hopefully it will recognize and mount the drive.

Unfortunately, unlike Linux, Solaris doesn't support cross architecture mounts with UFS. – jlliagre Jan 21 '11 at 22:02
Hi, I tried this, but neither my laptop nor my linux machine can read or boot from the opensolaris boot cd. – Arpad Jan 22 '11 at 6:57
@arpad, there is two architectures, intel and Sparc. You need the correct one. – Thorbjørn Ravn Andersen Feb 28 '11 at 10:16
@jliagre, I didn't know that. – Thorbjørn Ravn Andersen Feb 28 '11 at 10:18
