Hi, I have a G5 imac and an external firewire hard drive.

Using the livecd, I would like to mount both the internal drive /dev/sda3 (hfs/hfsplus) and the external firewire drive (ext3,reiserfs) for backing some stuff up before making this system dual boot.


Couple of problems stopping me though though:

1.
I can't mount /dev/sda3.

mac-fdisk reports the filesystem type as hfs...

Code:
mount /dev/sda3 /mnt/whatever
returns 'Must specify filesystem type'
Code:
mount -t hfs /dev/sda3 /mnt/whatever
returns 'Unknown filesystem type 'hfs''
Code:
mount -t hfsplus /dev/sda3 /mnt/whatever
returns 'Unknown filesystem type 'hfsplus''

2.
There is nothing in /dev for the firewire drive

I've tried giving 'dofirewire' as a boot option and loading the sbp2 module



Any ideas?

probably you have to "modprobe" all the hfs* modules.

Code:
man: command not found


I thought there was no man on the livecd - perhaps I have just been using fudged cds all my gentoo life.

actually, the md5sum checked out and the disk verified correctly when I burnt it.

yeah, I thought that most likely but I couldn't see any in /lib/modules/



Any ideas about the firewire? I'm assuming somebody else with an imac G5 has firewire working, even if not with the livecd. If so...how?

Do you check the options of the liveCD before booting?? Maybe you have to pass some parameter to the booting or load a different kernel. Chackout when you boot the cd, f1 is help and f2 is options i tihnk.

Try that

I wish!

it uses yaboot as a bootloader which allows me to tab to view available kernels and that's it.

also gunzipping /proc/config.gz reveals that
Code:
CONFIG_HFS_FS is not set
CONFIG_HFSPLUS_FS is not set



on the firewire front, things are more promising.

I've noticed in dmesg that it gets to the point of
Code:
usb 2-3: new full speed USB device using ohci_hcd and address 2
but scsi emulation never kicks in to take it to the next stage

If I turn it on once the system has booted, then it doesn't even get that far, spewing out repeated

Code:
Error parsing configrom for node 0-00:1023
amongst
Code:
got invalid ack 252 from node 65472 (tcode 4)
but I thought 'ack' was to do with tcp/ip flow control


sigh

which liveCD do you use?
I got a 2005.0 minimal, which works pretty well with my firewire hdd attached to my iBook G4
even without passing firewire stuff to the kernel... I think one time i did "dofirewire" and I had problems.
but I think you are booting a G5 labeled kernel, are you?

also, when udev works, your FW-hdd should be 'hot-plug'able, have you tried to attach it after the liveCD finished booting?


btw: the usb stuff has nothing to do with your firewire disk, it's probably an intern device or your keyboard
("Full Speed" is USB1.1=12Mbits per second.. a full speed usb-disk wouldn't be nice for back ups ;))
the only thing they have in common is using scsi-emulation for blkdev-access

I've been trying with install-ppc64-minimal-2005.1.

Reconnecting after bootup makes no difference.

I am currently downloading the ubuntu livecd. All I'm really after is copying these files.



It's one of those problems that makes me wish I had a bunch of free time to throw at and learn some stuff!


Update:
The ubuntu livecd seems to load fine, right until the xserver is started - when my bluetooth keyboard and mouse are no longer responsive. Argh!



So, how do I get hfs/hfsplus support on the livecd (are the 'non-minimal'/32-bit cds any different?).
